' *- PUF^POSE AND SCOPE OF THE STUDI The desert areas of southern California, of vhich the Cl:ucl:;ra,lla Valley area is a part (fig. l), are broad va?J.eys or "basins that have been partly filled by alluvial deposits and are surrounded by nearly ban-en mountain ranges. These basins contain ground water that varies widely in chemical quality and is potentially available for development for irrigation, industrial, and domestic supply. The objective of the investigation was the collection and tabulation of all available hydrologic data for use in planning orderly development and utilization of the ground-water resources, as well as providing a basis for subsequent detailed ground-water studies. Fieldwork by the U.S. Geological Sunrey in the area included: (l) A very brief reconnaissance of the ma^or geologic features to define the extent and General character of the deposits that contain ground crater; (2) an inventory and exarination of virtually all the vater wells in the area to detennine and record their locations in relation to geographic and ciatural features and the public-land net, and to record the depths and sizes of the -wells, the types and capacities of installed pvimping equipnent, uses of the water, and other pertinent information; (3) the measurement and recording of the depth to the water surface in wells, below established and described measxiring points at or near the land surface; (h) the selection of representative wells and the periodic measurements of Tjater level in these wells in order to detect changes of water levels; and (5) the collection and compilation of well records, including well logs, water-level measurements, and chemical analyses. This study has been made by the U.S. Department of the Interior, Geological Survey, as a part of the cooperative program with the California Department of IJater Resources to investigate the ground- water resources of the desert areas. Fieldwork and preparation of the report have been under the general supervision of H. D. Wilson, Jr., and Fred Kunkel, successively district engineer and district geologist in charge of ground-v;ater investigations in California, and under the immediate supervision of G. M. Hogenson, geologist in charge of the Long Beach subdistrict office. LOCATION Airo GEflERAL FEATURES OP THE AREA The C3auckwalla Valley area, as described in this report (fig. l), includes about l,l60 square miles. The area of this study lies in the desert region of southern California between long, llk''k6^ and 115''l4-5' U. and lat 33''28' and 34'*C2' N. The boundaries are shc'ra on figures 1, 2, and 3. The area includes all or parts of the follo'\-d.ng U.S. Geological Survey and Army Map Service topographic quadrangle maps at a scale of 1:62,500: Cadiz Valley, Canyon Spring, Chuckvralla Mountains, Chuclaralla Spring, Coxcomb Mo-ontain, Iron Mountains, McCoy Spring, Midland, Palen Mountains, Palo Verde Mountains, and Sidewinder Iv'ell. (See index naps of figs. 2 and 3.) Access to the area is provided by U.S. Highway 6O-7O and the Parker Dam Higiiway. The Ciiuckvralla Valley is a desert area of internal drainage with no perennial streams. It consists of a broad alluviated valley bounded on the south by the Orocopia Mountains, Chuckwalla Mountains, Little Cliuclcwalla Mountains, and Mule Mountains. It is bovmded on the west by the Eagle Mountains and on the east by the Jiule Mountains and McCoy Mountains, Several northerly trending mountain ranges, the Coxcomb Mountains, Granite Mountains, Palen Mountains, and Little Maria Mountains, bound the valley to the north and extend into the valley. The intervening valleys are contiguous with and tributary to the main part of Chuckwalla Valley. GEOLOGIC AM) HYDEOLOGIC i-TIATI^KaS The geologic units in the Q:ucl^falla Valley area can be grouped into tiro broad categories: consolidated rocks and imconsolidated deposits. The consolidated rocks include the metaciorphic and igneous intrusive rocks of pre -Tertiary age that form the basenent con^lex. In some localities, the consolidated rocks include volcanic rocks of Tertiary age that overlie the basement complex. For the most part, the consolidated rocks are not irater bearing, except for minor amounts of water contained in cracks and residu"am. The unconsolidated deposits consist of sedimentary material that was deposited in a continental environment, mainly during Quaternary time. Some of the sedimentary rocks may be as old as late Tertiary. Most of the material was waterlain as alluvial-fan, stream- channel, lake or playa deposits, but some of the sand was deposited by wind. Included in the unconsolidated deposits are the Pinto Formation of Scharf (1935, P« 11-20), older alluvium, lacustrine deposits, and fan deposits, all of Pleistocene age, and younger alluvium, playa deposits, and windblown sand, all of Recent age, . . The lacustrine deposits of Pleistocene age are shown on figures 2 and 3 2nd consist mainly of bentonitic clay interbedded with very fine sand and silt. The deposi.ts are flat.lying, moderately indurated, and appear to be locally gypsiferous with numeroi^s sandy oblong concretions present in the clay. The extent of dissection varies with the location. The e>5)o&ures northwest of Palen La::e consist maj.nly of mesa-type prominences varying in height from 5 to 10 feet. In this locality the deposits are capped with a surface of caliche and support scattered areas of mesquite. The deposits overlain by the alluvial fans e:-ctending south from the Palen Mountains are believed to be more extensive than is saovm on figure 2. If the alluvial fans were dissected to greater depths, the lacustrine deposits would be exposed over a greater lateral area. The lacustrine deposits are differentiated from the overlying alluvial fans by the absence of coarse fragmental material and the presence of thick beds of pinkish clay. These deposits would probably yield only small amounts of water to wells. Scharf's Pinto Toniation, of Pleistocene age, is shown on figure 3. This formation consists mainly of coarse bouldery fanglomerate and lacustrine clay, with some interbedded basalt. The fanglomerate deposit probably would yield water freely to wells, but the basalt probably would yield only small amounts of water. Tbe older alluvium is of Pleistocene age and is shown on figure 2. It consists of fine to coarse sand interbedded with gravel, silt, and clay. Tlie color of the deposit ranges from dark brovm to i-ed, with a speckled appearance caused by numerous small whits nodules of caliche. Hie deposit apparently is extensive, but surface exposures are limited to a few gravel pits where the overljrLng deposits of younger alluviimi and windbloim sand have been removed. The older alluviiim yields water freely to wells and probably is the most important aquifer in the area. The fan deposits of Pleistocene age, which are sho^m on figures 2 and 3, are poorly sorted and consist of boulders, ver^r coarse to fine gravel, sand, silt, and clay. The fans are characterized by local areas of well- developed desert pavement. This deposit is generally above the water table and is not considered a ijater-bearing miit. TJhere saturated, the fan deposits nay yield small amounts of water to wells. Tlie younger alluvium of Recent age, which is sho\m on figures 2 and 3, is poorly sorted and consists of gravel, sand, silt, and clay. This permeable deposit overlies many of the geologic vmits in aiucfc/alla Valley as a thin veneer and is believed to be mostly above the water table. If saturated, this deposit probably would yield water freely to wells. The playa deposits of Recent age, which are shovm on figures 2 and 3, consist mainly of clay, silt, and sand. Tliese deposits occur in three locations: Ford Lake, Eayfield Reservoir, and Palen Lake. Of the three playas, Palen Lake is probably the only playa which discharges ground water by evapotranspiration. The playa deposits are relatively impermeable and probably will not yield water readily to wells. The belt of iTindblcnm sand of Recent age, which is shotra on figures 2 and 3, consists of actively drifting sand and is a result of easterly and westerly irLnds. This unit mainly occupies the lov^er elevations of the valley from the northwest end of Chucta/alla Valley to the eastern linit of the mapped area. The deposit varies in thiclmess from to 25 feet. Some of the dunes are anchored by vegetation. This deposit apparently is abo\''e the water table and is not considered to be a water-bearing unit. "- -^^'^-^^^"^ -- ''■■--■^'2 - -- ••''•• In many of the desert valleys of soutliern California, the unconsolj.dated water-bearing alluvial deposits underlying the valley floors are displaced along faults, which impede the horizontal movement of ground ^iater. Such faults may be present in Chuckvralla Valley, but, if so, they are not apparent on aerial photographs or to field inspection. Also, pronounced differences in water levels within short horizontal distances, which suggest faulting of the water-bearing deposits, are not kno^m to be present. The ground-water supply in Chuclroalla Valley is replenished by ground-water inflca/ from Pinto Basin and by runoff from the slopes of the mountains surrounding the valley. Also, a small amount of recharge may originate from infrequent rain on the valley floor. ninety- t\TO veils and springs were inventoried in the Ch'ick\-ra.lla Valley- area. Data for these wells are listed in tables 1 through k, and the well locations are sho^.m on fig^-ires 2 and 3- Measured watsr levels range from U85 feet below land surface in well ^/iU-26A1, west of Desert Center, to 21 feet below land surface in well U-/Y[-6c1j north of Palen Lake. Examination of all water levels in the valley indicates a gro\xnd-water gradient from the Desert Center area eastward toward the gap betv/een the Mule Mountains and McCoy Mountains. The gradient is steeper in the western half of the valley and is nearly flat in the eastern part. Five wells have been selected as representative to show the range of long-term water-level fluctuations in different parts of the area. Complete published and unpublished records for wells k-/l6-3'2.ul, ^/17-6C1, and 5/16-810. are shown in table 2. Records for wells Vl6-29R1 s-i^d 7/20-UrI are sho\m in table 1. „•.:.-. ... 10 PREVIOUS WORK AND ACKI^'ClfflEDGMEi^TS Data on gro\ind vater and geology in Chuckvralla Valley are contained in reports by the Geological Survey (Brown, 1920, p. H5-67, and 1923, p. 101-106, 236-251, 26l-26i^; 272-273, 276, 230-283; Kunkel, 1956, pi, 1); California Department of Public Works (195^, p. ^O-'-vl, 59; 1956, p. 9-10, 33-3ij-, 51-56); California Departnent of Water Resources (1953, p. F-3; i960, p. F-2; I96I, p. D-2); Koppin (195^ pi. 1); and Scharf (1935, p. 11-20). The author expresses appreciation for the cooperation given by ranchers, ue3JL caraers, well drillerr., and other persons who furnished information for this investigation. The California Department of IJater Reso^irces and the Riverside County Flood Control District provided all the pertinent infonnation in their files, including well logs, water-level records, and chemical analyses. The cooperation and assistance given by these people and agencies contributed materially to the preparation of this report and are gratefully acknowledged. 11 iVELL-NTJlffiSP.IWG SYSTEiM The veil-numbering system used in the area described in this report has been used by the Geological Suirrey in California since I9U0. It has been adopted by the California Depart-Jienfc of Water Resources and by the California Water Pollution Control Board for use ' throughout the state. Wells are assigned numbers according to their location in the rectangular system for the subdivision of public land. For example^ in the number 5/l6-Tiyil the part of the number preceding the slash (/) indicates the tovnship (T. 5 3«)j the number follo-./:ing tlis slash indicates the range (R. 16 E.); "the niimber fo.ll,ovrij-.3 the h;yphen (-) indicates the section (sec. 7); the letter follo^rin^ the section number indicates the i+O-acre subdivision of the section as shOT^rn in the diagram below: . , D C B A E F G H M L K J W P Q R Within the UO-acre subdivision, the wells are numbered serially as indicated by the final digit. Thus, well 5/l6-7i^'Il is the first well to be listed in the NV('-^31'/■^■ sec. 7. 12 For well nuiobers where a Z has "been substituted for the letter designating the UO-acre subdivision, the Z indicates that the well is plotted from unverified location descriptions. The indicated sites of such wells were visited but no e-'/idence of e. we.\l coiild be found. -. , ,, • ■>■•"••; -::- ,.•".- Because the Chuclnrair.a Valley area is situated entirely within the southeast quadrant of the San Bernardino base and meridian, the tormship and range designations, as given, are adequate. In those instances where wells have been found to be J.ocated inaccurately and a number has been assigned previously, thej' have been correctly plotted on the map but the original numbers have been retained. This has been done to avoid the necessity for number changes in reports already published. Fortunately, these mislocated wells are few in number and were seldom misplaced any farther than one of the adjoining UO-acre subdivisions. Springs are numbered according to the same system as wells, except that the letter s has been substituted for the final digit in the number. . . _• ^ - 13 REFSRMCE3 CITED Brovn, J, S., 1920, Routes to desert vatering places in the Salton Sea region, California: U.S. Geol.

W. Glessner PURPOSE AND SCOPE OF THE STUDY The desert areas of southern California, of which the Rice and Vidfll Valleys are a part (fig. l), are broad valleys or basins that have been partly filled by alluvial deposits and are surrounded by nearly barren mountain ranges. These basins contain ground water that varies widely in chemical quality and is potentially available for development for irrigation, industrial, and domestic supply. The objective of the investigation was the collection and tabulation of all available hydrologic data for use in planning orderly development and utilization of the ground-water resources, as well as providing a basis for subsequent detailed ground-water studies. Fieldwork by the U.S. Geological Survey in the area included: (l) A very brief reconnaissance of the major geologic featxxres to define the extent euid general character of the deposits that contain ground vater; (2) an inventory and examination of virtually all the vater wells in the area to determine and record their locations in relation to geographic and cultviral features and the public-land net, and to record the depths and sizes of the wells, the types and capacities of installed pumping equipment, uses of the water, and other pertinent information; (3) the measurement and recording of the depth to the water surface in wells, below established and described measuring points at or near the land surface; (k) the selection of representative wells and the periodic measurements '^ of water level in these wells in order to detect changes of water levels; and (5) the collection and compilation of well records, including well logs, water-level measurements, and chemical ajialyses. This study has been made by the U.S. Department of the Interior, Geological Survey, as a part of the cooperative program with the California Department of Water Resources to Investigate the ground- water resources of the desert areas. Fieldwork and preparation of the report have been under the general supervision of Fred Kunkel, district geologist in charge of ground-water investigations in California, and under the Immediate svtpervision of G. M. Hogenson, geologist in charge of the Long Beach subdistrict office. LOCATION AIID GEJJIilRAL FEATURES OF THE AREA Rice and Vidal Valleys are located in the desert region of southern California betvreen long ll4*'30' and 114^57 ' W. and lat 33*'52' and Si+^EO' N. The boundaries as shovm on figures 1 and 2 include all or parts of the following U.S. Geological Swrvey and Army ^felp Service topographic quadrangle maps at a scale of 1:62,500: Big Maria Moiintains, Midland, Rice, Savahia Peak, Turtle Mountains, and Vidal. (See index map on fig. 2.) The total area of Rice and Vidal Valleys, as described in this report (fig. l), consists of about 710 square miles. Individually, the two valleys ajre approximately equal in area, each containing about 355 square miles. Access to the area is provided by U.S. Highway 95* the Parker Dam Highway and the unpaved Rice to Midland road. Rice Valley is an area of internal drainage with no perennial streams. It consists of a nearly circular alluviated valley bounded on the south by the Little Maria and the Big Maria Mountains. The western boundary is formed by the Arica Mountains which are separated frcm the Little Maria Mountains to the south and the Turtle Mountains to the north by low alluviated drainage divides. The Turtle Moiintains provide the northern boundary of the basin and are separated by an alluviated drainage divide from the West Riverside and Riverside Mountains which mark the eastern extent of the area. Vidal Valley is also an area of internal drainage with no perennial streams. It is a valley of irregular shape, boxinded on the south by the West Riverside and Riverside Mountains, on the west by the Turtle Mountains, and on the north by the Turtle and Whipple Mountains. The eastern boundary of the valley is formed by the Colorado River; hovrever, the area of study does not extend eastward to include this portion of the valley. The east edge of the Vidal quadrangle lies approximately 0.5 mile east of Vidal and is used to define the eastern boundary of the area of study. GEOLOGIC AND HYDROLOGIC FEATURES The geologic units in the Rice and Vidal Valley areas are grouped into two "broad categories: consolidated rocks and unconsolidated deposits. The consolidated rocks include the metamorphic and igneous intrusive rocks of pre-Tei-tiary age that form the basement complex, and some undifferentiated volcanic rocks of Tertiary(?) and Quatemary(?) age. The volcanic rocks consist mainly of hasalt flows. Sore are of felsic composition. The consolidated rocks are not water bearing, except for minor amounts of water contained in cracks and residuum. ^ r . • ■ The extent of the volcanic rocks, shown on figure 2, is based primarily on aerial photographs. Therefore, some areas designated as basement complex may be locally overlain by volcanic rooks. Also, isolated areas of basement complex may be included in the area niapped as volcanic rocks. -- - The unconsolidated deposits consist of sedimentary material deposited in a continental environment, mainly during Quaternary time. Most of the material was waterlain as alluvial- fan, stream- channel, lake, or playa deposits, but some of the sand was deposited by the wind. Six units, shown on figure 2, make up the unconsolidated rocks. These are the older alluvium, the lacustrine deposits, and the fan deposits, oXL of Pleistocene age; the younger alluvium, the pla,ya deposits, and the windblown sand, all of Recent age. The lacustrine deposits of Pleistocene age consist of 'bentoinitic clay interbedded with very fine sand and silt. The deposits are flat- lying, moderately indurated, and, locally, dissection has resulted in vertical exposures of as much as 50 feet. The absence of coarse f rag- mental material and the presence of clay interbedded with fine sand and silt differentiates the lacustrine deposits from the overlying alluvial fans. These deposits would probably yield only small amounts of water to wells. The older alluvium is of Pleistocene age and consists of fine to coarse sand interbedded with gravel, silt, and clay. The color ranges from dark brown to red, with n\imerous small wUite nodules of caliche which give it a speckled appearance. The older alluvium yields water freely to wells and probably is the most important aquifer in the area. The fan deposits of Pleistocene age are poorly sorted and consist of boulders, very coarse to fine gravel, sand, silt, and clay. The fans extend into the va3J.ey from the surrounding mountains and are characterized by local areas of well-developed desert pavement. This deposit is generally above the water table and is not considered to be a water-bearing unit. Where saturated, the fan deposits may yield small amovmts of water to wells. The younger alluvium of Recent age consists of poorly sorted gravel, sand, silt, and clay. This deposit is permeable, but it overlies many of the geologic units in the Rice and Vidal Valley areas as a thin veneer and is believed to be mostly above the water table. If saturated, the deposit probably would yield water freely to wells. 8 The playa deposits of Recent age consist mainly of clay, silt, and sand. They are relatively impermeable and probably will not yield water readily to wells. The windblown sand of Recent age consists of actively drif:!:ing sand and some dunes which are anchored by vegetation. This imit mainly occupies the lover elevations of the valleys and varies in thickness from to 15 feet. The deposit apparently is above the water table at all localities and is not considered to be a water- bearing unit. The source of recharge to Rice and Vidal Valleys is primarily precipitation that falls on the surrounding mountain ranges. Since the annual precipitation for this desert area is approximately three inches or less, the runoff from the adjacent mountains contributes only a small amount of recharge. Some of the surface runoff is lost due to,, evaporation, but some percolates into the unconsolidated deposits at the edges of the valley floors and is added to the ground-water basin. A small amount of ground water may enter Rice Valley as underground inflow from Ward Valley, an adjacent connecting valley. Tvrenty-eight wells and springs were inventoried in the Rice and Vidal Valley area. Data for these weLls and springs are listed in tables 1 through 3, and their locations are shown on figure 2. MeasTired water levels by the U.S. Geological Survey in Rice Valley range from 285 feet below land siirface in well 3S/21E-18D1 and l8l feet below land surface in well 2S/21E-28n1 to 151 feet below land surface in well 1S/21E-32B1. A small gradient toward the southeast is indicated by these three water-level measurements, and subsxirfacc outflow may occur from Rice Valley through the alluvial drainage divide between the Riverside Mountains and the Big Maria Mountains. Measured water levels in Vidal Valley range from 267 feet below land surface in well 1K/23E~8D1, near Vidal junction, to 2^1-6 feet below land surface in well 1N/23E-36R1 at Vidal. Three wells have been selected as representative to phow the range of long-term water-level fluctuations in different parts of the area. Co-j-r^lete records for wells 1S/21E-32B1, 1S/23E--JJ\.2, and 1N/23E-8D1 are shown in table 1. 10 PREVIOUS WORK AIJD ACKNOVLErGMEirrS Data on ground water and geology in Rice and Vidal Valleys are contained in reports by the Geological Survey (Brcwn, 1920, p. 63-65, and 1923, p. 99-101, 26O-26I, 280-233; Lee, I908, p. I8, 65-66; Mendenhall, I909, p. 79; Thompson, I929, p. 7II-715, 714.1-7^7); and the California Department of Public V/orks (195*^, p. 39, 46, 59). The cooperation given by well owners and other persons who furnished information for this investigation contributed materially to the preparation of this report and is gratefully aclinowledged. The California Department of Water Resources, the Riverside County Flood Control District, and the Ssji Bernardino County Flood Control District provided all the pertinent information in their files. I .1 -£ 11 WELIr-NUMBERIHG SYSTEM The well-numbering system iisecl in the area described in this report has been used by the Geological Svirvey in California since 19^0. It has been adopted by the California Department of Water Resoirrces and by the California Water pollution Control Board for use throughout the state. Wells are assigned numbers' according to their location in the rectangular system for the subdivision of public land. For example, in the nunber IN/23E-8DI the part of the number preceding the slarh (/) indicates the township (t. IN.); the number following the slash indicates the range (R. 23 E.)j the number following the hj-phen (-) indicates the section (sec. 8); the letter following the section nianber indicates the U-O-acre subdivision of the section as shown In the diagram below: D C B A E F G H M L K J N P Q R 12 Within the l4-0-acre BUbdivision, the wells are numbered serially as indicated by the final digit. Thus, well 1K/23E-8D1 is the first well to be listed in the NW-^KIW-^- sec. 8. Because the Rice and Vidal area is traversed hy the San Bernardino base and meridian, the letters N and S are used to indicate whether the well lies north or south of the base line. The letter E indicates that the entire area is east of the San Bernardino meridian. For well nvcnibers where a Z has been substituted for the letter designating the UO-acre subdivision, the Z indicates that the well is plotted from unverified location descriptions. The indicated sites of such wells were visited but no evidence of a well could be fovmd. Springs are numbered according to the same system as wells, except that the letter b has been substituted for the final digit in the number. 13 REF3RETCE3 CITED Brcfwn, J.
