L. Haehl, Consulting Engi- neer of San Francisco, for the use of valuable stream flow data collected by him on Coyote River in the years 1903 to 1907 and 1912 to 1914, and to F. H. Tibbetts, Consulting Engineer of San Francisco, for valuable percolation and well data collected by him in the years 1920-21 in connection with an investigation and report made by him and Stephen E. Kieffer for the Santa Clara Valley Water Conservation Committee. Statistics from the 1930 census as to irrigated acreage within the district were furnished by the Director of the U. S. Census, and Mr. Leroy Anderson, President of the Santa Clara Valley Water Conserva- tion District, canvassed the various growers and marketing associations for information as to acreage in the different irrigated crops. Mr. Anderson's advice and cooperation on many occasions are deserving of special mention. The San Jose Water Com])any and the Campbell Water Company furnished records of fluctuation of ground water level in some of their wells which makes it possible to connect the earlier records of the U. S. Geological Survey and Tibbetts and Kieffer with the records obtained by the Division during the course of this investigation. Ten private observers whose names are noted in Table 1 turned over to the Division their previous records of precipitation at stations maintained by them and reported current precipitation regularly dur- ing the course of the investigation. Tliese data were used in con- junction Avith the long term records of the U. S. Weather I'ui'oau at San Jose, Los Gatos, Lick Observatory and Gilroy. The following earlier rei)orts containing valuable data bearing upon the subject in hand are listed in their chronological order: U. S. Dept. Agriculture; O. E. S.

Percolation on ("oyote River is suscep- tible of determination within reasonably close limits because of the abundance of data which have been accumulated as to flow at various •jfaging stations and is estimated to approximate 23,000 acre-feet per year during a period of normal precipitation but data are lacking with which to make a similar estimate of the total percolation on other valley streams. How'ever, proven rates of percolation on these remain- ing streams are somewhat more than equal to those on the Coj'ote, which was measured at mucli higher stages, and it is believed the natural percolation from these other streams, due to the larger total quantities carried and the wider distribution and greater exposure to percolation, is several times as great as on the Coyote. 11. Whatever percolation is assumed for these remaining streams it appears clear that there are other sources of replenishment of ground water in Santa Clara Valley than from the streams traversing the valley floor. Thus the estimated draft during the two-year period December, 1930, to December, 1932, is 279,000 acre-feet, the estimated net loss in ground water storage is 51,000 acre-feet, and the estimated contribution of Coyote River to ground water is 21,500 acre-feet, which would indicate that if there were no other sources of replenishment than the Coyote the remaining streams must have contributed almost 10 times as much as the Coyote to ground water, and this is impossible. 12. The trend of the hydrograph showing a long term record of general ground water levels in the valley, which is presented on the opposite page, indicates that draft has not exceeded replenishment in years of normal precipitation. In the years 1915-16, 1920 to 1923, 1925 to 1927, and 1931-32 when precipitation was normal or slightly above there has been a recovery of ground water levels. During the year December, 1931, to December, 1932, there was a recovery in ground water storage estimated at 44,000 acre-feet, altliough precipi- tation was only slightly above normal and stream flow was slightly below normal. An examination of the plate in the pocket of this report entitled "Lines of Equal Fluctuation of Ground Water — December, 1931, to December, 1932," together with the records of individual wells from which this plate was prepared, Avill indicate, however, that there are small areas, particularly in the westerly portion of the valley, where there was no recovery during the year 1932 and that in these areas the recession of ground water in recent years has exceeded the average as shown by the compo.site curve of the plate opposite this page. In years of subnormal precipitation w4th resultant subnormal replenisiiment it will be observed that pumping draft is greatly increased, as in 1924, 1929, 1931, etc., thereby aggravating the recession. 14 DIVISION OP WATER RESOURCES 13. Ground water levels can also be raised and reserve storage increased by stimulating additional percolation, either by spreading stream flow at favorable points within and without the natural stream channels or b}^ extending the season of flow in the natural streams through the operation of surface reservoirs which would hold back flood crests normally escaping to the ocean, until a reduction of flow in the streams of the valley gives an opportunity for the absorption of reser- voir releases. The estimated amounts which can be conserved by surface storage and by increased facilities of varying capacities for spreading within and Avithout the respective stream channels arc shown in tables 12 to 15. 14. Conservation of the surface waste from streams debouching into and traversing Santa Clara Valley affords the best means of restoring ground water level and it is doubted that the importation of water from any foreign source would be necessary or economically desirable. SANTA CLARA INVESTIGATION 15 CITAPTP^R IT PRECIPITATION, STREAM FLOW, WASTE AND IRRIGATED ACREAGE Precipitation. Precipitation in Santa Clara Valley, as elsewhere in California, lias been subnormal in recent years as will be seen by reference to the plate on page 12, or to Table 2. It will be observed that the periods 1S89 to 1931, 1903 to 1920, and 1909 to 1919 were normal as to their cumulative totals of precipitation and that during the 15-year period 1916 to 1931 the average deficiency was over 16 per cent. The cumula- tive deficiency was equal to almost 2^ years of normal rainfall during the 15 years. Reference to Table 2 of this report will indicate that precipitation in Santa Clara Valley during the first year of this investigation aver- aged approximately 82 per cent of normal, during the second year approximately 50 per cent of normal, and during the third year approximately 105 per cent of normal, there being of course consider- able variation among the several rainfall stations. Long term records of daily precipitation are available through the U. S. Weather Bureau for stations at San Jose, Lick Observatory, Los Gatos and Gilroy. The annual records of these stations are shown in Table 2 together with the record of a private observer (Donald J. Ward) near Morgan Hill, the data afforded by the private station being included to 'piece out' the record of the Gilroy Station of the U. S. Weather Bureau which was abandoned in 1915. Precipitation records of nine private stations in addition to those of Donald J. Ward, were turned over to the Division by cooperative observers Avhose names are noted below in Table 1. A monthly sum- mary of these data may be found in Appendix B.

The daily records of precipitation at these private stations may be consulted in the office of the Division of Water Resources but are not reproduced in this report. Available Stream Flow Records. In addition to the records of occasional measurements made by Tibbetts and Kiefl'er and this office for the purpose of determining per- colation losses, which occasional measurements are described elsewhere in this report, there are records available of stream tlow into Santa Clara Valley covering considerable periods of time. By the courtesy of H. L. Ilaelil, consulting engineer of San Fran- cisco, heretofore unpublished records of measured flow of Coyote River at Coyote, Ford Road, and Julian Street for the years 1903 to 1907 and at Madronc for the years 1!)12 to 191-1 are made available in Appen- dix C. Records of the flow of Coyote River as measured by Mr. Ilaehl at Coj^ote and at Madroiic (lining llie period 1902 to 1912 have heretofore been pubiishd by llie li. S. Ceological Survey in Water Supply Paper 519, and a complete reeoi-d of the measured flow of Coyote River at ^Madrone and Edenvale is available through the U. S. Geological Survey for the years 1917 to date, and at Coyote for the years 1917 to 1923. immediately following the inception of this investigation con- tinuous recording gaging stations were established by the U. S. Geo- logical Survey, cooperating with this office, at the following points: Alamitos Creek near Edenvale. (luaclaliipe River near CJuadalupe. tliiadalupe liiver at San .lose. Iju.s Uatos Creek at l^os Cato.s. Stevens Ci'eek near CupertiiU). Records of the How at these stations may he obtained through the office of the U. S. Geological Survey.

(c) Berryessa Creek at Milpitas. Of this list of stations those preceded by the designation "a" were established as far upstream as i)raeticable for a determination of the surface inflow to the valley; those designated "b" were intended to measure the flow below all diversions where the measurement would be determinative of thp surface outflow from the valley into San Francisco Bay but it Avas later found necessary in some cases to establish stations further downstream because of local contributions due to precipitation on the valley floor, and these later stations are designated "c." The location of all stations is shown upon the general map which will be found in the pocket attached to the back cover of this report and a record of the measurements, expanded in so far as practicable by com- parison with nearby stations may be found in tables 6 and 7, the records for the "a" stations being expanded on a percentage basis by comparison with the monthly total flow at the Cupertino, Los Gatos, Guadalupe, Edenvale (on Alamitos Creek) and Madrone Stations and Ihe records of the ''b" and "c" stations being expcinded by a similar comparison with the monthly total flow at the San Jose, Edenvale (on C'oyote River) and Alviso Stations. During the season of 1931-32 there were probably more diversions made from the streams entering the valley than in any other recent year. These diversions varied in character from the large permanent ditches to semiportable pum])ing outfits and hastily constructed dams of planks, brush and debris. With the exception of the upper station on Penitencia Creek some diversions occurred above all stations. The lower stations are below all diversions with the exception of Silver-Dry Creek where a small amount of diversion occurred in the last few hun- dred yards above its junction with Coyote River. 22 DIVISION OF WATEK RESOURCES S vn .2'^ (iimdaiupe River at San Jose esoooooooo r- o CI o oooooooooooo o Coyote River near Edenvaie CCtnOOOOOOO Trcow ^- oo 00 o oooooooooooo o OS o H Z o O z o (/) CL. o u -^■MOOt^OOO-^O C*3 C^ 00 Oi 35 •* ^ lO ^ — C4 — OCJ3lO»COO«roOOOO — — -^r •»«• -^ »rt in c^ 00 « — — o S 1^ § -o 3 -* J<) a o «o a o -< 5!

This is caused by brush growth, the dumping of refuse and the filling in and l>lowing over of certain channels, and though common to all was most marked on the three streams of the Camjibell Creek system from Home- stead Road to Agnew, on the Silver-Dry Creek system from Tully Road to Stony Road and on Berryessa Creek from Morrill Road to ]\Iili)itas and was least in evidence on Penitencia Creek. These three regions 'exclusive of the Penitencia Cone) were inundated by streams over- flowing their banks during each of the heavier storms. The Agnew- Alviso territory was submerged by the overflow of Guadalupe River below BrokaAv Road, combined with that from Campbell Creek. Some iliree or four square miles adjacent to Cupertino on the southeast was also inundated due to local run-off from the hillsides rather than the overflow from streams. The inundated region between Tully Road and Stony Road received heavy contributions from the hills to the east, tliongli the water from Silver-Dry Creek was sufficient to flood the district. The run-off recorded at the following gaging stations does not re])resent the discharge of the streams during high stages due to over- flow of banks above the stations. Campbell Creek near Alviso. Silver-Dry Creek at East Santa Clara Street Berryessa Creek at Milpitas. Berryessa Creek at Oakland Highway. Estimates of Surface Flow Entering Santa Clara Valley. Available records of stream flow entering Santa Clara Valley, as noted above, with records of the discharge of Alameda Creek at Sunol Dam obtained from the U. S. Geological Survey, have been used to estimate the surface inflow entering the valley. A summary^ of these estimates will be found in Table 5. Two methods were tested as a check one against the other in esti- mating the mean annual run-off of Coyote River at Madrone during the jieriods without available records. In the first method available records were expanded by comparison of the indices of sea.sonal wetness taken from Table 2. In the second method available records were expanded by comparison with records of discharge of Alameda Creek at Sunol. The latter method gave results more nearly consistent with the meas- ured records and was therefore adopted. Three methods were tested in expanding the run-off records of Stevens, Los Gatos, Guadalupe and Alamitos Creeks; first by compari- son of indices of seasonal wetness at a group of precipitation stations on the west side of Santa Clara Valley ; second by comparison with the 26 DIVISION OF WATER RESOURCES flow of Alameda Creek at Siinol Dam ; third by comparison with the flow of Coyote River at Madrone. The second and third methods gave very similar results and therefore the iim-off of Stevens, Los Gatos, Guadalupe and Alamitos Creeks was estimated by comparison with the flow of Coyote River at ^Madrone durintr the period 1902 to 1932. The records of measured flow in those minor streams of the valley described under "Available Stream Flow Records" were expanded for the year 1931-1932 by comparison with the complete records on Coyote and Guadalupe Rivers and Alamitos, Los Gatos and Stevens Creeks. The relation of the rate of run-olT during the year 1931-1932 to the average elevation of the watershed was then analyzed and it Avas found that run-off was affected not alone directly by the average elevation of the watershed but apparently by some uncertain factor indicated by position in the valley — the run-off' being lightest on the east side includ- ing the Coyote River, next lightest on the extreme northwest including Stevens Creek, next heaviest on the southwest including the Calabazas and Cami)bell Creeks, and heaviest on the south including Los Gatos, Guadalupe, and Alamitos Creeks. Verification of the estimates of light run-off' on the extreme northwest was found in the records of measured run-oft' of San Franciscpiito Creek, and it is probable the heavy run-off on the south is due to the situation of these watersheds adjacent to passes through the Coast Range. The run-oft' of the remaining minor drainage areas feeding into the valley was estimated for the year 1931-1932 by comparison with run-off of the larger streams of the same group, for which some records were available, taking into account average elevation of watershed as well as position as to one or the other of the four grou|)s referred to above. All minor streams of the valley were then thiown into two groups, those ea.st of Coyote River, and those west of Coyote River, and the annual run-off of each of these two groups was estimated as a whole. The 42-year period 1889 to 1931 and the 23-year period 1903 to 1926 were each normal as to rainfall, it will be observed by reference to the plate on i>age 12 and it was found thai tlic estimated mean run-off of Coyote River for the 42-year period differed only very slightly from the mean of the 23-year period 1903 to 1926 for which the discharge was measured in all years except two. The mean anniuil run-off of the minor streams entering tlie valley was acordingly estimated by com- ])arison with the Coyote River diiiinu these 23 years. Surface Waste From Santa Clara Valley Streams. \)y ('\']>ansion of the rccoi-ds of nieasnrcd flow in Coyote River at Ednivalc it is |>i';icticable to foi-iii sonic fairly approxinmte estimate of the atuni.il waste which Coyote River discharges into San Francisco Bay, and by comparison of the recoi'ds of discharge at Edenvale in the SANTA CLARA INVESTIGATION 27 .season lI);U-;{2 with those of the diseliar^^e of other valley streams into San Francisco Bay. whicli discharge was for the most part measured diiriiiji: that season, it is possible to make an approximate estimate of the lonjr term average of waste from all streams. The measured waste of (luadalupe River at San Jose during the ])eriod January 1, 1930 to Ajiril 1. 1 !)."{;? a.ssists to a conclusion in the matter becausi; it will be observed by reference to Table 7 the combined waste of these two streams approximated 88 i)er cent of the total in 1931-32. While there is some percolation and some surface and other accre- tion on Coyote River below Edenvale it would appear that these are relatively unimportant and therefore the recorded flow at Edenvale gaging station may be taken as fairly rei)resentative of the surface waste of this stream. The record has been expanded to cover the period 1!)()2 to 1932 by comparison with the ]\Iadrone record, with due allow- ance for inflow and accretions, as shown in Table 10. It would appear that Coyote River during the ])ast 30 years has wasted an average of 4S,000 acre-feet annually into San PVancisco Bay and that the average wa.ste over a period of normal precipitation (1903 to 1926) approxi- mates 00,000 acre-feet i)er year, or 3 per cent less than the measured waste in 1931-32. The discharge of Guadalui)e River at San Jose may likeM'ise be taken as fairly representative of the waste of that stream, including Alamitos and Los Gatos Creeks, into San Francisco Bay. During the l)eriod January 1, 1930, to March 31, 1933, which includes substantially four years of run-otf, the flow at San Jose on the Guadalupe River approximated 67 per cent of that at Edenvale on the Coyote River. Assuming that this percentage represents fairly well the long term rela- tion of the waste of the two streams the average waste of Guadalupe River, during a period of normal rainfall, would approximate 37,000 acre-feet per year, or 15 j)er cent more than the measured waste in 1931-32. In the ab.sence of any other basis for an estimate it may be assumed that the normal relation of total waste from other surface streams of the valley is to that of the combined waste from Coyote River and Guada- lui)e River as in the season 1931-32. The average waste from these minor .streams over a period of normal precipitation under such an assumi)tion would approximate 12,000 acre-feet, and the combined total wa.ste from all streams entei'ing the valley would, over a period of normal rainfall, ajiproximate 104,000 acre-feet annually, but a portion of this of course accrues too low down to be conserved by any known l)racticable means. 28 DIVISION OF WATER RESOURCES CO < 1-1 b O Z o <: CO > a; < u < H Z (O o H >- OS H D H H M u I u K O < H 8 sa o COO o o cs r^o r- T^ O O O O — -1 o o 1 o ^4-^aft eo w3 -^ ^oc^iooooot^oocco 1 o Mr^»c ^ M ic *!»« ro -^ csi CO cx) r^ 00 ^ cs ro O o eS ^^z£ ^ CO -^ csdoor^oi od^ ■^ ^ cvi ««> U3 ^ u ao 00 ^ COO o o o o o o =: = = o r- O = oo t-^ B.

Reference to the contour iuhj) of ground water levels as of Decem- ber 1982 which is to be found in the pocket attached to the back cover of this report, and to similar maps for recent earlier years Mhich may be consulted in tlie office of tiu' Division, will indicate that the general level of ground water in San Clara Valley for some miles back from the shore of San Francisco Bay is at or below sea level. At the close of the irrigation season it has dropped during each of the past three years to more than 20 feet below sea level between Campbell and ^Mountain VieAv. Under such circumstances it is not expected that there presently is any appreciable wa.ste underground from Santa Clara Valley basin. In fact there is a possible danger that ultimately the flow may be reversed and an incursion of salt water occur unless the recession in ground water level is arrested. Irrigated Acreage. In 1930 ]Mr. Leroy Anderson, president of the Santa Clara Valley Water Conservation District, made a canvass of the various cooperative marketing associations of Santa Clara Valley and from their reports estimated that api)roximately 95,000 acres were then irrigated in that District. The Tibbett.s-Kieffer report referred to above indicates 86,042 acres irrigated in 1920 within the tentative boundaries of the proposed Santa Clara County Irrigation District, with a further area of 41,170 acres susceptible of irrigation but not yet irrigated. A comparison of their data with the 'irrigation map' of 1920 prepared by the U. S. Depart- ment of Agriculture in cooperation with the University of California, the California State Department of Irrigation, and the California State Water Commission indicates that there were some 5000 acres irrigated witliin the boundaries of the proposed District of 1920 which lie outside the boundai-ies of the present District. Figures of the U. S. Bui'eau of the Census indicate that tlie irri- gated area in Santa Clara County increased froni 70,:U2 acres in 1919 to i)(),l:5() acres in 1!)29 oi- roughly .'^7 ])er cent. It is believed that this area ha.s remained substantially constant since 1929. Based upon these meager data it is a.ssumed that roughly speaking 100.000 acres within Santa Clara Valley Water Conservation District and adjacent thereto now depend in whole or in part for their irrigation supply ui)07i the underlying ground water storage basin. SANTA CLARA INVESTIGATION 31 CHAPTER III GROUND WATER The Draft Upon Ground Water. Diversions for irriiratio]i and domostic use from surface streams within ilic vallc> llooi' are relatively unimportant because of the short duration of flow in these streams, irrijyation and domestic supplies in Santa Clara Valley being- drawn for tlie most i)art from ground water. A record of the draft of San Jose Water Company, which supplies most of the urban and some of the rural draft for domestic purposes, will be found in Table 8. There is no measurement of the draft for irrigation use and for the purpose of estimate one must rely either upon an assumed duty for irrigated crops or upon an assumed relation of draft for this use to the agricultural power load. H. L. Haehl in his review of F. II. Tibbetts "Report on Water Salvage Project" to the Board of Directors of Santa Clara Vallev Water Conservation District in October 1981 presents figures for power consumi)ti()n in San Jose District obtained from Pacific Gas and Elec- tric Company and these have been supplemented for the ensuing years tiirough the kindness of P. M. Downing, vice president and general manag:er of that company, who advises that the agricultural power load in this area in 19:U was 49,024.000 kilowatt hours and in 1932, 35,832,- 000 kilowatt hours. Assuming that tliis load is uniformly distributed throughout that portion of the valley in which the wells under observa- tion by the Division are located ; that the static pumping lift has varied each year from that of 1932 a.s the fluctuation in general ground water elevation has varied ; that an increment of 35 feet must be added to this pumping lift to cover 'draw-down,' friction losses, and height of delivery above ground surface ; and that the over-all efficiency of pump- ing plants is 50 |)er cent; an estimate has been made of the annual pumping draft upon the ground water basin for irrigation uses. While these assumptions are a matter of judgment and opinions with respect thereto will differ, nevertheless it is believed they make j)Ossible an estimate which, if not strictly accurate for any given year, is nevertheless fairly accurate for comparative purposes one year with another. The estimate thus made is shown in Table 8. It appears that the total pumping draft upon the ground water supply increased from 25,000 acre-feet per annum in 1915 to an average of 134,000 acre-feet per annum the last five years, and that present duty for irrigation ])uri)oses is ai)i)roximately 1.3 acre-feet per acre per annum. Years of subnormal rainfall such as 1923-24, 1928-29. and 1930-31 show quite av>parent increases in pumping draft as will be observed by reference to the plate on i)age 12 and tables 2 and 8. 32 DIVISION OF WATER RESOURCES TABLE 8 ESTIMATED PUMPING DRAFT ON GROUND WATER BASIN OF SANTA CLARA VALLEY (See also plate on page 12) Acre-feet per annum Year "By San Jose \\'ater Co.

Ill 1914, 1915 and 191t) the United states Ueoluj^ical Survey took llie depth to ground Avater' in .some 1000 wells fairly well distributed throug'hout Santa Clara Valley as far south as Madrone, the records for which are available in Water Supply Paper 519. Again in 1920-21 Tibbetts and Xietfcr took the depth to ground water in a greater num- ber of wells, likewise fairl}- well distributed throughout this area, and Mr. Tibbetts has made the records of these measurements available to the Division. Since tiie inception of this investigation the Division has itself taken the depth in .some 2(i() wells in this area immediately before pumping for irrigation started eaeh spring and as promptly as i)rac- tieable after pumping for irrigation ceased each fall. With these data and thr ronliiiuous recoi'ds made available to the Division for interven- ing periods in a few wells it has been possible to plat with a fair degree of accurracy a hydrograph showing the general fluctuation of ground water level in Santa (Mara Valley at the close of each irrigation seastni since 1915. On page 12 there may be found a plati' on which is shown not only this hydrograph but a residual mass diacrram of rainfall and a graphic representation of the estimated j)um|)iiig draft basetl upon jiower consumption. It will be observed by reference to this plate that there has been a gradual but very marked recession in ground water lc\-cl in Santa Clara N'alley since 1!)15, intermitted only during those SANTA CLARA INVi;STIGAT[ON 33 pcriocls wlit'ii iMiiifall was at or above normal. Tlu' net ' recession in -round water level outside tiie artesian zone and north of Coyote Sta- tion, during the IS-year period (Sprinji of 1915 to Spring of 1933) as (.leterniined from contour maps of ground water elevation, amounts to a net total of 95 feet, oi- an average of slightlj- more than 5 feet per year, but during the years 1915-16, 1920-23, 1925-27, and 1931-32, when precipitation was normal or slightly above, the hydrograph indi- cates some recovery of ground water level. The year 1918-19 appears to be the only exception to the rule that ground water rose whenever precipitation was at or above normal, and the reason is not clear, but it is worthy of observation that in this year one-third of the total pre- cipitation occurred in a single period of four days. The Recession in Ground Water Storage. A change in the water level of an underground storage basin is inevitable whenever the conditions of draft or replenishment are dis- turbed and therefore a recession in ground water level does not neces- sarily indicate an overdraft; i.e., a pumping draft which exceeds the i-eplenishment. For any given set of conditions as to draft and replen- ishment a certain level of the groiiiul water is ultimately established and will thereafter be maintained. If draft exceeds replenishment the reserve storage will ultimately become exhausted. If replenishment exceeds draft the storage in reserve will increase until spill or waste from the basin occurs. As the excess of replenishment over draft increases the ground water in the basin continues to rise until a position is reached where the gradient (i.e., slope) of the ground water surface between points of recharge and points of discharge is just sufficient to cause the flow required to waste the excess. When the excess of replen- ishment over draft is reduced then ground water falls and this gradient is again reduced until a new balance is struck at which waste will again equal the diiference between replenishment and draft. The fact that there has been a recession of the ground water level in Santa Clara Valley in recent years therefore does not in itself prove that the draft under )iormal conditions will over a period of years exceed replenish- ment. The water level would have fallen in Santa Clara Valley in recent years had there been no pumping and it may be expected to rise again when a series of years of normal rainfall occurs in spite of the pumping. It will not. however, rise to its foi-mer level because of the increased pumping. The water in an underground storage basin is held between the l)articles of gravel, sand and clay and not only the capacity of any given ^ The recession in general g-round water level as determined by comparison of contour maps of ground water elevation differs from that estimated by comparison of the average depth to ground water in the wells due to the unevenness in distribu- tion of wells throughout the valley. 3 — 3390 :U DIVISION OP WATER RESOTTRCES u CQ < h H < X a: a a. < D z < -1 > u .J < u z u O w O r^ is I o >. q: wO -> ^ < 7 a, u 1 i cm 2 « ■S tr. > « M be B a So = 5 — C6 o o o ^ -J f5 + + + + + + 1 CO + Oi •o r^ o t^ OO „ to >oo o o — o 'T O odo •^o ^'o e< o 1 o c«g Ol o 1 => 1 m 1 oo 1 ^ 1 ■» 1 to 1 ^ 1 •«• to ' rt" 1 a to CO 1 ' V 1 7 !

In order to estimate the (•a|)aeity of an underjrround storaire basin, or wiiat tin; ehan<::es in water level tliei-ein actually represent in the way of storage increment or decrement, it is therefore necessary to establish not only the <;ross volume of the basin affected by the change, but the specific yield thereof; i.e., the relation of the amount of water given np and recoveretl by the voiding' and replenishnieiil to the volume of alluvial till atfected. In order to establish specific yield the logs of 112 wells fairly well distributed throughout the surface area of the ground water basin were ^analyzed, particularly with reference to the 100 feet of their depth lying within the zone affected by changes in water level in recent years, the material being classified into seven gi'oups as follows: clay, sandy clay, gravelly clay, light or fine sand, sand, tight gravel, and gravel. There is considerable lack of uniformity in the materials and struc- ture forming the underground storage basin of Santa Clara Valley, arising out of the origin thereof and the conditions of deposit. To properly evaluate these variations the basin was divided into zones and again into groui)S which are shown u])()n the contour maps of water levels accompanying this report. Zone A, on the basis of distribution of thick clay blankets and formei- artesian conditions, is considered to be a pressure area. Zone BC is marginal between the pressure area and the nonpressure area. During? periods of high water level the pressure area extends out into this zone, and in places may almost cross it. In general, changes in Zone BC probabh' represent changes of storage. Zone DE is the outer zone, nearest the valley margin and probably lies wholly outside the pressure area even during periods of high water level, so that changes of water level represent changes of storage in this zone. The area was divided also into four groups. Group I lies we.st of San Tomas Creek and comprises the alluvial cones of the small streams northwest of Los Gatos Creek. Group II comprises the alluvial cones of Los Gatos Creek, Guadalupe River, and a small part of Coyote cone between San Jose and the hills on the west side of the river. Group 1 1 1 comprises the Coyote cone above the narrows at Lick Station. Group IV comprises the area between Coyote River and the hills along the northeast side of the valley. It is believed that in typical gravel cone deposits formed under conditions of deposition comjiarable to those of Santa Clara Valley, little sand and practically no clay is deposited on the upper slopes, which correspond roughly to the area outside the pressure zone in the • By RoUin Eckis, Assistant Engineer, Geologi.st of the Division Staff. 36 DIVISION OP WATER RESOITRCES Sjuita Clara X'allcy. The ori-iinal deposits contain practically nothing but sand and gravel. The tight gravel, gravelly clay, and clay are derived by alteration of the gravels. It is believed that every gradation exists between the yield of good unaltered gravel aiul true clay which has no yield. The relative yields were accordingly divided equally, clay being placed at one end of the series with a relative yield factor of and gravel being placed at the other end with a relative yield factor of 3. The relative yields thus determined for the various zones were further modified by a location factor to correct for the ditference in yield between materials of the same classification located in the BC and 13E zones, because of the increase in yield as the slope of the alluvial cone flattens, a location factor of 4 being given to the BC zone and a location factor of 3 being given to the DE zone. Group III for which no logs were available and no relative yield values were computed, appears to be more similar to the adjacent Zone BC, than to Zo)ie DE, and therefore its relative yield probably approaches that of Zone BC. Tentative estimates were made for the specific yield values in the various zone groups by making use of values determined for alluvial materials in the South Coastal Basin where an exhaustive study by the Division is now being concluded. The specific yields for the various zone groups thus determined were then applied to the gross volume of alluvial fill saturated or voided as the water level raised or lowered between successive readings of the wells, the gross volume thus saturated or voided being determined, as stated above, by comparison of the ground water contour maps rather than by averaging the depths to water in the various wells. Zone A being artesian the fluctuations of ground water levels therein have been taken as significant of changes in pressure and not as significant of changes in gr-ouiul water .storage. It is true there ai)i)ears to have been an actual long time depletion of the stored water in tlie uppei" strata of Zone A, accompanying the reduction in the pres- sure beneath, but this must have been small and estimation of storage changes would necessarily refpiire information as to the fluctuation of watei- levels in shallow wells which is not availabhv There is also some fluctuation in ground water storage between Zone DE and Ihe hills for which no estimate can be made because of lack of information as to water levels in wells of that area. Offsetting the.se two factors which would tend to make any estimate of storage fluctuation too low is the fact that wells in part of Zone BC are nioi-e or less subject to artesian influence and therefore the fluctua- tions therein iht not truly represent changes in storage. It is believed SANTA cr.AKA INVKSTKiATION 37 that tlu'se three uiKleteniiiiu'd tactoi-s niori' or less olVset eueli oilier and that no prross error will be introdueed if all are ij?nored. Upon this assumption, and the other assunii)tions noted above as to specific yield in the various zone jrroups, tlie fipures shown in Table !) are submitted as representing: the best practicable estimate of the fluctuations since 1915 of the ground water in storage underlying Santa Clara Valley nortli of Coyote Station. The specific yield in the alluvial fill as thus determined varies between 7.3 per cent and 12.1 per cent in different zone groujjs with an average for the whole valley somewhat lower than estimated in Water Supply Paper 519 of the U. S. Geological Survey and in the Tibbetts- Kieffer report. Admittedly the information on which to base an esti- mate is meager and some assumptions are re(|uired in connection with which opinion may Avell differ, but the differences do not appear so great as to materially affect conclusions as to volume of change in ground water storage, and will eei-tainly not affect final eonelusions aw to overdraft. It would a])iiear jirobable that the general lowering of some 95 feet which occurred in water level in Santa Clara Valley dui-- ing the 18 years 1915 to 1933 represents a decrease of approximately 729.000 acre-feet in ground water storage reserve, or an average decre- ment of 40,000 acre-feet per year, which is roughly 8000 acre-feet for each one foot change in water level. This recession in ground water storage should, however, be inter- preted in the light of knoA\ni conditions as to draft and replenishment and to facilitate such an interpretation the variations of rainfall, pump- ing draft, and ground water level are shown for each yeai' since 1915 on the plate at page 12. The residual mass diagraiii of i-ainfall on this plate eovei-s the period 1874 to date and i-epresents eumulativf departure from mean. The hydrograph of general water level throughout the valley covers the period 1915 to 1932 during which wells have been under observation. The records of a few Avells are available continuously throughout this period and these wells were used as an index of the annual fluctuations between 1915, 1921, and 1930-33 in which vears manv wells were read, 7 7 * • it being found that fluctuation in these few wells during the intervals corresponded quite closely with the fluctuation in general level as reflected by the reading of the larger group in the years named. At the bottom of the plate the estimated pumping draft is shown graph- ically for each year, the estimates having been prepared as described on page 31. It \\ill be observed that the rt^idual mass diagram of rainfall and the hydrograph of general water level show a marked conformity, the one generally taking a precipitous slope or flattening out whenever the 38 DIVISIOX OF WATEK RESOURCES other doas. Thus, during the year December, 1930, to December, 1931, the general level of ground water in Santa Clara Valley fell 11.6 feet, which represents a decrement in the storage reserve of roughly 95,000 acre-feet and is in conformity with precipitation July 1, 1930, to July 1, 1931, which was only 50 per cent of normal, while general ground water level recovered 5.2 feet during the succeeding year (December, 1931, to December, 1932), which represents an accretion of roughly 44,000 acre-feet to underground storage, and is in conformity with precipitation July 1, 1931, to July 1, 1932, which was 5 per cent above normal. Likewise it will be observed that there was a marked recovery in ground Avater storage reserve during the years 1915-16 with precipi- tation 15 per cent above normal, and during the years 1920 to 1923, and 1!)25 to 1927 in which periods the rainfall was substantially normal. During the 17-year period 191.") to 1932 there was a deficiency in rainfall in Santa Clara Valley equivalent to the loss of 2^ full years of normal rainfall and Ihe deficiency in stream flow entering the valley was equivalent to the loss of 6.7 yeai-s of normal flow, while the pump- ing draft increased more than four fold. These major changes in the two factors which establish and maintain the balance in reserve storage at a given level are of course the causes of the recession in ground water level and the decrement in storage reserve. Analysis of available data as represented in the plate referred to above indicates, however, that ground water replenishment in Santa Clara Valley has exceeded draft during years of normal precipitation. Natural Sources of Ground Water Replenishment. Replenisliment of underground storage reservoirs is accomplished naturally uiidci- ordinai-y circumstances by penetration of rainfall upon the valley flooi-. l)y Interal ]")ereolation of rainfall precipitated ui)oii ad.jacent slopes, by percolation from streams traversing the valley and by leakau'c from ad.jacent basins. Replenishment can be stimulated cither by ])i'()longing the period of flow in streams traversing the valley or by spreading surface stream fll. 2, Xo. 6) that there is no material contribution to the ground water by direct penetra- tion of raiid'all upon ordinary .soils in the central portion of the valley. SANTA CLARA IXVKSTTOATION 39 The iH'i)ort of these tests by llic Division of Airi"it'ullui"al Eiitiinecrin^ w ill be found as Appendix E. It appears probable however that i)lant transpiration, evaporation, and siirfaee run-olf do not dis})0se of all rainfall precipitated on mar- :j:inal areas of Santa Clara Valley where the rainfall is greatest, and that there is percolation of rainfall to ground water in these areas and probably also along stream channels, and at points where there is an aeeuniulation of rain water upon the ground surface during storms or where irrigation water is applied in considerable quantities. Streams travei^sing the valley are major contributor to the ground water supi)ly and it is possible with the aid of the records of measure- ments made on Coyote River since 1902 (Appendices C and D) to estimate within reasonable limits what the contribution has been from this source. Percolation losses observed on this stream (Table 11) indi- cate an absorption capacity of *]53 second-feet between Madrone and San Jose at fairly low stages, practically all of Avhich is above Edenvale and therefore a source of replenishment for the underground storage basin of Santa Clara Valley. Percolation losses are greater at begin- ning of storm periods and at high stages. It is estimated (Table 10) that the average contribution of Coyote Kiver to ground water in a j^eriod of normal precipitation approximates 2:}.000 acre-feet per annum. Although a considerable proportion of this occurs above the Lower Gorge (Coyote) the ground Avater contour map accompanying this report indicates that such of this as is not with- drawn above by pumping must escape underground to the north through the Lower Gorge which has a very open formation with cross- sectional area of some **83.000 squaro fi'Pt below Ln'ound water level, and a gradient of 50 feet per mile. The total contributions of the remaining streams of the valley are not readily estimated because of accretions to flow and diversions between the upper and lower gaging stations. During the course of the present investigation the Division has, however, made a large number of measurements on these streams, for the purpose of establishing the best percolating areas and estimating the rate at which these will absorb. These measurements are reported in Appendix D and a sum- marA- of the data is assembled in Table 11 which indicates the total obsen'ed absorption on each stream and the rate of absorption per mile of stream channel and per acre flooded. The measurements were made generally at low stages near the close of flood periods and the total of 332 second-feet is therefore deemed a low figure, rather than an average. • study of percolation losses on Coyote River indicates a high rate of absorp- tion during the first few days of stream flow diminishing materially later in the season. •* Information as to cross-sect innal area and formation taken from copy of Def.

Artificial Sources of Ground Water Replenishment. Santa Clara Valley Conservation District has in recent j^ears done considerable work to stimulate additional percolation to ground water by the construction of spreading works on the valley floor both within and without the natural .stream cliannels and by the construction of small detention dams in the mountain areas with a view to flattening flood crests and thereby lengthening the period of flow in the valley. This Avork is described in Mr. Tibbetts' report of October 2, 1931, here- lot'ore referred to, as is also the ])lan of the District to construct addi- tional spreading works and surface storage of considerable magnitude in the upper reaches of the streams. When preparing their report to the Santa Clara Valley Water Conservation Committee IMessrs. F. II. Tibbetts and Stephen E. Kieffer made an extensive investigation of surface reservoir sites. Their report of March, 1921, describes 14 sites on streams which are tributary to the area embraced within Santa Clara Valley Water Conservation District, and are shown on the accompanying general map.

Substantially all oi' the flow passint; Edciivale in Coyote River escapes to San Francisco Bay as waste. While the percolation measure- ments made and re{)orted in Appendix D indicate some loss below Eden- vale this loss is offset by accretions. With surface storage and spread- ing- works of sufficient capacity the whole of the discharge at Edenvale could be conserved but this is of course not economically feasible. Examination of the records of the daily flow at Edenvale affords the best basis for an estimate of what amount of waste can be conserved on Coyote River with practicable facilities of various capacities. There is a record of the daily discharge at Edenvale since October 1, 1916, and by comparison with the Madrone record and the record at Sunol on Alameda Creek during periods of simultaneous discharge the Edenvale daily r(»cord has been extended backward to (ktober 1, 1902. This extended record of daily flow at Edenvale has been analyzed for each day of the 30-year period October 1, 1902, to September 30, 1932, to ascertain what amounts of waste could have been conserved either by surface storage of different capacities with varying rates of draft, or by increased percolation and diversion at varying rates with- out surface storage. The conclusions derived from this analysis are set down in tables 12 and 15. Tt is concluded from tliis analysis that over a cycle of years with normal i)recipitation, such as 1903 to 1926. the average annual wa.stc conservable on Coyote River with 30,000 acre-feet of surface storage capacity and no losses by evaporation from reservoir surfaces, would vary between 21,700 aiul 2.").S()() aere-feet depending upon the rate of draft during and between storms, that the conservable waste under similar conditions for 60,000 acre-feet of surface .storage capacity would vary between 30,200 and 36,000 acre-feet per annum; for 90,000 acre- feet surface storage cai)acity between 34.000 and 44,200 acre-feet per annum; and for 120,000 acre- feet of surface storage between 36,600 and 49,800 acre-feet per annum. This analysis leads to the fiiitliei- conclusion that without surface storage during a c.vcle of years of normal precipitation sucli as 1903- 1926 an average of 9400 acre-feet per year eoiild have been conserved on Coyote River had it been jiracticable to construct facilities to increa.se the percolation and diversion late by TOO second-feet; 12,500 acre-feet per year could have been con.served by increasing the percolation and diversion rate !.'")() se(*ond-f,000 aere-feet per year could have RANTA rivARA TXVKSTTOATTOX 4\i l)('(Mi eonservt'd by iiicreasinjj: tho percolation and diversion rate 200 second-feet (Table 15).

Th.' results of this analysis are shoAvn in Table 14. It is estimated IliMt wilh 50 second-feet increase in capacity 4200 acre-feet or 18 per cent of the conservable waste could have been saved during the period January 1, 1930, to March 31, 1933; with 100 second-feet increase in capacity 6800 acre-feet or 28 per cent could have been saved ; and with 150 second-feet increase in cai)aeity S600 acre-feet or 36 per cent could have been saved. Conservable Waste on Los Gatos Creek. There are no known practicable surface reservoir sites on Los Gatos Creek and in order to estimate the conservable waste from this stream the daily record of discharge at Los Gatos was analyzed for the period January 1, 1930. to March 31, 1933, under the assumption that 150 second-feet were re(|uired out of the flow originating above Los Gatos, in addition to local accretions, to satisfy present percolation and diver- sions, the remainder wasting into the ocean. Under this a.ssumption it is estimated as shown in Table 14 that on Los Gatos Creek during the period .l.imuny 1. 1I):!(), to March 31, 1933, 2500 acre-feet or 14 per cent of the assumed maximum conservable waste could have been conserved with 50 second-feet additional j)ercolation and diversion capacity. 4200 acre-feet or 23 pei- cent with 100 second-feet increase in capacity, and 5600 acre-feet or 31 |)er cent with 150 second-feet increa.se in capacity. * Almnden fiiul Calero Re.<»ervoirs are assumed to operate as a unit and it is a inatttT <>f i-hoicc which should receive credit for a portion of the water conserved.

Substantially all waste originating above the valley floor during the iH'riod January 1, 1980, to March 31, 1933, could have been con- served without increasing present percolation and diversion capacity by operation of a reservoir of 1400 acre-feet capacity, provided the present percolation and diversion capacity is not less than 40 second- f(M-t. Conservable Waste on Minor Streams. Tlie inflow to the valley and the surface waste by other minor streams were measured for at lea.st a portion of the year 1931-32, as reported in Appendix D and these daily records have been expanded to cover the full year by comparison with Coyote River, Gnadalupe River, Alamitos Creek, Los Gatos Creek and Stevens Creek records, which are complete for the year. This expanded daily record for each of the minor streams has been analyzed with a view to determining what amounts could have been conserved in 1931-32 by increasing the present rates of percolation and diversion. The results of this analysis are presented in Table 15 and for purposes of ready comparison the esti- mated amounts conservable during the same period on the larger streams are shown therewith. Under the assumptions which are noted in this table it is indicated that the amount conserved in 1931-32 on San Antonio Creek, Permanente Creek, Campbell Creek, Penitencia Creek, and Berryessa Creek would have ranged between 2200 acre-feet or 33 per cent of the total conservable waste and 4800 acre-feet or 71 per cent, depending upon the increase in facilities for percolation and diversion. Conservation of Local Waste Sufficient. In t'stiiiiatiiig the amount of waste which it is practicable to con- serve without surface storage, an effort has been made to apply assump- tions which would lead to outside figures for each individual stream; i.e., a conservative minimum figure and a maximum figure which might be expected in the way of conservation on each stream were it alone developed. i\raximum figures should not be taken on all streams.

At the time of making this test It was believed that conditions were as nearly stable as they were ever likely to be. The stage at Loyola remained con- stant until late in the afternoon of January 16th and no pumps were operating between the two stations during the pro- gress of the test. A small quantity of water had been allowed to pass the Permanente Dam in the forenoon but throughout the test the entire stream was being diverted at this point. 104 DIVISION OF WATER RESOURCES PERCOLATION TESTS ON STEVENS CREEK Location of Measuring Stations — Station No. 1 — 60 feet upstream from McLellan Road Bridge.

The diversion to the .Masson Ditch (Station 13) is considered. Test 6 represents a single set of measurements. Conditions were excellent and the results should be reliable. Some two acres of the area between Stations 18 and 19 consists of a gravel pit in which silting has occurred, probably account- ing for the small observed loss in this section; station 24 represents the point of complete absorption. Test 7 represents single sets of tte.asurements. Station 25 represents the point of complete absorption February 20. The loss indicated between Stations 23 and 25 is doubtful due to the rapiditv of recession of the stream, and is prob- ably too small. The distance downstream from Station 20 (Test 6) to Station 21 (Test 7) is 155 feet: Station 24 (Test 6)) is 400 feet downstream from Station 20 (Test 6) hence Tests 6 and 7 overlap 245 feet. Within this 245 feet section there is an exceedingly porous spot where the loss is apparent to the eye. Test 6 includes only 0.26 acres of this porous spot while Test 7, Stations 21 to 25, includes 3.83 acres and Station 21 to 26 includes 2.48 acres. The diversion at Stotion 22 is considered.

Note— In an unpublished report of field work done by R. L. Egenhoff in connection with 0. E. S. Bulletin 254 of the l". S. Department of .\griculture, it is indicated that this ditch diverted up to 13 second feet in 1912 and that 11 sec- ond feet failed after 12 hours diversion to appear at a point 2 miles down the ditch. Mr Egenhoff estimated that 50 per cent of the diversions to the Masson Ranch properties wa.s lost by percolation from the ditch and that 75 per cent of the diversions to properties below the Masson Ranch were lost by seepage from the main ditch and laterals. PERCOLATION TESTS ON DUNCAN DITCH AND FINNEMORES SINK HOLE NO. 2 Duncan Ditch- No percolation measurements were made on Duncan Ditch itself but it is a feeder of Finnemore's Sink Hole No. 2 which can be used as a spreading ground. The measured discharge into this sink hole on December 30, 1931 was 18.97 second feet and the estimated capacity of the ditch itself is 30 second feet. Finnemore's Sink Hole No. 2 — This so-called sink hole is an old gravel pit located on the east bank of Los Gatos Creek fust south of Ca.spy Road. It is dei^ignated as "No. 2" becau.se another pit exists on Finnemore's property upon which a percolation test had been attempted at an earlier date and abandoned because of the inconstancy of the water level in the pit. The spillway from the Duncan Ditch empties into this No. 2 pit and apparently a balance can be maintained between discharge from the spillwav and absorption in the pit. A discharge measurement was made at the spillway and the area of the pit determined by stadia on January 8, 1932. The flooded area was 1.115 acres and the discharge of 5.93 second feet into the pit was apparently all being absorbed thus indicating an absorption rate of 5.32 second feet per acre. The accuracy of this absorption rate depends largely upon the correctness of the statement made byNIr. W. Finne- more that the water level in the pit remained unchanged for one week and that the dbcharge from the spillway was like- wise constant. .f APPENDIX E RAINFALL PENETRATION DATA SANTA CLARA INVESTIGATION ll!7 RAINFALL PENETRATION IN THE SA2iTA CLARA VALLEY By O. A. Taylok April, 19:10. A general survey of tlie Santa Clara Valley was made April t to ti, 1930, with regard to the possibility of direct penetration of rainfall on the valley floor. Thirty- one holes were drilled and notes taken on iiiDistiire conditions and soil type. It was inte!idfd that -samples be obtained to depths of twenty-four feet but this was not always possible as rook fragments were usually encountered that liniited tln' (U-iJth of the hole. The data from each location are appended. The soil on the valley floor is generally of a loam or heavier texture, riant roots penetrate to considerable depths and create a large deficiency in soil moisture at the end of the .smnmer season. This is especially true in deciduous orchards which predominate on the valley floor. Veihmeyer, (Veihmeyer, F. J., Some Factors Affecting the Irrigation Requirements of Deciduous Orchards, Hilgardia Vol. 2, No. 6, January, 1927, Page 157, Table 5) indicates that the fall deficiency in soil moisture below field capacity in mature prune orchards is very close to 12 acre- inches per acre in the upper 12 feet of soil. Cover crops are usually grown during the winter, and the loss by evaporation and transpiration during the rainy seas(jn is probably not less than 8 acre-inches per acre. It would seem therefore that upwards of 20 inches of rain would be required before direct penetration of rain is at all likely to occur in the deciduous orchards of this area. A certain few heavily irrigated orchards were found to be wet through the full depth of the root zone, but mucli of the deep i>ercolation here should be charged to return waters resulting from over Irrigation. The soil is deep ; the crops are mainly deep rooted deciduous ; the topography is relatively flat ; and considering these factors irrigation practice sliould be such that practically all of the normal rainfall available for storage is held within the root zone. Cover crops that are. left until late in March consume a large amount of moisture. It was estimated that some of the cover crops would use upwards of 3.0 acre-inches per acre per month in the late spring. It is obvious then that cover crops left in after the middle of February must necessarily have a consid- erable cost of water charged against them. Samples in the Milpitas Area, seven miles north of San Jose, showed no dry soil within the root zone. However, the soil in that area is typically a heavy clay, so that it is questionable if rainfall penetrates through to the pumping stratas. In conclusion, it is thought that normal rainfall on the Santa Clara Valley floor does not contribute materially to the undei'ground water Kui)ply by direct penetration through the root zone. A more beneficial use of the water supply from rainfall should be secured by discing in the co\er crops earlier, even though it be at the exjjense of some fertilizer value.
