 SiE, — I have the honour to submit a report of the Bow River Power and

 SESSIONAL PAPER No. 25e 
 
 A. 1915 
 
 Water Power Branch, Ottawa, August 29, 1914. 
 
 W. W. Cory, Esc, C.M.G., 
 
 Deputy Minister of the Interior. 
 
 Sir: — Conservation of the waters of the Bow River is of the utmost moment 
 f r upon it directly depends the agricultural and industrial prosperity of a very 
 large area of southern Alberta. Rising in the high and remote regions of the 
 Rocky Moimtains National Park, and, with its many tributaries, furnishing the 
 most interesting and attractive feature of this world-famed scenic park, it 
 emerges from the park only to be harnessed to supply energ>' for transmission 
 many miles away to the City of Calgary for municipal purposes, street lighting, 
 tramways, and for general commercial and industrial use. After furnishing 
 this hyd velectric energy, the same waters have, by irrigation, converted 
 thousands of acres of otherwise useless land into the most fertile and fruitful 
 tracts within the Province. 
 
 At "first blush" it would appear that the two important uses of this water 
 for irrigation, and for power, would result in serious conflict of interest. For- 
 tunately the irrigation requirements occur during high water stages of the river, 
 and storage on its upper waters would make it i)ossible to conserve enough 
 of the flood flow, not required for irrigation, to equalize the low flow during the 
 winter months that may be necessary for power purposes. The present use 
 and distribution, and the future conservation, of the water resources of the Bow 
 river basin, constitute one of the most important problems before the Depart- 
 ment of the Interior. In some of its phases this problem has already been solved, 
 while in others it av.'aits solution, although a beginning has been made, and the 
 lines of practicable progress have been fairly well marked out. 
 
 Realizing the importance of the Bow river waters to every phase of the 
 development of the district through which it flows, and of the utmost necessity 
 of having a practicable conservation scheme worked out and put into pra,. oe 
 without delay, the Dominion Water Power Branch has made a thorough investi- 
 gation of the water resources of the Bow River basin above Calgary. These 
 investigations have been carried on to completion with all reasonable thorough- 
 ness and every possible despatch under the immediate direction of Mr. M. C. 
 Hendry, B.A. Sc, who has acted throughout with the continuous advice and 
 assistance of Mr. C. H. Mitchell of the Consulting Engineering firm of C. H. and 
 P. H. Mitchell, Toronto. They have been surprisingly gratifying, showing that 
 it is economically feasible to so regulate the flow of the Bow River, by means of 
 storage works in its upper waters, as to warrant the developn'ent at six power 
 sites of over 45,000 continuous 24-hour W.H. P., all within 50 miles of the City of 
 Calgary. At the same time it has been shown, that the using of these waters 
 for power purposes r'^ove Calgary need not conflict with the consumption 
 of the same water be', v. Calgary for irrigation purposes; rather would the regu- 
 lation proposed for power purposes be a distinct advantage to the extension of 
 existing irrigation systems to their ultimate capacity, and also insure in the 
 future the instigation of additional irrigation projects. 
 
 Owing to the importance of Mr. Hendry's investigations, and of their direct 
 bearing on the industrial development of central Alberta, I would reconime'id 
 that they be published for general distribution as "Water Resources Paper No. 
 2" of the Dominion Water Power Branch. 
 
 Mr. Hendry's report is submitted for this purpose. 
 Respectfully submitted, 
 
 J. B. CH ALLIES, 
 Superintendent, Dominion Water P(>wer Branch.

 CHAPTER I. 
 
 SUMMARY OF INVESTIGATIONS AND SURVEYS. 
 
 1 
 
 INTRODUCTION. 
 
 The Bow river is a typical mountain river. West of Calgary, it drains an 
 art'a of 3,138 square miles, of which that part above the Kananaskis falls, 1,71U 
 square miles in extent, may be considered to lie wholly in the Rocky mountains. 
 It has a very steep slope, and in steveral places falls occur. The head-waters of 
 the river lie at an elevation of about 6,500 feet above sea-level. The flow of 
 the river is typical of all mountain rstreams, subject to sudden variation and 
 greatly influenced by conditions of temperature. During the winter months 
 the flow is much reduced, but in the hot summer months of June and July the 
 floods occur and the variation between high and low water is very great. While 
 no direct gaugings are available of flood discharges, it has been computed from 
 levels taken by the Canadian Pacific Railway Company at Bow bridge and 
 Kananaskis bridge, that, at Kananaskis falls, just below the mouth of Kananaskis 
 river, flood of 45,000 c.f.s. has occurred. A low-water discharge of 550 c.f.s. 
 has b»'tii recorded at the same point. 
 
 What may be termed the power-producing section of the river is a stretch 
 iibout 30 miles long, well within feasible transmission distance of the logical 
 power market, Calgary. The growth of that city is phenomenal, and as it is the 
 distribution centre for a large district, many small manufactories have located 
 there; others no doubt would follow the advent of cheap power. The city has 
 control of its public utilities, that is street railway, waterworks, electric light, 
 ftc, .so that it is itself in the market for power in rapidly increasing amounts. In 
 addition to the city, there are other possible customers,— the Canadian Pacific 
 Railway Company have recently erected large car shops near the city; tlicrc 
 .•ire also two cement plants, and some plants handling clay products. 
 
 Depahtmental Policy. 
 
 The constant growing demand for cheap power for municipal and manufac- 
 turing purposes has made the questio- of water-power development in Western 
 < anada one of vital importance. Fortunately a well-considered and cautious 
 I)olicy of water-iK)wer administration has Iwen determined upon, and regulations 
 l)ut into force which afi'ord every reasonable protection to the public in the way 
 of rentals, periodic revisions, control of rates, limited grants, etc., and at the same 
 tiine foster legitimate private initiative and afford reason'il.|» financial rewards for 
 private skill and efficiency. The Water-power Regulations are .set out in full in 
 -Vppenclix V. So far as the administration of the regulations is coi hI. it is 
 
 the jiolicy of the department to afford every poswible iissistance to tl. develop- 
 ment of water-powers which have any reasonable assurance of economic 
 utilization. In fact, the practice of the department is to carrv on suflicient 
 in. ligations by way of field survey«i, etc., as will make it po-'sil .e for the 
 department to prove the economic features of pow «r possibilities that might be 
 expected to be possible of comiucrcial dcvclopmeiu within a rtu.MtUable time. 
 Such investigations have been carried on throughout the West, but more pir- 
 ticularly on those rivers where there are several power sites all -.ithin range of 
 iinmeiliate use. 
 
t DEPMtTHmT OP THE INTERIOR 
 
 5 GEORGE v., A. 1915 
 
 It is considered that such investigations should precede the authorization 
 of all important power or storage projects and, furthermore, that proper Gov- 
 ernment supervision and control of the construction and maintenance of all 
 developments is the only safe method of intelligently initiating construction 
 and maintaining an adequate system of river improvement for power purposes. 
 Such investigation, supervision and control by departmental engineers of 
 recognized competence and character not only secures the scientific treatment of 
 power rivers as a whole, but the safe and economic execution of the various com- 
 ponent parts of a comprehensive system of improvement. 
 
 Necessity for Investigation. 
 
 The Bow river was the first of the Rocky Mountain streams to be investi- 
 gated by the Department of the Interior as to its power-producing and storage 
 possibilities. The department was called upon to deal with certain applications 
 for power rights on the Bow and on the Elbow rivers; before these could be 
 dealt with in a satisfactory way, it was necessary to have definite and independent 
 information of the situation; this was especially necessary on account of there 
 being overlapping or conflict between several of the applications, as on the 
 Elbow river and on the Bow river at Kananaskis falls. 
 
 The growing demand for cheap poWv.-, due to the rapid development of the 
 district of which ("algary is the centre, also necessitated steps being taken toward 
 gathering general infomtation on the sul)ject. 
 
 It has been sht)wn above that the fluctuation in the flow of the river is 
 great; in order, therefore, that the river might be improved from a power- 
 producing standpoint, some method of regulation and control was necessary. 
 Under natural conditions, the amount of power produced by the river during the 
 six months' period of low flow, would be but a small part of that amount capable 
 of being produced during the remainder of the year, and it was with a view to 
 gathering information in regard to these questions that the investigations 
 embodied in this report were instituted. 
 
 ()R(iANIZATION AND ScOPE OK INVESTIGATION. 
 
 Ill April, 1911, the work in the district was organized. The field work wa« 
 carried on under my immediate direction as Chief Engineer, with the general 
 advice and assistance of Mr. C. H. Mitchell, CE., M. Inst. C.E.; M. Can. Soc. 
 C.E.; of the Consulting Engineering firm of C.H. & P.H. Mitchell, Toronto, 
 and one of th; Board of Consulting Engineers to the Dominion Government, 
 in connection with water-power matters in Western Canada. The work to be 
 undertaken was comprehensive in its scope, calling for an investigation into 
 the power and storage possibilities on the Elbow river, and the Bow river west 
 of ( 'algary and including all its tributaries. Consequently a reconnaissance of 
 the whole basin was made with surveys of all pos.xiblc sites and storage ba sins. 
 In addition, the inspection and approval of plants existing or building in the 
 district was included in the work. Owing to the lack of ruK-off data at critical 
 points in the river and its tributaries, aclditional gauging stations were estab- 
 lished; this was done by the Irrigation Branch, at the instance and expense 
 of the Water Power Branch. Prior to the work of the Water Power Branch, 
 most of the work of stream gauging had been carried on only during the open- 
 water season, and little data was available »s to the flow during the winter 
 u»unth.s. The former stations, and those established ai this time for these 
 investigations were:-

 Reconnaissance. 
 
 The reconnaissance of the following was made by Mr. (". H. Mitchell and 
 the writer: Elbow river, Kananaskis river and Kananuskis lake.s, Spray river 
 and tributaries and the Spray lakes, Bow lake, Hector lake, Pipestone creek, 
 Johnston creek. Uedearth creek, Brewster creek, Baker creek, Forty mile creek, 
 and Ghost river were visited by the writer alone. A reconnaissance, pre- 
 liminary to the survey on the power-producing portion of the Bow river was also 
 made. The different creeks and lakes examined in these trips were either elimin- 
 ated as being unsuitable for power or storage purposes, or accepte<l as feasible 
 and some general scheme for development settled on. In thi latter case, a held 
 party was then put on the ground to carry out the investigations in greater or 
 less details. 
 
 Surveys. 
 
 Survevs were made of the following: Elbow river, between the east boundary 
 oi section "14, township 22, range 6, west of the 5th merithan and the north 
 boundary of section 29, township 21. range 6, west of the 5th meridian, particular 
 attention being given to the topography in those portions >n/i'';V'"^i- ^^J ^•*' 
 and part of 14, township 22, range 6. During the seasons of 1911-12, a topo- 
 graphical survey was made of about 30 miles of the Bow nver from the C anadian 
 Pac-ific Railway bridge above Kananaskis falls down, particular attention being 
 given to the several power sites. Also topographical surveys were made of Bow 
 lake, lake Minnewanka and the basin of the Spray lakes, with a view to the 
 creation of storage. 
 
 Resilts of Surveys. 
 
 The results of these surveys are summarized in the following tables 2 and 3: -

 Results of Storage Investigatio.w. 
 
 The effect of storage on the river can best be noted at two points, one of 
 which may be taken as at the Calgary Power Company's plant, at the Horseshoe 
 falls, and the other below the mouth of the Elbow river. At the former site, 
 the effect of all the storage on the Bow above Calgary is noted; and at the 
 second, the effect of the storage on the Bow and Elbow combined. The mean 
 flow for the low-water months, as recorded at Horseshoe falls, has been found to 
 be a.s low as 745 c.f .s. ; by means of the storage that has been, and may still be 
 created, it is anticipated that this can be raised to at least 1,500 second-feet. 
 Below the mouth of the Ghost, this would be increased to 1,600 c.f.s. At Cal- 
 gary, below the mouth of the Elbow, the storage on that stream becomes effective 
 and it is expected that a flow approaching 2,000 c.f.s. may be obtained. ' 
 
 The effect of storage upon the power output of the river over that due to the 
 natural flow, may be seen by a glance at the following tables, Nos. 4 and 5:—

 Estimates of C^gst. 
 
 Estimates of cost have been prepared that provide for the complete develop- 
 ment of the three storage basins, including one already bi"'t - four additional 
 power plants and new duplicate transmission lines sufficient to carry the totai 
 output from the four plants, together with adequate receiving equipment at 
 Calgary. While these estimates are preliminary only, and are for *he purposes 
 of obtaining a comparison of costs and of arriving at the commercial possibilities 
 of the project as a whole, they have been conservatively computed and it is 
 thought they iu\, ample to cover all contingencies based upon present day labour 
 and market conditions. These are summarized in tables Nos. 6 and 7.

 a :'teaiii coal-fired plant and sold on a basis of a 50% load '■ t.<)r, would cost, delive-ed at generator

 Precedents are not wantinK f..r work of the description carried ""^ by the 
 Water Power Branch, either in Canada or in foreign countnes. The most 
 extenaiN^k of this kind in Canada has »-een carried on by the Hydro-Llectnc 
 Commission of Ontario. In the United States 8 mdar work has heen done by 
 sevVral o the states in conjunction with the United States Geologual Survey; 
 Song thosS that should be mentioned, in ''hich work along the hnes of wat.r^

 Minnesota and Washington. 
 
 Ontario. 
 
 In Ontario, the Hydro-Electric Commission has investigated a large num- 
 ber of possible water-powers in various parts of the province and reported upon 
 hen ^^or a number of these, estimates of the cost of development were made 
 in some detail, and are to be found in the reports issued by thenri at yanous 
 "There is a difference, however, between the object of the mvestigaUon 
 made bv the commission and the investigatu.ns here presented; the former 
 were carried on with ihe object of ascertaining what could be done in the way 
 of power production by the commission, whereas the investigations carried on 
 bvTe Wafer Power Branch have been with the ob ect o supplying informa- 
 tion to the public on the subject, and procuring information upon which the 
 best administration of the water-powers could be based. 
 
 New York State. 
 The work of the New York State Conservation Commission, which super- 
 sedes that formerly carried on by the Water Supply Commission, is rather 
 wider n1ts scope tLn that of the Water Power JBranch. The work earned on 
 b the Water Supplv Commission is now under the Division of Inland Waters 
 (f the New York State Conservation Commission; this work is outlined in cheir 
 reports as follows:— 
 
 1. Water storage and conservation for power purposes. 
 
 2. Hydraulic development. 
 
 3. River improvement. 
 
 4. Drainage. 
 
 rt. Water supply and sewerage. 
 
 6 Inspection and supervision of hydraulic structures. 
 It will be seen from the above that the work is very similar in many ways 
 to that of the Water Power Branch in Canada, \\ith rogarcl to the different 
 lites investigated by them, preliminary plans an.l estimates have been pre- 
 pared as has been done in this report. 
 
 State of Maine. 
 The state of Maine Water Storage Commission was established in 190i» 
 under the laws of the state, and consolidated with the state Survey ( ommissiou 
 in 1911. An extract from section 5 of the Act reads as follows:-- 
 
 "The commission shall also report. ..; ' , °" V

 Recommendations. 
 
 In a Iciter published as an ap|K'ndix to this report, Mr. C. H. Mitchell, C.E., 
 consulting engineer on these investigations, has made certain recommendations 
 in regard to the further car'-'-ing out of the work instituted; also as to the 
 operation and control of the \ is proposed; a summary of these recommenda- 
 tions are hei'e given : — 
 
 1 . That the investigations on the Bow river basin be continued for 
 the purpose of making the data more complete and useful in the suDst- 
 (juent operation of the project. 
 
 2. That the Government undertake the further construction of 
 storage reservoirs and regulating works and provide for the repayment 
 of their cost by means of annual rentals charged to users of water. 
 
 3. That a sc-hcme for operating these storage reservoirs and for 
 regulating and controlling the discharge of the river be adopted and put 
 into practical working effect by the Government, and that the annual 
 cost of same be charged to the users in the same manner as the original 
 cost . 
 
 4. That as soon as this project is put into working effect, or sooner, 
 the existing storage works at lake Minnewanka should be acquired and 
 their regulation and operation be taken over by the Government accord- 
 ing to the terms of the existing agreement with the power company.

 mateiial carried down from the surrounding mountains. Below Banff, near 
 Exshaw, the river widens out and covers the greater part of the valley. 
 
 At Kananaskis falls an abrupt change in the topography of the country takes 
 place; this, it may be said, is due to the fact that the river leaves the mountains 
 proper here, and flows out into the foot-hills. These conditions may be said to 
 continue as far as Calgary. 
 
 Divisions of the River. 
 
 For purposes of description, the part of the river lying above Calgary will 
 be divided into two parts, exclusive of the Elbow river, which will be df .It with 
 separately. The upper part of the river lying above Kananaskis falls will b« 
 referred to as the storage section of the river, while that part lying below Kanan- 
 askis falls and as far down as the city of Calgary will be referred to as the power- 
 producing section. 
 
 Power Section of the River. 
 
 From Kananaskis falls nearly to Calgary, the river flows through <:. wide 
 valley for long stretches; the river proper is confined, however, to its channel 
 by steep banks that at diff'erent points are rockv cliffs of considerable height, 
 running as high as from 100 to 150 feet. Generally these cut banks have long 
 sloping banks opposite to them, but in places the river channel is canyon-like 
 for short stretches, lending itself to power development and hence the desig- 
 nation. 
 
 This topography is generally typical of the river, from Kananaskis falls to 
 < "algary. 
 
 Storage Section of the River. 
 
 The storage section of the river, a stretch of approxiniatdv ./O miles in 
 length, lies to the west of Kananaskis falls, and entirely in the mountains. The 
 Bow river rises at an altitude of 6,860 feet above mean sea-level; Bow hike, 
 which is practically its source, lies at an altitude of 6,420 feet, and offers the 
 first and highest site for storage in the Bow basin. About 12 miles below Bow 
 lake, Hector lake, which is at an elevation of 5,700 feet, empties into the Bow. 
 (See reproduction page 14.). 
 
 From Hector lake to a point ne- r Laggan, a distance of 15 miles, the river 
 falls about 650 feet, or about 43 feet per mile. About 2 miles above Laggan, it is 
 joined by Bath creek from the west, and just below Laggan, bv the Pipestone 
 creek from the north. Between the outlet of Hector lake and Bath creek, a 
 number of small streams join the Bow, but on account of the smallness of their 
 discharge during cold weather, they are not worthy of notice. 
 
 Between Laggan and Banff, a distance of 35 miles, the river falls 540 feet, 
 approximately 16 feet per mile. The river valley is very wide in this section, 
 the banks of the river low and the stream swift-flowing; there are no distinct 
 drops, what is practically a continual swift exists between the two points. In 
 this stretch the volume of the river is augmented on the south side by the 
 waters of the Chalet creek, the outflow of Moraine lake, and the waters of Ver- 
 milion, Redearth, and Brewster creeks; there are also many others, which are 
 too small for notice as they have no discharge during the low water or winter 
 season. On the north side there are several creeks of importance— Pipestone, 
 Baker, Johnson, and Fortymile being the largest. All of these creeks are short, 
 and rise at considerable elevations; those entering from the south side commence 
 on the main divide, and have their source, for the most part, in the glaciers to 
 be founu along the summit of the mountair range. (See reproduction 
 page 12.) The creeks entering from the north are longer, and their slopes are 
 not so steep, although their sourres are at considerable elevations, ranging from

 From Banff to Kaniinaskis falls the nature of the topography is not materi- 
 ally changed, except that the mountains are generally lower, the valley is wider 
 and the river more meandering. Between these two points the fall is 380 feet in 
 a distance of 30 miles, about 13 feet per mile, and some of this occurs as a direct 
 fall at the fJpray falls in Banff, at the beginning of the section. Three streams 
 of importance add their waters to those of the Bow in this stretch of river: the 
 Spray, entering from the south at Banff, just below the Spray falls; the Cas- 
 cade, which also forms the outlet of lake Minnewanka, enters from the north, about 
 4 miles below the mouth of the Spray; the Kananaskis, joining the main stream 
 from the south, just above the falls of the same name. 
 
 The important streams contributing their waters to the Bow river will l)e 
 dealt with in greater detail in another part of the rejK)rt, merely their location 
 relative to the main river being given here. 
 
 Lakes of the Storage Sectiov. ^ 
 
 Nearly all the streams flowing into the Bow river have, at or near their 
 source, a lake of greater or less size. Those belonging to the first class arc Bow 
 and Hector lakes, already mentioned; lake Minnewanka, Spray lakes ami Kan- 
 anaskis lakes, the last two forming part of the water system of the same name. 
 Amongst the other lakes belonging to this basin that might be mentioned is 
 lake Louise, its outlet is Chalet creek; this lake is famed for its beauty the 
 world over. Then there are Ptarmigan and Baker lakes at the head-waters of 
 Baker creek, also Redoubt lake oa the same stream; Moraine lake, another 
 lake of great beauty in the valley of the Ten Peaks, which empties into the Bow 
 by way of a steeam of the same name; Boom lake, at the head of Wrmilion 
 creek, and Shadowjake forming one of the sources of Redcarth creek. These 
 lakes tthtgrhe termed storage basins, and have the effect of regulating, t<t :i con- 
 siderable extent, the streams to which they ijclong. 
 
 Stkeam Beds of Stokage Sectiox. 
 
 The mountain streams in this district all have the same characteristic bed. 
 In very few instances does the river How over bare rock, and then only for very 
 short lengths of the stream; generally speaking, this condition is to be met with 
 upon the tributaries and only in places where the stream passes through a can- 
 yon. With these exceptions the river and stream bottoms may be described as 
 being composed of gravel and detritus, which overlies the rocky bed of the 
 streams to a depth of many feet. In some places the bed of the river is in the 
 nature of a large gravel flat where, during the low water period, the river will 
 genera'ly follow a number of small channels; these channels are continually 
 changing; during the high-water period the entire flat may be covered. 
 
 The material forming the river bed is transported from point to point 
 during the high-water periods, and deposited in pockets behind the rocky ridges 
 extending across its path, as bars and shoals. The greater part of the main 
 river channel has Ijeen formed in this way and also the channels of the tribu- 
 taries. In many places the whole valley has become filled for a width of several 
 hundred yards, and on the Bow river these are, in places, of very considerable 
 area. (See reproduction page 14.) 
 
 Underflow. 
 
 The nature of the river beds, formed as they are by gravel and detritus 
 overlying bedrock is very favourable to un(U'rflow. There is no doubt that in 
 these mountain streams, the underflow forms a very considerable portion of the

 natural discharge of the river, but the relation which it hears to the surfat-e flow 
 must necessarily vary, and will depend to a large extent upon the slope of the 
 stream and the depth to which the bedrock is covered by the porous material 
 forming the stream bed.

 During the hinh-water period the umiertiow is rehitively small, but during 
 the low-water period, which corresponds to the winter weaHon, the underflow 
 may be expected to form a very large proportion of the discbarge, and in the 
 smaller streams there is no doubt that at times it forms the total flow. This 
 underflow has a very considerable effect upon the results of gaugings made in 
 the streams, causing results to be obtained which do not truly represent con- 
 ditio s.

 CHAPTER III. 
 ICE. 
 
 One of the problems which confront.^ the eiiKineer in the (iesipn of u water- 
 power development in Canada is the method to be adopted for eliniinafinf? or 
 minimizing the effect of ice upon plant operation and power production. The 
 effect of the ice upon the present plants in operation upon the Bow river is not 
 a direct one; so far no great trouble has been experienced in operating the 
 plant due to ice blocking the water entrances, nevertheless the presence of ice 
 in the river has a marked effect upon the power production, and it cannot be 
 overlooked in the study of any future development. 
 
 Before looking into the effect of ice upon the operation of a plant, it will 
 be well to examine the formation of the ice itself, and bv this means aim at a 
 possible method of dealing with the question. 
 
 There are three kinds of ice which, owing to their effect upon th<' operation 
 of water-power plants, are of interest to the engineer; these arc. -board or 
 sheet ice, " ice and anchor ice. 
 
 .Sheet Ice. 
 
 Sheet ice is that kind of ice which is formed upon the surface of lakes, 
 smooth-flowing rivers, ponds, etc. The process of formation is an interesting 
 one, and begins with the arrival of ct ' \ weather. As the season advances, the 
 water on the surface gives up its L -a" > surface radiation, convection currents 
 are set up, the cold surface water falls and the warmer water below rises; this 
 in turn gives up its heat; by a continuation of this process, the temiwrature 
 of the whole body of water is gradually lowered until it reaches 39° F.; at that 
 temperature convection ceases, and the water on the surface is cooled down 
 until freezing point, 32° F., is reached. The first indication of the fornuition 
 of ice is the presence of long needle-shaped crystals on the surface, these 
 rapidly increase in number and size until finally the whole surface is covered; 
 this surface layer becomes more compact, and the ice increases in thickness, 
 as the underlying water gives up its heat by conduction through the ice; the 
 rate of growth diminishes, however, as the thickness of the sheet increases. 
 
 When the ice sheet is once formed, radiation to a very great extent ceases; 
 this is due to the fact that the ice is seldom clear, and is generallv snow covered 
 and the heat rays are unable to penetrate under such conditions; if the ice was 
 clear and solid, the heat rays could then penetrate, and the loss of heat from 
 the water below would go on at a .uuch more rapid rate, and consequently the 
 growth of ice would be more rapid. 
 
 The presence of any sheet ice in a river immediately above a power plant 
 has a beneficial effect upon its operation rather than the reverse; the reason for 
 this will be understood after the subject of frazil and anchor ice has been dealt 
 with. 
 
 Frazil Ice. 
 
 Frazil ice, known also as "slush ice," is perhaps the ice formation which 
 has the most serious effects upon water-power operations. It is always formed 
 in the open channels where the current is too swift or turbulent to allow the 
 formation of sheet ice, and its formation is dependent upc ilisturbance or 
 
BOW mvr.R POWER as storage 
 
 17 
 
 SESSIONAL PAPER No. 25e 
 
 iiKitution, I'oiisequently swift turbulent streiiins are ^ ■• prolific in its pro- 
 duction; it occurs in needles, the fineness of which are due to the iiniount of 
 nKitation; in such places as rapids, and at the foot of fails, these needles are 
 very fine, hut they increase in size and thickness where the flow is less rapid 
 and disturbed. Frazil ice is always surface formed, but the ice crystals rapidly 
 become distributed throuifhout the whole body of water; this gives rise to the 
 saying that the water is "thick." This condition occurs only durinji a period 
 of extreme cold, combined with great surface agitation, due to rapids in the river, 
 or wind; the direction of the wind relative to the flow of the river has a varying 
 effect on protluction of frazil, a wind blowing upstream produces more frazil 
 than one blowing downstream, on account of increased surface agitation. 
 
 The conditions that make for the greatest production of frazil ice are a 
 dull stormy day, with wind up.stream; a great amount of frazil nuvy be pro- 
 duced upon a clear cold night with wind, but on a clear cold day with wind 
 there is not so great a quantity formed, due to the absorption of heat from the 
 sun's rays at the water surface. Professor H. T. Barnes, in his book on "Ice 
 Formation" says that: (') "A stretch of open water makj's a very much greater 
 quantity of ice in the form of frazil crystals than could be produced as a surface 
 sheet, if the water were sufficiently quiet to allow such to grow." It is this 
 production of frazil which gives rise to so much trouble, the stream becoming 
 l>locked with the mass. Where an ice sheet exists, c(mditions are ofteti 
 aggravated, the frazil blocking the waterway underneath, at times luusing 
 complete stoppage of flow. 
 
 Anchor Ice. 
 
 Anchor ice, "ground ice," the German name "Grundeis" and the French- 
 ("anathan term "moutonne' ' are among the many names given to this particular 
 form of ice. As this list of names would indicate, it has attracted very wide- 
 spread attention, and a number of scientists have published papers iii which 
 its formation has been discussed. The name "anchor ice" perhaps best 
 describes it, and is the one by which it is most widely known in this country. 
 
 The peculiar feature which gives it this name is the fact that it is foriiied 
 upon the bottom of the rivers or streams. Many theories as to the reason of the 
 formation of ice upon the bottom have been advanced. That as set forth in a 
 paper by Rev. Dr. Farquharson, which he published in 1835 and 1S41, and 
 quoted by Dr. Barnes in his work= is generally accepted as the correct one. 
 He attributes the formation of anchor ice to the radiation of heat from the 
 surface of the stream's bed. 
 
 It is remarked that this cooling by radiation, and consequent formation of 
 anchor ice, occurs only in streanis whose beds are composed of gravel, stones 
 and boulders, but not in clay or mud-bottomed streams; also that the formation 
 of the ice is greatest on the rocks and stones of dark colour. 
 
 The formation of anchor ice is most rapid during a clear, cold night i londi- 
 tions which are favourable to rapid radiation). On a clear, cold day, the sun's 
 rays affect the formation; in fact, it is universally noted that on the api)earance 
 of the sun in the morning, the ice becomes loosened from the botton and rises 
 to the surface; its appearance when floating has given rise to the French- 
 Canadian terni; "moutonne," on account of its resemblance to the l)acks of 
 white sheep. 
 
 It has been noted in connection with anchor ice, that its formation does nt)t 
 occur under cover; a liridge <!pinniinK a ■stream retardn radiation atul imvenls 
 Its formation, and it is seldom found where the stream is covered with an ice 
 sheet.

 The nuim'14 frazil und anchor ice are often confused and are frequently used 
 as beinR interchangeable; the term "anchor ice" heing used to designate ice 
 found attached to the bottom, regardless of the method of formation. 
 11 i**™^^*"*'"' Barnes says that:' "In a shallow, smooth-flowing river, we are more 
 likely to have anchor ice formed in excess, whereas in a deep and turbulent stream 
 we are likely to have more frazil. It is hardly likely, however, that there will 
 be a great diflference in the amount of frazil formed in either case; it will probably 
 be that more or less anchor ice will appear in proportion." 
 
 The Montreal Flood Commission in their report deal exhaustively with the 
 question of ice formation. The following is an extract from that report: - 
 
 "The terms 'anchor ice' and 'frazil ice' are indifferently applied to the 
 
 same matenal, but the first evidently is most applicable to this ice when 
 
 found in the bottom of the river. In one respect the two are identical, 
 
 that is, both are exclusively the production of open water. There is no 
 
 formation of either when or where the surface is covered with ice, and 
 
 whereas large formations of both take place in the beginning of winter 
 
 over the vast .surface below Lachine rapids, the further formation of 
 
 this ice ceases as soon, and whenever the ice-bridge is formed. Frazil, 
 
 as distinguished from anchor ice, is formed over the whole unfrozen 
 
 surface above and below Lachine rapids, between Prescott and the 
 
 tide-water and wherever there is a surface current or wind agitation 
 
 to prevent the formation of bordage ice, while anchor or anchored ice, 
 
 except in the shallowest portion> of the current, does not apjjear in 
 
 the deeper water until zero weather sets in." 
 
 In this repf)rt the formation of anchor ice is not ascribed to radiation 
 
 from the nver bottom, but rather to the cooling of its surface through the contact 
 
 with the frazil-charged water. Pniceeding with the description on anchor ice, 
 
 the report says: — 
 
 "On the approach of mild weather, it becomes detached from the 
 bottom, sometimes bringing up with it gravel and stones, and may be 
 seen as a dark-coloured mass bursting up all over the surface with con- 
 siderable force, and with a his.sing sound, which ri;^es a foot or more 
 above the surface, but, falling back, shows only a few inches floating 
 above it. Out of the portion above the surface, the water quicklv drains, 
 and it becomes white as snow." 
 This is the appearance giving rise to tlie term "moutonne" mentioned 
 before. 
 
 In respect to the name "anchor ice" being applied to frazil ice, this is due. 
 in the case of water-power developments, to the action of the frazil under certain 
 conditions. \\ here the head-race of a development is open, allowing the frazil 
 direct acce.xs to the intake without having to pass under an ice sheet, it practically 
 becomes anchor ice, because as it comes in contact with the racks and intake 
 structure it adheres to them and rapidly cuts off the water; under these con- 
 ditions there is no difference between anchor and frazil ice, once the latter has 
 become attached to the structures. As a matter of fact, it is this action of the 
 frazil which causes the trouble directly to plant operations, as it is generally 
 formed m the greatest quantity. The action of the anchor ice proper is to cut 
 off the flow of water in the stream bed; when the anchor ic. is floating the 
 conditions are improving. 
 
 Winter Conditions. 
 
 One condition which requires attention in a study of this kind is the effect 
 of ice upon the discharge of the river, for the formation of frazil and anchor ice 
 '" the bed of these rivers and streams has a very marked influence upon their

 discharge. Lying, as they do, at considerable elevations, the temperature 
 obtaining during the winter months is low and, owing to the steep slope of the 
 streams, their flow is turbulent, thus the necessary conditions are present for the 
 formation of frazil ice. The conditions for the formation of anchor ice are also 
 good, for in many places the stream is too swift to allow an ice sheet to be formed; 
 the water is clear and generally shallow, the nights are cloudless and cold; 
 in consequence anchor ice is formed in great quantities. 
 
 The formation of frazil and anchor ice in the mountain streams causes 
 their discharge to be very fluctuating, and accentuates the variation in flow 
 during the low-water period. 
 
 Winter Conditions as ' KPECTiNti Plant Operation. 
 
 The successful operation of a wait-r plant in winter, on the rivers of ( 'anada, 
 depends in a large measure on the method of providing for or eliminating!: 
 the ice troubles which are always to be met with. 
 
 In the foregoing, the conditions favourable to the formation of the several 
 kinds of ice to be met with have been explained, also the relation of oiu' kind 
 of ice encountered, to another. Of the three principal kinds, sheet or board 
 ice is the least detrimental to operation; in fact if board ice were the only kind 
 to be dealt with, the trouble would be negligible. Where the channels are 
 small, however, and where anchor and frazil have been formed above, great 
 trouble may be experienced, due to the lodging of this frazil and loosened 
 anchor ice, under the sheet, for frazil ice, in the presence of sheet ice, attaches 
 itself to the under side of the latter, and where the channels are small, the whole 
 flow of the stream may become blocked, overflow will then occur ami a great 
 proportion of the stream flow be lost. ( Keproductions pages 1!>, 20, 24 and 2.'>, 
 illustrate the.se conditions.) 
 
 One of the be.st methods, however, of avoiding frazil and anchor ice trouble-i, 
 is by obtaining a iwnd of suflficient .size and depth in the immediate vicinity 
 and above the intake of the plant, which will readily freeze over; the ice sheet 
 obtained will, to a great extent, eliminate any troubles with frazil or anchor ice. 
 
 If the entrance to the power plant is a channel restricted in size, the ice 
 sheet will be a hindrance, rather than a benefit, if there is open water above. 
 In such a case it is much better to be without a sheet of ice, and instead make 
 provision for handling the accumulation of frnzil and anchor ice in the head 
 works. There have been many attempts made to deal with this problem, liui 
 it generally degenerates into a brute force combat. In many plants provision 
 is made for passing masses of frazil ice through the wheels by raising the racks 
 in sections, currents are then induced to pass acr(»ss the face of the racks, "n 
 that the floating ice, etc., may l)e carried off. 
 
 The great trouble with frazil ice is due to its fn-ezing on the racks and the 
 wheels, finally stopping the supply of water. With regard to the rar-ks. thi> 
 has been usually due, in a large measure, to the fact that the up|M>r ends nf the 
 bars composing them have been left protruding above the water for 2 or :i feet 
 exposed to the very cold air: in such a |M)sition these bars become chilled to 
 the bottom, and even when only cooled to two or three one-thousandths of a 
 degree below freezing |M»int, it is sufficient to cau.«e the frazil ice to adiiere to 
 the bars and commence the clogging process. This trouble may be eliinitiati'd 
 to a great extent by making tht upper part of the rack of wood, and keepinn 
 the metal bars entirely submerged, thus preventing the conduction of lie.ii 
 from bars to the atmosphere, and the consequent cooling below freezing point. 
 Besides this method of submerging the metal of the racks, schemes have been 
 brought forward for heating them, such as using hollow bars through which 
 steam may be driven. In many plants instead of this, the head works are housed 
 and heated, not only to provide a good working room for the men fighting tiie

 ice, but also to prevent the subcooling of the racks. One of the most successfu 
 schemes has been that employed by one of the plants in Ottawa; there the 
 tops of the bars are encased with sheeting, steam pipes being also enclosed- by 
 this means ice troubles have been prevented to a great extent. The use of a 
 hve steam jet in the wheel case and guide vanes to prevent the freezing or clog- 
 mg up of the wheel entrance has been quite successful in several plants

 CHAPTER IV 
 
 METEOROLOGICAL PHENOMENA. 
 
 RAINFALL. 
 
 Cenebai.. 
 
 The importance of a study of precipitation in connection with tlie flow of 
 streams cannot be emphasizedtoo mucii; its influence on stream flow is a v«'ry 
 direct one and, without study, the erroneous conclusion is reached that the 
 relation between precipitation and run-off is a simple one. A little time 
 spent in the study of the question soon reveals the fallacy of this assumption, 
 for the relationship is anything but simple, being influenced by a great many 
 physical features of a rather indeterminate nature. 
 
 The collection of precipitation data all over the country has been carried 
 on for a comparatively long term of years, whereas data regarding the run-off 
 of streams are rather meagre; if, therefore, some general relation can be estab- 
 lished between rainfall and run-off, the study of the streams from the stand- 
 point of power production can be placed upon a more satisfactory basis. In 
 the West, and particularly in that part of the eastern slope of the liockies in 
 which we are interested, run-off data have been collected for a very short term 
 of years, and only during the last three has a continuous record of the discharge 
 l)een kept; thus the importance of a general relationship between recorded 
 precipitation and run-off is all the more apparent. 
 
 The distribution of rainfall in any district or part of the country is not 
 uniform. The records throughout Canada, generally, except in the eastern prov- 
 inces, do not extend over a sufficiently long period, nor are the stations widely 
 enough scattered to define areas in which certain amounts of rainfall may be 
 expected. In the West, an examination of the available records seems to indi- 
 cate a general conformation to conditions found to the south, in the United 
 States; that is, that the lines of equal rainfall are generally north and south, 
 or roughly parallel to the mountain ranges; there are of course divergences 
 due to local influences. 
 
 Relation ok Precipitation to Altitude. 
 
 (Jenerally speaking, precipitation decreases with the increase in altitude; 
 it has l)een found in travelling westward away from the .\tlantic that as the 
 country rises, the rainfall decreases. This general rule, however, does not seem 
 to apply to the particular case we are studying, namely, the precipitation in the 
 valley of the Bow river; in fact, the direct opjjosite is apparently the case both 
 here and in practically all the territory forming the eastern slope of the Rockies. 
 An examination of the records will show that as the altitude increases on the east- 
 ern slope, the precipitation increases; special local influences ar'> at work here, 
 however, the mountain ranges in which are situated the sources of the rivers, 
 causing this reversal of the general rule. 
 
 The warm, moisture-laden winds from the Pacific are first intercepted by 
 the mountain."! of the Coast range and deflected upwards to mingle with coid air 
 currents or to come in contact with land at a lower temperature; becoming 
 chilled below the temp<'rature of saturation, they deposit some of the moist i>re

 as snow or rain as they pass over the mountains, giving rise to the heavy pn-- 
 Mpitation near the coast, the greatest recorded on the continent. They theii pass 
 over a stretch of low-lying land, depositing but little moisture until "the Selkirk 
 range is reached, where the process is repeated. When the Rocky mountains 
 are reached the humidity of the air has become much reduced, but the low tem- 
 peratures reached at the higher altitudes is sufficient to cause more precipitation; 
 therefore, in the Bow River basin, with which we are dealing and which is on the 
 eastern slope of the Rockies, it is at the higher altitudes that the greatest pre- 
 cipitation occurs. The alternation of mountain ranges with stretches of country 
 of low altitude is accepted as the cause of the arid and semi-arid regions to l)"e 
 found to the east of the continental divide. 
 
 Value of Records. 
 
 In making a study of rainfall in any district, it should be borne in mind that 
 the average precipitation gives only a relative view of the question, as great 
 variation from the average annual precipitation may occur at different points 
 in the district. In this regard no general law can be made to apply; the number 
 of conditions contributing are so great and variable that, for special purposes, a 
 detailed study of the rainfall in the locality is necessary. 
 
 When studying precipitation records extending over a given period, it is 
 necessary to know what value may be attached to them. Sir Alexander Binnie 
 has given this question careful consideration in a paper published in the pro- 
 ceedings of the Institution of Civil Engineers, vol. 109, pages 89 to 172. He 
 reached the conclusion that for records extending over a period of twentv-five 
 years, the mean obtained would be within 2 per cent of the true mean. ' The 
 conclusions reached bv Mr. Rafter in a discussion of this paper were: that, for 
 a period of five to ten ,( ars, the probable extreme difference from the mean would 
 be 15 per cent, and of ten to fifteen years, 4.75 per cent. Other authorities have 
 expressed the opinion that it is necessary to have records for a period as great 
 as forty years in order that the mean may represent the true mean prpcipitation 
 withm five per cent.

 Accuracy of Records. 
 
 In Canada, the recording stations are all under the direction < ' me Meteoro- 
 logical Service, and a standard method of obtaining the records is adopted. It 
 is to he noted, however, that the placing of the recording instruments can have 
 a very great influence upon the accuracy of the records. To arrive at the average 
 precipitation upon a district, it is necessary that a^ many records as po.ssihle in 
 the area to be considerbd should be available, as conclusions based upon records 
 from a limited number of stations are liable to be considerably in error. An 
 ideal condition under which to study rainfall data would bo "attained if the 
 stations were uniformly distributed over the territory, or placed along each 
 branch of the stream of which the relation between run-off and precipitation 
 was to be established.

 A study of the periodical distribution of the rainfall is intercstii . Cciicr- 
 ally tliis distribution throughout the year, fiom vcar to vcar, is fairly constant 
 in any ihstrict. but is cHfterent in different districts; fi.r instance, there is a 
 similarity in the distributitm in the different localities along the PacKic coa.st • 
 the .same may be said of the territory to the east of the Hockies, while that 
 portion around the Creat Lakes has its typical distril)utioii. 
 
 Two tables .showing the fluctuation intiie annual precipitation recorded at 
 HantT and Calgary have been prepared, and appear at the end of the reiM.rt 
 At Hanff, the records are ava. able at intervals from 181K) to 18<H>, from which 
 year the> are contmuous to date; during that perioil, the maximum |)recipitation 
 occurred in 1902, 30.59 inches Iwing recorded, and the minimum was l().8:i 
 inriesin 1903; the mean yearly precipitation for twenty years is 19.13inches. At 
 ( aigary, the records are available from 188.5 to date' during which interval 
 the lowest recorded annual precipitation occurred in 1892, 7.91 inches being the

 amount; and in 1902, the maximum precipitation occurrred, 34.57 inches being 
 recorded; the mean yearly precipitation over the period of twenty-seven years is 
 lb. 10 mches. 
 
 Owing to the scattered location of the recording stations in the district 
 
 at Banff, Calgary, and Jumping Pound (from the latter, only partial records are 
 available)— they do not truly represent the conditions obtaining in the basin. 
 
 As has been mentioned before, the precipitation increases in this locality 
 with the altitude; the altitude of the station at Calgary is approximatelv 
 3,400, that at Jumping Pound about 4,200, and at Banff 4,525 feet, and an 
 exainination of the records will show a greater precipitation at Banff and Jump- 
 ing Pound than at Calgary, that recorded at Banff being the heaviest of the 
 three. The sources of the Bow river and its tributaries are at much greater 
 altitude than is the gauging station at Banff; in fact the greater part of the 
 drainage area above Kananaskis falls lies above this altitude, so that the stations 
 are by no means representative of the greater part of the drainage basin. 
 
 Relation of Precipitation to Runoff. 
 
 If the records of precipitation are compared with those of the run-off on 
 the »^asin, it will be found that the recorded run-off exceeds the precipitation as 
 recorded at Banff, by as much as 25 per cent. This condition is by no means 
 uncommon for mountai-. districts. Mr John R. Freeman, in his report on the 
 Hetch Hetchy Water Supply for San Francisco, says:— 
 
 "In regard to the excess of run-off over precipitation, the fact that 
 depth of run-off exceeded depth of rainfall at outlet simply proves that 
 the average precipitation for the catchment as a whole was far greater 
 than at this comparatively sheltered spot of lower altitude at the outlet 
 of the valley. 
 
 This condition holds in the Bow basin, and emphasizes the need of more 
 stations for the recording of precipitation. 
 
 On account of the short period over which complete run-off data are avail- 
 able, and the few precipitation recording stations in the catchment area, no 
 defimte relation can be established between run-off and precipitation. The 
 only conclusion that can be arrived at from a study of these data is that for the 
 water years from 1909 to 1911, the mean precipitation has been neariy equal to 
 the mean vearly precipitation for the last sixteen years, as recorded at Banff. 
 It IS fair, therefore, to assume that the run-off during the same years represent 
 approximately the mean run-off conditions during a like period. 
 
 Division of the Year. 
 
 In considering the relation of precipitation to run-off, a period known as a 
 water year is made use of, instead of the calendar year. This period for the 
 Bow Basm district may be assumed as extending from October 1 until Sentember 
 JO, for practically all of the water is obtained from the mountains, and from 
 October 1 on, the precipitation in the form of snow is stored in the mountains 
 to be held until the warm sun of the following oarlv summer releases it. to form 
 the summer freshets which occur during May, June and July. 
 
 TEMPKRATURE. 
 
 . a Tfn'Pt'rature in the Bow river drainage area is one of the great factors 
 influencing the discharge of the river; in the upper part of the catchment area 
 there is not a month in the year in which frost cannot be expected. The range 
 of temperature is great, the range of mean temperatuie at Banff (see tables) is

 from 56". 9 in July to 13°. 7 in January, or 43°. 2 of difference; at Calgary, the 
 range of mean temperature is from 70° . 7 in July to 14° . 2 in January, or a range 
 of 66°. 4; and the maximum and minimum temperature greatly exceed these. 
 From these two records it will be seen that the one at the higher altitude registered 
 the lowest temperature. At the higher altitudes it is to be expected that low 
 temperatures will be encountered, and that the period during which conditions 
 of low temperature obtain will be longer than at the lower levels. The records 
 are taken at an altitude which is low, considering the drainage area of the Bow 
 river as a whole, and hence do not represent truly conditions in the upper 
 part of the valley of that river; they give, however, an indication of the con- 
 ditions to be found and, upon study, reveal some interesting facts with regard 
 to the bearing of temperature upon the discharge of the river. 
 
 Influence upon Evaporation. 
 
 The influence of temperature upon evaporation is one which is constant 
 and unmistakable, but is one for which, so far, no relation has been established. 
 HufBcient data are not available for a study of the question in the district, but 
 in passing it seems well to note the work that has been done in this regard, 
 and which is well summed up in a paper by Mr. Rafter, published by the United 
 States Geological Survey. In this paper Mr. Rafter had made a careful analysis 
 of the available data, and he reached the conclusion that no definite relation 
 exists between evaporation and temperature, but that the influence is a constant 
 one, and cannot be disregarded. 
 
 iNFiiUENCE or Temperature on Discharge. 
 
 There is no other single cimdition which plays such a vital part, or has 
 such a direct influence upon the discharge of the rivers of the district a.s 
 temperature. A diagram, Plate No. 2, has »>oen prepared, showing graphically 
 this relationship — the daily discharges of tue Bow river at Banff have been 
 plott«d continuously, and on top of this has been plotted the mean daily 
 t«mperature as recorded at Banff from April, 1910, to December 1912. .\ .other 
 diagram, Plate No. 3, has been prepared for the period Noveiiil)er 6, 1912, to 
 March 6, 1913, showing the mean daily discharge for the Bow river at Horse- 
 shoe fulls, and the mean daily temperature as recorded at Banff 
 
 A study of these diagrams will reveal how direct is the influence of tempera- 
 ture upon the discharge of the river; during months of low tempi-rature the 
 <liHcharge is shown to be low. On the other hand, high temperature corres|)onds 
 to large discharge, although within the limits of the record, the highest tempera- 
 tures occur in the month ifoUowing the highest discharge; this can In- explained 
 by the fact that, except upon the mountains permanently covered, the snow 
 has nearly ail been melted during June and the early part of July. 
 
 The second diagram, Plate No. 3, shows clearly that the influence of low 
 temperature on the discharge is unmistakable. The period selected is that 
 covering the low-water stage of the river, which corresponds to the perio<l 
 during which extreme low temperatures are encountered throughout the 
 interval covered, by the curve. It will be noted that the mean temiwrature is 
 nlwve fr(>(>iing on only eighteen days, consequently it affects not only the source 
 of the river but also the actual flow in the river its<'lf.

 RUN-OFF. 
 
 GENERAL. 
 
 All rivers having their source on the eastern slope of the Rocky mountains 
 have a characteristic flow quite different from that of the rivers of Eastern 
 ( "anada. Generally speaking, in the latter streams the low-water conditions 
 i-xist during the summer months, normal flow occurring throughout the winter 
 months, and high water during the spring. This condition is reversed in the case 
 of the mountam streams. The low-water stage of the rivers extends over the 
 winter months; the flood stage is reached during the early summer, then 
 gradually subsides, the normal stage being reached in the late summer and 
 early fall. 
 
 These conditions are typical of the mountain streams, and the Bow river 
 and Its tributaries are no exception to the general rule. For the section above 
 ( algarj-, a hydrograph has been prepared, showing conditions at Horseshoe 
 falls, and it may be considered as typical of the discharge conditions in regard 
 to armual distribution of flow, at any point in the section. (See plate No 1) 
 
 The division of the year according to the calendar does not correspond 
 with the regulation of the nver's flow, and it has been found advantageous there- 
 tore to make use of a division of the year corresponding to this annual cycle- 
 this division has been called the "water year." 
 
 The water year in the district of which the Bow valley forms a part, extends 
 trom October 1 to September 30; it is of course an arbitrary division, but it 
 approxunates very closely to the different stages of the rivers, beginning with 
 the low-water period. The river derives the greater part of its water from the 
 mountains; roughly speaking, after the first of October, all precipitation of 
 moisture in the mountains is in the form of snow, and remains in that condition 
 until melted by the warm sun during the following summer. 
 
 The fluctuation of flow of the river during the eariv part of the fall and 
 wint«r months, say from September 1 until November l, is dependent almost 
 entirely on the rainfall in the lower part of the drainage basin. (See hydro- 
 graph of Bow River, Plate No. 1.) During these months the flow is gradually 
 (liminishmg, due to the storage of precipitation in the form of snow and ice in 
 the higher altitudes. From December 1 until April 1 may be called the low- 
 xvater penod; the river during this period is dependent almost entirely upon 
 the discharge of ground water, springs, and other underground sources. Ex- 
 treme lo\v water may be expected to occur during January and Februarv; after 
 the end of tebruary the flow is augmented by the melting of snow in the lower 
 parts of the va leys, and the discharge is increased gradually throughout March 
 and Apnl and by May 16 the first of the floods generally appear; the discharge 
 <lunng May rapidly increases. In the month of June the rainfall is heavy 
 this, coupled with the molting snows of the mountains, produces a condition 
 lavourablc to large run-off, and it is on this account that the mean monthly 
 liischarge is generally largest for that month. 
 
 The rainfall in July is also large, but the amount of snow in the mountains 
 has l)eon greatly depleted, so that the mean discharge is generallv lower than 
 for June; very high water may occur, however, during the month of Julv; in

 fact, two of the highest floods on record in the Bow river have been recorded 
 in that month, but the mean discharge for the month is, as a rule, lower than 
 for June. 
 
 In the month of August, normal stage of the river is reached, and this con- 
 tinues through September, completing the "water-year." The rainfall during 
 August is frequently heavy, and no doubt has the effect of increasing the dis- 
 charge of the river very materially. 
 
 Underground Flow. 
 
 The underground flow in all streams of which the beds are composed of 
 gravel, detritus and similar loose material, must he considered when es^timates 
 of run-off or discharge are being made. The indicated surface flow of the river, 
 where the above conditions exist, is not an evidence of the true discharge. The 
 discrepancy between the true flow and the surface flow may be large, while on 
 the other hand the underflow may form but a small part of the total flow of 
 the river. 
 
 The character of the stream bottom is one of the chief influences govern- 
 ing underflow. If the material is composed of gravel, or disintegrated rock, 
 such as is to be found in the mountain stream^, and where there is little material 
 of a finer nature to fill the interstices, the percentage of voids will be high 
 and the amount of water passing through will be large, resistance to flow being 
 small. If, on the other hand, the bed is composed of the gravel, etc., mixed with 
 sand, the spaces will be small, the resistance to flow will be increased, and in 
 consequence the amount of underflow will form but a very small proportion of 
 the total flow. 
 
 The question oi slope of the bed of a stream is also an influencing element. 
 Where the bed of a stream is comparatively flat, the amount of the total flow, 
 existing as underflow, will be large, as penetration to a considerable depth in 
 the underlying material may be expected. Where the slope is steep, this pene- 
 tration is necessarily shallow, and in consequence the underflow is smaller. 
 
 There are a number of streams in the Bow River basin where this feature 
 of underflow is remarked, and perhaps th'> best example of this is on the Ghost 
 river, though no attempt has been made to arrive at any conclusion as to the 
 volume of underiiow in any ca 3. 
 
 The Ghost river owes its name to the fact that at certain points in its course 
 the complete flow of the river disappears. 
 
 From a point well up in the mountains the valley of the Ghost river is, for 
 the greater part of its length, very heavily covered with gravel. (See repro- 
 duction, page 14.) In many places the valley is quite wide, and during 
 low water the stream is split up into a number of small rivulets, each follo\\ing 
 its own course across these wide flats; where the gravel is deep, the total low 
 flow of the river disappears in the gravel, to reappear farther downstream. 
 
 Another example of underflow in the district is found uix)n the Elbow. 
 On this river it has been noted through the coniparist)u of practically simul- 
 taneous gaugings, that there was apparently l.'ss water flowing at one point 
 than was recorded at another higher upstream. Such conditions have been 
 noted in other places, but no attempt has been made to arrive at the magnitude 
 of the underflow at any point. 
 
 The existence of this underflow means that there is a flow available for 
 power production larger than gaugings would lead one to expect. The placing 
 of a structure in the stream-bed has the effect of intercepting this sub-surface 
 flow and causing it also to pa-ns thrtnigh the structures. It also has an important 
 bearing upon the consideration of the relative discharge of difl'erent tributaricM, 
 and so should not 1h« ignored in any scheme of regulation, or in the study of 
 any hydrographs prepared from current meterings.

 Low-Watek Discharge. 
 
 u 
 
 In the winter months the stream flow is low, and during the period Decem- 
 ber 15 to March 1, the extreme condition is reached. Just how extreme this 
 condition is may be realized by a study of the following figures: The maxi- 
 mum flood discharge recorded at Horseshoe falls during the period 1910-1911 
 was on July 24. 1911, when a flow of 14,770 c.f.s. was noted; on January 24, 
 the same year, a minimum dischi'-ge of 590 c.f.s. was recorded; for the water- 
 year 1910-11, the mean daily discharge for the period January 1 to May 1 was 
 851 c.f.s.; for the period October 1 to January 1 the mean tiaily flow was 1,983 
 c.f.s. During the remainder ol the water-year, the flow was high. 
 
 In the above year the discharge during the latter part of December was 
 high, the highest daily flow being December 31, when a discharge of 1,904 c.f.s., 
 was noted; on the first of January, an abrupt change took place, the discharge 
 being under 900 c.f.s., so that the periods for which the mean discharge are 
 given are fairly chosen. 
 
 Flood Dischabge. 
 
 The discharge of a river during flood period, is a factor in any study of 
 power development and is of prime importance. As soon as the design of a struc- 
 ture to be placed in a water course is taken up, the question arises as to what 
 volume of water it may be called upon to discharge under flood conditions, and 
 the best method of safely taking care of the flow at such a time. 
 
 Mountain streams are noted for the great difference between their normal 
 and their flood discharge; instances are on record where the ratio between max- 
 imum and minimum flow is as high as 1 to 40, and 1 ♦o 50. The Bow river 
 belongs to this class of streams; it is on record that the flood discharge at Cal- 
 gary has been as high as 54,000 c.f.s. (in the flood of 1897), while the low-water 
 discharge is known to be, at times, less than 1,000 c.f.s. at the same point. 
 
 In an interesting report, Mr. P. M. Sauder, Chief Hydrographer of the 
 Irrigation Branch, discusses the floods on the Bow river, and estimates the 
 flood discharge in round numbers at 60,000 c.f.s. ; ho also speaks of several other 
 floods which have occurred; one in the early part of July, 1902, that followed a 
 period of heavy rains, was very destructive, but it is estimated did not reach the 
 discharge of that of 1897. 
 
 Several flood" which have occurred are mentioned in Mr. Saudcr's report, 
 one in 1879 is stated to have been the largest of which there is any record, and 
 another in 1884, evidence of which places it as 1 foot lower than the flood of 
 1897; all these floods occurred before any systematic record was kept of run-off 
 data relating to the Bow. Since 1908, almost continuous records have been kept 
 of the run-off, with the exception of the winter months cf the first few years; 
 in that time, only two floods of any note have occurred, one in July, 1909, when 
 a discharge of 23,000 c.f.s. was recorded, and another in July, 1912, which is 
 supposed to exceed that of 1909, but for which there are no figures available 
 
 In the same report an estimate has been made of the probable flood dis- 
 charge for different reaches of the river; they are as follows: From Kananaskis 
 falls to Ghost river, 40,000 c.f.s.; from the Ghost river to the mouth of thr 
 Jumping Pound creek, 50,000 c.f.s.; between the Jumping Pound and the 
 mouth of the Elbow i . or, 60,000 c.f.s. ; and below the mouth of the Elbow river, 
 70,000 c.f.s. This discharge, it will be interesting to note, averages about 19 
 c.f.s. per square mile of drainat;e area, or a precipitation of seven-tenths of an 
 inch per twenty-four hours. 
 
 Winter Co.n'ditions. 
 
 The factor which governs in any hydro-electric development, is the discharge 
 of the river during the low-water period; in this district the low-water period 
 occurs during the winter months; therefore, investigation of the winter conditions 
 is of prime importuncc.

 SESSIONAL PAPER No. 25e 
 
 In a previous chapter, the question of temperature was dealt witli, in its 
 relation to run-oflf, and it was there shown that a direct relation exists between 
 the two, especially during the winter months. A brief reference to Plates 2 and 
 3 is again necessary; it will be seen that a low discharge occurs simultaneous with, 
 or immediately after, a \o\f temperature, and that a high discharge occurs 
 approximately at the time of high temperature. In studying Plate 3 it 
 should be borne in mind that some discrepancy is due to the effect of storage on 
 the natural How of the river, but the close relationship between discharge 
 and temperature is apparent. The inference drawn from this fact is that the 
 decrease in discharge at times of low temperature is due to the effect of the cold 
 weather upon the flow in the immediate section of the river studied, and not 
 upon the source of the river. , • i . 
 
 The winter flow of the river is also dependent upon other sources which do 
 not show the immediate effect of temperature, the decrease in flow being gradual. 
 
 Stream Measurement. 
 
 The measurement of the flow of the Bow river, and streams in the vicinity, 
 has been carried on more or less regularly for some years; gaugings were made 
 as early as 1894, but no continuous records were kept until 1908. From 1908 
 until 1911, the records are only available for what might be termed the open- 
 water season, while during this period the records are sometimes available as 
 late as the end of December of each year, the flow during Januarj-, February. 
 March, and in some cases the early part of April, was not recorded ; this particular 
 interval, during which the low-water flow occurs, is the vital period from a power 
 standpoint. This work has been carried on by the Hydrographic Survey of the 
 Irrigation Branch. 
 
 In the early part of 1911, the work embodied in this report was instituted, 
 and, at the beginning of the same year, the collection of records covering the 
 low-water stage of the river was commenced on the Bow river and three of its 
 tributaries. In order that a complete set of records might be available in the 
 district, an arrangement was made between the Irrigation Branch and the 
 Water Power Branch, whereby additional stations were established at points 
 suggested by Mr. C. H. Mitchell, the expense being borne by the Water Power 
 Branch, and the work of establishing and operating done by the Irrigation 
 Branch; the stations established under this arrangement were; Ghost river, 
 Kananaskis river, Pipestone creek, Bow river at Laggan, and Cascade river. 
 
 From a power standpoint, the need of continuous records of run-off in these 
 streams, especially the low-water flow, is very pressing. Almost as oft n as 
 estimates of the low-water flow are made by parties interested in power deve- 
 lopment, it is found, when records are subsetjuently made available, that the 
 flow has been overestimated, frequently as much as 100 per cent. This is no 
 doubt partly due to the rivers being investigated in the summer months, when the 
 flow is high, or above the normal; ii condition which is quite the opposite to that 
 found in some other localities at the same period; this, together with the lack 
 of data, is no doubt the cause of errors in estimate. 
 
 Discharge Data. 
 
 Included as an Appendix are tables giving the daily discharge of tlie Bow 
 river at different points in its course; also similar tables for the different tributaries 
 above Calgary, and including the Elbow river; these tables are compiled from 
 information placed at the disposal o( the Water Power Branch by the Irrigation 
 Branch. In connection with this information, where gaps occur in the records, 
 they are filled out with infonuation obtained from the records of the Calgary 
 Power Company; this refers particularly to the discharge of the Bow river

 CHAPTER VI. 
 
 EXISTING DEVELOPMENTS. 
 
 EAU CLAIRE PLANT. 
 
 The first hydro-electric development on the Bow river, in the section from 
 Calgary west, is that of the Eau Claire Lumber Company, situated within the 
 city limits of Calgary. The development makes use of the natural fall in the 
 river, by mean." of a diverting dam (pile and timber construction) and a canal, 
 and the head developed is in the neighbourhood of 12 feet. The diverting dam 
 is situated just above the bridge crossing the Bow river at Ninth Street West, 
 and the intake and canal are on the south side, the canal following the south 
 bank for about one-half mile. Advantage is taken of small islands or gravil 
 bars, and these, together with timber pile structure, form the stream side 
 of the canal. At the lower end, an island forms the north side of the canal or 
 forebay, the original channel between it and the mainland forming the tail-race. 
 Leffel wheels, set in an open timber wheel case, spanning the channel, are geared 
 to two jack shafts, bolted to two generators. The installation is for 600 horse- 
 power. 
 
 The head developed is about 12 feet, the total flow of the river at low water 
 being utilized. The agreement between the company and the old Territorial 
 Government, later approved by Act of Parliament, gives the company the 
 right to the total low flow of the river at that point, and an amount equal to 
 the low flow at high and normal stages of the river. 
 
 The development is not on a very permanent basis, and cannot be a very 
 efficient one, though with such a small head, and the restricted flow of the river 
 that exists, the expenditure of not very large sums of money upon its development 
 would be wtarranted. 
 
 Thi8 plant supplies power for lighting throughout the city of Cal(pary, 
 having a franchise for the ("'itribution of power. The water-power is assisted 
 by steam generated power, and in consequence the service is liable to very few 
 interruptions, but it is understood that during the winter season the operation 
 of the water-power plant is interrupted for considerable periods, owing to ice 
 troubles. 
 
 LAKE LOUISE POWER PLANT. 
 
 General. 
 
 This plant while very small, and scarcely to be considered from a com- 
 mercial standpoint, is mentioned for two reasons: first, because it lies within th<< 
 territory studied; and second, because it is operated in ronnection with tho 
 Canadian Pacific Railway hotel at lake Louise. 
 
 Dbvelopuent. 
 
 The power station is situated about half a mile from the chalet. Tlie water 
 is conveyed from lake Louise by means of a pipeline about 2,800 feet long to 
 the power station, which is situated on Chalet creek, the outlet of the lake; 
 and which also forms the tail-race.

 Intake. 
 
 A bridge leading across the outlet of the lake is so designed as to form a 
 <lam and overflow for the lake, and also part of intake structure. 
 
 Pipeline and Head. 
 
 . The pipeline which conveys the water to the plant is a wood stave pipe 
 20 mehes in diameter and approximately 2,800 feet long. It is laid on th«> ci^t 
 side of the creek for the greater part of the distance, and the gross head devolowd 
 IS approximat^'ly 140 feet. ' 
 
 Equipment. 
 
 The pipeline leads to a 24 inch S. Morgan Smith whe«>l which runs at 600 
 r.p.m. The wheel is rated at 100 horse-power, and is belted to a 7.5 k.w 3-nhase 
 genenitor which operates at 1,200 r.p.m. and has an ex.-iter mounted on the 
 shaft. Thecurrrnt is transmitted to the chalet at 2,r,00 volts where it is 
 stepped down tr 125 volts for lighting and other uses.

 Intake. 
 
 The intake structure is distinct from the dam and occupies a position 
 adjacent to it, approximately parallel to the stream flow. The water, which 
 is admitted through racks and concrete chambers to the penstocks, is con- 
 trolled by means of stoplogs and butterfly valves placed in the inlet chambers. 
 
 Penstocks. 
 
 Provision has been made for four penstocks; three of these have been 
 built and one is now under construction. These penstocks are of two sizes; 
 the small ones, 9 feet 6 inches in diameter, and the larger, 12 feet, each deliver- 
 ing water to a single unit. The penstocks are approximately 250 feet in length, 
 supported upon concrete piers, and protected from possible interference from 
 the river at the lower end by a concrete wall. On account of the severity of the 
 climate, it was considered necessary to house the penstocks, and a frame 
 structure was built, inclosing them for their full length. 
 
 Power Station. 
 
 The power-house (see reproduction page 35), the main part of which 
 measures 118 feet by 56 feet, is situated in the gorge below the dam; it is of 
 steel, concrete and' brick construction, and houses the turbines, generators, 
 exciters, etc. At the back of the power house, and partly oyer the penstocks, 
 the switch and transformer rooms are built. The tail-race is protected from 
 back water in time of flood by means of a wing wall, which separates the 
 tail-race from the river for some distance below the power-house. 
 
 Equipment. 
 
 The complete turbine installation consists of four turbines of the hori- 
 zontal double-ruaner type in steel wheel cases, and two exciter turbines of the 
 single-runner type, the latter being of 330 horse-power capacity each. Two of 
 the main units are of 3,750 horse-power capacity and, with the governors, were 
 supplied by the Jens Orten-Boving Company; they are of Swedish manufac- 
 ture, as are also those of the exciter sets. The other two main units are of 6,000 
 horse-power each, built by Wellman Seaver Morgan Company, of Cleveland, 
 Ohio, and are controlled by Lombard governors. The smaller units are direct- 
 ly connected to two generators, of 2,500 k.v.a. capacity, being 3 phaw, 60 
 cycles, 300 r.p.m. machines and operating at 12,000 volts. The other two units, 
 one of which is now installed, are direct-connected to generators of 4,000 k.v.a. 
 capacity, operated at 12,000 volts, 3 phase and 60 cycles. The generators of 
 the exciter sets are 175 k.w., 125 volt, and 700 r.p.m. machines. The generators 
 were built and supplied by the Canadian General Electric. 
 
 The current is carried from the machines to two busses, one supplying thf 
 lines to Exshaw at 12,000 volts, the other supplying the step-uj) transformer 
 which raises the voltage to 55,000 for the Calgary lines. 
 
 The transformer room contains two 3,000 k.v.a. 12,000 to 55,000 volt, 
 oil-insulated, water-cooled, 3-pha8e transformers, and two more of the sanir 
 capacity will he installed very shortly. 
 
 Transmission Lines and Substations. 
 
 The company has three transmission lines in operation, one exlendiuK to 
 Exshaw, a distance of 8 miles, and the others forming a duplicate line to Cal- 
 gary.

 The Exshaw line supplies power to the cement plant at that place; it is a. 
 double circuit, 3 phase, 12,000 volt line, strung on wooden poles, the conduc- 
 tors being of six 00 aluminum stranded cable; in connection with the hne there 
 is a telephone line strung upon the same poles, and also a ground wire. The 
 transformer station at Exshaw contains four 700 k.v.a. 12,000-600 volt, oil-in- 
 sulated, water-cooled transformers, with lightning arresters and switching 
 apparatus complete. The switch apparatus in this station was installed by the 
 Canadian General Electric Company, and the transformers by the General 
 Electric Company of Sweden. • i • * 
 
 The transmission line to Calgary is in duphcate; each is a single circuit 
 3 phase 55,000 volt line, the conductors being No. aluminum, with telephone 
 line and ground wire carried on 40 foot wooden poles. The lines are parallel 
 to one another for the first lOH miles from the power-house, and follow the 
 Canadian Pacific railway; they then separate, line No. 1 turns southwest and 
 leaves the Indian reserve, just to the east of the old south road to Morley, and 
 joins the road outside the reserve; from that point it follows the road allowance 
 to the city of Calgary, following the Springbank road to within 8 miles of the 
 city the total distance is nearly 51 miles from the power-house to the sub- 
 station in Calgary. The second line from the point where line No. 1 turns 
 southeast, runs straight to the northeast corner of township 25, range 6, west 
 of the 5th meridian; it follows the north boundary of township 25, ranges o, 
 4, 3, and 2 to the northeast corner of section 35 in township 25, range 2, except 
 for a slight jog near Cochrane, where a diversion is made to avoid a line cross- 
 ing- at the point mentioned it turns south and joins the other line at the south- 
 east comer of section 1 township 24, range 2, and from there to the substation 
 it parallels the other line. This line crosses the Bow at two points; first, just 
 west of Cochrane, and the second time at Shaganappi. 
 
 These lines will handle the power output of both the plant at Horseshoe 
 falls and that at Kananaskis falls now being built. 
 
 The Calgary substation, the capacity of which is shor ly to be increased, 
 provides for delivering power to the city and the Canada Cement Company, at 
 three voltages, 12,000, 2,400 and 600 volts. This is accomplished by means of 
 3,000 k.v.a., and 1250 k.v.a., oil-insulated, water-cooled, 3 phase transformers 
 with the necessary switch apparatus. 
 
 The transformers and switch apparatus were manufactured and installtMi 
 by the Canadian Westinghouse Company. 
 
 Construction. 
 
 The design and construction of the plant was carried out by the engineer- 
 ing firm of Smith, Kerry & Chace. The dam presented some interesting prob- 
 lems which required considerable thought and care in solving. 
 
 In order that the site of the foundation might be unwatered, and the dis- 
 charge provided for during construction, two unwatering tunnels were driven 
 on the intake side of the river, from the under side of the lip of the falls up to 
 the upper level, and at such an elevation that only a low coffer-dam was neces- 
 sary to keep the water out of the foundation of the dam. The rock outcrop 
 which forms ttip fall, and upon which the dam was constructed, dips across the 
 river at a considerable angle, (see reproduction page 35) and upon uii- 
 wiitcriiig and exploration of the lower part (the section near the north bank) it 
 was found that the material which is illustrated in the section shown on the plan 
 of the development was not of a satisfactory nature for foundation purposes; 
 an examination proved that no better material underlay it, and this material 
 necessitated special treatment. While the section containing the sluice-ways 
 was being built, Mr. John R. Freeman was called in by the company t- "(Ivisc 
 in the matter; his report of October 10, 1910, accompanieil by plan? -ving

 layout and proposed changes, was acted upon, and the plans of the plant as 
 l)Uilt, included here, embody the recommendations made. 
 
 Precaution in Construction. 
 
 ThefoUowing precautions were taken, based upon the aforementioned report • 
 1 The hard sandstone ledge, upon which the dam was to have been built' 
 dipped at such a considerable angle that the cost of carrying the foundations 
 down to this rock throughout the length of the dam, would have been excessive 
 ihe northern part of the dam was therefore built upon the shaly rock over- 
 lying the hard sandstone, which it was considered would afforil a safe foundu- 
 
 In order to obviate any leakage that might develop through the under- 
 ying seanis, 3-inch holes were drilled through the rock, about 2 feet in front of 
 the face of the dam, 10 feet apart, and to a depth of about 40 feet; a casinu was 
 then p aced m the upper part of the hole, and a thin cement grout forced into 
 the ho es unde- a pressure varying between 60 and 80 pound." per .square incli 
 until they refused to hold any more. By this means the grout would be forced 
 into any seams in the rock, cross cut by the holes, ami for a considerable dis- 
 tance from the holes, by hrst filHng alternate holes and later filling the remain- 
 der, It was expected that all the seams would be completely filled for some dis- 
 tance from the line of holes. That considerable grout was ab.^orbed bv the 
 «eams IS shown by the diagram, which shows the amount of cement grout placed 
 in each hole, and the amount necessary to fill the hole itself. (See diaEr-im 
 riate r^o. o.) ^ n > 
 
 2. The possibility of leakage around the north end of the dam wa.s met bv 
 excavating a cons^idcrable distance into the cliff, for the total height of the dam; 
 t M clift conshsts of a soft shale, liable to disintegration on exposure to air but is 
 the excavations were completely filled with concrete, any water leaking through 
 the seams in the shale would be forced to travel a considerable distance, and the 
 (luantity would be great y reduced by friction, and as the seams are liable to 
 silting, the leakage would be very nearly eliminated. 
 
 3. The inspection tunnel, before mentioned, also serves the purpose of a 
 drainage tunnel. Drainage holes, about 10 inches square, and placed 16 feet 
 8 inches apart, extend from the springing line of the arch of the tunnel upward 
 through the body of the dam, so that any leaks that mav develop through 
 •TOcks will be intercepted and directed into the drainage tunnel. Other holes 
 3 inches in diameter, and about 12 feet (i inches apart, have been drille.i ,lown 
 through tlu' base of the dam into the utul^Tlying rock for depths of from 10 feet 
 to 18 feet; these are cased at their upi.er end, in order that the quantitv of anv 
 water leaking through them and also the upward pressure may b.- measured

 ;>. Ihe protection of the foundation of the dam at tiie downstream si,l,« has 
 required careful consideration. In order that erosion due to the water comine

 he apron of tlie dam be extended downstream about 40 fwt, heavilv rein- 
 forced and anchored to the rock, and that baffle piers be built on the apron to 
 HHiuce the velocity of the water and thereby prevent any possible erosion Other 
 recommendations were made, one was the building of a baffle wall on th.' crest 
 of the old falls at the south end of the dam, ami the facing of tin- diff below to 
 F)revent undermining, but these recommendations, together with that of placing 
 of a sand blanket over the bed of the river, have not vet been .•.i-ried out

 Inspection and Approval. 
 
 In a foregoing part of this report^ the policy of tlie Water Power Braneh in 
 regard to the approval and inspection of any water-power development htv* l)een 
 set out. This policy in the case of Horseshoe falls, has, with the exception of 
 the appointment of a re.sident engineer, been carried out; Mr. John R. Freeman 
 was conHultcd by the company with regard to the plans, and Mr. C. H. Mitchell, 
 CK., as consulting engineer on the Bow river work, made several inspections 
 of the plant both during the latter part of construction, and after completion, 
 and \m> submitted two reports to the braneh covering the work. 
 
 KANANASKLS FALLS PLANT. 
 General. 
 
 The Kiinanaskis Falls plant i.« placed under the heading of plants in exist- 
 ' iiit<, though at the present writing it is only in the course of construction. 
 
 Site. 
 
 The ."itc of the Kananaskis Falls plant is at the falls of that name on the 
 Mow river. These are about 2 miles upstream from the Horseshoe Falls plant, 
 and immediately below the junction of the Bow and Kananaskis rivers; in fact the 
 l;itt<'r stream, entering from the south, adds its waters within the limit of the 
 rapids at tin- head of the falls. 
 
 The total fall at thi^ point occurs in four sections; first, the rapids just 
 nil ntioned, and then a series of three falls, giving a total drop of approximately 
 ■>."> feet. Above the rapids the Bow river is wide and fairly shallow (see repro- 
 tliii I'.Mi page 40), the banks are comparatively low, gradually increasing 
 in htiirht to the head of tha falls. Below the falls, the bank.? are perpendicular. 
 till- river flowing through a rather wide canyon. Tha banks of the Kananaskis 
 .ire liigh; the west bank is perpendicular, rising at least 40 feet above 
 the surface of the stream; the slope of the east bank is more gradual for the 
 first few hundred yards, but after that it is high and abrupt. 
 
 The Canadian Pacific railway crosses the Kananaskis river by a bridge 
 that spans the stream about 2.50 yards above its mouth, and the Bow river by 
 another bridg? about 1 mile above the falls. The existence of these bridges has 
 a very ilirect tiearing upon the question of development at this point. 
 
 DEVELOP.MENT. 
 
 The general scheme of development adopted is that of a dam, placed across 
 the h(!ad of the fills, by means of which the water is raised and diverted into 
 .•I canal excavated on the south side of the river. The water will be conveyed 
 hy the canal to an intake structure situated on the .south bank and proviibd with 
 suiiiihle racks and gates for controlling tlu' flow. From the intake the water 
 will be cc iveyeii in pressure tunnels, to the wheels placed in concrete scroll 
 chambers situated lielow the power station, and thence in draft tubes to dis- 
 iharge tunnels leading to the river below the falls. The working head for which 
 lh<' plant is designed is 70 feet (see plans.) 
 
 Dam. 
 
 The dam at the head of the falls will raise the water to an elevation of 
 4,15.'> feet sea level datum; this elevation was finally determined owing to the 
 existence of the Canadian Pacific Railway bridge across the Kananaskis river, 
 about 250 yards from the mouth. The bridge is of the inverted truss type, and 
 the elevation of the lower chord was the controlling feature. Permission 
 was S! ■ ired from the Canadian Pacific Hailwav to raise the tracks at this

 point 3 feet. The new elevation of the bottom chord became 4,161.75. The 
 top elevation for Hash-boards and stoplogs authorized by the department has 
 been fixed at 4,155.75, or 6 feet below the bottom chord of the Canadian Pacific 
 Railway bridge over the Kananaskis. The dam is being built upon a ledge of 
 rock extending practically across the river (see plan), and is in three sections. 
 
 The first section, which is about 200 feet long, is nearly parallel to the centre 
 line of the canal; the shore end of this section is in the nature of a retaining wall, 
 while the outer 180 feet, or that portion nearest the angle, is of the spillway 
 section, made up of nine 17 foot openings with 3 foot piers between. 
 
 The central section is 174 feet long, and is provided with eight 17-foot 
 openings, with 3-foot piers between and one 24-foot opening in the nature of a 
 spillway. The section is built partially upon, and partially btlow, the ridge of rock 
 mentioned (see plans), and is provided with two inspection tunnels, one above 
 and one below the ridge; drains are placed at frequent intervals leading from the 
 face of the rock to the inspection tunnel. In addition, a line of holes is being 
 drilled along the face of the dam down through the rock, and grouted, the idea 
 being to close any seams that may underlie the dam. (See reproductions 
 pages 144 and 148). 
 
 The third section, forming the connecting link between the central section 
 and the north bank of the river, runs upstream, making an angle of about 30' 
 with the centre portion. It is 268 feet in length between abutments, and is 
 provided with eleven 18-foot openings, with intermediate piers 7 feet thi^k. 
 It is proposed to control these 18-foot openings with stoplogs operated from a 
 deck running the length of the dam, the bottom of the deck being at elevation 
 4,162. The elevation of sills of these openings has been finally determined as 
 4,138. Working level being 4,155, which may be raised to 4,155.75 by flash- 
 boards. This section is also provided with an inspection tuimel extending to 
 the north bank, and having an extension in the form of a drift leading into the 
 rock forming the north abutment; by means of this drift it is expected to cut 
 off possible leakage around the end of the dam and minimize danger to the 
 structure in that respect. In addition, holes were drilled in front of this wall and 
 then grouted under pressure. Access to the inspection tunnels is had by means 
 of a shaft in the block, forming the junction between the second and third 
 sections: this shaft lead.s to the tunnels, and also has an opening to the lower 
 side of the dam; there is also a shaft in the north abutment of the dam, leading 
 to the tunnels. 
 
 DiSCvIAKGING ('.\P.\CITV. 
 
 The discharging capacity of the structure under certain conditions is given 
 below in tabular form. It should be noted that, with the exception of the roll- 
 way and log run, the discharge is dependent upon manual operation, and is 
 not automatic except above elevation 4,155.

 Canal and Forebay. 
 
 Ihe canal is excavated in rock, sand and clay. The formation through 
 which It IS excavated is rather peculiar, owing to the great tilting of the rock 
 which IS to be found in all parts of the district, the rock surface appears as a 
 series of saw teeth, the intervening spaces being filled with clay, sand and 
 gravel ; through the rock section the canal is 72 feet wide, and in the earth 40 
 feet wide on the bottom, and 80 feet wide on top, the bottom elevation being at 
 4,140; It IS approximately 650 feet long. 
 
 The forebay to which the canal leads is divided into two bays, one for each 
 pressure tube, and these are in turn divided into two openings by central piers- 
 these openings are controlled by means of "Tainter Gates" though stoplogs,' 
 working in gains may be placed in the entrance piers. Each bay is 34 feet wide, 
 and each opening 14 feet, the dividing pier being 6 feet wide. The method of 
 operating is not definitely settled, but will be mechanical. 
 
 Pressure Tubes. 
 Easy entrance by wide passages is had from the forebay to the pressure 
 tunnels, whicn are of reinforced concrete and lead to the wheels situated in 
 wheel pits below the power house. 
 
 Power Station and Equipment. 
 
 The power station is built in excavation near the river bank. The necessity 
 of placing the station in excavation was determined by the economical length of 
 soud steel shafting connecting the generators and turbines. 
 
 The substructure is of concrete and the superstructure of steel and hollow 
 tile construction. 
 
 In addition to the electrical and hydraulic equipment described below, the 
 station ir provided with a 50-ton crane, pumps, etc. 
 
 T.ie electrical equipment will consist of two vertical shaft type, direct- 
 connected 3,750 k.v.a., 12,000 volts. 3 phase, 60 cycle generators, together wit' 
 nee ssary exciters and motor generator set, switch apparatus, etc.; 12,000 vo... 
 busses will be direct connected to the Exshaw line, no step-up transformers 
 being used. With this arrangement, power mav be delivered either to Exshaw 
 or Calgary through the Horseshoe Falls plant, the two plants being connected. 
 
 The turbines are vertical shaft type, each of 5,800 h.p. capacity with scroll 
 cases formed in the concrete, giving easy entrance to the wheels. The method 
 of installing these wheels is similar in many respects to that used at the large 
 plant at Keokuk on the Mississippi, 
 
 Market. 
 
 The market supplied with power from the Calgary Power Company'.s plants 
 IS within 50 miles of the stations, and the demand is concentrated at two points- 
 Calgary and Exshaw. At Exshaw the load is that derived from the cement 
 plantj which takes all the power delivered at this point; at Calgary the load is 
 that derived from the Canada Cement Company's plant, and the citv of Calgary. 
 The latter buys power from the power company and distributes it by means 
 of its own system. 
 
 The demand for power has been increasing rapidly ; the company first install- 
 Ai^^y ^'^^* ^•^'^- machines; this was at once increased by the addition of a 
 4,000 k.v.a. machine, and the latter is being duplicated, so that the equipment 
 will provide for a generating capacity of approximately 18,000 h.p. 
 
 In addition to the foregoing, the cnmp.any has at present under construction 
 the plant at Kananaskis falls, which when completed will have a capacitv of 
 10,000 h.p.

 SESSIONAL PAPER No. 25e 
 
 The city of Calgary has recently had an investigation made of the power 
 situation in its various pliases, and the results of this work, which was carried 
 out by Mr. R. A. Ross, C.E., of Montreal; are contained in a report by him. He 
 estimated the amount of power that would be required in the near future, i.e.. by 
 the fnll of 1913, at 12,000 k.w., and also that in ten years an output of 40,0(K) to 
 45,000 k.w. will be required, as.suming that the population will then be 200,000. 
 
 These figures seem large, but it is pointed out in the report: — (1) "That 
 you anticipate bonusing industries by means oi" cheap power "' 
 
 (2) that " owing to cheap rates, electric light will be universally used"; a-.id 
 
 (3) that "your output will be more readily absorbed by new industries, w'.iich 
 are not committed to any particular method of power development as in old'T 
 municipalities. . . . all of which will tend to make your demand' much 
 higher than for a similar sized municipality in the East."

 'iRowTH OF Power Load Demands Investigation. 
 
 The phenomenal growth of the country at large is of necessity reflected 
 in the growth in the demand for power, both for indvstrial uses and for light- 
 ing. This rapid increase in demand is illustrated in the history of the munici- 
 pal plant at Calgary, which, starting with a capacity of 260 k.w. in Noveml)er, 
 1905, has grown by leaps and bounds, practically doubling yearly, until at 
 present approximately 6,000 k.w. is installed in the station. 
 
 The history of the Calgary Power C<)iiii)any, which started to operate in 
 May, 1911, with two 2,500 k.v.a. machines is similar; the first two units wore 
 scarcely running when the installation of a third unit was commenced, and at 
 present th< " Hh is being installed in their Horseshoe Falls plant. Even with 
 this increji .ey are unable to keep up with the demand for power, and work 
 is now ill progress upon a second plant at Kananaskis Falls, which wlu-n com- 
 pleted will generate in the neighbourhood of 10,000 horse-power. These two 
 plants combined will give a generator capacity of about 28,000 horse-power. 
 
 It is reasonable to expect, therefore, that within a very short time the pre- 
 sent sources of power will be Ioade<l to capacity, and development at other 
 points will become necessary if pow^er is to be supplied by hydro-electric plants.

 CHAPTER VII. 
 
 POSSIBLE DEVELOPMENTS. 
 
 ^ General. 
 
 The possibility of further development of power upon the Bow river and 
 its tributaries is, owing to their topography, confined in a general way to par- 
 ticular stretches of the rivers. Upon the Elbow river the power-producing 
 part of the river is high up in the foot-hills, where it is confined to a narrow 
 channel by high banks, breaking through at times into wide flats which, being 
 confined at the lower end, afford possible power and storage sites. On the Bow 
 river itself, the power-producing portion of the river, as has been pointed out, 
 may be described as that part lying between Kananaskis falls and Calgary. 
 The lower part of this stretch does not offer an>' particular site, and only one 
 attempt has been made at development, namely, the Eau Claire plant at Cal- 
 gary, that has been already described. 
 
 Methods of Investigation. 
 
 The whole power-producing section has been investigated in a general way, 
 while particular attention was given to the part between Kananaskis falls and 
 Radnor, of which a complete contour survey was made. Studies were made 
 of a number of points on the ground, and a more detailed survey made of those 
 considered worthy of particular attention in the field. After study in the oflSce 
 of the detail plans of these points, it has been found that there are a number 
 worthy of consideration as feasible developments. 
 
 The same method was adopted on the Elbow river; there the stretch of 
 the river was studied carefully and after the consideration of several alternative 
 schemes, a single development, covering nearly the whole of the power section 
 of the river, was decided upon, and surveys were made. A storage scheme was 
 also worked out in connection with this development. 
 
 In order that these different schemes might be studied, and their feas- 
 ibility arrived at, layouts have been worked up for the different developments 
 with some degree of detail, and estimates based upon these have been made. 
 
 It is pointed out that these layouts are for study only, and should not be 
 considered as final designs. 
 
 The sites on the Bow river to which special attention has been given are 
 known as: — 
 
 1. Kananaskis Falls (being built). 
 
 2. Bow Fort. 
 
 3. Mission.

 The Bow river, after passing the Calgary Powei Company's plant at Horse- 
 shoe falls, flows between high banks for about 3 miles, and at very few points 
 in this distance is it possible to get dpwn to water level, the banks for the most 
 part being precipitous and rising to heights of from 49 to 150, and even 200 feet 
 in places. At several places the stream is very much confined (see topographical 
 sheets No. 4 and No. 4A and reproduction page 41), flowing through narrow 
 gaps in the rock outcrops. A point in regard to the geoloj^r of the river 
 is of interest here: Below the Horseshoe falls, the general dip of the rock 
 changes twice in a distance of 3 miles; at the Calgary Power Company's plant 
 the mp is towards the west (see reproduction page 35), about a mile below 
 the dip is east, while below the mouth of Bow Fort creek it has changed 
 to the west again. About a half a mile below the mouth of Bow Fort creek the 
 character of the banks imdergoes a change, and for a nimiber of miles below 
 this point high steep banks alternate with wide flats. 
 
 A numl^r of rapids and swifts occur between the falls and the point just 
 mentioned, the principal ones being about half a mile, and a mile and a half 
 below the falls, and one about three-quarters of a mile above the mouth of Bow 
 Fort creek. The total fall between the tail-race of the Calgary Power Company's 
 plant and the point below Bow Fort creek where the change in the banks takes 
 place, is approximately 70 feet. 
 
 Between the mouth of the creek and the end of the section just described 
 the banks are high and almost perpendicular, especially immediately above the 
 lower end ; j ust below the section there is a wide flat which lies on the south side of 
 the river at an elevation of a few feet above the level of the river, and it is at 
 this point, known as Bow Fort site that a detail study has been made. 
 
 SiTB. 
 
 Bow Fort site lies at the extreme lower end of the section just described, 
 about half a mile below the mouth of Bow Fort creek and three and three- 
 quarter miles tMow the plant at Horseshoe falls. 
 
 Just above the flat mentioned, the river flows between perpendicular rock 
 cliffs between ^0 <uid 50 feet high, and from the edge of the cliffs the banks rise 
 rather stee . ^ slope of 40 or 50 feet in two or three hundred, to the foot 
 
 of the mai: i Jcs on the south side; on the north side the slope is much 
 
 s'jeeper; .' < s are of soUd rock, thinly overlaid with soil. From edge 
 
 to edge of -^ le distance is only 265 feet, the general tilt of the rock is 
 
 towards th. ^ad the general characteristics of the site give the impression 
 
 that there was a tall in the river here at one time, the cliff having been cut back 
 until all that remains is a slight drop, which entirely disappears at high water. 
 The cause of this drop is a ledge of rock extending across the river; and it is 
 upon this ledge that it is proposed to place the dam, the intake being in the 
 south bank and penstocks leading to the power station situated on the flat 
 below. 
 
 Watbr Supply. 
 
 Under the present conditions of the river, that is without storage, the low- 
 water discharge between Kananaskis falls and the mouth of the Ghost may be 
 expected to go as low as 600 second-feet, though only for short periods (see 
 discharge curves). With the storage contemplated on the upper part of the 
 river, it is expected that a minimum flow of 1,500 second-feet will be obtained, 
 and it is upon this basis of discharge that the schemes above the mouth of the 
 
 25e— 5i 
 
48 DBPARTMWST OF TBS jyTXRlOR 
 
 S QEORQE v., A. 1>1S 
 
 Ghost are worked out; the intake structures and hydraulic eauipment are 
 designed for a flow of 2,000 second-feet, such a flow being available for a great 
 part of the year; the extra equipment would also act as a spare unit, or 
 stand-by. The flood that the structures are expected to discharge safely is 
 one of 50,000 second-feet. These, therefore, are the conditions of flow for 
 which the plant has been designed:— 
 
 A minimum flow of 1,500 c.f.s., with extra eqmpment for a dis- 
 charge of 2,000 c.f.s. to also act as a stand-by. 
 
 A maximum discharge of 50,000 c.f.s. 
 
 DSTEIiOPMCNT. 
 
 Several schemes of developing the power available at this point have been 
 studied, the one here presented being finally settled upon as the most feasible. 
 In order that these studies may be more comprehensive, designs have been 
 prepared and are included in the report, but these are for the purpose mentioned, 
 and are not intended as final. . . . 
 
 The proposed scheme places a dam across the nver at the point in question, 
 here the gorge is 265 feet wide, the walls are nearly perpendicular, and the nver 
 fills the whole of the bottom of the canyon. „i, , . , ^u * 
 
 On the north side of the dam line the cliff nses 25 feet from the water 
 surface, then slopes back for a distance of 50 feet, rising another 20 feet to the 
 foot of a rock cliff some 30 feet high, the intermediate slope being formed of 
 gravel and disintegrated rock from the cliff above. It is proposed to remove 
 this material and place four sluice-ways at the e^i of the dam, using the cliff 
 for the north abutment of the structure. 
 
 On the south side the cliff is higher, rising sheer 40 feet from the. water s 
 edae. From the top of the cUff the slope is steep, rising 25 feet in 100; this 
 sl^ is formed by the dip of the rock, which at this point is overiaid with soil 
 to a depth of only a few inches. 
 
 Head. 
 
 Bv placing the dam at this point a total head of 66 feet may be developed, 
 part of which is the natural fall in the river above the site, the extra two or three 
 feet being obtained below. To obtain this head, the water above the dain would 
 be backed up nearly to the taU-water of the Horseshoe Falls plant and about 
 2 feet would intervene between the head and tail-waters of the two plants. 
 
 Dam. 
 
 The dam proposed is of the hollow reinforced concrite type founded upon 
 ledge rock existing in the river-bed; it would be 265 feet long between the cliffs 
 of the river, and 350 feet long over all, including the sluice-ways; the total height 
 of the structure would be 75 feet, from foundation to spillway crest. 
 
 The dam would be provided with four opemngs 20 feet by 24 feet at the 
 north end, and controlled by stoney sluice-gates provided with ProPf' "P^'ating 
 mechanism and housed; these could be used for additional discharge during 
 SS,! In additioMhere would be two stoplog opemngs 16 f^t long, and three 
 72 inch valves controlling additional sluice-ways in the base of the dam. These 
 opeSs together with 200 feet of spillway section, will provide for a fiood dis- 
 
 Ji"!t If^S^fnSn^tere that, from Canadian Pacific. Railway Company^s 
 data relating to the high water in the Bow nver, the engineers of the Calgary 
 PowerSany have computed that the maximum flood discharge at Horseshoe 
 falls, which occurred in June, 1902, was 43,000 c.f.s.

0* DEPARTMENT OF THE INTERIOR 
 
 6 GEORGE v., A. 1915 
 Briefly, the method settled upon involves placing a dam across the river at 
 tne rock outcrops, together with some necessary embankment on the west side- 
 an mtake structure with controlling devices on the east side; an open cana 
 excavated m the top of the nver terrace referred to; a forebay With racks, over- 
 flow, and entrance to the penstocks; and penstocks to deliver the water 
 the dam°^" situated on the banks of the river almost 6,000 feet below 
 
 Head. 
 
 The water will be raised at the dam a height of 40 feet, and will back the 
 water upstream a distance of about i}4 miles to a point above Moriey bridee: 
 between the dam and the outlet from the power-house there is a further fall in 
 the nver of 9 feet, giving a net available head of 47 feet. 
 
 Dam. 
 
 The proposed dam is similar to that for the Bow Fort site, hollow and of 
 reinforced concrete. It will be 465 feet long, including spillway and sluice-ways, 
 and from the crest of the spillway to the foundation it will be about 55 feet 
 high, and wiU be founded upon rock. The extra discharging capacity will be 
 provided by means of sluiceways of the same dimensions and type as those at 
 Bow tort site, but on account of the '.idth of the river, no excavation will be 
 necessary; as above, there will be four 20-foot by 24-foot sluice-ways, controlled 
 by Stoney gates, and provided with proper operating mechanism; two 9- 
 foot by 16-foot stoplog openings will also bo provided, together with sluice- 
 way opemngs, through the base of the dam, 72 inches in diameter. The struc- 
 ture wll pass a flood of 50,000 c.f.s. with a 4-foot overtop. 
 K • o QoTl'?"*?^ " ^^^'^%^ ** elevation 3,866.00, normal water level at the site 
 being <J,825; the bottom of the stoplog openings at elevation 3,856 and the sluice- 
 gate siils at 3,841; an operating deck at elevation 3,871 will be provided for the 
 slmce-way section. 
 
 This structure is different from that at Bow Fort site, and the other sites 
 contemplated, m that there is no necessity for a bridge across the dam and the 
 whole length of the spillway will be unobstructed. 
 
 This type of structure has many advantages over the solid spillway type, 
 It IS cneaper, the difficulties of unwatering are reduced, and the question of 
 loundation is not as senous as with a solid masonry dam. 
 
 In connection with the dam it will be necessary to place an embankment 
 on the west side of the rock outcrop, forming the west wing of the dam; here 
 the ground drops about 12 feet below the contemplated spill-way level, the 
 embankment would be 225 feet long on the crest, and at elevation 3,871 or about 
 lb feet high at the highest point. It is proposed to place either steel sheet nil- 
 ing or a concrete core wall through the centre of this embankment, depending 
 upon the depth at which an impervious stratum of material is encountered. 
 iNo test pits have been sunk, so that it is impossible to say which will be the pro- 
 per course to pursue at this stage; ample provision has been made, however, 
 tor ordinary contingencies in the estimates. 
 
 Intake. 
 
 The intake to thp canal will be situated lit the cat^t end of the dam, and will 
 have Its face approximately at right angles to the centre line. This position 
 will secure the advantage of a current across the face of the intake which, with 
 a sluice-way between the intake and the end of the dam, will eliminate trouble 
 usually caused by ice and floating delirls Iwlging against the racks over the 
 
 if-^^KaamummmmM^ 
 
BOW RITER POWER AND STORAOE

 SESSIONAL PAPER No. 26« 
 
 intake. The total width of the intake is 95 feet, divided into four openings of 16 
 feet wide; the depth of the water at the intake will be 15 feet, and allowing for 
 the loss of section due to trash racks, the velocity of entrance will be about 3.0 
 
 feet per second. • • ^u 
 
 In addition to the trash racks it is proposed to place stoplog gams in the 
 
 intake piers, and also to provide the necessary stoplogs and operating winches. 
 
 As the structure will be built upon solid rock, means of shutting off the water 
 
 from the canal will thus be provided, in the event of such a necessity. 
 
 The whole structure would have a top elevation of 3.871, or 6 feet above 
 
 spillway elevation. That is 2 feet above the extreme flood conditions for which 
 
 the dam structure is designed. 
 
 Canal. 
 
 The canal proposed is 2,600 feet long; it will have a cross-sectional area of 
 525 square feet. The whole length of the canal lies in gravel, and on this account 
 the section adopted will have side slopes IJ to 1. The working level of the water 
 in the canal will be very nearly that of the original surface of the ground for the 
 whole length of the canal, and it is proposed to raise the embankment to eleva- 
 tion 3,871 for the whole length. On account of the nature of the material, it 
 is also proposed to line the canal with concrete for the whole prism, which will 
 not only prevent leakage, and possible breaks, but will materially reduce the 
 loss in head due to friction. 
 
 FOREBAY. 
 
 On accwunt of the similarity of their general features it has been 
 decided as far as possible to design the plants for the several sites along the 
 same lines. With this in view, a standard design of forebay has been adopted, 
 for the quantity of water to be handled is practically the same at each site; the 
 penstocks, too, can be made of the same general dimensions. .... 
 
 The delivery of water to each penstock, of which there are three, is obtained 
 by means of a bay 18 feet wide, with a depth of water of 20 feet at working 
 level. Each bay will be provided with racks and screens to prevent the entrance 
 of ice or trash from the canal. The water will be controlled by means of stop- 
 logs for which gains are provided, a duplicate set of gains being also placed in 
 each bay, as it is proposed to use a type of Stoney gat« capable of being used 
 in any one of the three bays, so as to obtain rapid control of all the water. VV here 
 the forebays are at the end of the canal as in this case, provision is made for 
 draining canal and forebay by means of a sluice-way ; this sluice will also take 
 care of any surplus flow due to suddenly closing down of any, or all, of the 
 
 machines. , „ , . - j *■ 
 
 The bottom of the forebay, in this case, is at elevation 3.844 a, and the 
 working level of the water 3,864 . 5, providing for a loss of head in the canal of 
 0.5 feet. 
 
 Penstocks. 
 
 The penstocks will be three in number, 10 f. ct 6 inches in diameter, and 
 265 feet long, supported upon concrete piers, antl will be similar in all respects 
 to the ones proposed for the Bow Fort site, except that they will be slightly 
 longer; very little excavation mil be necessary to place the penstocks on a 
 uniform grade. 
 
 Power Station and EqriPMENT. 
 
 The genial layout nnd siste of the power-house as adopted for the Bow 
 Fort site will be used at all the power sit*.", with the possible exception of the 
 Radnor site, which will enable estimates to \h> made sufficiently dose for the 
 purposes of this report, as the flow is nearly the same for all plants, and 
 the heads to be developed are nearly the same.

 «4 DaPARTMmiT OF THE ISTBRIOB 
 
 6 QEORQE v., A. 1915 
 
 The equipment at this will be a slight difference in si r e from that at the first 
 plant. 
 
 The power station would be situated about 100 feet back from the river, 
 at the foot of the terrace mentioned before; the drawback at this point is the 
 lack of evidence of rock in place underlying the heavy gravel which covers 
 the site; on this account care will have to be exercised in securing a foundation 
 for the station. The tail-race will be in the same material, and it may be found 
 necessary to line it with concrete. 
 
 The head to be developed at this point is 47 feet and, with 1,500 cf.s. 
 expected from the regulated flow, 6,410 b.L.p. can be produced, or 5,770 e.h.p. 
 output at the station. 
 
 The equipment provides for three units, the turbines each of 3,500 horse- 
 power, with governors, etc.; the electrical equipment proposed is three 2,000 
 k.w. machmes, with exciters mounted on the shaft of each, and these, together 
 with all switch apparatus, wiring, transformers, regulators, etc., are provided 
 for m the estimates. The power station would also be fully equipped with 
 crane, etc. Except for the difference in the capacity of the installation, the 
 station would be similar to that at the Bow Fort site. The size of the equip- 
 ment has been adapted with the idea that under certain loading conditions 
 two umts could handle the total load on the station under minimum flow con- 
 ditions, giving one unit as a stand-by. 
 
 The estimated cost of the development, based upon the layout and plans 
 outlined m the foregoing is here given: —

 Development. 
 
 The scheme proposed is to place a dam across the river at this point, with 
 the rock outcrops as abutments. In this position it will intercept not only the 
 flow of the Bow river, but also that of the Ghost, and this has an important 
 bearing on the scheme, by raising the water to the proposed level, the present 
 road and bridge over the Ghost will be flooded out, making it necessary to relo- 
 cate them; this may be done quite easily by diverting the road north before 
 it leaves the upper level, and an easy grade down to the Ghost river above the 
 proposed flood level may then be secured, also a good crossing point. The road will 
 then follow the new bank of the river downstream until it joins the old road; 
 this route, which is marked out, and may be seen on the plans, will cost very 
 little and will not increase the length materially. 
 
 The intake will be placed upon the south side of the river, and will give 
 entrance to a canal similar to the one proposed for the Mission site, though not 
 as long. At the lower end will be placed a forebay and penstocks, leading to 
 11 power station and tail-race. By this means some 6 or 8 feet of fall in the river 
 will be added to the head utilized, for an expenditure which is considered to be 
 warranted. 
 
 Flow. 
 
 The regulated flow of the Bow river will be augmented at this point by the 
 flow from the Ghost. The records of the discharge of the latter river do not 
 extend over a lengthy period, only two years being available, but records at 
 other places extending over a longer period, indicate that the winter of 1911-12 
 was one of low flow, and from the records it is concluded that a minimum flow 
 during the low v/ater period will be approximately 100 c.f.s. This will, with the 
 storage contemplated, give an available minimum discharge at the proposed 
 power site of 1,600 c.f.s. 
 
 Head. 
 
 The head it is proposed to develop will be secured by raising the water at 
 the dam to an elevation of 3,812.50 and by going downstream a sufficient dis- 
 tance to get a tail-water elevation of 3,762, or a net available head of 50 feet. 
 This head, together with the contemplated minimum flow of 1,600 c.f.s. will 
 give an output of 7,275 b.h.p. an output at the station of 6,550 e.h.p. 
 
 Dam. 
 
 The dam contemplated in connection with this scheme is similar to the 
 two already described in connection with the developments proposed at the 
 Bo^v Fort and Mission sites, i.e., a hollow reinforced concrete dam. The struc- 
 ture will be 450 feet long, including sluice-ways, and about 50 feet high, depend- 
 ing upon the depth of the foundation. The dam proper, will be approximately 
 300 feet in length, the remainder being taken up with sluice-ways, which will 
 be placed at the north end of the dam. Some excavation will be required, in 
 order that the sills for the large openings may be placed at the required eleva- 
 tions, and provide for entrance and exit for the water; the openings proposed 
 are the same as at other sites, four 20-foot by 24-foot sluice-ways controlled by 
 Stoney gates, and two 9-foot by 16-foot stoplog openings. Access to the north 
 end of the dam will be by means of a passageway through the structure, le.iv- 
 ing a clear spillway 300 feet long; in addition, sluices will be provided through 
 the dam at the south end, controlled by 72-inch valves, giving m all a discharg- 
 ing capacity of 50,000 second-feet., the dam being designed for a 4-foot overtop.

 The size of the units selected has the advantage of leaving a spare unit 
 avMlabie. Two of the turbine units under capacity load are practically equal 
 to the output of the station under low water conditions; under thwe conditions, 
 the generators would be working under a 25 per cent overload, which they 
 could maintain indefinitely; this may be said for aU the developments, the 
 stations being designed with that end in view.

 which must be added 100 second-feet, which is the discharge from the Ghost 
 to be counted upon during low-water period, giving a total of 1,600 second-feet; 
 the power to be developed is, therefore, 7,275 b.h.p., giving an output of 5,900

 SESSIONAL PAPER No. 2Sa 
 
 Development. 
 
 The method of developing the site involves placing a dam across the river 
 at the point mentioned, and making use of the rock cliffs as abutments for the 
 structure. 
 
 The intake which will be in the nature of a short canal, will be placed upon 
 the north side of the river, being excavated from the side of the cliff forming the 
 river bank and extending downstream past the dam about 30() feet. Its inshore 
 bank will be formed of rock in excavation, and on the river side it will be 
 confined by a concrete retaining wall designed to act as an additional spillway. 
 
 The forebay or entiance to the penstocks, will be placed at the lower end 
 of the intake or canal and will lead to penstocks of short length, which in turn 
 will convey the water to the power station situated on the river bank opposite 
 the second bend in the river below the dam (see plans.) 
 
 Flow. 
 
 The flow upon which the development is based is the same as that for the 
 Ghost site, that is, a minimum of 1,600 c.f.s. with structures designed to dis- 
 charge a flood of 55,000 c.f.s., with an overtop of 4 feet. 
 
 Head. 
 
 The head it is proposed to develop will be secured by raising the water at 
 the dam to an elevation of 3,760; the normal tail-water opposite the site of the 
 power station is 3,716, so that the normal working head will be 44 feet; this head 
 with the contemplated regulated flow of 1,600 c.f.s. minimum will give an out- 
 put of 6,400 b.h.p. or an output at the station of 5,760 e.h.p. 
 
 Dam. 
 
 The dam upon which the estimates have been based, is the hollow rein- 
 forced concrete type similar to the structures already described in connection 
 with the other sites. The dam will be connected to the spillway section forming 
 the retaining wall for the intake, and as access to the south shore may be had 
 through the dam, no deck will be necessary; this will give an unobstructed spill- 
 way of approximately 700 feet, which, together with the two 18-foot by 20- 
 foot sluice-ways that it is proposed to place next the forebay, will give ample 
 discharging capacity. Provision may be made for a log run at the south end of 
 the dam. 
 
 Intake. 
 
 The intake will be on the north side of the river and will be in the nature of 
 a canal, the entrance being in line with the upstream face of the dam; it will 
 be 50 feei wide and excavated to a sufficient depth to provide 20 feet of water 
 with the upper water surface at normal working level ; this canal will be about 
 300 'eet long, and at the lower end sluice-ways and an ice channel will be pro- 
 vided to clear any ice that may lodge against the racks, protecting the entrance 
 to the penstocks. The entrance to the intake will be protected by a timber 
 boom swung across from the bank to the north to deflect all logs and debris 
 over the main spillway. 
 
 Forebay. 
 
 The forebay will be in every respect similar to those of the other sites, 
 providing for entrance to three penstocks by means of bays 18-feet by 20-feet,

 BOW RIVER POWER AND STORAOE •» 
 
 SESSIONAL PAPER No. 26* 
 
 At the entrance to the canyon (see rei o<luction, paRC 66), and just below 
 the confluence of the two creeks, a dam was bmlt last year to proH ce 
 storage upon lake Minnewanka and improve the power facihties of the Bow 
 
 "^* The site of the proposed power plant is about 7 miles from the town of 
 Banff; communication with the latter place being had by means of a well-kept 
 and ^''vvelled road; this road, which also passes through Bankhead, the nearejt 
 point on the railroad about 3 miles distant, terminates at the lake. 
 
 Watkb Supply. 
 
 Any development at this point will be entirely under the jurisdiction of 
 the Government, as the whole project lies wholly within the Rocky Mountains 
 park, so that all privileges such as land, water, rights of way, are vested m the 
 Crown. The natural conditions on the river no longer apply, since the storage 
 and regulation works are complete und in operation, but the mfluence of these 
 works upon the operation of a power plant at the point contemplated will, 
 however, be entirely beneficial. i ,,. . . r *u t * • 
 
 When the agreement was entered mto between the Mimster of the Interior 
 and the Calgary Power Company, it was expected that the company woi^d 
 not be the only beneficiaries from the storage created, but that it wa^ possible 
 other plants might be built upon the river and receive benefits, a clause was 
 therefore inserted in the agreement enabling the Minister to control the operation 
 of the dam; this clause says:— , , , .. ■ j 
 
 "The company shall after the completion of the dam, maintain and 
 operate the same to the satisfaction of the Minister. . . ." 
 In connection with the necessary discharge of water from storage, sub- 
 clause "d" of clause 17 reads:— . . 
 
 "The company shall, if required by the Minister, allow a mimmum 
 amount of water of 150 cubic feet per second to pass througu the dam, 
 which the Government may use for power purposes within the Rocky 
 Mountains park; and the release of such water thro"gh the dam shall 
 at all times be under the full control of the Minister or person or persons 
 duly authorised by him for that purpose." 
 Any development on the Cascade below the dam, will therefore be assured 
 of a minimum flov of 150 second-feet. 
 
 During the early part of the flood season, the storage of water will take 
 pi- ; this will, it is expected, be completed not later than July 15 in any sej>son, 
 aiic. jvhich date water will be wasted over the dam. A flow greater thai 50 
 second-feet is practically assured during part of July, August and September, 
 so that the greatest power would be available during the summer months, when 
 the tourist traffic is greatest and the consequent power load heaviest— a very 
 fortunate combination of circumstances. 
 
 Available Power. 
 
 At the instance of the department, provision was made during the con- 
 struction of the storage dan. to use the structure a? a head works for the con- 
 templated power plant below; the dam produces at least half the head to be 
 developed, the other half being due to the natural fall in the river between the 
 dam and power site. As the pond above the dam is primarily for storage 
 purposes, there will necessarily be fluctuation in level; this will not, however, 
 affect the head unfavourably, for the low working head will occur during the 
 winter months, during which period the load will be small. A study of the 
 question of water supply has been made and the conclusions reached have been 
 included in another portion of the report.

 STORAGE. 
 
 General. 
 
 In 1909, work was cc >enced upon the plant of the Calgary Power Company 
 at Horseshoe Falls, thougn it was not until the winter of that year that actual 
 gaugings were made of the river during the low water period, and not until the 
 winter of 1910-11 that continuous readings were kept of the dischargt. 
 
 During January and February, corresponding to the time of minimum flow, 
 fairly complete records were kept; these corroborated the few readings made 
 ♦' e previous winter, and revealed a state of aflfairs that, to say the least, was 
 •larming. These records gave a mean minimum monthly flow of 741 second-feet 
 r the month of February, 1911, and showed that an actual minimum discharge 
 of less than 600 sec3nd-feet could be expected for short periods. 
 
 The plant built had a turbine installation, capable of an output of 7,600 
 b.h.p., with provisions to bring it up to 19,000 b.h.p. The situation was, there- 
 fore, a serious one for, under existing conditions, during six months of the year 
 w"»' .ras going to waste, while for the remainder of the year, owing to lack of 
 water, a peater part of the plant would stand idle. The demand for power was 
 ijeanwhile rapidly increasing, the only remedy was storage. By impounding a 
 P^'rtion of the water wasted during the flood stage of the river, the low-water flow 
 could be augmented and the situation very materially relieved; the loss due to 
 idle machinery would then be prevented.

 Storage basin. A survey of lake Minnewanka was made by the Calgary 
 
 Power Company with this object in view. 
 
 In the meantime, a policy of con.'^ervation and investigation had been formu- 
 lated bv the Railway Lands Branch, Department of the Interior, which at that 
 time handled matters relating to water-power, regardmg the question of water- 
 Tjower and storage. This l)ranch commenced active work in this <list net in the 
 snring of 1911; after a studv of the situation, and considerable work m the 
 nature of reconnaissance, a conclusion was reached by the engineers, which, 
 while entirelv independent, was pr-. ,-, .:'i. tho «ame as that of the engineers 
 empl..v<-d bv the Calgary Power C i.pMin , nuTn-iv that storage on lake ^ mne- 
 wanka offered the most immediat .clU-f to i i .• l-v er situation. 1 ..wards the 
 end of the summer of 1911, a par . .s se„t lu t. make surveys o, the lake to 
 determine what amount of storage . ,.:ild he con. nu-ally obtam.-.l. the am.mnt 
 of land to be flooded, and, in shor., a.i .i- 'cessary informaeu.n tha w.mid 
 enable the branch to deal with the matter: the n.)tes were worke. up in the ofhce 
 during the winter of 1911-12, an.l plans and computations ma.le. 
 
 The power situation on the R..w river was rapidly becoming worse. th..ugh 
 the records for 1911-12 did not slu.w quite such low water as for the previous year; 
 the market had increased, besides, this slight improvement was not a permanent 
 one. Fortunatelv when the ompany asked for certain rights, the l.rancJi, 
 owing to the work done in the field, had the situation thoroughly in hand, and 
 was in a position to dis.uss the situation with the company s representatives, 
 and make vertain recommendath.ns based upon information obtaine.l by its .)wn 
 
 ""owing to the urg.'n.-y of th.' situation, it Avas <lesirabl.> t.. ..btain an 
 increased flow for the low-water seas,m..f 1912-13. an.l to .lo tins th.- high-water 
 
 run-off during the summer of 1912 would n 1 t.. be impoun.le.l; ''^I'^'l'^"" "" 
 
 the part of all concerned was th.Tefore ne.'essary. pr.mipt action on the j.art ..f the 
 branch in granting li.-ence to the ...mpany to create storage and prompt 
 acti.m on their part in getting to w.)rk. i i i i- „ . f ..„.. 
 
 The policy the branch Iw.s had in nun.l was the contr..l and buil.hng of anj, 
 storage scheme, but this policy had not advanced to the state where the branch 
 was nrcpar.'d to take up the a.tual construction and control of storage: as the 
 shuation ,lei,.an<l<..l sp-Ulv action, and as only the b.-nefit f..r the pr,>s.-nt was 
 to the Calgary Power Company the actual building of the necessary works was 
 left to that Company.

 (44,000) acre-feet of storage. 
 
 " 0) The Government shall have the right upon giving the company 
 sixty days' notice in writing of the intent to do so, to take over, control 
 and operate the said dam upon the payment to the company of the 
 actual reasonable cost to the company of the said dam and of all work 
 required to be done in the Rocky Mountains park pursuant to said clause 
 twelve (12)." 
 
 Storage Basin. 
 
 Lake Minnewanka offered a splendid site for storage, and one capable of 
 very economical development. Situated in the Rocky Mountains Park, and in 
 close proximity to Banff, it required careful treatment in order that its value as 
 a resort for tourists would be enhanced rather than damaged. The lake is the 
 largest to be found in the Rocky Mountains Park, it is 9H miles long, and aver- 
 ages over half a mile in width; the waters are very beautiful, being exception- 
 ally clear and of a very deep blue, and surrounded as it is by high mountains 
 naany approaching 10,000 feet, it offers great attraction to the many tourists 
 thr.t visit the region during the summer. 
 
 The lake has an area of 5.37 square miles. The banks are generally quite 
 steep, and are for the most part from 15 to 20 feet high, though in places they 
 nse gently to the slope of the surrounding mountains, having a narrow beach 
 at the water's edge. The lake is very deep, and in consequence the shores slope 
 ofl rapidly into deep water. The south shore is heavily wooded for its entire 
 length, while the north shore is clear of timber in many places; the outlet end 
 of the lake is low, a considerable area being but 2 or 3 feet above the original 
 lake level. Devil's creek forms the outlet of lake Miunewanka; it is a little over 
 a mile in length, and joins the Cascade rl -er at the entrance to Devil's Canyon, 
 which is a narrow gorge in the solid rock, about 500 feet long; at the entrance,' 
 this gorge was about 40 feet between rock walls, and 50 feet deep. (See repro- 
 ductions, pages 66 and 75.) About a quarter of ami' - from the outlet of the lake, 
 an old dam existed, which kept the water at lake level, or 4 feet above its for- 
 mer natural level. From the foot of the dam to the mouth of the canyon the 
 fall was 14 feet. A dam placed at the entrance to the canyon would have tx 
 double advantage— the natural run-off of the lake would be stored, and also 
 the discharge of the Cascade river, the lake being used as a storage basin for 
 both. 
 
 Capacity, 
 
 After a study of the plans made, it was considered that storage to a depth 
 of 12 feet upon the lake was feasible, this depth meant the flooding of a consid- 
 erable area at the lower end of the lake and in the Cascade valley, rendering 
 necessary the diversion of the rof the replacing of a bridge, the moving of 
 some houses to higher ground am 'so the building of a new dock, with slips 
 for the boats on the lake, all of • h could be done at comparatively small 
 expense. 
 
 The area of the lake at nonnal level is 3,449.8 acres, and the area within 
 the 12-foot flood line is 4,009.9, thus the area flooded at the lower end of the lake 
 is approximately 600 acres. The storage in round numbers is 44,000 acre-feet. 
 (See diagram, Plate No. 9 for effect upon flow at Horseshoe fulls.)

 {Note.— The actual capacity of the basin is 44.700 acre-feet; of this amount 44,000 acre-feet has been 
 granted as storage, and it is upon this bavis that the following tables Nos. 11, 12 and 13 are worked 
 ut.) 
 
 Storage Capacity. 
 
 The limiting levels for storage created on lake Minnewanka were fixed 
 from the surveys made. The existing normal level of the lake was elevation 
 4,728.00, though this was not the natural level of the lake, which was some 4 
 feet lower, but had been raised to the existing elevation by a small wooden dam 
 placed in Devil's creek about oae-quarter of a mile below the outlet of the lake. 
 (See reproduction, page 72.) Thi^ dim waj still in place, and during the 
 winter 1911-12, it was cut and a stoplog opening made; stoplogs were put in 
 place, but could be removed with little labour. 
 
 The upper limiting level of the lake was placed at 4,740; 12 feet above the 
 existing normal level, giving 16 feet between former normal lake level and 
 the proposed top elevation. 
 
 The amount of storage available between elevations 4,728 and 4,740 is 
 44,700 acre-feet, an excess of 700 acre-feet over the amount of storage eranted.

OEPARTifBNT OF THE INTERIOB 
 
 5 GEORGE v., A. 191S 
 A depth of 0.2 feet in the lake would account for the 700 acre-feet, and as this 
 difference in elevation may easily occur between the lake and the dam, due to 
 storing or drawing down, the limiting elevations were fixed as above. (The 
 effect of this amount of storage upon th' Bow river at Horseshoe falls may be 
 seen by a reference to diagram, Plate Nc .,.) Between elevation 4,728 and 4,724 
 14,200 acre-feet of storage is available, and this may be made use of in conne*-- 
 tipn with a contemplated Government power proposition on the Cascade river. 
 
 CoNSTHtJCTION. 
 
 An agreement was entered into between the Water Power Branch and the 
 Calgary Power Company, and the construction of a dam in Devil's canyon to 
 provide for the impounding of water in lake Minnewanka commenced early in 
 the spring of 1912. Plans were submitted by the Company, and after examin- 
 ation by Mr. C. H. Mitchell, Consulting Engineer to the Water Power Branch, 
 certain modifications and additions were required. 
 
 Dam. 
 
 The plans submitted provided for a concrete dam to I placed at the en- 
 trance of the canyon. The dam consisted of a spillway se^,non with four spill- 
 ways and a sluice-way for unwatering, and a deck to act as a bridge, spanning 
 the canyon, and also to be used to carry the winch for operating the stoplocB 
 in the sluice-ways; provision was also made for a fishway, if required. The 
 changes recommended by Mr. Mitchell were made partly from a study of ihe 
 plans, and partly as a result of an inspection of the conditions existing in the 
 ground, these are embodied in the accompanying plani and are as follows- In 
 place of the deep sluice-way on the left of the dam, a penstock opening was pro- 
 vided with the necessary racks, intake piers, stoplog openings, etc. A steel 
 thimble to form the intake end of a penstock 5 feet in diameter was placed 
 this was 12 feet in length, 5 feet diameter at the lower end, and flared to an oval- 
 shaped opening, 5 feet 8 inches by 8 feet inches, so as to give the necessary 
 easy entrance; I-beams were also provided for holding racks. Certain pre- 
 cautions were also recommended and carried out in building. 
 
 The construction of the dam was an interesting piece of work. The place 
 iK very restricted, and in addition to that, it was necessary to take care of the 
 discharge of lake Minnewanka and Cascade river during construction. To do 
 this, a cofferdam was placed at the entrance to the canyon. A concrete block 
 (see plan No. 17) was first placed at one side of the river bed, the cofferdam 
 extending from the block to the opposite canyon wall; behind this a concrete 
 wall was placed and a flume built with the concrete block as the controlling 
 :yorka, the downstream end being kept at an elevation sufficient to allow the 
 river bottom under the flume to be cleared. The flume was built to provide 
 for a discharge of 300 c.f.s. with a depth of 18 inches (see reproduction 
 page 79). Excavation was carried on behind the cofferdam, and below the 
 flume; the conditions revealed were interesting; the bottom was covered with 
 heavy gravel and boulders to a depth of 8 or 10 feet, and the bedrock was wi.rn 
 into numerous pot holes (sec reproductions, page 79). The section contain- 
 ing the sluice and valve was placed first, the flume was then removed and the 
 ^f**u' ^'VPfted through the sluice-way, the other side then built to the level 
 of the first section; after which the whole was carried to the top elevation at 
 the same time. 
 
 Large scams existetl in the wall rock (sec reproduction, page 75). 
 Leakage through these was provided against by facing up with cnnfri'te nnd 
 allowing free discharge on the downstream side; possibility of erosion was in-

 sured against by the same method (see plan No. 17). The Cascade is a turbu- 
 lent stream and carries much silt and gravel in high water; to prevent any pos- 
 sibUity of th? valve clogging, the concrete cofferdam was left in, and a wall from 
 the cofferdam to the entrance of the (>luice-way was built, thus any material 
 carried by th^ water would be prevented from passing into the sluice-way.

 The dam was completed in May, 1912. The construction was carried on 
 by the Foundation Company of Montreal under contract with the Calgary 
 Fower Company, and both companies are to be congratulated for the expedi- 
 tion with which the work was carried out and the general appearance of the 
 structure on completion. 
 
 Cleabino Basin. 
 
 Simultaneous with the construction of the dam, the work of clearing the 
 margins of the lake and the area within the flood line at the lower end^ the 
 lake, and on the Cascade river was carried on; also such additional work as. 
 removal of buildings, clearing up the new townsite, buUding necessary road 
 diversions and improving the old road, changing the telephone line and build- 
 ing a new wtarf with slips for the boats on the lake. The clearing amounted 
 to nearly 600 acres, a great proportion of the flooded area being very densely 
 wooded, and as the department required careful clearing and low cutting of the 
 stumps, considerable work was involved. 
 
 A resurvey of the area devoted to summer cottages, and a change in the 
 layout was made, and some additional lots surveyed; the plot was then cleared 
 up, one or two of the streets were graded and the whole was left in good shape. 
 
 Bridge. 
 
 The road diversion necessitated a new bridge over Devil's creek; the i» • 
 bridge was considerably longer than the old one and was built entirely of ti' 
 ber, with the exception of the concrete foundation put in to carry the two ma . 
 •cribs. In order that the west end of the lake and the flooded portion erf the Ce • 
 tade river might be used for small pleasure crafts, the under side of the string 
 •ers of the bridge were placed 4 feet above high-water level, giving ample room 
 for boats to pass under. 
 
 The improvements made, such as new wharf, roads, bridge, etc., are illus- 
 trated in the accompanying illustrations. The work of creating storage on lake 
 Minnewanka was carried out very expeditiously; work was commenced in 
 March, 1912, a dam built in the canyon, over 600 acres of clearing done, a road 
 diversion of 1 mile made and regraded, a new bridge built, a new townsite sur- 
 veyed, and buildings moved out of the flooded area and in some cases rebuilt, 
 1 mile of telephone line rebuilt, a new wharf built and two slips provided, to- 
 gether with a marine railway for each, all of which was completed by the Ist of 
 July. The storage of water was commenced on June 1, 1912, and the level was 
 raised to 4,740 by August 12; the storage could have been completed much ear- 
 lier, but was held back by the. progress of the clearing, so that flooding did not 
 begin until the uate given. 
 
 Power in Connection with Storaqe. 
 
 Lake Minnewanka is 8 miles by road from the well-known mountain resort, 
 Banff, the visitors to which are rapidly increasing in numbers. This town is 
 the principal place in the Rocky Mountains park, and from here many camping 
 parties enter the mountains. As a place where people may spend the summer 
 either at the hotels or in summer cottages, it offers many attractions, and in 
 passing it might be mentioned that three times as many people visited Banff 
 during the summer of 1911 as visited the famed Yellowstone park. With this 
 increued population, the necessity of power for lighting streets and houses has 
 also increased; at present the power is supplied from the Bankhead mines, 
 which is ''• miles from Banff, on the road to Minnewanka; no franchise has 
 been gi^ , the street lighting being done by yearly contract.

BOW RIVER POWER AND 8T0RA0B

 SESSIONAL PAPER No. 25e 
 
 The park and town are under the Dominion Government control through 
 the Parks Branch, Department of the Interior. Under the conditions existing, 
 it was considered that a power plant oprated by the park authorities would 
 be a good thing; the feasibility of producing power in connection with the storage 
 in lake Minnewanka was looked into, and the conclusion was reached that such 
 was possible. Provision for the utilization of the storage dam as head-work« 
 of the power scheme was therefore secured, and the plans show the method 
 of making use of the storage dam as an intake for the plant. 
 
 Utilization of Flow for Power from Extra Storage. 
 
 In connection with the storage of water in lake Minnewanka, when the 
 agreement was made with the Calgary Power Company, granting them the right 
 to store water in the lake, a clause was inserted whereby the department reserved 
 the right to a continuous flow of 150 second-feet, to be used for development 
 of power or other purposes; in addition, the company was required to so modify 
 the design of the structure as to permit of it being made use of as head-works 
 for a power plant, the construction of which the department had in mind. The 
 discharge data in this connection is interesting, and some of the diagrams 
 included are to illustrate the utilization of the water discharged from storage 
 for that purpose. In making use of the water in such a manner, a continuous 
 flow is necessary, and in making provision for 150 cf.s. continuous flow it was 
 not the intention to work a hardship to the company, as there might be occasions 
 when it would be advantageous to conserve the storage as much as possible. 
 Having in mind this point, an investigation was made as to the effect o. the 
 department making use of 4 feet extra storage, not by raising the lake an 
 extra 4 feet, but by drawing it down to a lower level ; by this method, 14,200 acre- 
 feet could be made available. The diagram shown on Plate No. U, 
 together with Table No. 12, compiled by Mr. Johnston, was plotted with this 
 object in view; these are self-explanatory. The basin, as in the other case, 
 is assumed empty May 1, 1911, but at the lower elevation 4 feet below normal 
 lake level; deducting the 150 cf.s. reserved from the mean monthly flow, it 
 is found that the reservoir could have been filled by July 1, 1911, or 58,900 
 acre-feet could be stored. From then until December 31, 1911, 80,071 acre-feet 
 would be wasted, over and above the 150 cf.s. discharge. During the interval 
 of low water, i.e., with less than 150 cf.s. discharge, from January 1 toMay 1, 
 11,699 acre-feet would be required from storage, to make up the flow to loOcf.s., 
 or less than the extra storage secured by K wering ihe basin 4 feet below normal 
 lake level. So that, had it been necessary o utilize the storage at other than 
 the time it was required by the Calgary I'ower Company, it would still be 
 possible to pay them back out of the department's reserve. The method of 
 emptying the "basin is indeterminate, but filling is again commenced (at the 
 low level) on May 1, 1912, from which date to August 30, the limit of the data, 
 some 33,850 acre-feet, was wasted, after allowing for the 150 cf s. discharge 
 calleu for. In this scheme, as in the other, no detrimental effects are to be 
 expected from the slight delay in filling che basin, as by July 1 only the top rim 
 of the lake would be exposed. 
 
 It will be noted in examining the tables that the total storage capacity ot 
 the basin is given as 44,700 acre-feet for the 12-foot storage and 58,900 foet 
 for the 16-foot storage, and that only a run-off of 44,000 acre-feet has be<'n 
 granted; this is to provide for some leeway in regulation. 
 
 Utilization or Flow of 200 Second-feet with Extka Storage. 
 
 The scheme was then extended a little further, and diagrams and a table 
 prepared on the assumption of 200 cf.s. continuous run-off. The diagram, Plate

 basin at the beginning of the low-water season, and in this way each water user 
 may aid the other, and the discharge may be so adjusted as to be of the greatest 
 mutual benefit. 
 
 The storage of 44,000 acre-feet in lake Minnewanka provides for a con- 
 .^ous flow for five months of 160 cf.s. (see diagram, Plate No. 13), nearly all 
 ot this will become available for use in the power section of the Bow river; any 
 loss due to evaporation may be neglected, for after the basin is once filled there 
 IS more than enough flow to keep it full, and when the lake freezes, this loss is 
 practically stopped. 
 
 Under the general head of evaporation, all losses are included; that due to 
 ice IS the largest and the most difficult of determination. The storage in the lake, 
 - ich 18 held in the form of ice, is not all available until the latter end of April, 
 ..r even later, though doubtless the greater part of it will become available before 
 the general flood takes place on the river.

 Inflcbnce or Winter Conditions on Dibcrarob from Storage. 
 
 The dissipation of storage through the formation of ice, and the extern 
 of Its influence has required considerable attention. During the winter 
 1913-IQI3, a study was made of the situation. The release of wnter from 
 lake Minnewanka the last winter was not attended with unmixed succefls from tht.

 power standpoint. One reation for this was the distance between the storage 
 basin and the point of utilization, approximately twenty-four hours being 
 required for water from tne lake to reach the power station, thus close regulation 
 was prevented; a >ichtme is now on foot to remedy this. Another adverse 
 influence was the formation of ice in the bed of the Cascade river, and overflow 
 of the valley. This condition existed to a very marked degree between Bank- 
 head and the junction with the Bow, for as is the case with all rapidly flowing 
 open streams during extreme cold weather, large quantities of frazil ice was 
 formed in the Cascade; this ice formed blockades, dammed back the river, flood- 
 ing the flats where the water was turned into ice. Nearly the whole of the section 
 referred to was covered with a sheet of ice, extending across the valley. In 
 
 {tlaces this ice field was two or three hundred yards across and of a depth of 3 
 eet. Where the valley was more confined, the sheet was not so wide, but was 
 as much as 7 feet thick (see reproductions, pages 19 and 25). No doubt, 
 the formation of anchor ice had something to do with the flooding, but frazil 
 appears to have been the greatest cause, coupled with other conditions. 
 
 From a study of the discharge curve of lake Minnewanka during the winter, 
 together with the temperature curve for the same period, the following con- 
 clusions have been drawn. During the periods of comparatively mild weather, 
 little water was flowing in the river, the channel became very much restricted 
 and clogged with the ice margins and hard auow. Directly a cold snap came, 
 a considerable quantity of water was releasid, frazil formed, and blocked up the 
 restricted channels, the flats, overflowed and froze, causing ice fields. 
 
 From an examination of the other streams in the vicinity, this explanation 
 is apparently confirmed, because little evidence of overflow and ice formation 
 existed at the end of the reason. The normal flow apparently did not have the 
 same effect as that of a regulated stream where little water flowed during normal, 
 and large quantities during severe weather. 
 
 It is expected, in view of this, that with a plant in Cascade below the dam, 
 and a consequent continuous flow of considerable volume, little difficulty will 
 be experienced from ice after the plant is installed. 
 
 The loss of water due to ice formation in the stream is rather a loss of regula- 
 tion than actual loss of water, as nearly all eventually becomes available during 
 the latter end of the low-water period, the ire in the streams disappearing long 
 before the high-water period. 
 
 SPRAY LAKE AND RIVER. 
 General. 
 
 The Spray river, one of the largest tributaries of the Bow west of Calgary, 
 joins that stream in the Rocky Mountains park, at Banff, just be'.ow the Spray 
 falls on the Bow. Flowing from the south, it enters the Bow valley l)ctwe<'n 
 mount Ruiiiile and Sulphur mountain; it is between 40 and 50 miles lt»ng from 
 source to luuuth, and has a drainage area of 310 square miles. About 8 miU-i 
 above the mouth, the river branches, one branch, the east antl smallest, flows 
 from the valley between mount Rundle and CJoat mountain. 
 
 The west branch comes down the val!<>y on the other side of the (^loat range. 
 The fall in the river is fairly regular, about 40 feet per mile, the valley is very 
 narrow and the banks are very high and precipitous. From the junction up- 
 stream for about 17 miles, this branch flows through a narrow valley between 
 the Ooat range and the range to the west, and the total drop in the distance is 
 750 feet. In this stretch there are very few creeks of any size coming in; the 
 pomibility of po.trer has not been investigated, but it is quite possible that a 
 limited amount, such as that to be develoi^d on the Cascade in connection with 
 the storage at lake Minnewanka, might be developed.

 At the end of this stretch of the river, it breaks up into three branches, the 
 main branch from the south, one which forms the outlet of the bpray lakes 
 and Hogarth creek. (See reproduction, page 95). *u i n u 
 
 The principal branch is from the south. About 5 miles above the lakes it 
 divides into two branches, one to the east heading on the main continenta 
 divide in a small lake, and the other from the west having its source in a small 
 lake under mount Assiniboine. The fall in these two branches is considerable, 
 but no records are available as to the slope. 
 
 Hogarth creek is rather small, and flows between the Spray and Kananaskis 
 ranges, heading on the divide between the Spray and Kananaskis rivers.

 The Spray lakes, three in number, lie to the north of the river. They are 
 connected with it by a stream about half-a-mile in length, which enters just 
 below the mouth of Hogarth creek. The lakes lie in the mam valley between 
 high mountains, and are connected by small streams. The lower and larnest 
 lake is 301 acres in extent, and lies at an elevation of over 6,000 feet, given on 
 the maps as 5,396, but assumed for purposes of survey at 5,260 feet. The

 creek from the east and the outlet of the lakes from the north ; and at the junction 
 of these creeks a wide valley is formed. About one-quarter-of-a-mile from the 
 lower lake, just below the junction of the branch from the lakes and the main 
 stream, the nver leaves the valley through a narrow canyon, the walls of which

 «re of rock formation, covered, to a greater or less extent, by soil and detritus, 
 «ad are wooded. These walls rise on a slope of not less than 60°, to a height 
 of at least SOU feet, the rock outcrops being nearly perpendicular for a great por- 
 tion of their height. (See reproductions, pages 85 and 86). This ccnyon extends 
 downstream about a mile, the stream filling rapidly; the width at the 
 water level U from 60 to 150 feet, and at an elevation of 150 feet above the water, 
 between 400 and 450 feet. 
 
 There is evidence of rock above this point, and on the south side an outcrop 
 appears at an elevation of over 160 feet above water level, and extends up and 
 down stream as far as was examined. 
 
 The rock on the south is of limestone formation, and appears to dip towards 
 the south, and is overlaid to a considerable depth with a glacier deposit. On the 
 north side the rock resembles a sandstone formation, the valley having been 
 formed apparently in the fault between the two formations as on the north side 
 the dip is practically vertical; the rock rises higher, and is overlaid to a greater 
 depth than on the south side, the outcrop appearing at least 200 feet above the 
 level of the water. 
 
 The conclusion reached from the reconnaissance was that, by placing a 
 dam in this canyon, as near the mouth as practicable, considerable storage 
 could be developed in the basin behind. 
 
 Survey. 
 
 The survey made of the basin in the summer of 1912 was made with the 
 object of verifying the conclusions reached in reconnaissance. The work 
 was done as rapidly as possible by plane table, and with a degree of accuracy 
 commensurate with the object in view. Special attention was paid to the canyon, 
 which was contoured with care, with the object of locating several dam sites, all 
 rock outcrops, etc., were located in order that fairly close estimates might be 
 made of the probable cost of control structures. 
 
 ^ A careful study was made of the canyon at the time the survey was com- 
 menced, and it was decided to make the 5,300 feet contour (lake level, 5,200), 
 the limiting elevation, as far as the structure in the canyon was concerned, 
 though it was not certain at the time that this would not lead to difficulties 
 in other parts of the valley. With this in mind, the contours were developed by 
 the plane table, particular attention being given to the 5,250, 5,275 and 5,300 
 contours, though sufficient information was taken to develop the intermediate 
 ones at 10 foot intervals. 
 
 ; The method pursued was to run traverses with the plane table, making use 
 of two rod men, sometimes the packer was pressed into service. Vertical angles 
 were read. 
 
 No attempt was made to follow out a contour by horizontal shots, but by 
 controlling all the changes in the ground, and sketching, on the ground, the 
 country was developed. Frequent checks were made to eliminate errors. When 
 the sheets were finally assembled, it was found that the traverses closed well 
 within the permissible error for such work, and frequent checking for elevation 
 exhibited the same condition. 
 
 In referring to this basin it seems well to draw attention to this method of 
 survey. Where the country is of such a nature that control of the ground may 
 be had, there is no doubt that the plane table will give result" quite accurate 
 «nough for preliminary work and if extra care is taken, results may be obtained 
 upon which final estimates for the creation of storage may be based. The 
 personnel of the party has been given before, but is repeated: one plane table man 
 (engineer in charge), two rodmen, one handy man, one packer, and eight pack 
 horses; on moving days the handyman acted as packer, and at odd times he

 cooked and, when the party was working in timber, he acted as axeman. This 
 party operated 30 miles from the base of supplies. Including the time of moving 
 m and out, and actual work in the field, but excluding the cost of the work of 
 the chief engineer, the work was done at a cost of 25 cents per acre, which, 
 considering the value of the data secured, is very reasonable. 
 
 Area and Capacity. 
 
 The area contoured was roughly eight and one half miles long and three- 
 quarters of a mile wide, giving inside the 5,300 contour, an area of 3,024 acres. 
 This includes the three lakos in the valley and also the falls on the main branch 
 of the river. The area inside the 5,275 contour is 2,429 acres; inside the 5,250 
 contour, the area is 1,755 acres; and inside the 5,220-foot contour the area is 
 729 acres. The quantity of water that could be stored below each contour is 
 171,129, 102,829, 49,986 and 11,880 acre-feet, respectively. A curve giving the 
 contents of the basin at each foot of elevation shows that the storage capacity 
 mcreases much more rapidly at the top of the reservoir than at the bottom. 
 This curve, which is remarkably regular, emphasizes the advantage in storage 
 capacity to be gained by raising the control works as high as possible. The 
 assumption has been made in this report that the basin will have its upper 
 level at 5,300, giving, in round numbers, a total storage of 171,000 acre-feet; 
 of this amount, 160,000 acre-feet has been made the basis of all calculations, 
 the remainder it is assumed being dissipated as evaporation or otherwise. 
 
 if' 
 
 Discharge. 
 
 The gauging station on the Spr-jy river, established in July, 1910, is located 
 about 100 yards above the junction .fith the Bow, and in consequence the total 
 discharge of the river is measured at that point. The records have been kept 
 contmuously since the establishment of the station, except for the month of 
 November, 1910. 
 
 The only stream of consequence entering the Spray between the gauging 
 station and the lakes, is the branch coming in at the end of Goat mountain; the 
 discharge from this stream forms, however, but a small proportion of the total 
 flow. The river heads for the most part in the glaciers and snow fields of the 
 summit range, so that it is safe to assume that fully three-fifths of its discha-ge 
 comes from above the entrance to the canyon, near the Spray lakes. 
 
 The results of the gaugings are tabulated and included with data of a like 
 nature. A diagram (see plate No. 5) shows graphicallv the mean monthly dis- 
 charge of the river over the period recorded. The discharge for the period, 
 October 1, 1910, to October 1, 1911, excluding November, 1910, is 398,687 acre- 
 feet; it may therefore be assumed that the discharge was well over 400,000 
 acre-feet for the whole period. The records do not extend over a sufficient period 
 to enable any definite conclusions to be drawn, but the amount of water avail- 
 able for storage during the high-water period is estimated to be about twice 
 that of t.he capacity of the storage basin. 
 
 From the discharge tables it will be seen that the minimum mean monthly 
 discharge for the period recorded w«. i08 c.f.s. in March, 1912. The maximum 
 mean monthly flow was 2,011 c.f.s. in June, 1911. The absolute minimum daily 
 flow recorded was 75 c.f.s. on March 29, 1912, and the maximum daily discharge 
 was 2,840, June 18, 1911. It is interesting to note that the period of minimum 
 flow is apparently during the month of March rather than February, as in the 
 other streams, but whether this will always hold true, and the reason for it, is 
 not apparent.

 Another diagram, Plate No. 14, has been prepared showing certain con- 
 ditions of filling and emptying the storage basin baised upon the recorded discharge 
 of the river. In this connection it was necessary to make some assumptions as to 
 the amount of water to be discharged during the operation of filling the reser- 
 voir, a discharge of 316 c.f.8. was therefore provided for, and the length of time 
 necessary to fill the reservoir, and the amount of water wasted in excess of this 
 flow was computed. It has been anumcd that during the high-water period of 
 1910, the reservoir was filled; at the be^nning of November, water was first 
 released from storage and added to the mean monthly flow. 
 
 The distance of the basin from auy point, other than one on the Spray 
 river at which the water could be used for power purposes, is great, so any 
 attempt at close regulation would be futile. It would only be possible to regu- 
 late upon the basis of a continuous flow of the Spray river itself, and it is upon 
 this basis that the diagram for the stream has been compiled. Assuming that 
 the intention is to augment the flow of the Bow river during the months in 
 which low water occurs, would mean a flow from storage during six months of 
 the year or from November 1 to May 1. With 160,000 acre-feet of available 
 storage, a continuous flow of 446 c.f.8. could be maintained, adding the mean 
 inonthly flow of the river during these same months, and assuming that a con- 
 tinuous uniform flow is maintained, it would be possible to secure a discharge 
 of 635 c.f.8.; making the same assumptions, and using the same reasoning, 
 during the low-water period, 1911-12, 607 c.f.8. would be the continuous uni- 
 form flow for the period. 
 
 On the assumption that a flow of 316 ci.s. is being provided during the 
 storing period, and that filling the basin commences on May 1, it is found that 
 for the year 1911 the basin could have been filled by July 23, 171,000 ncre-feet 
 being stored. From the time of filling to the time of commencing to discharge 
 from storage, 64,937 acre-feet would be wasted in excess of the flow of 316 c.f.s. 
 provided. From the year 1912, su£5cient data are not to hand to compute the 
 time of filling and the amount of waste. 
 
 Creation op Stobaoe. 
 
 The best storage scheme in the Bow basin is undoubtedly that at the Spray 
 lakes, though the proposition is not an easy one. The amount of additional 
 water that could be made available would form a considerable percentage of 
 the present low flow. 
 
 The size of the structure involved is great so that considerable care and 
 thought will have to be exercised in the final design and construction ; it is quite 
 possible that if the proposition is undertaken, the general scheme as advanced 
 now will require modification in many ways. With the information that is now 
 available it is, however, considered that the creation of the amount of storage 
 assumed is feasible, from both an engineering and economic stand-point. 
 
 Type o» Stbucture. 
 
 The estimates for the cost of creating this storage basin are based upon 
 the design of a hydraulic-fill type of dam. 
 
 Htdraulic-Fill Daub. 
 
 The hydraulir -fill tjrpe of dam belongs essentially to the western mining

 the methods of excavating, transporting, and placing material to form a dam was 
 originated, and it might be said that to the engineers of that section of the coun- 
 try belongs the credit of raising the method to its present high plane. 
 
 This type of dam is not confined to structures of low height, there being 
 examples in existence of dams, built by thb method, of heights varying from 77 
 feet to over 200 feet. Dams of this type are built of clay, gravel, rock and sand, 
 which has been excavated and placed in position in the structure by means 
 of water conveyed in pipes or sluices. Generally speaking, the material is 
 excavated by the same agent, streams of water at a high velocity being directed 
 against the material in its natural bed. 
 
 Mr. J. D. Schuyler, an authority on the subject, has, in a paper before the 
 American Society of Civil Engineers, gone into the subject thoroughly. He has 
 described in detail a number of dams of this type, amongst which are the fol- 
 lowing (Trans. Am. Soc. C.E., vol. LVIII):— 
 
 1. Crane Valley dam. 
 
 2. Terrace dam. 
 
 3. Lake Francis dam. 
 
 4. Tylei dam. 
 
 6. Como Lake dam. 
 6. Necaxa dam. 
 
 To this list may be added the Coquitlam dam in British Columbia, which is of 
 particular interest, being a Canadian example. 
 
 Site. 
 
 The site of the proposed dam at Spray lakes, us has been mentioned before, 
 lies in a narrow canyon near the outlet of the lake. The banks or walls of the 
 canyon are composed of rock (limestone), which rises at an angle of about 60° 
 to a height of approximately 170 feet. Above that elevation the banks are of 
 a glacial deposit, composed of clay, gravel, sand and boulders, overlying the 
 rock on the south side to a depth of from 50 to 100 feet, and on the north side 
 T?u* ™f*''' P"®**®'' height, the slope being almost as steep as the lower part. 
 The rock at the lower level of the canyon is completely buried in places by 
 material from above, and only appears as an outcrop on the south side. On the 
 north side It presents a rock face for 100 feet in th< height, here the rock is 
 rather badly decomposed. At elevation 5,300 or 140 f.et above the water level 
 the width of the canyon is 380 feet. ' 
 
 The above conditions may be considered ideal from the standpoint of a 
 hydraulic-fill dam. The surroundings are such that good borrow pits could he 
 had near the site, and at such a height above the work, that no difficulty w .uld 
 be experienced in regard to grades in the sluices; an ample water supply exists 
 m the river, which would of course reed to be pumped. 
 
 The matter of unwatering th? site during con^truption is comparatively 
 easy. The proximity of rock to the surface would primit of the constriirtion 
 of a tunnel of comparatively short length, which conUI hp built with the ulti- 
 mate object of discharcing the storage.

 rocks roll more readily than broken angular chips, and clay a*-ts as 
 a lubricant to assist m transporting the heavier materials 
 
 "The most difficult material with which to build such a dam is pure 
 clay unmixed with sand, because it is unstable until the water is drained 
 from the mass, and drainage is slow. The shrinkage, therefore, is much 
 greater than in other materials, and there is greater likelihood of the 
 opening of shrinkage cracks, months after the work is finished, through 
 which leakage could start if the dam were put in service too soon after 
 completion. When clay is finally consolidated, however, it makes a

 desirable, and its presence with sand, gravel, and rock in sufficient pro- 
 portion to form one-fourth to one-third of the volume of tie dam to be 
 segregated by water and placed in the centre of the mass, makes it more 
 easily worked, more useful, and more valuable for safe dam construc- 
 tion than in any greater proportions. 
 
 "While clay is doubtless the most impervious of all earth, it is not 
 indispensable m the building of water-tight dams. The volcanic ash 
 xjil of the Snake River Valley has none of the characteristics of clay 
 -ind yet it is so finely divided as to make a -ater-tight embankment 
 when properly moistened and compacted. (iluda\ flour, which has no 
 resemblance to clay, will also make an equally good dam." 
 The creating of storage at Spray lakes, with whatever type of structure 
 that may ultimately he decided upon, involves the question of transportation. 
 SituatxHl as the site w. up m i\w mountains, and at ;i distance of 30 miles bv trail 
 trom Banff the expense of transporting materials ^ucii ; distance over mountain 
 roads would be great, ami there is the initial expense nf buiWing at least 20 
 miles of aew road; any scheme of .(uiwtructio* therefor*- wh»eh reduces the 
 amount of matenals to be transp«»rt*d is worthy ®r consi^iTation. It has been 
 e8tiniat.'d that the cost of eement landed at the me of the work would be at 
 least S6 per Vwrrel by the cheaper^ meth.Mi of traiM-portation, i.e., in winter 
 when the roads would !«• gwKi and the loads hauled kw^e; cimerete construction'

 wouW reduce the amount of material to t>p transported to a minimum. The 
 amount of material to be placed in the structure is greatlv in excess of that 
 for :i concrete dam, but there is no citmparison In'tween tlie unit co«t for the 
 methods, there being cfrntracts on record where the price for this kind of work 
 has Ijeen 18 cents per cubic yard. 
 
 ►•' Mr. Schuyler, in his paper (vol. LVIH, Trans. Am. Soc. C.E.) quoted before 
 says regarding this method : 
 
 "While economy in first cost is certainly a most potent factor in 
 governing the choice of methods of doing any work, it is by no means 
 the only reason which has le<l the writer to advocate a widespread and 
 general use of the hydraulic-fill method of dam construction. He regard, 
 its sur>erionty as consisting largely in the ability afforded to utilize 
 materials which would be otherwise unfit or unsuitable due to the a.ssort- 
 ing, grading and separation of different classes of material, bv reason of 
 the dissolving action of moving water and its varying velocitics,which are 
 entirely controllable, and which permit the deposition of the several 
 grades in making a stable dam. Bv this means, the course, friction- 
 beanng stable materials may be placed on the exterior slopes, and the 
 fincT particles may be assembled in the centre of the mass to serve as a 
 puddle core, and the ease and simplicity with which this may be done 
 constitutes one of the stningest pofwible re.isons aside from that of economy 
 in cost, for using this method. In fact, by this process it becomea practic-

 able, with care and skill, to build a safe and stable dam of materials 
 which would otherwise be considered valueless. As nature does not 
 always mingle her materials in the proper proportions to make them 
 fit for forming a water-tight embankment without proper segregation; 
 this selection and separation cannot usually be made by the ordinary 
 process at practicable cost." 
 
 Construction. 
 
 The first consideration in construction of this kind, is the question of water 
 supply under pressure. This is obtained in one of two methods— either by meanp 
 of a gravity supply at an elevation above the work suflBcient to insure a good 
 working pressure, or by pumping; the former method is the cheaper. The 
 pressure is, of course, of prime importance, and as a rule at least 100 pounds 
 per square inch is required with a discharge up to 20 cubic feet per second. Where 
 the supply of water and the pressure is secured bv pumping, power has to be 
 secured. 
 
 At this site, so far as is known, there is no adequate gravity supply of 
 water available; it is therefore proposed to obtain the required supplj- of pump- 
 mg, a method for which the site is well adapted. 
 
 Power for Construction Purposes. 
 
 At the upper end of the basin, and in the main branch of the river, there is 
 a fall with an available head of 50 feet. The flow varies, but during the season 
 when sluicing could be done, the amount available would be between 150 and 
 200 second-feet. When the basin is filled, the fall will be drowned out, but 
 during construction it would be available for power. It is proposed to install 
 a temporary power plant at this fall. This could be done very economically, 
 a^'l such a plant would supply all the power necessary for the construction of 
 the dam; the fall is about a mile and a half from the site of the proposed work 
 so the transmission lines would be short. Altogether, the site seems peculiariy 
 adapted to this type of construction. 
 
 Dam. 
 
 The dam would occupy the same position as of that proposed for a iiiiiMinry 
 (lam. I.e., about 2,500 feet from the mouth of the canyon. It would be 380 feet 
 long on top and 30 feet wide, and from foundation to crest, the total height 
 would be 100 feet. A design has been prepared of the structure, and quantities 
 estimated. 
 
 The upstream slope i<« 3 to 1, and the .lownstream 2 to 1. Riprapping is 
 also included for each slope, but owing to the material this may \>e found to ]te 
 unnecessary. A rock toe is proposed at the up and <lown stream side of the ilum. 
 
 The necesnity for a core wall in the heart of the dam cannot be definitely 
 decided until the foundation is uncovered. Regarding the advisability of the 
 use of a core wall in connection with hydraulic-fill dams there seems" to be a 
 wide difference of opinion; there is no lack of examples of brth the use and 
 omission of core walls. The Terrace dam and Necaxa dam No. 2 are good 
 examples of the use of core walls; in the former case the wall fills the lower part 
 of the canyon and rises to a height of 70 feet, and in the latter caw the <ore wall 
 extends down through the underiying material to an impervious stratum and 
 rises to within a short tlistance of the original surface of the ground. On the other 
 hand, a notable example where the core wall i« omitted though not entirely is 
 the (oquitlam dam in British Columbia, at the outlet of Coquitlam lake, the 
 core wall being only built on the side of the confining vallev where rock is in 
 place.

 In connection with the need of core walls, in a discussion of the paper 
 before quoted, Mr. Schuyler says: — 
 
 "The fixed objection which the writer has to a core wall of masonry 
 or concrete in the centre of an earth dam, especiidly of large dimensions, 
 is that it introduces an element entirely foreign to the nature of the 
 body of the earth structure, acting as a huge knife to sever it in half, 
 destroying its homogeneity, and preventing the complete knitting m^of 
 the mass as a whole in a manner that must best subserve the purpose 
 for which it was built. A core wall must necessarily be built compara- 
 tively thin to be reasonable in cost, and must be subject to the minor 
 defects of .'onstruction incident to all such work, and subject alsoito 
 rupture from the possible uneven settlement of the earth on cither side of 
 it." 
 
 The placing of a core wall in the dam depends upon the nature 
 of th« material upon which it is founded. If based upon an impervious 
 stratum of clay, or material to which a good bond may be secured, its introduc- 
 tion seems unnecessary. On the other hand, where the dam is placed upon 
 rock, it would appear that some method should be used to prevent possible 
 percolation along the line of contact, either by trenches filled with material 
 bonded to the dam, and homogeneous with it, or bv a low core wall. Mr. 
 Schuyler gives it as his opinion that: "A core wall of moderate height in an 
 earth dam founded on bedrock, is a most useful and necessary element to form 
 a bond between the earth embankment and the bedrock on which it rests, but 
 for this purpose it does not need to be carried higher above the rock surface 
 than is reasonably necessary to form such a bond." 
 
 It is proposed to make the unwatering tunnel serve the double purpose of 
 takmg care of the flow of the river during construction, and of serving as a 
 means of discharging the water from storage when complete. This tunnel will 
 be placed in the solid rock at the north end of the dam, the entrance at the 
 upper end bemg constructed with proper intake structure, and the tunnel lined 
 throughout with concrete. The discharge will be controlled by suitable valves 
 placed in a chamber excavated in the rock, and situated above the tunnel, access 
 to which will be by means of a shaft sunk from the surface at some distance from 
 the dam. This tunnel will be of ample size to take care of any flood discnarge 
 that may occur. 
 
 Spillway. 
 
 A spillway to supplement the sluice tunnel at times of excessive flood may 
 be provided at either end of the dam, depending upon the nature of the material 
 encountered.

 BOW LAKE STORAGE. 
 
 General. 
 
 Bow lake at the head of Bow river is at an altitude of nearlv 6 500 feet 
 above sea-level, ami may he considered the source of the river. On the south 
 side of the lake the mountains rise from the water's edge from 2,500 to 3 000 feet 
 
• DBPABTMBNT Of TBE IHTgKIOK 
 
 5 GEORQE v., A. 191S 
 
 but on the north and east sides the slope is gentle, the valley wide, and the moan- 
 tWM not so high- About 3 miles to the north west of the lake, is Bow pass at 
 an eleration of 6,870 feet, forming the upper limit of the Bow basin. 
 
 The mountains to the south and west of the lake are for the most part per- 
 petually snow-capped, immense fields of snow lie upon the top of Bow peak, 
 mount St. Niebolas, and others in the vicinity; these feed the two glaciers that 
 (UMbarge into the lake. These two glaciers are the famous Crowfoot and Bow 
 ^ers. (See reproduction page 99.) The former is the smallest and 
 Ti. .t" r ' °f"^»°8 »t8 naine ^rom the form it takes; it enters from the 
 «)utb, the foot of the glacier being within a hundred yards of the lake shore 
 Bow glacier lymg at the west end of the lake is much larger; the foot is one mile 
 from the shore, the intervemng distance being filled up with the debris from the 
 glacier or moraine; over this the creeks from the forefoot find their way 
 
 ; i 
 
 Ahea. 
 
 The lake is approximately 3 miles long, from east to west, and varies from 
 a quarter of a mile to neariy a mile in width. (See reproduction page 98.) 
 The lower portion about 100 acres in extent being 3 feet lower than the upper pttrt 
 and connected with it by a creek of conjiderable width, from 100 to 200 yards 
 wide. The total area of the lake is 800 acres and the area tributary to it roiiehly 
 30 square miles; lying as it does at a comparatively high altitude, the drainage 
 uea IS pecuhar. The surrounding mountains are classed among the high peaks. 
 Bow peak bemg shghtly over 9,000 and the majority over 10,000 feet! Under 
 ^se circumstances, it is to be expected that the run-off will occur to a great 
 extent during the warmer part of the summer. Information as to the time of 
 ice formation on the lake in the fall is not available, nor the approximate date 
 on which the ice leaves the lake.

 Invistioation. 
 
 In the summer of 1911, when a general reconnaissance was made of the 
 Uow basm, m the search for possible storage sites, Bow lake was included. After 
 a general mvestigation of the lake and its surroundings and a rather careful 
 «XMunation of the outlet, it was decided that a survey in greater detail was 
 justified. Accordingly a party was sent up to the lake in August, 1911. Owing 
 to tbe difficulty of transportation, and distance from the nearest base of sut^ 
 pUM, Banff, It was decided not to survey the lake in any great detail but to work 
 up thoroughly the outlet end of the lake.

 A Stadia traverse was run around the lower part of the lake, also around 
 the upper part for part of the distance; the traverse was confined to one side 
 only, points being located at frequent intervals on the opposite side by stadia 
 and triangulation. 
 
 Cross sections were taken of the banks of the lake at every station, with 
 hand level and tape, and the shores of the lake contoured for a height of thirty 
 feet. The outlet end of the lake was worked up in greater detail, a complete 
 atadia survey being made and two dam lines located. In addition a couple of 
 test pits were dug, revealing a very compact boulder clay overlying the rock in 
 the vicinity of the dam site. 
 
 Storage Capacity. 
 
 The accompan>-ing plans were plotted from the surveys made. A study 
 of them revealed the fact that the height to which the water in the lake might 
 be raised was governed by the height of the ridge of land to the north of the 
 lower lake; this is at an elevation above 6,530, but in places drops below that 
 «levation; by building a short embankment, however, the water might be raised 
 to 6,530. This was therefore fixed upon as the upper level of the storage, the 
 lower level bdng the present normal lake level.

 The amount of storage secured by raising the water to elevation 6,530 is 
 27,411 aore-feet, equivalent to a discharge of 466 c.f.8. for one month of thirty- 
 one days. 
 
 SuL'HCEH OF Water Supply. 
 
 The lake is fed from a number of sources, the two principal ones being the 
 Bow and Crowfoot glaciers. The former discharges into the upper lake at the 
 west end; the stream flowing from the glacier varies in size with the tempera- 
 ture; where it enters the lake it breaks up into a number of small streams, 
 which at time of examination would aggregate about 50 c.f.s.; this was visible 
 discharge, but owing to the nature of the underlj'ing material the underflow 
 must bear a large ratio to the surface flow. At the northwest corner of the lake^ 
 a stream, which is the actual source of the Bow river, enters (see reproduction 
 page 102); this rises about 3 miles west of the lake upon the Bow smnmit^ 
 and is for the most part spring fed; it has drainage area for several squarf miles 
 and at the time of examination had u discharge of from 10 to 20 c.f Along 
 the north side of the lake there are a number of small creeks with a flo>s of from 
 2 or 3 c.f.s. to 8 or 10 c.f.s. discharging into the lake; on the south sule there 
 are only two or three streams entering the lake, the principal one coming from 
 the Crowfoot glacier; this had a discharge of 10 to 12 c.f.s. when examined. 
 There is no doubt that springs discharging considerable quantities of water 
 exist, as a nimaber of pot holes of from 10 to 15 feet in depth are filled with water; 
 these stand with the water about 10 feet above the lake level, and from the 
 appearance of the water must receive their supply from an underground source. 
 During the time the surveys oi the lake were made in the latter part of 
 August, the discharge from the lake was between 125 and 150 c.f.s.; earlier in 
 the season this is, no doubt, very much exceeded. 
 
 Process of Filling. 
 
 Measurement of the discharge from the Bow lake have not been made 
 owing to the difficulty of access, and the foregoing figures are based upon 
 estimates made of the diflferent discharges; it is thus impossible to draw up 
 diagrams showitog the process of filling and emptying the proposed reservoir 
 though certain conclusions have been arrived at. 
 
 On the assumption of 27 \11 acre-feet of storage, if the process of filling 
 was commenced May 1 and continued during Jime, July and August, with a 
 constant inflow into the basin, it would require 112 c.f.s. to fill the basin. There 
 is therefore no reason to doubt that there is sufficient rim-off into the lake to 
 provide this amount of storage, and make up the loss due to evaporation. 
 
 ■ Manipulation of Storage. 
 
 One objection to this storage basin, is its distance from the point of utiliza- 
 tion, and in view of what has occurred during the winter of 1912-13, the objection 
 appears to be a good one. 
 
 There is also the question of attendance in connection with regulation 
 and some method of communication; the objection to placing an attendant 
 at the lake, during the winter, is the difficulty of securing a man who would be 
 both suitable and willing to remain at the lake during the entire winter, for at 
 this season it would be difficult to get out and in. If a telephone was placed at 
 the lake, a line would have to be built from Laegan, a distance of nearly 30 
 miles. . J • . 
 
 It is proposed, however, to make special use of this storage; dun;ig the 
 season just mentioned it was necessary to draw on the storage during November 
 und December, and the water would be badly needed during the early sprintr

 monthfl; the idea is, therefore, to release the water from Bow lake during 
 November and December, or March and April, dependmg upon the season, 
 the latter period bemg preferable as conditions are improving and the lews due 
 to ice troubles would be reduced to a minimum. No attempt at regulation 
 would be made, but a uniform discharge over a period of one month could be 
 maintamed. Any necessary regulation could then be made more easily by means 
 of storage in closer proximit j- to the point of u^. By operatmg in this way, the 
 services of an attendant at the dam could be dispensed with, and the loss due 
 to the formation of ice could to a large extent be overcome. 
 
 Assuming that all the water would be released in one month, a contmuous 
 discharge of 466 c.f .s. would be secured at tae lake. In amvmg at the benefats 
 to be derived from storage in the lower river, only a discharge of 400 c.f.s. has 
 been used, it being assumed that the rest is lost between the pomt of storage 
 and the point used. 
 
 Dam. 
 
 The site of the proposed structure is 400 feet downstream from the outlet 
 of the lake. About that distance downstream the river makes a sharp bend to the 
 left, and then again to the right, forming the letter "S." On the right hand 
 side the bank rises steeply for a height of 15 feet, then slopes more gently, rising 
 to an elevation of 35 feet above the water in a distance of 150 feet, where the 
 solid rock is exposed, formmg the banks of the river. On the left side the slope 
 is more gentle, rising gradually from the surface of the stream to a height of 
 35 feet in about 400; the rock is overlaid as on the other side by a glacial deposit 
 of boulder clay; a short distance upstream, on the left side, the rock is exposed, 
 but not at the dam line. The stream at this point is fifty feet wide, and flows 
 over boulders and gravel overlying the solid rock. ,,,,,• 
 
 The bedrock, where exposed on the left side, is a thinly-bedded limestone, 
 and is badly disintegrated (see reproduction page 104). On tlie right 
 hand side this is not the case, the rock exposed being in good condition. 
 
 The structure involved in creating the storage will be a dam 650 feet long, 
 the centre portion of which will be a hollow-type spillway section of concrete 
 provided with sluiceways for dischargmg the water, and also providing tor 
 extra discharge if necessary. 
 
 Spillway. 
 
 The spill section would be placed in the bed of the stream, and from founda- 
 tion to spillway elevation would be between 35 and 40 feet, dependmg upon 
 the depth at which the solid rock lies. The spillway section will be provided 
 with concrete wing walls at each end, and with either a concrete core-wall or 
 steel sleet piling extending through the earth fill section. . 
 
 A provisional section has been prepared for estimatmg purposes, and is 
 shown in the accompanying drawings. It is proposed to place three 4-foot by 
 4-foot sluices in the dam to provide for dischargmg the storage; these will be 
 provided with suitable gates and operating mechanism and will provide for 
 additional discharge should the 100 feet of spillway prove madequate at flood 
 time. This, however, is only a remote possibility as a run-off of 25 c.f.s. per 
 square mile would only give a discharge of 750 c.f. s., while with an overtop of 
 1 foot the spillway would discharge 334 c.f.s. and with 2 feet overtop, 945 c.f.s. 
 
 Embankment. 
 
 At either end of the spillway section, the dam will be inade up of an earth

 In addition to these, it will be necessary to build an embankment opposite 
 the outlet of the upper part of the lake at the point indicated on the plan; this 
 will be 460 feet loi^ and 8 feet hi^h at the highest point. By placing the 
 embankment at this point, water will be prevented from escaping down what is 
 apparently an old bed of the river, lying to the north of the present one, and 
 joining it about a mile-and-a-half downstream. 
 
 CoNSTBUcnoN Difficulties. 
 
 The creation of the storage at this point does not present any engineering 
 difficulties. The greatest difficulty to be overcome is transportation; at present 
 the only means of communication is by pack trail, and though a considerable 
 length of new trail has recently been constructed, the cost to convert it into a 
 wagon road would be prohibitive. Winter transportation seer<8 to be the 
 solution of the difficulty; during the summer all the Bow valley flats below 
 Hector lake are soft, but in the winter, for little outlay, a first-class road could 
 be built. Above Hector lake there are no difficulties to be encountered either 
 in the way of hills or soft spots. Once the bottom was secured, heavy loads 
 could be transported with ease, and the cost should not exceed S8,000 to $10,000 
 at the outside. 
 
 Transportation being secured, the cost of undertaking would be small, 
 supplies being placed on the ground during the wintvr and the work prosecuted 
 dunng the summer. It would be possible, if proper precautions were taken, to 
 place the central portion of the dam during th j winter or low-water period.

 CHAPTER IX. 
 
 ELBOW RIVER. 
 
 General. 
 
 The Elbow river is one of the chief tributaries of the Bow, to which it adds 
 its waters within the limits of the City of Calgary; from source to mouth it 
 is over 60 miles in length. It rises in the eastern slope of the Rookies, the source 
 being near the main continental divide, and it has all the features of a mountain 
 stream. 
 
 The total drainage area of the Elbow river is 482 square miles, about 255 
 square miles of which lie above what may be termed the power-producing 
 section. Near the head of the river, the drainage area is al' ..t a considerable 
 altitude, and, in consequence, the discharge is very susceptible to changes in 
 temperature. The flood period occurs toward the latter end of May and during 
 the month of June, when the flow of the stream is augmented by the water 
 from the melting snow in the mountains. Owing to the steep slope, the run-off 
 is very rapid and the variations in the stream flow very great, due not only to hot 
 weather, but to the sudden heavy rains which occur in the region. 
 
 The river-bed is composed for its entire length of gravel and detritus, espe- 
 cially in the mountain portion, where the gravel overlies the bed rock to con- 
 siderable depths, the latter being exposed only at isolated points. 
 
 These conditions are ideal for underflow, the flattening out of the slope of 
 the stream allowing the water under the slower velocity to sink into the loose 
 material composing the bed. 
 
 Discharge. 
 
 Gaugings have been kept of the Elbow river for a considerable period, and 
 with very few omissions since May, 1908. The station is just above the junction 
 with the Bow river and gives the total discharge of the river; no other gauging 
 station has been established, but miscellaneous meterings have been made at 
 other points on the river. These have, with few exceptions, been made at other 
 than the low water period, consequently it is nearly impossible to arrive at any 
 definite conclusion as to the discharge of the upper part of the river. 
 
 Isolated gaugings were made in the vicinity of Canyon creek during the 
 winter of 1910-11, and may be used as an indication of the probable discharge 
 at that time, though the discharge, due to ice conditions, may vary greatly from 
 day to day or even from hour to hour. The fact that under-flow occurs has 
 a very material bearing on the discharge. This portion of the run-off is not re- 
 corded, but is, nevertheless, available, for the erection of a structure in the 
 stream bed on a solid foundation would intercept all the flow, thus any recorded 
 surface flow must be increased to arrive at th' true discharge of the stream. 
 
 Tables are included giving the discharge of the Elbow river at Calgarj-, 
 also a curve giving the mean monthly discharges has been plotted and is included. 
 (See diagram, Plate No. 4.) The table reveals the fact that the surface flow 
 is at times as low as 100 c.f.s., and may be even lower, though what amount 
 should be added to this to give the combined surface and undertow discharge is 
 rather hard to determine. In March 14, 1911, gaugings were made above and 
 below Canyon creek which was practically dr>'; the results were 92 and 113 c.f.s.

 respectively, or s difference of 21 c.f.B. in two sections 200 feet apart, which m^ 
 be taken as rather conclusive evidence of the presence of underflow. In Feb- 
 ruary, 1911, gaugings were made at the same two points, and gave 138 c.f.s. 
 above and 135 c.f.s. below. Mr. Mitchell, in a report upon the possibilities of 
 power on the Elbow, states that, in his opinion, the underflow may be taken 
 as forming 25 per cent, of the total discharge of the river in the vicinity of Canyon 
 creek: no attempt has been made to verify this opinion by actual measurement, 
 as the construction of a tight weir would be involved, but there seems little 
 reason for disputing it, in fact, quite possibly this figure might be exceeded. 
 
 From the tables and the foregoing estimate of underflow it is concluded 
 that the total mean discharge of the river at Canyon creek wU not he less 
 than say 120 c.f.s. This low flow would extend over the period from Decim- 
 ber 15 to March 15. 
 
 Power Section of River. 
 
 In May, 1911, a reconnaisance of the Elbow river was made and from the ex- 
 amination of the river it was decided that the possibility of producing power 
 was confined to the section lying between the 20- foot falls in section 17, 
 township 22. range 6, west 5th, and the east boundary of section 14, township 
 22. range 6, .-"st 5th. Below Canyon creek for a distance of about 2 milM the 
 river is confined in a narrow valley by banks from 150 to 200 feet high; below 
 this section the fall in the river is less, so nothing would be gained by going 
 below the point indicated. , , . -, xu u 
 
 Between the 20 foot falls and the Canyon creek the river flows through 
 what is practically a continuous canyon. Above the falls the valley is wide 
 and flat and it was hoped that advantage might be taken of the natural fall 
 and the wide valley above for a power site but no feasible dam site exists in the 
 vicinity with banks of sufficient height. There are several possible locations 
 below the falls to which the same applies, but the only one found is at a point 
 a few hundred yards above the mouth of Canyon creek. One site lying above 
 this was examined in detail, which in itself was suitable in every way, but the 
 existence below it of a very high cliff and rock slide on the north side precluded 
 the building of a necessary flume, so that point had to be abandoned. 
 
 The height of the cliffs and adjacent benches determine the height to which 
 the dam, necessary in connection with a flume line, may be built. In any 
 scheme that has been evolved for the development of power on the Elbow, a 
 flume line has been an essential part; the comparatively low discharge neces- 
 sitates a high head development to insure economical development. The gen- 
 eral idea of the development has therefore been, to develop part of the head 
 by a dam and to secure the remainder by carrying the water along the benches 
 to some convenient point and there convey it to the valley, thus utilwing the 
 natural fall in the river below the dam. 
 
 Storaox. 
 
 rhe flat above the 20-foot falls narrows rapidly about 2 miles up the valley, 
 and is co. fined by the high mountains. The river is very steep and rough and 
 at the extreme end issues through a narrow gap between two mountains; here 
 the walls are formed of limestone. „ / j x- 
 
 Just above the gap there is a very wide valley (see reproduction 
 page 107), the whole bottom of which is covered with gravel, and the stream 
 finds its way through this by a number of small channels. The valley is about 
 3 miles long and varies from 1,200 to l,600,feet in width, and with the g»P « the 
 lower endforms an ideal site for storage; this question will be dealt with later.

 PowBB Development. 
 
 5 QEORGE v.. A. 1918 
 
 The study of the situation during reconnaissance leads to the conclusion 
 that there is only one scheme worthy of full consideration. This involves a 
 dam above the Canyon creek, a flume line following the bench lands on the north 
 side of the river, and a power house placed in the river valley about a mile and 
 a half below Canyon creek. In May, 1911, a party was plac^ m the field and 
 this general scheme was developed in detail; a survey was made of the dam site 
 in sufficient detail to admit of preliminary plans and estimates for the struc- 
 ture being made, care being taken to locate all evidence of rock in place and 
 obtain such additional information as might be necessary. The flood line was 
 defined in a general way, the upper limit being located at all vital points. The 
 flume line was located and a contour survey made of the country adjacent to 
 the line including the site of the proposed head-works, penstock line and power- 
 house. This information is all embodied in the accompanying plans. 
 
 PowEB Dam. 
 
 The site of the dam is a few hundred yards above the mouth of Canyon 
 creek where the river flows between two high rock cliffs (see reproduction 
 page 107). The south bank rises to a height of 80 feet above the surface of 
 the riv3r, while on the north side it rises to 90 feet. The bank on the south side 
 slopes back gradually from the top of the cliff, rising to an elevation of several 
 hundred feet, while on the north the height of the banks is about 175 feet, 125 
 to 150 feet of which is rock cliff, a dam at this point would raise the water to a 
 sufficient height to allow it being carried on the bench in a flume. It would also 
 back the water upstream to a point about a quarter of a mile above the 20 foot 
 falls, flooding an area of about 80 acres. 
 
 The lower hundred feet of the dam is not over 250 feet in length. An ap- 
 proximate estimate of the cost of the dam has been r lade and is given. 
 
 Flume and Penstock. 
 
 It is proposed to construct the conduit between the power dam and the 
 forebay or standpip-? above the power station of wooden staves, banded with 
 steel, having a circular section 84 inches in diameter. Such a flume when well 
 built of good timber is tight and efficient and has a life of from fifteen to twenty 
 years, depending on earth and water conditions; it is elastic, easy of transport 
 and construction, offers a minimum frictional loss to flowing water and is above 
 all, economical in first cost and repairs. The total length of flume is about 
 7,500 feet, most of which will be laid in shallow eari" cut on the sides of the 
 gravel benches, and would be subjected to but a few pounds pressure. 
 
 The flume line as located was assumed at an elevation of 4,820, the water 
 surface being 4,840. On this assumption it was run as nearly as possible to 
 grade. It follows along the top of the first bench on the north side of the river, 
 crossing Canyon creek about 150 yards from the mouth, on a trestle. It then 
 keeps up on the second bench at a distance from the river, varymg between 
 two hundred feet and a quarter of a mile. At the lower end of the flume a 
 regulation chamber or forebay is proposed, and leading from it to the power 
 house a penstock (wooden stave pipe) 84 inches diameter and 1,600 feet long, 
 wiU be necessary. The larger diameter is designed to reduce the velocity wid 
 avoid dangerous water hammer in so long a pipe, which would also be fitted with 
 relief valves at the lower end. The penstock would be laid in a trench conform- 
 ing to the general grades of the hillsides and benches and be amply provided 
 with concrete anchorages.

 Owing to the powibility of a rock foundation tliroughout, it may be neces- 
 sary in order to secure a good bond between the foundation and the dam, and 
 to prevent poMible leduge along th« rock surfaces, to build a core wall across 
 the dam site extending 10 to 12 feet up into the dam. _.. ^ , 
 
 The accompanying plans illustrate the layout of the site; an estimate of 
 the probable cost of the work has been prepared and appears in the report. 
 
 Bbnefitb of Storage. 
 
 The available water stored will after due allowance for evaporation and 
 other losses provide for a continuous flow for three months and a half of 80 
 cubic feet per second, which should ensure a contmuous flow of about 200 o.f.s. 
 throughout the year; there is litt'e doubt that the surplus flood water m any 
 season will fill this reservoir. 
 
 Power Developed. 
 
 With a water supply of 200 cubic feet per second and effective working 
 head of 216 feet, about 3,90U horse-power in mechanical energy would be 
 developed after electric generation and transmission, aay withm a radius of 
 10 mileTit would produce an effective commercial power of 3,600 horse-power 
 b dectncal eneror. The foregoing is based throughout on 24-hour service 
 wd is assumed to be the mmimum power of. the year, which occurs during the 
 tfa^ winter months; for the remaining nine months, the electrical output 
 oftheT^t wSld be increased from 3,800 to 4.200 horsepower on peak 
 load by the use of more water, and it is proposed to arrange the equipment of 
 the plfuit so as to produce a maximum of 4,200 horse-power m electrical power 
 delivered within a radius of 10 miles of the plant.

 The Kananaskis lakes are spoken of as the Upper and Lower lakes, on 
 account of a difference in level of about 90 feet, the Upper lake being at elevation 
 5,550 and the Lower at elevation 5,460. The Upper lake is about 2^ miles 
 long and l\i miles wide. The lower is 3 miles long and half-a-mile wide. 
 
 The Upper lake is worthy of special mention from a scenic point of view — 
 it is studded with islands and has snow-capped mountains to form a background, 
 the addition of well-timbered shores and islands forms a picture which rivals 
 in beauty any of the better-known lakes which are to be found in the Rockies. 
 (See reproduction page 117). The stream which joins the Upper and 
 Lower lakes is about 1 mile in length and, as has been noted, drops 90 feet in 
 that distance, the fall being composed of rapids and one abrupt fall of about 
 40 feet. 
 
 The Lower lake, being surrounded by lower-lying hills, and having no 
 islands, presents a less fine appearance than the Upper lake, though it is not 
 without beauty. The fishing in these two lakes is exceUent, and will be an 
 added attraction to the locality when it becomes, as no doubt it will, a resort 
 for tourists. (See reproduction page 118.) 
 
 As far as storage is concerned, the lakes do not offer any desirable site, 
 the outlet of the Upper lake — the only possible point at which the water could 
 be controlled — would require such a long structure placed in water of consider- 
 able depth (from inspection estimated at at least 40 feet) at a cost which, in 
 view of the advantages obtained, is beyond consideration. 
 
 Further, in considering any scheme of storage on this lake, the beauty of 
 the lake in its natural state and the extreme probability of its becoming a 
 summer resort in the near future should not be lost sight of. 
 
 Below the Lower lake for a considerable distance the banks of the valley are 
 far apart, and except at one point about a mile and a half below the outlet of 
 the lake, do not offer a site for control. At this point there is a possible site for 
 a dam, but the fall of the stream is so rapid that at the extreme height of the 
 dam only about 2 feet of storage would be obtainable on the lake, and the 
 structure involved would be six or seven hundrnd feet long on the crest. 
 
 After careful consideration of the physical peculiarities of the locality, it 
 was not thought that a detail survey of the different points in the vicinity was 
 justified, and the possibility of storage at this point was therefore not further 
 considered. 
 
 Kananaskis River. 
 
 The Kananaskis river has a drainage area of 406 square miles between the 
 lakes and the Bow river. It flows through a narrow valley confined by high 
 mountains — the Kananaskis range forming the west boundary, and the Opal 
 range the east. The tributaries are all small and on account of the topography 
 are mountain torrents, being short and steep and carry down lar|^ quantities 
 of gravel and detritus. The valley bottom through which the river flows is, 
 on the whole, wide and flat. Where this is not the case, the river flows between 
 alternating high rocky cliff and gravel and clay banks, the latter being moraines 
 composed of the material transported by the mountain torrent and ancient 
 glaciers. The valley floor is deeply covered with this transported material, 
 through which the nver has cut its way and, where the valley is wide and flat, 
 the river is continually changinK its course, especially during the high-water 
 season. At one point about 4 miles below the Lower lake, a fall about 26 feet 
 high occurs; for the rest of its length, no abrupt drops occur, but the fall is 
 considerable.

 First Assumption. 
 
 The only benefit obtained during the last month of storage being that 
 due to the effect of the eight-hour discharge upon the plants below. The con- 
 tinuous discharge cannot be included since it represents the natural flow of the 
 river and would be utilized under ordinary conditions. This effect may be 
 stated as follows: — 
 
 During the fir!:^ five months of storage the avera^o head at the storage dam 
 may be taken as 45 fct, giving a continuous output . 572 b.h.p. due to a dis- 
 charge of 140 c.f.s. In addition to this there will be an output for eight hours 
 each day of 330 b.h.p., due to a discharge of 81 c.f.s. 
 
 The effect of releasing 81 second-feet from the basin would be to make it 
 .it once available for power production at the three points below the basin at Kan- 
 anaskis falls. Horseshoe falls and the Bow Fort site since the tail-water of one 
 plant is nearly at the same elevation as the head-water of the plant next below. 
 
 The effect upon the fourth site would not be noticed for at least two hours 
 after water wa.s rele.'wed, as there is a stretch of about 8 miles of river between 
 the tail-water of the Bow Fort site and the Mission site; at the next two sites, 
 Ghost and Radnor, the effect would be noticed about the same time or 
 approximately two hours and a half after water was released. If the power from

 By the second method of regulation the output on peak load from auxiliary 
 stonwe would be 4,700,096 horse-power hours. 
 
 By the first method the contmuous output of power would be reduced by 
 907,200 horse-power hours and by the second increased about one-half of that 
 amount, or 383,000 horse-power hours. If the peak loads are high, then the 
 second method of r^:ulation would be the most advantageous. If the load is 
 nearly uniform, then the reverse is the case. 
 
 No definite conclusions can be drawn with regard to the economic side of 
 the question without knowing the load conditions on the plants. An attempt 
 has been made, however, to arrive at the probable cost of the power produced 
 by the use of this basin. The cost deduced is in terms of kilowatt hours, ♦"

 HECTOR LAKE. 
 
 if 
 
 In July, 1911, a reconnaisaance was made of the upper part of the Bow 
 river, to determine the poaaibilities of storage in that seotton of the river. The 
 expectation was that either or both the lakes, Hector and Bow, forming the 
 source of the Bow river, might be utilised. Bow lake at the source was proved 
 to be suitable, and is dealt with in another part of the report; on the other 
 hand, Hector lake was foimd to be unsuitable for storage purposes. (See 
 reproduction page 127). 
 
 Hector lake lies in a hollow formed between a number of high peaks; to 
 the west lie mounts Gordon, Balfour and Olive, of altitudes 10,336, 10,731 and 
 10,260 feet, respectively, all glacier-hung peaks. To the south is Pulpit peLk, 
 of an fdevation 6,930, and to the north Bes Bow peak. 
 
 'liector UJie is fed from the glaciers to the west, and also from two small 
 lal 4i to the south that lie at high altitudes— the upper one, Turquoise lake, at 
 an elevation of 6,975 feet, and Miurfaret lake at an elevation of 5,906; the upjper 
 lake empties into the lower, and this in turn into Hector lake; to the north is a 
 stream coming down on the south side of Bow peak. 
 
 The lake is about 3^ miles long, and three-quarters of a mile mde, it lies 
 about 15 miles by tibte nver above Lauan and at an elevation (rf 6^700 feet 
 above sea-level, or upwards of 600 feet higher than Lag^an. The lake is to the 
 west of the river, about three-quarters of a mile, and u connected with it by 
 two streams which form the outlet; the intervening land had the appearance 
 of having been deposited there in past ages by the river in the form oi a bar. 
 Apparentiy the lake at one time formed a great enlargement of the river and 
 was probably, at the same time, to a great extent covered by the ice from the 
 glacier to the west. This glacier is known as Balfour glacier and is formed by 
 tiie imm^se snow fields which cap the summit of the main divide at this point, 
 and which also feed the Bow glacier. As the glacier receded, the bed of the 
 present lake was Itft, the east end bdng separated from the river by the material 
 deposited, as has been said. 
 
 This barrier, as it may be called, ib about three-quarters of a mile wide, 
 and about the same length, parallel to the river, rising to an elevation of several 
 feet above the level of the lake, and any structure to impound water in the lake 
 would hp- 3 to be of great length in order to rabe the lake level any considerable 
 height; the material is loose and in places very swampy. The lake could not 
 be considered, therefore, as a storage basin either from the engineering or 
 economic standpoint. 
 
 PIPESTONE CREEK. 
 
 The Pipestone creek is one of the largest tributaries of the Bow river, 
 entering above Banff. It has a drainage area of about 160 square miles, which 
 is comparable with that of the main river above their junction, tHir confluence 
 is about half a mile below Laggan station on the Canadian Paciuc railway. 
 
 Discharge. 
 
 At the junction point with the main river a gauging station has been 
 ♦•"^-blished at the instance of the Water Power Branch. 
 
 The discharge of the Pipestone, as measured at the entrance of the Bow, 
 T a considerable portion of the discharge of the Bow at that point. From 
 
 records available the discbarge of the Pipestone may be taken as forming one- 
 third of the discharge of the Bow below their junction during high water; 
 during the normal period the proportion is irreater; while at the low-water 
 period, it forms nearly one-half of the total discharge. 
 
BOW RIVER POWER A«D STORAQE 
 
 125 
 
 SESSIONAL PAPER No. 25* 
 
 The records extend over only a very brief period (since September, 191 1)» 
 so that no definite conclusion can be drawn as to the relative discharges of the 
 two streinns, but the vailable records are, however, included and may prove 
 of interest. 
 
 Drainage Area. 
 
 The drainage area of the Pipestone is very similar in character to that of 
 the Bow above Laggan, the same mountains forming a considerable proportion 
 of the drainage area of each. Their sources lie at considerable altitude, the 
 great difference oetween the tv/o being that while the Bow has two lakes as its 
 source the Pipestone has no lake to act as a regulator of run-off. Strangely 
 enough, this difference has apparently the opposite effect to that to be expected, 
 for the variation between high and low water on the Pipestone is, from the 
 records available, appar y less than upon the Bow. 
 
 The Pipestone from source to mouth is about 22 mik - long. It rises at an 
 altitude of 8,364, and is fed by numerous small streams coming down the 
 ir.ountains, such as Molar eieek from mount Molar and from Cataract peak. 
 The descent of this creek is very rapid, reaching an altitude at the junction 
 with the Little Pipestone of 5,860, a fall of 2,500 feet in about 11 miles, or 257 
 feet per mile. For the next 6 miles the fall is 360 feet, or 60 feet per mile, and 
 for the remainder of its length, about 110 feet per mile. The largest creek 
 entering the Pipestone is that known as the Little Pipestone, which enters *rom 
 the east, and is about 8 miles long, having as its source several sma? "'.es, 
 which lie at between 6,500 and 7,000 feet above sea-level. It drains the northern 
 slope of mounts Richardson and Ptarmigan, which are both over 10,000 feet 
 high and glacier hung. 
 
 Possibility or Storage. 
 
 A reconnaiosance of the Pipestone with a view to storage was made in July, 
 1912, and at the same time the head-waters of Corral creek and Baker creek 
 were examined. 
 
 On the Pipestone it was found that for the first few miles the river was 
 very rapid, the fall of 110 feet per mile being exceeded in places. The stream 
 is confined to a comparatively narrow valley by high steep banks of what might 
 be termed glacial drift, which overlies the rock to a considerable depth; this, in 
 conjunction with the rapiditj' of fall, is not favourable for the storage of anj 
 considerable volume — such as would warrant construction. Higher up, the 
 valley widens into a large flat, which on examination showed that no suitable 
 site for a dam offered itself, and that the slope of the valley was so great that in 
 any event a high structure would be required to flood the valley for any distance 
 upstream. 
 
 Above the junction of the Little Pipestone the character of the valley 
 changes, becoming narrower and much steeper; after careful examination it 
 proved as disappointing as the lower portion of the river, and in consequence 
 the only possible conclusion was that storage on the Pipestone is not possible, 
 and no further work upon it was warranted. 
 
 BAKER CREEK. 
 
 At the same time as the reconnaissance of Pipestone creek the trip was 
 made to include Baker creek, which is the next important stream to enter the 
 Bow below Laggan. 
 
 Drainage Area. 
 
 This creek enters the Bow from the north about 8 miles from the mouth of 
 the Pipestone; it is about 15 miles long and has ii drainage area of 52.8 square 
 miles, about one-third the area of the Pipestone drainage basin. L^nlike the

 Pipestone, it has two Iskes at the source of the main branch, whilst another 
 lace forms the source of the second branch; these lakes are among the highest in 
 the country, the lower of the two first— Baker lake — being at an elevation 
 7,280 feet above sea-level, and the higher— Ptarmigan lake— at an elevation, of 
 7,M1 feet; and lake Redoubt, which forms the source of one of the branches, 
 is the highest, at an elevation of 8,000 feet. The elevation at the mouth of the 
 river is 4,869, so it will be seen that the fall is very rapid: from Ptarmigan lake 
 to Baker lake the fall is 331 feet in less than a mile, and from Baker lake to the 
 mouth of that river the fall is 2,371 feet, being 1,230 feet in the first 3 miles 
 below Baker lake, or 410 feet per mile, and from there to the mouth the fall 
 averages 142 feet per mile. 
 
 DiBCHABOE. 
 
 The dischaige of Baker creek has uot been measured systematically, no 
 gauging station has been established upon it and any records of its discharge 
 that may exist are not available. An estimate of the discharge might be made 
 from a cor parison of the sise of the drainage area and a study on the ground 
 of the Pipestone and Baker creeks, assuming a run-off one-half that of the 
 Pipestone. The existence of three lakes at the source of Baker creek would be 
 expected to have some influence upon the regulation of the flow, but this 
 regulation cannot be very marked on account of the formation of the outlets of 
 the lakes. 
 
 Storage Pobbibilitieb. 
 
 After a study of the maps, and a consideration of the evidence gathered 
 from men familiar with the country as to the physical features of the valley 
 of Baker creek, it was considered that any possibility of storage lay ''u one or 
 all of the lakes which were to be found at the head of the creek and that any 
 study should be made at the upper part; this was done. 
 
 Baker lake was the first one visited. As before stated, it lies in a ocky 
 basin at an elevation of 7,230, is about three-quarters of a mile long from east 
 to west, and about one-fifth of a mile wide. On the north side the shoulder of 
 Fo;wil mountain slopes down to the water's edge, while to the south is Fallen 
 mountain. The lake is confined in its bed by a long, low rock ridge, which 
 extends across the east or outlet end, this ridge is very low, rising only a few 
 feet above the lake level for the greater part of its length, and falling away very 
 rapidly on the downstream side. The situation is not favourable for storage, 
 the area that might be developed by a structure at the lower end being small, 
 and, owing to the topography, any structure would be of great length. (See 
 reproduction, page 128.) 
 
 The upper, or Ptarmigan lake, about a mile to the west, is somewhat smaller 
 than Baker lake, into which it empties, and is very similarly situated. From 
 the outlet, the descent is very rapid, falling in a series of cascades; the outlet 
 is over a low ridge, and presents the same difficulties to storage as does Baker 
 lake. 
 
 Redoubt lake lies to the south of the west end of Ptarmigan lake, and as 
 has been point"'! out, is about 500 feet higher. The waters from Redoubt lake 
 do not enter Baker creek through Ptarmigan and Baker lakes, but 11 rough 
 a valley extending to the east from the shore of the lake. The descent of this 
 creek is extremely rapid, it is less than 3 miles in length, yet in that distance 
 it has a total fall of over 2,100 feet, from tt ee "o five hundred feet of this 
 fall occu'rs at, or near, the outlet, and in this respect the lake is the most pecu- 
 liar of the three. This lake is situated on a shelf of rock, on the shoulder of 
 mount Redoubt, and on account of its situation (resembling a saucer upon 
 a shelf) very little variation in level can occur. A rise of less than 2 feet 
 
aOW KITER POWER AND 8T0KA0M MT

 would give a •piliway of at least 300 feet in lent. a,wlule auy reduction below 
 that level prevents run-off, as apparently the only outlet is over the ridge 
 ' M V Pecuhanty, taken m conjunction with its site, about one-half-a- 
 
 nule by rae eighth of a mile, places it out of the question for storage. 
 
 •1-* * "^*»o'» to the physical features of the lakes, their e:rtreme altitude 
 nulitatefl their use as storage basins unless they could be utilised during the 
 early faU to augment the flow; in the spring they would be useless, because 
 by the time their waters, stored from the previous year, were available, the 
 noods would have set m and discharge from storage would be unnecessary. 
 
 The idea of using the lakes and Baker creek for storage purposes had there- 
 fore to be abandoned. -« *- r 
 
 JOHNSON CREEK. 
 
 Johnson creek, a stream of considerable sise enterbg from the north, adds 
 rts waters to the Bow river about 3^ miles below Castle station on the Canadian 
 Pacific railway. It is about the same length as Baker creek. The head-waters 
 are at considerable altitude, one branch rismg at 8,000 feet, and the area drained 
 is 49 square miles. The mountains to be found in the basin, however, are not 
 generally so high as those to be found iu the Baker basm ; in the matter of glaciers, 
 too. It resembles Baker creek, there being none in either area. Given, then, the 
 8a™e general characteristics in the matter of altitude, area, etc., the run-off 
 should be expected to be nearly the same, then- dramage areas being so close 
 to one another. In the matter of lakes, the resemblance is not so marked, only 
 one occurrmg on Johnson creek. 
 
 For the upper 6 miles of the creek, the fall is 2,000 feet, or 333 feet per mile, 
 below this the fall averages about 170 feet per mile down to the mouth, the 
 total fall bemg 3,367 feet. About 8 miles from the mouth a small lake empties 
 Its waters mto the main creek; this lake is about one-quarter of a mile to the 
 west and almost 500 feet above the bed of the stream.

 Discharge. 
 
 No data are n -ailable regarding the discharge of Johnson creek, though it is 
 understood that s' ne isolated gaugings were made of the creek during the last 
 season, it might, however, be assumed that it would bear the same relation 
 to the discharge of the Pipestone as Baker creek does, approximately one-half 
 to one-third that of the former stream might be a fair estimate.

 Storage Possibilities. 
 
 Photo by M. «'. Hindry. 
 
 In Augaxt. 1912, an investigaticm of this creek was made, in order to dcter- 
 iniiic whether .storage of any extent might 1m '^veloped upon it. It was known 
 tliat a deep and narrow canyon existed where tlie stream made its exit between 
 the sluniMer of Castle mountain and the Sawback range (see reproduction, 
 page 131) an«l that a valley of some cdjisiderable extent lay at theui)per end of the 
 canyon. An examination" pntved this to be so. Access to the valley is gained 
 by means of a trail which leads up the west side of the creek, and lies well up on 
 the outlying shoulder of Castle mountain, (hi account of the depth and narrow- 
 ness of the canyon, the trail swings up, as the latter is neared, then following 
 parallel to it, it finally turns abruptly down until it strikes the rim of the canyon 
 proper, along which it lies for nearly one-half mile until the latter widens out when 
 the t-ail drops down into the valley so formed. This canyon is the deepest encoun- 
 tered in the area lovered bv the inve.stigati<ms, it is approximately three-quarters 
 of a mile long, a-id at one point must be from (MM) to 700 feet deep an<l at the top 
 not over that in width at t lu' narrowest point; the accompanying reprwluctions 
 illustrate the nature of this canyon fairly well. The valley behind tlie cany<m 
 is rather limited in extent, and d(M's not widen out suddenly at the mouth of the 
 fjinyon, but oxtends for ne.-irly one-quarter of a mile liefore the widest point is 
 reached where it is not over one-third of a mile wide. The valley floor is narrow, 
 rising i<i a seri<'s of benches on either sith-; it is about one mile long, and then

 narrows, the stream having banks from ten to twenty feet high, l)aek of wliicli 
 are a series of terraces. As was shown earlier, the valley slope is very steep, 
 especially where the stream enters the canyon, and in order to flood the valley 
 even for one mile upstream a structure at least 200 feet in height would be 
 required; this in the liglit of the restricted area that would be flooded would 
 involve a cost that could not be considered. 
 
 VERMILION AND REDEARTH CREEKS. 
 
 These two creeks enter the Bow river from the south, Vermilion about 1 
 mile west of Castle, where the new motor road, which will eventually cross the 
 Rockies, crosses the Bow river from the nortli to the south side. The Redearth 
 enters about 5}^ miles below the Vermilion, antl from the same side. 
 
 Both these creeks are very short and their slopes abrupt, the former falls 
 1,550 feet in 7 miles, or 220 feet per mile, and the latter averages 200 feet per 
 mile. 
 
 A careful inquiry wivs made into the natural conditions antl considerable 
 inforniation gathered from men thoroughly familiar with the country. Owing 
 to the inaccessibility of the streams, especially Re<learth, it was not considered 
 that an examination was necessary, the conclusion l>eing reached that they were 
 not adapted to storage. 
 
 BREWSTER CREEK. 
 
 The waters of Brew.ster creek an<l Healey cr^-ek combined enter the Bow 
 river about 'iV> miles west of Banff; the flow is of fair magnitude, though no 
 gauging has been made of the stream. 
 
 Ji*«t above the mouth where it issues into the bottom of Bow valley, it 
 spreads itself over a gravel flat and is divided into a number of small streams, 
 each of which finds its way to the main river, an<l on this account cannot have 
 any marked effect upon the winter flow of that river. Brewster creek, like all thi' 
 other creeks that have been examined, has an excecsive shfe fr( m nuice to 
 mouth; it is not as steep, however, as the ot'.ers, l.avi ig an average fall of 100 
 feet per mile.

 GHOST RIVER. 
 
 11^ 
 
 
 The Ghost river, which enters the Bow on the north side at a point about 
 35 miles west of Calgary, is 40 miles long from source to mouth, and has a drain- 
 Age area of 367 square miles. Eight mUes from the mouth, the stream divides 
 into two branches, known as the Main branch and the North Fork. At a point 
 7 miles farther the main stream divides again, one branch retaining the name 
 Ghost river, and the other being known as the South Fork. 
 
 The sources of these three branches are at about the same altitude, 8,000 
 feet above the sea-level. The South Fork rises on the east t-->pe of the Fairholm 
 range, and issues through the gap formed by End mountain and Saddle peak 
 into the foot-hill country, and in a distance of 8 miles falls 2,000 feet, or 250 
 feet per mile. The main branch of the Ghost rises on the north side of the 
 Palliser range, of which Cascade mountain is the easterly end, it flows around 
 to the north of mount Aylmer, to the south side of Devil's Head, and out into the 
 foot-hills. The fall of this part of the Main branch is not as steep as that of 
 the South Fork, being approximately 133 feet per mile; the valley through which 
 it flows is wide, and covered with gravel and the debris carried down by the 
 mountain torrents which are tributary to it. The North Fork rises on the 
 eastern slope of Castle Rock; it has a less steep slope than the others, and is for 
 the most part in the foot-hills; it has numerous tributaries, which rise in the 
 swamps and sloughs to be foun i m the territory through which it flows. 
 
 Discharge. 
 
 Discharge records of the Ghost river have been kept since August, 1917 
 The gauging station, which was established at the instance of the Water Powt 
 Branch, is at the highway bridge which crosses the river about 200 yards from 
 the mouth, and the gauge rod is placed about 1 mile upstream. The available 
 records cover only one year, the readings were unfortunately interrupted for 
 a period during November and December, no data being available for a month 
 during the low-water; good records were obtained, however, for January, 
 February, March and April. The mean flow for that part of November avail- 
 able shows a flow of 219 c.f.s., with 191 c.f.s. as the minimum, so that it may be 
 assumed that a flow of approximately 100 c.f.s. is available during the period 
 of low-water. The available records of run-off will be found elsewhere in the 
 
 The greater part of the area drained by the Ghost river lies in the foot- 
 hills' it is reasonable to expect, therefore, that the discharge will be more 
 susceptible to the direct influence of rain and snowfall. An examination of 
 the data reveals the fact that the flood period is earlier than on the other streams, 
 making its appearance in April and May, and that the precipitation during the 
 fall instead of being stored as it would be in the higher altitudes, is apparently 
 discharged to a great extent at once, or being at a lower altitude is melted and 
 runs off The run-off during September and October is comparable to that of 
 May and June, while from the records the run-off during August appears to 
 be even greater. 
 
 Storage Possibilities. 
 
 The slope of the stream is so steep in the mountain portion that the develop- 
 ment of any storage in that section was at once discarded as improbable, and 
 attention was given to the section to be found in the foot-hills. The South Fork 
 and the Main branch both, particularly the portion between the junction with 
 the South Fork and the junction with the North Fork, flow through vnlleys 
 that are comparatively wide, varying from a couple of hundred to a thousand 
 feet in width. During low and normal periods, the river spreads all over the

 valley; in many places the river is split up into a number of small streams, 
 WhHili flow all over t^e gravd. bed of the river. The whole floor of the valley 
 is covered to a con4d«nUe depth with the gravel and d^ritus Q^ed down by 
 the river during ^h water, at which time the river covers the whole valley. 
 (See rtmroduction,. iMkge 12). ,^ ^ ^^ ^ 
 
 The banks are for the most part high, rising from 50 to between 100 and 
 200 feet, the rise for the first hundred feet being rather abrupt, after which it 
 is mor? gradual. In the part between the two banks very little bottom land 
 exists, the river occupying the whole of the valley bottom. The south side of 
 the valley is mostly lonned of rockv cliffs, overlaid with gravel and glacial 
 drift, and affording very few points of access to the river valley, from the north 
 side the river may be reached in many places. The first point encountered 
 where storage mu^t be developed, was just west of the junction of the Main 
 branch and the Nwth Fork; here the banks of the valley approach each other, 
 and the river flows through a narrow canyon, the south bank of which rises to 
 a considerable height, but the north does not rise more than 50 feet above the 
 nater level. The rock forms a cliff on either side and extends across the river 
 forming a bar, on the upstream side a conriderable quantity of gravel has been 
 deposited, the water drops about 2 feet in 50 at this point, a drop of nearly a foot 
 occurring where it passes over the bar. The limiting feature of any storage 
 scheme at this point is the height of the rock on the north side; approximately 
 45 feet above the present water level would be the limiting height to which the 
 water could be raised. Considerable fall in the water level exists at the entrance 
 to this canyon, so that 40 feet would probably be the depth that could be 
 obtained in the valley at the mouth, and the rise in the river would not admr" 
 of backing the water up for more than a mile, with a structure of this height. 
 The r<torage provided under these circumstances would be of little use from a 
 power standpoint, except as an auxiliary storage to take care of fluctuations 
 due to changes of temperature. Any storage created on the Ghost would only 
 affect the plants below the junction with the Bow, and these would be benefited 
 within a few hours of the release of the water from the storage. 
 
 As the necessity for such stora^i is somewhat remote, nothing more than 
 a reconnaissance was mp ' of the site. A detail survey might prove the scheme 
 to be out of the que' a. 
 
 On the Nort' . ork, the Eau Claire Lumber Company have bmlt a small 
 timber dam near section 29, township 27, range 7, to store water for driving 
 purposes when the river is low, but just how large this storage is, is not known. 
 It is also understood that they are contemplating changing the site for one 
 higher up stream where more water may be impounded. It is not likely that 
 these basins will store any large amount of water; besides which, they are rather 
 remote for close regulation. It is understood that the basin no\- used may be 
 filled in a few hours when the flow is normal. , . , „ 
 
 Below the junction of the North Fork with the Main river, the valley 
 is not neariy so wide as above, the banks are steeper, especially on the MUth 
 side. From a point in section 5, township 27, range 6, to the mouth of the 
 river, the river winds from side to side on the valley and the banks alternate 
 as high rocky cliffs and steep gravel banks, and the valley becomes deeper and 
 narrower as the mouth is approached; the slone of the river for the last 5 miles 
 from the mouth averaging a little under 40 feet per mile. 
 
 Reoulation Storage Basin. 
 
 Two miles from the mouth, the river passes through a narrow gap in the 
 rock formati."., the hanks are nearly 300 fe^t high, while thr width at wat«r level 
 is not more than 125 feet, and at an elevation of 80 feet above water level the 
 width is only 200 feet. While working on the Bow river the work of necessity

 SESSIONAL PAPER No. 25e 
 
 extended nearly to this point, and a very rapid plane-table survey of the river 
 valley upstream for a distance of 3 miles was made and tied into the Bow river 
 work. This survey has not developed anything attractive, but it illustrates 
 the nature of this stretch of the Ghost river. Rough computations were made 
 of the storage capacity at this point, based upon dSferent-sized structures, and 
 even with a structure 100 feet high the amount of water impounded is only 
 4,300 acre-feet, while the cost of securing this places it out of the question. 
 
 From the foregoing it will be seen that storage upon the Ghost is not a very 
 attractive proposition, though it might be considered advisable at some future 
 time to create a basin capable of storing say 4,000 acre-feet for purposes of close 
 regulation of power plants on the Bow (say at the mouth of the Ghost, and at 
 Radnor), similar to that proposed for the Kananaskis river; any greater storage 
 on the Ghost could not be considered.

 The cnmpariBon of coets is comparatively favourable to the Bow river 
 storage; the ultimate basis upon which the whole project must be judged how- 
 ever, 18 the actual benefit to be reaped by the power producers u^on the part 
 of the river affected by storage, and the mcreased amount of power which mav be 
 produced at the undeveloped sites. 
 
 Review of Situation. 
 
 Before going into these benefits, the general question of storage will be 
 reviewed. As has been emphasized before, the lack of continuous records of 
 nin-off over any considerable period renders positive conclusions impossible but 
 It is c-nsidered that those reached, regarding discharge under low-water 'con- 
 ditions, ."re reasonably correct. After a caref'il investigation and a study of the 
 run-off and meteorological data available, together with a knowledge of the 
 physical conditions obtaining throughout the year, it has been found that the 
 mean monthly flow at Horseshoe falls during the period recorded does not fall 
 i.1 I^ ^i'^-' i^^^ s^^oJ"* periods, perhaps a single day, the flow has dropped 
 below 600 c.f.s.; but the mean monthly flow upon which the storage scheme must 
 be worked out is as above. The lowest average mean monthly flow for the 
 period 1909-12 was 833 c.f.s, and occurred in the low-water season 1911-12 
 The benefits to be derived from storage has been worked out upon the basis 
 of mean monthly flow, and what is felt to be a fair allowance has been made 
 for loss due to evaporation and wastage between the point of storage and the 
 point of utilization. » «»"" '•"c 
 
 Diagrams. 
 
 Diagrams have been prepared showmg the effect of storage upon the flow 
 at Horseshoe falls. The effect of storage from Minnewanka lake, for the low- 
 water period 1909-13, may be seen on the diagram, Plate No. 9; the effect of 
 storage from Spray and Bow lakes for the same periods is shown by diaerams 
 Plates Nob. l."} and 16 respectively. o > 
 
 On the Minnewanka diagram are two lines, the lower shows the 
 effect of the 44,000 ac.-feet available at 12 foot storage (the odd 700 feet is 
 deducted to allow for waste), while the upper s^ .*s the effect of the 
 16-foot storage obtamed by drawing the lake down to its original level

 flow of the river at .-seshoe falls (see diagram, Plate No. 17) has 
 also been prepared. is is based upon a storage capacity of 257,300 
 
 acre-feet, and after «ing for losses it is considered that 245,200 acre-feet 
 will be available , „■ ugmenting the minimum flow; the diagram is based upon 
 the mean monthly flows and is for the period 1909-12, and was compiled from 
 tables Nos. 21, 22 and 23. which are based upon the run-off data for the low 
 water seasons of 190&.10, 1910-11, 1911-12, and show the effect of storage upon 
 the discharge of the Bow river at Kananaskis falls. It will bo seen that at the 
 lowest season discharge of 1,500 second-feet can be secured.

 In preparing the tables Nos. 21, 22, 23, the effect to be obtained from 
 storage js taken as that due to a discharge of 160,000 acre-feet from the proposed 
 bpray basm, 27,000 acre-feet from the Bow lake basin and 44,000 acre-feet from 
 lake Mmnewanka. In addition to this, there can be made available at lake

 charges, ranging from 800 c.f.s. to 1.500 c.f.s. At the bottom of each column

 For the low-water period 1909-10, the mean discharge for the period for an 
 average month i.s 1,025 c.f.s. With this as a basis, from the table -e find that 
 providing for a flow of 1,500 c.f.s. over the low-water period, November to April 
 inclusive, there wi 1 be a surplus of 60,938 acre-feet, without making use of the 
 extra storage available m Minnewanka, or including 14,200 acre-feet auxiliarv 
 storage, a total of 75,138 acre-feet, sufficient to provide for a flow of 1705 c f s 
 over the whole period. « i ■. . 
 
 For the low-water period 1910-11, the mean discharge is 1.124 c f s over the 
 wlH.le period. As before, providing for a continuous flow of 1,500 c.f.s 'over this 
 period, there IS a surplus (omitting as before the auxiliarv .storage) of 75 545 
 acre-feet, or includmg the 14,200 acre-feet auxiliarv storage a total of 89*745

 power years. With the proposed regulated flow this could be increased by 
 1,863 horse-power years, giving a total annual output of 9,964 horse-power 
 years. 
 
 For the Horseshoe Falls plant the same curve applies, the head and regu- 
 lated flow being the same. Here, however, the turbine installation is greater, 
 being 19,500 horse-power from the curve, it will be seen that the total annual 
 output due to the natural flow would be 12,087 horse-power years, to which 
 may be added, due to stream regulation, 2,171 horse-power years, giving the 
 total annual output of 14,258 horse-power years. 
 
 The other curves for the undeveloped sites are worked out on the same 
 basis and the results are tabulated in table No. 5 so that further explanation 
 is hardly necessary. 
 
 Auxiliary Storage. 
 
 Where the main storage basins are so remote from the point of utilization 
 as in the Bow basin, some auxiliary storage of sufficient capacity to tide the plant 
 over a sudden drop in the flow is necessary. The amount of storage that may 
 be developed in connection with each plant is rather limited, the river is con- 
 fined mainly between high banks so that any increase in level produces a very 
 small increase in area; this is especially the case at the present plant at Horse- 
 shoe falls; from the dam to the foot of Kananaskis falls the banks are high and the 
 present flooded area is but little in excess of the former area of the river. 
 
 At Horseshoe falls the area of the pond above the plant is 98 . 5 acres which, 
 with a draw down of 4 feet, has a capacity of 394 acre-feet, capable of support- 
 ing a discharge of 200 second-feet for twenty-four hours; this might be suf- 
 ficient over a short period, but is of little value when a reduction of flow takes 
 place. At such a time it becomes necessary to sustain the flow for the eighteen 
 to twenty-four hours which must elapse before the effect of storage above can 
 be felt. 
 
 The Horseshoe Falls plant is, of all the developments built or proposed, 
 the least favourably situated in this regard. The plant at present building at 
 Kananaskis, though better situated, has very little advantage in respect to 
 storage area. When the elevations of the structure are finally settled, the 
 depth of storage possible may be found to be in excess of that at the Horseshoe 
 Falls plant, but with a draw down of 4 feet as before, and a pond area above 
 the dam of 122.25 acres, a total of 489 acre-feet would be available; this would 
 provide a flow of 258 second-feet for twenty-four hours. 
 
 The drawing down of the head-water, however, makes a serious inroad 
 upon the output of the plant; the storage propositions looked into on the 
 Kananaskis river within a radius of 8 or 10 miles of Kananaskis falls have been 
 made with a view to eliminating this trouble as much as possible. 
 
 An examination was made of the Kananaskis river during the summer of 
 1912, to investigate the possibility of creating storage in lake Chiniki by damming 
 the river and raising the water to a sufficient height to flow into the lake, to be 
 there stored until needed. It was found that it would be necessary to go a long 
 way upstream to raise the water to the desired height, and also that to return 
 the water to the river it would be necessary to re-traverse or cut through a 
 height of land between the lake and the river; this would involve considerable 
 work, as the summit, though not high, is long. 
 
 There are several possible dam sites within a distance of 8 miles from the 
 mouth of the river, at which the water might be raised 40 or 50 feet; the amount 
 of storage these would create would be small, and only a survey in detail would 
 reveal the value of the several basins so created; these were dealt with before. 
 
 The other proposed developments are rather better situated than the 
 present two, the area of the ponds at these several sites are as follows: —

 In connection with the Ghost and Radnor sites, the question of storage 
 on the Ghost nver was looked into. A possible storage basin of small area near 
 the mouth of the nver, and of which plans accompany this report, was developed 
 in some detail; the site, however, is not considered attractive as the capacity 
 tor storage is limited and the structure involved large. 
 
 Ice Conditions below Storage Basins. 
 
 Ra„«^* the end of last winter an examination was made of the river between 
 a^f.r Kananaskis falls; also of the Cascade river between lake Minnewanka 
 and the mouth, and the Spray nver for about 8 miles from the mouth A 
 number of photographs were taken to iUustrate ice conditions found at different 
 points on the nvers, some of these are reproduced here. 
 
 Between Kananaskis falls and the mouth of the Cascade the Bow. when 
 
 .T.Ti ' """ «°,' *HS''''i P*'* ?Rf°' ""•* '° " ^""^ Pl*"*" o»ly «^-« there evidence 
 of overflow. Below the Spray fa Is on the Bow, where the formation of fra«il 
 W(m!d be excessive, there was httle evidence of clogging and overflow the river 
 bemg entirely confined to the channels. On the Spray river, asTar rT^S 
 the same conditK'>s obtained; for the first 4 miles above the mouth, SfS 
 was entirely ice U.und, above that point the river was open in many p aces, and. 
 although some overflow had occurred, the nmount was so small that it was 
 practically neghgible. >■»•»» 
 
 On the Cascade, the conditions encountered were somewhat different 
 Between the storage dam and Bankhead, the river was practically clear of ice." 
 and there was no evidence of the formation of any large quantity. This con- 
 dition showed a reversal of the conditions found in March, 1912, for after a 
 certain amount of water had l>een discharged from the lake in 1913, large quan-

 The comparative remoteness of the several storage basins from the power- 
 producing sections of the river, prevents any close regulation of the flow at the 
 planta, for it is estimated that it will take at least 18 hours before water released 
 from Minnewanka will reach Kananaskis Falls. 
 
 During the last winter, owing to the difficulty of anticipating temperature 
 changes (the controlling factor), water released from Minnewanka did not reach 
 the plant until the extreme conditions due to the weather had partially adjusted 
 themselves; also, a large percentage of the water was wasted in transit, especially 
 in the upper part of the river near the basin, in the form of ice. It is scarcely 
 fair, however, to use the first season of regulation as a basis for reaching definite 
 conclusions as to the benefits to be secured, for it must be remembered that, 
 besides lack of experience in handling the storage, other things militated against 
 maximimi efficiency; for instance, between Bankhead and the mouth of the 
 Cascade, no improvement to the river bed has been made, thus much of the 
 water released spreads over the flats, freezes and is wasted. 
 
 Diagram, Plate No. 3 shows not only the marked influence of temperature 
 upon discharge, but also shows when and to what extent storage was supplied, 
 for the recorded levels indicate the discharge indirectly; it may safely be assumed 
 that when the surface level remains constant there is no discharge, and when the 
 lake level falls, water is being discharged from storage; also the rate of decrease 
 in the lake level indicates the rate of discharge. 
 
 The wasting of water by ice formation on the flats, as mentioned above, is 
 due, in a very great measure, to the method of storage manipulation. 
 
 A study of other rivers in the vicinity during the past season has led to the 
 conclusion that if the channel is kept open, little clogging and overflow occur. 
 
 It will be noted in nearly every case, that for a varying length of time, 
 immediately preceding a period of low temperature, and during the first part 
 of that period, the flow from storage was that of the normal flow of the river. 
 Later, the water released from storage met with a condition in the river, a 
 channel restricted and clogged with ice, the result being an overflow and 
 excessive ice formation in the river valley. 
 
 The opinion is advanced that, under the normal conditions of the river, or 
 where the normal discharge is fairly large and constant the ice troubles will be 
 ve-.y appreciably reduced. 
 
 It is therefore expected that, with the building of a power plant upon the 
 Cascade, immediately below the storage dam, and the consequent nearly con- 
 stant discharge, the channel will be kept in fair condition, which will go far to 
 eliminate the trouble. 
 
 The discharge from Spray Lake basins will take even longer to reach the 
 plants, so that any attempt at regulation would Le of httle benefit; it is therefore 
 proposed in regard to that basin to keep the flow fairly constant during the low 
 water period, and do any necessary regulation near the plants. 
 
 A fairiy large flow or discharge from Spray lakes will, ii is expected, elimin- 
 ate, to a very great extent, the trouble and losses due to ice. During the last 
 winter season, the liver was examined for a distance of about 8 miles, and while 
 the flow was fairly large, the amount of ice formed was comparatively small, 
 onl> at two or three points in the section examined was there evidence of block- 
 mg and overflow; these were of very small extent. 
 
 The manipulation of the proposed Bow lake storage presents further diffi- 
 culties, but by special treatment these may be overcome. 
 
 To attempt to secure a continuous (Uscharge from that source throughout 
 the winter months, would mean practically the entire loss of the value of the 
 storage, the nature of the channel through which the water flows being very simi- 
 lar to that of the Cascade for nearly the entire length above Laggan. In order 
 that the maximum benefit may be secured from this basin, it is proposed to

 of the withdrawal of water by storage on the high summer flood, cannot be such 
 as to interfere with efficient irrigation; on the contrary, provision is made for 
 the future, because such a large supply cannot be maintained throughout the 
 entire irrigable season, and the month of April is much improved by storage 
 while September remains as before. 
 
 Under any circumstances, during the operations of water control and 
 supply from storage reservoirs, the requirements of irrigation should be kept 
 clearly in mind, and in the face of a threatened shortage, the reasonable demands 
 of irrigation must be given precedence.

 J. B. Challieh, Esq., 
 
 Superintendent of Water Power Branch, 
 Department of the Interior, 
 Ottawa. 
 
 Dear Sir,— In concluding my investigations and study of the Bow river 
 and its basin with respect to water supply, storage and regulation of discharge, 
 I have the following to bring to your attention. This report embraces recom- 
 mendations and suggestions for giving practical effect to the conclusions which 
 we have reached. 
 
 Scope. 
 
 The conclusions herein contained have reference to the water supply 
 question solely with respect to the regulation and control of the river so as to 
 equalize the discharge in the most advantageous manner for power purposes 
 keeping in mind the requirements of irrigation. 
 
 General. 
 
 If the country in the foot-hills east of the Rockies and within transmission 
 radius of the Bow river is to be encouraged as an industrial region, the utiliza- 
 tion of its natural resources is an economic necessity and the utmost develop- 
 ment of the water power of the Bow river is a logical outcome. In this region 
 there are already rapidly-growing industrial commimities and their steady 
 growth is dependent on probably no more important factor than an ample 
 supply of power. 
 
 The Bow river is peculiar in that, in its natural condition, its high summer- 
 flood discharge is upwards of seventy times its low-water winter discharge, a 
 condition which obviously renders its use, in its present state, unsuitable, 
 inefficient and commercially unfeasible for power purposes. 
 
 The investigations which have been carried on during the past two years, 
 the results of which have been embodied in the general report of Mr. Hendry 
 and in which I have collaborated, indicate that if the Bow river is to be an 
 efficient commercial source of power and at the same time to afford all ample 
 water supply for irrigation purposes it is absolutely necessary that the river be 
 regulated and controlled so as to ensure a fixed and useful supply of water con- 
 tinuously throughout the year. 
 
 Conditions to be Met. 
 
 If the improvement of Bow river is undertaken for the advantage of the 
 power and irrigation industries it is obvious that it should be done by, and 
 remain under the control of, tlie Government because of the many conflicting 
 interests of water demand which would be involved. In addition to the irri-

 B. — Cr,n8truction. — The construction work involved in this project in its 
 entirety, in accordance with the report, comprises storage and regulating dams 
 on: — 
 
 1. Lake Minnewanka. 
 
 2. Bow lake 
 
 3. Spray River canyon (Spray lakes). 
 
 In order to carry this whole project to its logical conclusion, it is evident that 
 the construction of these reservoirs should be undertaken as a Government work 
 in the same manner as the Government constructs other public improvements 
 for the benefit of the locality or the country at large. This undertaking has a 
 strong point in its favour, in that the Government can very rigfatly recover the 
 whole or a portion of the cost of the work in the form of annual rentals charged 
 to the various users for the additional water thus supplied. These rentals can 
 be adjusted amongst the various power companies or power sites in the leases 
 given by the department, and be recoverable with the annual power rentals. The 
 basis of water charge can be adjusted either according to quantity of water used 
 or to power produced, arranged on some equitable scale. 
 
 The first of the foregoing works has already been constructed and was 
 finished in time to catch the 1912 summer flood; the performance of this reservoir 
 and its regulation during the past winter has been made the subject of con- 
 siderable study and will form the basis of the further investigations which I hayt 
 suggested above. This reservoir with its accessory works was constructed at the 
 expense of the Calgary Power Company with an arrangement whereby the 
 Government may take it over at cost at any time in the future, and on this 
 account the work was done under the supervision of the Government's engineers 
 and accepted by them with a view to its ultimately becoming a part of the 
 proposed storage and regulation system. In this respect, therefore, the way 
 18 already prepared for carrying out the Governmental policy outlined above. 
 
 CO-OPIERATION. 
 
 As has already been stated, it is necessary to the success of the project that 
 the operation of the storage and regulation be solely under the control of the 
 Government. The authority could best be vested in an engineer located on the 
 ground, say at Banff, who would apportion the water and adjudicate between 
 the users and he, through his several assistants, would actually carry out this 
 process from day to day or week to week as the occasion might arise. These 
 operations would apply to water for irrigation purposes as well as for power. 
 
 In addition to these duties of regulation, this Engineer would also be 
 charged with continuing and collecting the various data and information already 
 outlined consequent upon operation. 
 
 The cost of up-keep and maintenance of the works, as well as the expense 
 of the actual operation of the regulation by the Government, can be apportioned 
 yearly amongst the various users in the same manner as already outlined for 
 repayment of the construction cost. 
 
 Recommendations. 
 
 In conclusion, and in accordance with the foregoing I have the following 
 commendations to offer as being designed to meet the general conditions; — 
 
 1. That the investigations on the Bow River basin be continued for 
 the purpose of maldng the data more complete and useful in the subsequent 
 operation of the project. 
 
 2. That the Government undertake the further construction of 
 storage reservoirs and regulating works and provide for the repayment of 
 their cost by means of annual rentals charged to users of water.

 Proposed Dam at Sprat River, British Columbia. 
 
 Sib, — In accordance with your request, I have reviewed the available data 
 that you have obtained with regard to the possibilities of constructing a storage 
 dam at the Spray River canyon in Alberta. The construction of a dam 
 with a proposed maximum height of 100 feet in a place so remote from rail 
 transportation involves the consideration of several points that are of extreme 
 importance when considering the subject from the economical standpoint. 
 The diflSculties of access to the site and high cost of materials that may require 
 to be transported to that site, makes it imperative to select a type of dam that 
 while absolutely safe shall be constructed at the lowest cost. From careful 
 consideration of the data available with regard to vhe proposed location, I 
 believe, subject to further investigation as to the foundation conditions, that 
 a dam can be safely constructed there either of concrete masonry, rock-fill, or 
 of earth work, the latter either of the ordinary type or constructed by the 
 hydraulic-fill method. 
 
 To determine the approximate cost of a concrete dam designed either as a 
 gravity dam or one of the arch type, much careful exploration work by means 
 of test pits and diamond drill borings is absolutely necessary; but after taking 
 into consideration the high cost of cement and materials, and the diflacuJty of 
 transporting the large amount of plant necessary for its construction a distance 
 of 30 miles from the Canadian Pacific Railway, it is obvious that an approximate 
 estimate, bajed upon reasonable assumptions with regard to foundation con- 
 ditions makes it necessary to dismiss a proposal for a concrete dam from practical 
 consideration. I have, though, made an approximate estimate of the cost 
 of a typical gravity dam for the purpose of comparison with other types. 
 From the general geological character of the canyon, the type of dam most 
 suitable for the location is either one of a rock-fill type or an earthen dam, 
 preferably of the hydraulic-fill type. 
 
 Rock-fill Dam.— A dam of the best rock-fill type, such, for example, as the 
 Morena dam in California, is quite feasible and entirely suitable for the site, 
 and satisfactory rock could be quarried at a convenient elevation so that the 
 material could be handled by gravity at an economical figure. This type, how- 
 ever, involves the use of large quantities of concrete for obtaining a water- 
 tight upstream face, and considerable plant to handle the rock ■ ' onomically, 
 and, in ac^ '.tion, its construction would be prolonged over se al seasons. 
 An approximate estimate shows, too, that its cost is prohibitive. 
 
 Earth Dam. — From a consideration of the materials available r.t the site 
 at a suitable elevation so as to be economically placed in the dam, I am of the 
 opinion that a dam of the hydraulic-fill type which has been proposed is the most 
 suitable and economical one to adopt.

 This type has already been adopted in building two large dams in British 
 Columbia, one a dam 1 ,000 feet long and 60 feet high at Bear creek, Vancouver 
 island, for the Vancouver Island Power Company, where the construction of 
 the dam had to be carried on in a very inaccessible region and under severe 
 winter conditions, and the other a dam at the outlet of Coquitlam lake, for the 
 Vancouver Power Company. The latter dam is 99 feet high and contains 
 nearly 600,000 cubic yards of material. Both of these dams have been built 
 of glacial drift, and in the case of Coquitlam a homogeneous dam of clay con- 
 crete of an excellent character was obtained. In my opinion the glacial clays 
 of British Columbia aiford the very finest material for constructing a satis- 
 factory dam if the materials are graded with skill, and are infinitely superior 
 to clays of a purer and richer character. From a consideration of the samples 
 that were examined by Mr. G. L. Albert, it appears that a satisfactory grading 
 of materials could be obtained for forming an impervious core. The chief 
 difficulty, in my opinion, however, is in the apparent scarcity of heavy boulders 
 for the outer slopes, a scarcity which may, however, be overcome by quarrying 
 quantities of rock near the site for incorporation with the sluiced material. 
 
 In constructing a dam of the height proposed, which is well below the limit 
 of the height of a number of other similar dams that have been successfully 
 completed, great care must be taken to ensure the provision of ample rock toes 
 of Cyclopean rubble, and at the same time to limit the amount of fine impervious 
 material in the centre of the dam only to what is necessary to ensure water 
 tightness. In the construction of the Necaxa dam No. 2 in Mexico, a dam 
 190 feet in height, the preponderance of rich clays and fine impervious material 
 was the cause of serious disaster, and in the reconstruction of that dam, as 
 actually built, the rock toes were so heavy and massive that the proportion of 
 impervious material was reduced considerably beyond that called for in the 
 original design; in fact, the revised design differs in very many important 
 essentials from that as originally published.' The lessons learned from the pprt- 
 ial failure of the Necaxa dam are very instructive, and must be borne in mind 
 in designing dams of the hydraulic-fill type. 
 
 The available materials for the hydraulic-fill at the Spray canyon appear 
 to me iyj be eminently satisfactory for obtaining a properly graded fill through- 
 out tht Jtiajor portion of the dam. The proportions of sand and gravel are such 
 that a proper drainage of the interior mass i an be obtained so that the stability 
 of the w'f ole can be secured. The material appears to be lacking in large 
 boulders of rock, but the proximity to the dam location of an excellent site 
 for quarrying limestone rock will enable large quantities to be secured if neces- 
 bary at an economicpl cost for the outer or more porous section of the dam 
 so as to increase its stability. From the general character of the rock, it wou'd 
 appear possible to break it up with black powder into comparatively smail 
 fragments and convey it by sluicing to the dt.m. 
 
 After ci» efuUy studying the available information, I have proposed in the 
 sketch attached hereivith the main outline of a suitable maximum cross-section 
 of the dam. Further information should be available before the exact founda- 
 tion conditions are settled, and I would recommend that a series of test pits 
 be sunk along the ctatr j fine of the proposed dam. 
 
 The base of the dam for a distance of 400 feet along the river bed should 
 be thoroughly cleaned to expose bedrock, and the whole of the site should be 
 thoroughly cleared of all roots, stumps, and loose material, and a core wall of 
 concrete, carried well into the bedrock across the river-bed and stepped up the 
 side slopes, is, in my judgment, necessary to obtain a perfectly water-tight seal

 The provision of a centre core wall of the full height of the dam would not only 
 involve a heavy expenditure, but would be unnecessary, and, in fact, dangerous, 
 because of its interference with the proper drainage of the glacial material in a 
 dam of the character proposed. 
 
 The only justification for core walls in hydraulic-fill dams is where there is 
 a danger from burrowing rodents, and even in such cases reliance upon properly 
 riprapped slopes would be more satisfactory, but I believe the danger of damage 
 from burrowing animals at the Spray canyon site is not present. 
 
 In the Bear Creek dam, Jordan river, a satisfactory cut-off wall was ob- 
 tamed where the rock lay 30 to 40 feet below the surface, by the use of interlocking 
 steel piles. In the Coquitlam dam a core wall about 4 feet high was constructed 
 on the east bank, founded on the rock ledge, but this wall was not carried across 
 the clay foundation. In the design which I have indicated, allowance has been 
 made for heavy cyclopean rock toes, upstream and downstream, and if it was 
 found economical to quarry rock, these toes could be increased considerably 
 beyond the dimensions shown, with advantage. 
 
 In constructing the dam, two seasons will be required for the sluicing. 
 In the construction of the Coquitlam dam 77,700 yards of material were sluiced 
 into place during one month in a run of 528 hours, with a monitor pressure of 
 80 pounds per square inch, representing with a twenty hours' daily run, an 
 average of 2,800 yards daily. The special conditions, however, existing at this 
 dam permitted that quantity to be safely sluiced into the work owing to the 
 massive proportions of the heavy cyclopean rock-fill toes and broad bases, but in 
 the case of the dam at the Spray canyon, to obtain proper drainage of the 
 materials, this speed should not be attempted, owing to the rapid increase of 
 height which would i>e obtained in so short a dam. If the total quantity of 
 material to be placed in the dam, amounting to approximately 500,000 cubic 
 yards, excluding the rock toes, two shifts daily of ten hours each, at an average 
 of 1,500 cubic yards, will mean eleven months' work distributed over two work- 
 ing seasons. It is advisable during the winter months to close down the work 
 entirely, otherwise the cost would be excessive. I have proposed that the up- 
 stream slope shoulJ be heavily riprapped, and near the crest the riprapping 
 should be grouted or laid in cement so as to prevent wave action (which will 
 probably be^ cof «>= "erahle), from damaging the dam at high-water line. In 
 
 mnel, I believe a spillway having a capacity of not less 
 second should be provided on the west bank, as this 
 • discharged under flood conditions with a full reservoir, 
 ..t the intake tower at the same time. This spillway 
 .own to the level of the rock, and if necessary a concrete 
 wall carried across so as to bring it to the required level, and a channel excavated, 
 ^r a retaining wall built, so as to prevent the water overflowing on to the down- 
 stream .'ftce of the dam. The exact location of the spillway and channel can be 
 determined when locating the borrow pits so as to reduce the excavation as 
 much as possible. 
 
 The design of the intake tower and the construction of the tunnel presents 
 no difficulties. Duplicate sets of valves of the Stoney pattern similar to those 
 in use at the Coquitlan-Buntzen tunnel can be easily adapted for control pur- 
 poses. 
 
 I have given careful consideration to the cost of building this dam, and 
 believe the hydraulic-fill type can be constructed at a considerably less cost than 
 any other type. One of the principal items involved, viz., that of sluicing the 
 hydraulic-fill, varies considerably in different dams. At Bear creek, .Jordan river, 
 where 160,000 cubic yards were placed in position by the hydraulic method, 
 the cost, including plant, etc., amounted to 49}4 cents per cubic yard; at the 
 Coquitlam dam the labour cost varied in different months between ten cents and 
 
 25e— 12i 
 
 addition to the 
 than 12,000 cu,

 and a possible

%m

 twenty-two cents a cubic yard; the average labour cost, including the con- 
 struction of flumes, their removal, etc., during the whole period of sluicing 
 460,000 cubic yards was 17 cents; the average cost, including plant, pumping, 
 power (electric energy charged \4 cent per k.w.h.) and supermtendence was 29 
 cents per cubic yard. 
 
 The convenient position of the borrow pits at the Spi^y Canyon site and the 
 class of material, together with an available water power for a temporary hydro- 
 electric installation, should make an estimate of 30 cents a cubic yard a sufficient 
 one. This figure, however, may be a little low if it is found nt-cessary to quarry 
 rock to incorporate in the hydraulic fill at the outer slopes of the dam. I estimate 
 that not less than 16 per cent of the quantities of material in the dam (exclusive 
 of the rock toes) will require to be of large boulders or rock, say about 75,000 
 cubic yards. 
 
 For the cyclopean rock toes, the loose rock obtained in stripping the found- 
 ations in the centre of the dam and the excavations from the tunnel may be 
 utilized to advantage. To the estimate in Mr. Hendry's report, I should prefer, 
 to be on the conservative side, to add the sum of $44,000 to item No. 5 for 
 heavy cyclopean rock toes, and with the available information which you have 
 already obtained, I believe the sum of $558,000 as. the cost of constructing the 
 dam to be a reasonably approximate one, although the estimates may require 
 revision upon fuller investigation and exploration work. 
 
 From estimates which I have prepared, the following is a comparative 
 estimate of the cost of different types of dams:— 
 
 Concrete Dam $1 ,350,000.00 $8.00 per acre-foot. 
 
 Rock Fill Dam (288,000 cu. yds.) . 810,000.00 4.75 " " " 
 
 Hydraulic Fill Dam 558,000.00 3.25 " " " 
 
 Even if the above estimate for an hydraulic-fill dam is slightly exceeded, its 
 cost will be very economical and reasonable, and will compare most favourably 
 with that obtained by the construction of other high dams, and the available 
 water storage will have been obtained at a much lower cost than has been ob- 
 tained by the building of other storage dams in British Columbia and on the 
 Pacific coast. 
 
 I recommend further explorations of the foundations, and believe it to be 
 important to obtain a report from a competent geologist dealing with the strati- 
 graphical features of the site and basin. 
 
 The proposal to build a dam at this site appears to be an excellent one, 
 and from the information already available would appear to present no special 
 engineering difficulties. 
 
 Yours faithfully,

 PROPOSED DAM AT SPRAY LAKES 
 
 (By Gi:o. L. Albert). 
 
 „ „ ^ „ Banff, Alta., July 19, 1913. 
 
 Mb. M. C. Hendry, B.A.Sc, 
 
 Chief Engineer, Bow River Survey. 
 
 Dear Sir,— According to the agreement made with you at Coquitlam dam, 
 I beg to hand you herewith report upon the investigation made by me, during 
 the past few days, into the feasibility of placing a hydraulic-fill dam in the 
 canyon on Spray river below Spray lakes; also the suitability of the adjacent 
 material to that form of construction. 
 
 Canyon and Formation. 
 
 The canyon is a deep, narrow gorge, formed in limestone, and evidently 
 foliowmg the course of an old fault. I found that the bedding planes of the 
 limestone on the west wall of canyon were lymg nearly horizontal, east and 
 west, and with a slight dip, or strike, south; the canyon wall on this west side 
 rismg to an elevation of about 160 feet above river-bed, and is very precipitous 
 but not so nearly vertical as on the east side. 
 
 On east wall the bedding planes have been turned up nearly vertical, 
 running north and south with, or parallelbg, the river, and rising to an elevation 
 of about 200 feet or more above the river-bed. 
 
 Dam Sites. 
 
 I first made a general examination of the canyon and selected three points 
 for study and comparison, which I will distinguish by numbering as follows:— 
 
 Site No. 1, or Lower, 
 
 Site No. 2, or Middle, 
 
 Site No. 3, or Upper. 
 SiU No. 1 is at the narrowest part of gorge, 1,000 or 1,200 feet downstream 
 from the beginning of the canyon, with the center line of the proposed dam 
 falling across the river through the center of the cliSF. At this point it approxi- 
 mated very nearly to the site pointed out by you as the one having been selected. 
 This site would require lef^s material, likely, than either site No. 2 or site No. 3; 
 but after a careful study md examination of the walls. I found that the west 
 wall is shattered and seamy for some depth into the side of wall from top to 
 bottom, necessitating expensive cleaning. The east wall is very clean on the face • 
 but back m the wall from about 25 to 40 feet, the strata are badly seamed and 
 parted, plainly showing the effects of the milling in the faulting; and the seams 
 being partlv refilled with hydrated fragments, and very porous, would make 
 a good seal doubtful without a great deal of special work. Both rock walls 
 rise to a suPicient height to admit of a dam of the proposed elevation, which is. 
 I under8tat.J, approximately 160 feet. 
 
 . Site No. 2 is 160 or 200 feet upstream from site No. 1, with all conditions as 
 at «t* No. 1 except that .i!! nf the shattered material on the west side, and all 
 of the seamed and hydrated materials on the east side have been torn oflf, and 
 worked and slid away; so that little or no work would be necemary to secure an 
 absolutely safe seal to a good bonding surface.

 points; the samples being panned or washed in water in such a manner as to 
 separate and grade the material, showing approximately the percentage of the 
 fine and coarse material combine. 
 
 Commencing at the lake on both sides, I made a very careful examination of 
 all material from river level to the top of the hills, and on below sides, by making 
 many test holes, and only taking samples where a marked difference in class 
 would show. As generally taken, the material was sufficiently uniform to be 
 judged, as a whole, as almost ideal material for the work proposed. As pre- 
 viously stated herein, the deposits being much deeper on the west side than on the 
 east side, and consequently being at a lower level on the west side, the percentages 
 of clay and fine sand are greater than on the east side; more particularly so near 
 bedrock, the coarser materials lying nearer the top. The great depth of the 
 deposit and very convenient location suggests the west side for the choice of 
 borrow pits. 
 
 The percentages given below of the various samples do not show accurately 
 the proportions as found in each small sample of about one-half cubic foot of the 
 material washed; but gives very closely the proportions of the aggregate at the 
 place of taking, considered as deposited in an hydraulic-fill. 
 
 I have delivered to you two samples of the best clay and sand deposit, which 
 I would suggest that you have tested. The sample of the pulverized material 
 is from an exposed bank of clay on west side, and about 300 feet upstream from 
 site No. 2. It is off the surface, and is principally clay and fine sand. The solid 
 sample is from an excavation made in an old slide near the upper end of canyon 
 on west side. I estimated that it contained about 15 per cent of moisture when 
 first taken out, and about 60 per cent of clay and fine sand, and about 25 per 
 cent of coarse sand and gravel. 
 
 This material alone would give more puddle material than would be neces- 
 sary; but estimating the whole deposit as taken in the construction, there is 
 sufficient of all grades to make it especially good. 
 
 The tests of all samples on west side, taken near bedrock, showed about 
 as these samples: —

 THE GEOLOGY OF THE BOW RIVER BASIN 
 
 (By Charles Camsell, B.Sc, Ph. D.) 
 
 INTRODUCTORY STATEMENT. 
 
 The information contained in t'.iis portion of the report is compiled wholly 
 hom reports of officers of the Geological Survey, and mainly from those of 
 Dawson, McConneil, Cairnes, Powling, and Allan. Much of it is copied verbatim 
 from the Guide Books prepared by J. A. Allan and D. B. Dowling for the Inter- 
 national Geological Congress in 1913. 
 
 The following reports deal more fully with the geology of certain portions 
 of the Bow River basin: —

 Dowling, D. B.— Winnipeg to Bankhead, Guide Book No. 8, part 1, page 77. 
 
 General Physical Features. 
 
 The basin of Bow river west of Calgary lies on the eastern slope of the 
 Rocky Mountain system, between latitude 50° 30' and latitude 51° 45'. In this 
 basin are three distinct types of topographic form, the western, including the 
 rugged alpine region of the eastern ranges of thi Rocky Mountain system, the 
 middle covering the more rolling foothills region, and the eastern the level 
 plains region about Calgary. 
 
 The Rocky mountains here, as elsewhere, are made up of a series of paralhl 
 ranges striking about N. 30° W., and coinciding more or less closely with the 
 general tiend of the main mountain system. Between the ranges are deep 
 longitudinal valleys whose positions have been determined by the presence of 
 belts of softer rocks. Crossing the ranges here and there at right angles are 
 a number of transverse gaps through which the larger streams break on their 
 way eastward to the plains. The pattern produced by this system of drainage 
 IS that of a series of oblong, rectangular blocks, the longer directions of which 
 are parallel to the trend of the mountain axis, while the shorter are at right angles 
 to it. 
 
 The origin of the longitudinal valleys is directly connected with the origin 
 of the mountains themselves. The transverse valleys, however, may represent 
 portions of very old drainage systems which existed previous to the elevation 
 of the mountains, or they are due to erosion of the streams along lines of weak- 
 ness or fracturing developed during the period of mountain building. 
 
 Bow river is in some places longitudinal and in others transverse. For 
 example, from Laggan down to Sawback it occupies a longitudi'"'' valley that 
 
178 
 
 DMfABTMMSJ O' TBM INTERIOR 
 
 6 QEORQE v., A. 1915 
 
 has been cut out by the stream along the crest of a fold in the strata. From 
 Sawback it turns eastward and as far as Bankhead occupies a transverse break 
 across the strike of the bedrock and across the trend of the ranges. It then 
 reaches a belt of soft rocks which deflects its course again southeastward down 
 a longitudinal valley until below Canmore it again turns at right angles and 
 breaks through the outer ranges into the foothills region. 
 
 The loftiest summits of these ranges are those about the main divide, 
 where several individual peaks are more than 11,000 feet above sea-level. A 
 number of mountains exceed 10,000 feet and whole ranges and groups of peaks 
 surpass 8,000 feet. 
 
 The tjrpe of mountain most commonly developed in the Bow River baein 
 is that with a steep escarpment on the east side and a longer ec^y slope on the 
 west side. This feature, like that of the longitudinal valleys, can be attributed 
 to elevation of the mountains by thrust from the west, the strata having been 
 folded and overturned, or broker and overthrust on each other. Erosion then 
 produces the steep ea&tern slope, while the easy western slope represents the 
 original dip of the strata. V/here the i^ummits are composed of horiiiontal beds 
 of massive limestones the easy breaking of the beds along joint planes at right 
 angles to the beddii^ produces mountains of which the upper parts are sheer 
 cliffs. A later stage in decay of these mountains results in chimney or spire-like 
 
 Seaks. Where the limes. . jne beds have been turned completely on edge as in the 
 awback range the massive character is replaced by straight narrow crests and 
 saw-like outlines. 
 
 The break between the mountains and the foothills is sharp and distinct 
 and marked by the abrupt escarpment-like front of the Rocky mountains. 
 
 The foothills region is characterized by a group of long ridges or hills arranged 
 in linear series, the positions of which have been determined by zones of harder 
 rocks. The trend of the ridges is the same as in the main ranges, and to a certain 
 extent the same general drainage pattern holds. 
 
 The summits of the ridges are generally rounded and flowing, except where 
 crested with ledges of sandstone. While the distul-ba;nce of the bedrock in tie 
 foothills is not less than that found in the mountains the more subdued topo- 
 graphic outlines of the former are due to their being composed of much younger 
 and softer rocks which are less resistant to the action of erosion and denudation. 
 
 Topographically the foot-hills region merges gradually into prairie region 
 on the east, the open rolling character of which is due primarily to the almost 
 undisturbed attitude of its underlying bed rock. 
 
 Stratigraphy. 
 
 The rocks of the Bow River basin above C'llgary contain representatives 
 of almost every age rom Pre-Cambrian to Recent, or from the oldest to the 
 youngest. They are all stratified rocks and the sequence is exposed in des- 
 cending order from east to west, the strata about the main divide being the 
 oldest. The missing formations are those of the upper part of the Tertiary, the 
 Silurian and the Ordoviciaii. The la. ' two mentioned, however, appear on the 
 western slope of the Rocky mountains.

 In sharp contrast with the underlying massive quartzites, there is a thin 
 series of siliceous and calcareous shales grouped as the Mount Whyte formation. 
 These shales are less resistant than the quartzite and form gradual sloi>e8. 
 Some of the layers contain numerous annelid borings and trails. 
 
 Middle Cambrian. 
 
 The Middle Cambrian ct)nsists of massive limestones and some shaly lime- 
 stone and calcareous shale. It forms the steep escarpment of the upper part 
 of the Castle mountain and occurs again on the sunmiit of the main divide in 
 the Bow range and the Waputik mountains. 
 
 The Cathedral formation consists of massive and thin-beddetl dolomitic 
 limestone, which on the weathered surface becomes buff and grey. The more 
 massive beds are arenaceous in their conijwsition. The Monarch mine, in 
 mount Stephen, and other small mineral prospects in the Kicking Horse valley, 
 are in this formation. 
 
 Some of the limestone has become metamorphosed into marble. One of the 
 best exposures of this rock is in Cathedral mountain, 4 miles east of Field. 
 
 The Stephen formation is only 640 feet thick, but it is important for the 
 number and variety of fossils which it contains. It consists of shaly limestone and 
 calcareous shale. These beds include the "Ogygopsis shale" in mount Stephen, 
 and the "Burgess shale" in mount Field, on the opposite side of the valley. 
 T >' former includes the widely known trilobite-bearing "fossil bed," while 
 the latter includes the new "fossil bed" discovered bv Dr. C. D. W'alcott in 
 1910. 
 
 The Eldon fonnation has a thickness of 2,728 feet in Castle mountain. 
 It consists essentially of massive-be<lded, arenaceous limestones, which form 
 steep castellated crags on the erosion surface, thus making the formation readily 
 recognizable wherever exposed. It is this formation which forms the steep 
 escarpment about the ujiper part of Castle mountain. 
 
 I'ppEB Cambrian. 
 
 The Bosworth formation of the Upper Cambrian is ex|)osed in the mountain 
 of the same name on the continental divide. It consists largely of thin-bedded 
 limestone with a few more thlck-bcihled layers, interbeddcd with siliceous and 
 arenaceous shale. One band of shale makes a good horlzon-nuirker because it 
 weathers greenish, yellowish, deep red and purplish. 
 
 The Paget formation is a band of greyish oolitic limestone, typically exposed 
 in Paget peak, on the west slope of mount Hosworth. These btnis can not be 
 readily distinguished from the underlying limestone. 
 
 The Slierbrooke fornuition consists of arenaceous limestone at the base, 
 overlain b ihin-bedded limestone, including some oolitic and shaly layers. 
 This f«>rmaiion includes the highest beds exi)osed in the How range in the vicinity 
 of Hector pass. 
 
 The remaining Cambrian formations, the Orilovician, and the Silurian, 
 are all exposed in the western portion of the Rocky mountains between the 
 Bow range and Columbia valley, and are not present in the basin of Bow river. 
 
 Devonian. 
 
 The Devonian occurs in a numi>er of bands which trend in a direction 
 parallel tu the axis of tlic niuuntaiii:^. One hand (To^c* the Bow Valley at the 
 (Jap, and another at the western end of Lac des Arcs. A third band overlies 
 the Cretaceous shales on the west sitle of Bow valley from Canmorc to Bank- 
 head. Other ban<ls occur in the N'ennilion lake and Sawback ranges.

 Permian. 
 
 The Upper Banff Shale lies conformably upon the Rocky Mountain quart- 
 zite and consists of a series of brown, calcareous and arenaceous, often sun- 
 cracked shales, interbedded with thin layers of sandstone. The shales weathar 
 out more easily than the underlying formations, forming valleys such as those 
 between the Cascade, Vermilion lake, and Sawback ranges. ^Iore than 1,400 
 feet of strata are represented in this section, but it is difficult to get an accurate 
 measurement on account of the foldings and cout. tions within the beds. 
 
 Jurassic. 
 
 Fernie Shale. — No sharp line can be drawn between the Upper Banff shale 
 and the Femie shale, except where fossils are found. The Fernie formation 
 consists of black and dark brown, siliceous, very thinly laminated shales which 
 break up into small fragments on the weathered surface. On the Cascade river 
 it contains some gray sandstone beds and an occasional limestone layer. West 
 of Banff it has a limited distribution, lying on the Upper Banff shale. Kast 
 of Banff and on the north side of the Cascade trough, it forms a band al)out 
 1,500 feet thick. The Fenie shale occurs near Exshaw « miles east of the ( iap. 
 
 Cretaceous. 
 
 The itaceous formations occur mainly in the foot-hills region from 
 Kananas. ^ to Cochrane. A narrow band occupies what is known as the Cascade 
 trough and extends from the head-waters of Cascatle river down the Cascade and 
 Bow valleys to Canmore and southward in that same direction across the upper 
 part of Kananaskis river. In the foothills the rocks are of the same character 
 and are so soft compared to the older rocks that they either floor the valleys 
 or produce a type of country that is more subdued in form than that of tlie 
 mountains. 
 
 Kootenay. — The lowest member of this formation rests upon the Jurassic 
 in the Rocky mountains, and forms the bottom of the Cascade trough. The 
 base of the formation consists of alternating beds of sandstone and shale, which 
 are succeeded by sandstones and sh.'iles and many coal seams. 
 
 The upper part of the formation consists of thin-bedded sandstones and 
 shales exposed in the eastern base of Cascade mountain. Near Banff the t(.i .' 
 thickness of this formation is over 4,000 feet. 
 
 Dakota. — In the mountains the coal-bearing Kootenay formation is over- 
 laid by a series of sandstones and conglomerates containing thin seams of coal. In 
 the foot-hills the sandstones are finer grained and are associated with some clays 
 and shales. The thickness in the foot-hills is about 950 feet. 
 
 Benton. — This is a, series of dark marine shales so soft and pliable as to be 
 easily folded and distorted. They weather easily so that the outcrop is usually 
 masked or marked by a depression. 
 
 Niobrara. — This formation is correlated with the Cardium sandstone, a 
 formation which is important as forming the series of falls and rapids on the Bow 
 river below Kananaskis. It consists of three sandstone beds, each capped 
 l)y a conglomerate and separated by shales. A detailed diagrammatic section 
 of this formation is given under the heading of "Bow Fort," in a later section 
 of this report. 
 
 Pierre. — Marine deposits containing some calcareous matter overlie the 
 Niobrara. They consist mamly of dark shales with some sandy beds in the 
 middle. They occur in the foot-hills region and are exposed in the valley of 
 Bow river below Bow Fort, where they have been folded into a series of anticlines 
 and synclines and faulted.

 region ,n which sediments were being laid down almost without Uiterruption 
 from Pre-( am brian imes to the close of the Cretaceous. The e^i >n f"rn "d

 the course of mountain building the strata were arched upward, compressed 
 and overturned on each other, and up-f()l<led portions were pushed miles to the 
 eastward over the level plains region. 
 
 The subsequent history of the region was in general one of erosion, that is to 
 say, the carving out of its valleys by the streams and the development of its 
 drainage system and a general wearing down of the mountain ranges. 
 
 GLACIATIOX. 
 
 During the Glacial period the Canadian Cordillera is believed to have 
 been covered by an ice cap much as that which covers Greenland or the Ant- 
 arctic continent to-day. This ice cap extended from the 48th to the 63rd 
 parallels of latitude, or a distance of about 1,200 miles. During the maximum 
 period of glaciation, the interior ice cap v.as fed by a double row of valley 
 glaciers, one flowing eastward from the Coast range and another westward from 
 the Rockies; the united stream then moved southward and northward over 
 the interior of British Columbia. The eastern slope of the Rockies was also 
 drained by eastward-moving valley glaciers which became confluent as piedmont 
 sheets on the plains of Alberta. 
 
 In the basin of Bow river all the valleys were occupied during the glacial 
 period by valley glaciers moving slowly down grade toward the east. These 
 valley glaciers, by the aid of rock fragments along thj bottom of the glaciers, 
 deepc: i and broadened the valleys and gave th^m the general outlines that 
 they have to-day. As the glaciers dwindled and retreated up the valleys they 
 left large quantities of loose materials in their train. At certain points glacial 
 lakes, dammed by ice tongues, were formed which received sediments in the 
 form of clays and sands. Towards the heads of the valleys basin-shaped cirques 
 were gouged out of the solid rock by means of mountain glaciers, the remnants 
 of larger valley glaciers. 
 
 SPRAY LAKES. 
 
 Spray lakes lie in a transverse valley, which cuts acroiss the general trend 
 of the mountain axis and which separates the (!oat range from Kananaskis 
 range. The valley was probably at one time the main course of Spray river, 
 but haying been filled with glacial material the stream became diverted and the 
 valley is only now occupied by a trilmtary of the main river. The Iake< are 
 stated by Dawson to be due to damming of the outlet by glacial materials or 
 debris washed down from tln' borderir™ mountains. 
 
 The part of the valley which it is proposed to utilize as a storage basin is 
 underlain by rocks of Pala>ozoic age Devonian and Carboniferous — consisting 
 mainly of limestones with soma quartzite and possibly shale. The strata have 
 l)een tilted, and on the northeast side of (ioat range dip at angles of about 45° 
 to the southwest. On the west side of the (Joat range tho dips average al.out 
 00° in the same directiim. The strike of the outcropping edges of the strata 
 coincides roughly with the trend oi" the mountain axis, so that on th ' msverse 
 portion of the valley at Sj)ray lakes the strike is directly acro.ss .: j valley, 
 while in the main valley of Spray river below S()ray lakes the strike is parallel 
 to the valley. At the point then where it is suggested the site of the dam should 
 be .e strike of the rocks is in general parallel to the course o^ t' o stream, 
 and the rocks themselves consist of limestone an.' (juartzite. 
 
 At Spray falls a ledge of pale grey limestone rn.sses the river, making a drop 
 of 40 f«H't. The remainder of the proposed stoiage basin is covered with uni'on- 
 solidated glacial anil stream deposits which ri'st with a variab'e thickness on 
 the upturned edges of the s'' Mk>.
