THOMPSON. il 429 REPORT UPON THE CONSTRUCTION OF TOPOGRAPHIC MAPS, AND THE SELECTION AND SURVEY OF RESERVOIR SITES IN THE HYDRO- GRAPHIC BASIN OF THE ARKANSAS RIVER IN COLORADO, By A. H. THOMPSON. TOPOGRAPHIC MAPS. That part of the hydrographic basin of the Arkansas river within the limits of the state of Colorado lies between the meridians 102 and 106 30' west longitude, and 37 and 39 30' latitude, and embraces an area of approximately 29,350 square miles. A topographic survey of this region was commenced by the parties of the U. S. Geological Survey under the immediate charge of Mr. Wil- lard D. Johnson, in September, 1889, and the work, both field and office, practically completed in June, 1891. This survey was undertaken primarily for the purpose of discovering and locating the reservoir sites within the drainage basin, the catch- ment area tributary to each reservoir site, the situation and area of irrigable lands, and to indicate in a closely approximate way the pos- sible location of canal lines to conduct the waters from the reservoirs to the lands. To give this data, maps were constructed on a scale of 1 : 125,000, or 2 miles to the inch, nearly ; the relief being shown by contour lines of equal altitudes having an interval of 100 feet in the mountainous coun- try, 50 feet in the less rugged country, and 25 feet in the plains region. In some cases all these contour intervals appear on the same sheet. The maps were constructed by atlas sheet areas embracing 30 minutes each way in latitude and longitude, conforming to the gen- eral plan for the Topographic Atlas of the United States, in the process of construction by the U. S. Geological Survey. The field work was done by plane table methods, the horizontal control being primarily based on the stations of the transcontinental triangulation of the U. S. Coast and Geodetic Survey, the primary stations in the triangulation of the U. S. Geological Survey of the territories, under Dr. F. V. Hayden, and the triangulation of the U. S. 431 432 TOPOGRAPHIC WORK IN THE ARKANSAS BASIN. Geological Survey either computed or graphic from these stations. The vertical control was based upon the altitudes furnished by the levels of the railroad lines within the basin as adjusted in Gannett's Diction- ary of Altitudes. From these base lines others were run to important control points, and to these bench marks were referred all the altitudes determined. The altitudes of most minor points were determined by angular lev- eling, though the aneroid barometer was extensively used during the first season's work. Most of the drainage lines and cliff edges of mesas were traversed, as were all public roads. All sketching of topographic forms was done on the plane table. During the first year the work was done on the small traverse plane tables and transferred to the final sheets, but afterwards all work was done on plane table sheets the full size of an atlas sheet, and all the drawing, except the lettering and final inking, done in the field ready for the engraver. At* least two and often five or six points in the pri- mary triangulation were located both in plane and in altitude on each atlas sheet, and used as- reference points for all the succeeding work. In the foothills and plains region these reference points were all per- manently marked. The field and office work was usually done on twice the scale in- tended for publication. Owing to great changes in the topographic features on the same atlas sheet, it was necessary to adopt different contour intervals on the same sheet in order to express the topography in a way to subserve the purposes of the maps. A small interval was necessary in the gently sloping regions in order to show the declivity of the irrigable lands and the approximate location of canal lines. In these regions 25 feet was adopted. It was not possible to carry this interval into the representation of the cliffs and steeper mountain slopes; sO in these regions the intervals of 50 or 100 feet was adopted, varying, of course, with the steepness of the country. In order clearly to represent these changes of contour interval on the same sheet, the engraver cut the lines of different widths or weights, the contours rep- resenting each thousand feet of elevation being the broadest, the lines representing each hundred feet change in elevation next less in width, and contours representing a change of interval of 25 feet the thinnest. Where the engraver executed the terms of his contract the result is excellent. The maps are all engraved on copper, three plates being required for each atlas sheet, the first showing the contours, the second the drainage lines, and the third the culture. These are printed in differ- ent colors, the contours being in brown, the drainage or water in blue, and the culture in black. In all 30 full atlas sheets and 10 fractional parts of atlas sheets were necessary to represent the drainage basin of the Arkansas river in Colorado.

From these maps a second map on the scale of 6 miles = 1 inch was compiled. This map includes only the drainage basin of that part of the Arkansas river lying in the state of Colorado. The topography is represented by contour lines having an interval of 100 feet in the plains region and 200 feet in the mountains. It also shows the principal streams, the larger towns, all surveyed reservoir sites, the boundaries of the tributary drainage basin, and the township lines of the Land Survey. TOPOGRAPHY. The hydrographic basin of the Arkansas river in Colorado presents three well defined areas of distinct types of topographic forms moun- tains, mesas, and plains. 13 GEOL., PT. in 28 434 TOPOGRAPHIC WORK IN THE ARKANSAS BASIN. The mountain area comprises the western third. It rises abruptly from the eastern plains and mesa regions, often in a bold escarpment thousands of feet in height, then rolls back a gradually rising region of mountain ranges, isolated peaks, deep canyons, and beautiful valleys to the western rim of the basin. Through this region the Arkansas river flows first in a southern, then in an eastern direction, dividing it into two almost equal parts. The upper and northern part of its course is in a mountain valley, too elevated for much cultivation of the soil, except near its southern ex- tremity. Its lower course is in close canyons, with walls often rising almost vertically 3,000 feet. The western rim of the basin is formed by three of the loftiest ranges in Colorado, the Sawatch, Sangre de Christo, and Culebra, each having summits over 14,000 feet in altitude. These ranges stretch in an irregular double curve southeastwardly from Tennessee pass on the north to the Boundary mountains, just be- low the dividing line between Colorado and New Mexico. The northern rim of the basin is less imposing from contrast with its western rival. Having the same point of origin (Tennessee pass) as the western rim, it swings in the arc of a great circle down the crest of the Park range round the Arkansas hills by Chalcedony butte to the junction of the Eampart range with the Arkansas divide, which forms the crest between the watersheds of the South Platte river and Monument creek. The eastern rim has a general north and south trend broken by a deep reentrant angle of mesa type of topography where it crosses the Arkansas river. Like the northern, it is less continuous as a mountain wall than the western rim. The Kauipart range, forming the rim north of the Arkansas river, rising abruptly from the plains and . having the great mass of Pike's peak at its southern extremity, is, however, as imposing as any of the western ranges. South of the Arkansas river the Wet mountains range forms the rim until they merge into the Spanish peaks and the eastern flank of the Culebras. The region included within these mountain walls is in the shape of an irregular triangle, its apex in Tennessee pass and its base the whole eastern rim. It comprises an area of approximately 28,600 square miles. The Arkansas river, flowing first in a southern and then in an east- ern direction, divides this region into two nearly equal parts. Its upper and southern course is in an open valley, but its lower and east- ern is in deep canyons, having, sometimes, walls 3,000 feet in height. It descends from the lofty summits of the western ranges to an alti- tude of 4,600 feet, where it enters the mesa country below Canyon city, a distance of 120 miles. West and south of the river their slopes are steeper; the drainage tributary streams are more numerous than on the east and north. The whole region is one of great precipitation and is the principal source of the water which the river bears to the plains. THOMPSON.] TOPOGRAPHY. 435 The mesa region extends from the mountains eastward into the plains. It also forms a prominent feature in the southern part of the basin. Definite limits can hardly be given to this region, as it grad- ually takes its distinctive features from the foothills of the mountain ranges and as gradually merges into the plains. Its mesas or tables range in altitude from 5,000 feet along the Arkansas river to 9,000 feet near the New Mexico line. The mesa region is more pronounced in type and greater in area in the southern part of the drainage basin than the northern. The plains region occupies by far the larger part of the drainage basin of the Arkansas river in Colorado, extending from the mesas to the eastern boundary of the state. It is divided into two nearly equal parts by the Arkansas river, which throughout has a nearly direct eastern course and forms the dividing line between two areas quite distinct in topographic details. The altitude of the immediate valley of the river is 4,650 feet at Pueblo, near the western limit of the region, and 3,350 feet at the eastern boun- dary of the state, a distance of approximately 150 miles by river. It is for the most part a narrow flood plain, lying but a few feet above the surface of the water, and bounded by well defined bluffs on either side. North of the river the country gradually rises from the bluff line to the divide between the Arkansas and the South Platte and Republican rivers. This slope has its greatest altitude at its western edge and decreases to the eastern boundary of the state, thus giving a general slope of the whole area towards the southeast, and this is also the usual direction of its drainage lines. It is a region scantily supplied with water, having no permanent streams, though the principal drainage lines carry water during the early spring months, and in the rainy months of summer are often raging torrents. These waterways have wide valleys with short lateral branches, thus leaving broad, gently undulating areas between con- siderable drainage lines. Quite frequently these undulating plateaus do not drain into adjacent valleys, but into depressions on their surfaces. Some of these depres- sions are of large extent. South of the Arkansas valley the topography is more broken, but still presents the general features of a great rolling plain, sloping towards the north and east and cut diagonally across by drainage lines having a general northeasterly course. The streams of these waterways are often in canyons, sometimes having walls 600 to 800 feet in height. This is more especially the case in the central portion of the area. RESERVOIR SITES. Instructions were given to the topographers engaged in field work to devote special attention to the discovery and location of all possible 436 TOPOGRAPBIC WOKK IN THE ARKANSAS BASIN. reservoir sites within the area surveyed by them, to the location of irrigable lands, and to the extent and classification of forest growth, distinguishing between the forests valuable for lumber and those valu- able for firewood, fencing, and other domestic purposes. One hundred and forty-seven possible reservoir sites were reported. Some of these were small, some were commanded by others more favor- ably situated to control to best advantage the waters of the given drainage basin, but all were given examination, and from the whole number reported forty-six were selected as being so located as to com- pletely store all the waters of the basin, and as being most favorable situations in regard to the irrigable lands. These sites were then surveyed to determine the best location for a dam, its height, the area that would be covered by water at the given height of dam, the approximate content of the reservoir and the sub- divisions of the Land Survey embraced within its limits. The field work was done with telescopic alidade, level, and stadia rods. In addition to the forty- six reservoir sites surveyed by the topog- raphers, nine were reported and surveyed by the engineering section of the Irrigation Survey, making fifty-five in all. The nine sites surveyed by the engineering section and numbered 1, 2, 3, 4, 5, 7, 25, 38, and 39 respectively, are not included in this report, having been described in the report of Mr. H. M. Wilson on engineer- ing work in Colorado. Of the forty-six reservoir sites surveyed, twenty-five are in the mountain region and twenty-one in the mesa and plains regions. Three of the sites, numbers 44, 45, and 46 are so situated that they have practically no catchment area. They could, however, be easily filled by high line canals from the Arkansas river. All the others have drainage basins of considerable extent, generally large enough to fill the reservoir. A short description of each reservoir site is submitted. A more detailed report of the survey of these reservoir sites was published in part 2 of the Twelfth Annual Report of the Director of the U. S. Geological Survey, an abstract from which is here given. RESERVOIR SITE No. 6. Is situated in Chaffee county, Colorado, on Sevenmile creek, near junction with Arkansas river.

BY A. H. THOMPSON. INTRODUCTION. Thirteen reservoir sites, numbered from 1 to 13, inclusive, were sur- veyed by the Division of Topography during the fiscal year ending June 30, 1892. Number 1 of these sites, that of Bear lake, is situated partly in Utah and partly in Idaho. The others are entirely in Utah. These reservoir sites were recommended for reservation from sale or settlement in July and August, 1889, in conformity to act of Congress making appropriations for sundry civil expenses of the Government, approved October 2, 1888, and the act of August 30, 1890, making appropriations for the same purpose, but it was not practicable to commence their definite survey before May, 1891, at which time a party was organized for this purpose and placed under charge of Mr. Morris Bien, Topographer of the U. S. Geological Survey, assisted by Mr. W. B. Corse, Assistant Topographer. Work was prosecuted until the completion of the field surveys in July, 1891. The final plats of these surveys and schedules of lands segregated, showing in what range, township, section, and subdivision of section of the TJ. S. Land Survey these sites are situated, were submitted to the Secretary of the Interior, and their final reservation from entry, sale, or settlement, according to law, asked for under date of April 12, 1892. In the survey of these reservoir sites the topographers were instructed to consider the probable supply of water as indicated by the altitude and area of the drainage basin ; the declivity of its slopes, and whether forest-covered, grass clad, or bare; the rapidity with which water would be delivered into the reservoir; the best location for the dam, taking into account its length, height, availability of proper materials for its construction, and the opportunity for a sufficient spillway ; the nearness of cultivable lands and the grade of canal line required to convey the waters to these lands; and, if any choice could be made, they were directed to locate the dams where these requirements were best fulfilled. 451 452 LOCATION AND SURVEY OF RESERVOIR SITES. In the reports upon the surveys of these reservoir sites the name and situation of each are given, the area and general altitude of its drain- age basin; the general character of the topography; the township, range, sections, and subdivisions of each site; the height and location of dam ; the bench mark of the survey ; the area in acres and approxi- mate content of the reservoir in acre-feet, where material for construc- tion of dam can be found, and the situation of available irrigable lands. The plats show the situation of the reservoir site in reference to the subdivisions of the U. S. Laud Survey, and the approximate location on the same of the line of the water surface at the given height of dam, and they are accompanied by schedules in terms of the General Land Survey to the nearest 40-acre division the areas in- cluded, and also by another schedule showing as nearly as can be as- certained, from the records of the General Land Office, whether the lands affected belong to the public domain or to individuals. The reports, plats, and schedules are designated by corresponding numbers for each reservoir site, a distinct series being used for each state. In addition the figure number of this volume is given for each plat in the report for its site. UTAH-IDAHO. EESERVOIB SITE No. 1. (PL CLXXXIII.) Description. Reservoir site No. 1 is Bear lake, lying half in Rich county, Utah, and half in Bear lake county, Idaho. Its immediate drainage area is about 250 square miles, but the reservoir is to be supplied by a canal about 10 miles long from Bear river. The area drained by Bear river is 2,400 square miles, lying mostly in Wyoming. The drainage basin is generally well wooded ou the mountain slopes. The alti- tude of the lake is about 6,000 feet and the mountains run up to 10,000 feet. There are comparatively few stretches of rocky mountain slope. The reservoir site lies in the following townships and sections in Idaho, Boise merid- ian : T. 15 S., R. 43 E., Sees. 13, 24, 25, 36. T. 16 S., R. 43 E., Sees. 2, 11, 14, 22, 23, 27. Projected: T.15 S.,R.44E., Sees. 14, 15, 16, 17, 18, 23, 24, 25, 36 ; T.16 S..R.44 E., Sees. 1, 12, 13, 24, 25 ; and the following in Utah, Salt lake meridian : T. 13 N., R. 5 E., Sees. 3, 10, 15, 22, 23, 24, 25 ; T. 13 N., R. 6 E., Sees. 5, 8, 17, 19, 20, 30; T. 14 N., R. 5 E., Sees. 5, 8, 9, 16, 17, 21, 28, 33, 34 ; T. 14 N., R. 6 E., Sees. 4, 9, 16, 21, 28, 29, 32 ; T. 15 N., R. 5 E., Sec. 32 ; T. 15 N., R. 6 E., Sees. 33 and 34. The dam lies near the northeast corner of the S. E. J of the N. E. J, Sec. 17, T. 15 S., R. 44 E., Boise meridian, Idaho. A bench mark was deeply cut on the floor of the road bridge crossing the outlet. The top of the dam is 3 feet above water level and 55 feet long. For 1,800 feet in one place a levee of about 2 feet will be required. The elevation of the lake is 5,946 feet abeve sea level. The water line was run by a plane table traverse with stadia rod and intersections ; the area inclosed by it is 108 square miles 53J square miles in Idaho and 54J square miles in Utah and the approximate content is 208,000 acre-feet. It would necessarily be an overflow dam. There is an abundance of rock and timber within 3 miles of the dam and all along the lake shore, except at the northern and southern ends. There are farms along about half the lake shore. The water could be used in the valley of Bear river in Idaho and northern Utah. THIRTEENTH ANNUAL REPORT PL.

This narrow neck has been cut through and the old river bend, about 2 miles long, is now used for a canal. When the reservoir is constructed a dam 475 feet long and 16 feet high will be needed to cut off the old river bend. The first dam is in the cut previously spoken of and piling has been put in for construc- tion. A bench mark was cut on a post standing near the east end of the dam where construction had commenced.

A spillway could be cut in solid rock at east end of dam and would be 80 feet long. Rock and timber abound around the lake. There are no houses on the reservoir site, but several cultivated farms would be flooded. The water would be used on land at the town of Panquitch, 15 miles distant. The lake has already been raised by an eight-foot overflow daui, and the additional ten-foot dam would doubtless hold all the water the drainage area could supply. Any excess could be retained in Reservoir site No. 13, lying in the same drainage basin. Salt Lake Meridian. AT PANQUITCH LAKE.

RESE1WOIR SITE IN UTAH. 477 BESERVOIR SITE No. 13. (Fig. 10.) Description. Reservoir site No. 13 is at the Blue spring, 2 miles S. W. of Panquitch lake, in Iron county, T. 36 S., R. 7 W., Sees. 7, 8, 17, 18. Its drainage area is 25 square miles, well wooded with few rocky slopes. The dam lies in the middle of Sec. 7, at the upper end of the gorge of the outlet of the valley ; it is 48 feet high and 250 feet long. A bench mark was cut in solid rock at the west end. The water level was run with plane tahle, stadia rod and intersections; it in- closes an area of 440 acres and will contain 13,000 acre-feet of water. Its altitude is 8,200 feet. An overflow dam would be required. Reservoir site. Area segregated. FIG. 160. Reservoir site No. 13, at Blue spring, Iron county, Utah. Timber and rock are abundant on the site. There are 2 houses on the site. This reservoir would be supplementary to No. 12 for the supply of water to lands at Panquitch, 17 miles distant. Its principal supply is a large spring called Blue spring. The flow of this spring might be required in filling Reservoir No. 12, though in some years and possibly every year both No. 12 and No. 13 could be filled. Salt Lake Meridian. AT BLUE SPRING.
