Moyle, Jr. PURPOSE AND SCOPE OF THE WORK AND REPORT The data in this report were collected by the U.S. Geological Survey in connection with an investigation of water wells and gen- ersQ. hydrologic conditions throughout much of the desert region of southern California. The study was made in cooperation with the California Department of Water Resources. The desert regions of California are characteristiceilly regions of barren mountain ranges and isolated hills surrounding broad valleys or basins, which are underlain by alluvial debris derived from the mountains and hills. These basins generally con- tain ground water having a wide range in chemical quality, which could be and in some areas already has been developed for bene- ficial use. The general objectives of the cooperative investigation are the collection and tabulation of all available hydrologic data for the individual desert basins in order to provide public agencies and the general public with data for planning water utilization and development works and for use in possible subsequent ground- water investigations. Accordingly, the scope of the work carried out by the Geolog- ical Survey in each sirea has Included: (l) very brief reconnaissance of major geologic features to map the extent and define the general character of the deposits that contain the ground-water bodies; (2) visiting and examining practically all the water wells in the area; determining the locations of wells in relation to geographic and cultural features and the public-land net, wherever possible; and recording well depths and sizes, types and capacities of installed equipment, uses of the water, and other pertinent information available at the well site; (3) measurement of the depth to the water surface below an established measxiring point at or near the land surface; (h) selection of representative wells to be measured periodically in order to detect and record changes of water levels; and (5) collection and assemblage of well records, including well logs, water-level measurements, and chemical analyses. The work has been carried on by the U.S. Department of the Interior, Geological Survey, under the general supervision of H. D. Wilson, Jr., district engineer in charge of ground -water investi- gations in California, and under the immediate supervision of Fred Kunkel, geologist in charge of the Long Beach subdistrict office. The field work was carried on intermittently between June 1958 and July 1959 from the southern California subdistrict office of the Ground Water Branch at Long Beach. PREVIOUS WORK AND ACKJ^IOWLEDGMEKTS Data on ground water in the eastern part of the Mddle Itojave Valley area are contained in several U.S. Geological Survey water- supply papers, which are listed in table 3, California Department of Engineering Bulletin 5 (l9l8), California Division of Water Resources Bulletin kj (19314-), San Bernardino County Flood Control District I^ydrologic and Climatic Data volumes 2, 3, and h (1951^ 195^, and 1958), California Department of Water Resources Bulletin 39-57 (1958). The entire eastern part of the mddle Ivtojave Valley area is shown on a geologic map of the Barstow quadrangle by 0. E. Bowen, Jr., (195^+). The writers wish to express their appreciation for the co- operation, assistance, and information given by the many ranchers, well owners, drillers, and several public agencies during the investigation. LOCATION AND GENERAL FEATURES OF THE AREA The eastern part of the Middle Mojave Valley area as described in this report covers about 390 square miles and in general includes the eastern part of the Middle Mbjave Valley of Thompson (l929j pl- 17). Barstow, Hinkley, Johnson Comers, Eads, Hawes, and Jimgrey are the principal towns and communities in the area. The ajrea is in the southwestern part of the Mojave Desert region (fig. l) between long 117"*00' and 117 "30' W. and about lat Figure 1. Map of peirt of southern California showing axea covered by this report. 3l(."'38' and 35'*00' N. The eastern boundary corresponds to the eastern edge of the Barstow and Apple Valley topographic quad- rangle mapsj the western boundary corresponds to the approximate location of the Helendale fault and the eastern boundary of the west part of the Middle Mojave Valley area, after Page, toyle, and Dutcher (1959); the northern boundary of the area is the lat 35 "GO' N. line which is the northern edge of the Barstow and Hawes quad- rangle maps. The southern boundary of the area corresponds to the northern boundary of the Upper Mojave Valley area, after Bader, Page, and Dutcher (1958). The area is shown on all or psurts of the following U.S. Geo- logical Survey topographic quadrangle maps: Barstow, Hawes, and Apple Valley at a scale of 1:62,500; the Helendale quadrangle at a scale of l:2i»-,000; and the Barstow quadrangle at a scale of 1:125,000. Access to the area is provided by U.S. Highways 66 and h66, as well as several other paved and numerous unpaved roads. Geographically the area consists principally of broad allu- vial fans and gently sloping alluvial plains built out from the isolated mountains that rise to considerable heights above the valley floor. The area includes all of Hinkley Veilley and part of Harper Valley, the remainder of which has been described by Kunkel (1956). The remaining smaller valleys that make up the larger unit called the eastern part of the Middle Mojave Valley area do not appear to have definite geologic or hydrologic boundaries, but correspond rather to cultxiral units centered about the areas as shown on figure 2. Figure 2.

The consolidated rocks are for the most part impervious and, except for minor amounts of water in cracks and weathered zones, yield little or no water. The consoli- dated rocks (fig. 2) comprise the old crystalline, metamorphic, and consolidated sedimentary rocks of pre-tertiary age which collec- tively form the basement complex and the consolidated sedimentary rocks of Tertiary age. The consolidated sedimentary and pyroclastic rocks are of Tertiary age. They consist mainly of gray and red conglomerate, arkose, cobble gravel, tuff, sandstone, chert, limestone, gravel, sand, silt, and clay. For the most part these rocks are poorly permeable, but locally they yield sufficient water for domestic use to deep wells. Near the town of Barstow the unit consists of angular fragments of volcanic material having a lime and mud matrix. The h:'-drologic character of these roc"-?; is not kno\m, but on the basis of their appearance they are probably poorly per- meable and virtually not water bearing. Volcanic rocks of acidic composition, mainly andesite, rhyollte, and daclte of Miocene and Pliocene age, also occur in the eastern part of the Middle Mojave Valley area. The unconsolidated older alluvium of late Pleistocene age consists of compact arkosic gravel, sand, silt, and clay. The deposits are weathered, and locally the feldspeirs have been altered to clay. Near the hills the unit is predominantly gravel but beneath the valley areas it is finer grained and better sorted. Because the older alluvium overlies the basement complex, older fan deposits, or Tertiary continental rocks on vhich an erosional surface of considerable local relief is present, the thickness of the older alluvium veirles greatly from place to place. Where it is saturated the older alluvium yields moderate quantities of water to wells. The older fan deposits of Pleistocene age consist of slightly consolidated fanglomerate or unsorted, unbedded boulder gravel occurring as isolated erosional remnants. The materials are mainly from a granitic source but fragments of basalt, andesite, dacite, and metamorphic rocks are common. The unit is nearly everywhere above the water level in wells and is unsaturated. However, the attitude of this unit suggests that locally it may extend beneath the younger or older alluviiim in the valley, and possibly below the water table. In such places the material where saturated may yield small quantities of water to deep wells. 10 Old lacustrine deposits of late Pleistocene age are locally interbedded with the older alluvltun or the older fan deposits. These deposits are silt, clay, fresh-water limestone, lime- cemented gravel, and sand. In some localities, these deposits contain numerous fossils. The river alluvium of Recent age is composed mainly of fine >"• gravel and sand. Where 8at\irated it yields water freely to wells. '""* The river alluvium underlying the flood plain of the Mnjave River, where most of the wells are drilled to shallow depths, is the principal water-bearing unit in the area. However, beneath nwch of the area west of the river where the depth to water is greater and where the younger alluvium is absent and the younger fan de- posits are unsaturated, the wells yield water derived from the older alluvium. *"''■'" ••"•' ^'^''- - The younger alluvium of Recent age beneath the alluvial plains of Hinkley and Harper Valleys is composed mainly of fine -.3^ sand and gravel, inhere saturated these deposits yield water readily to wells. The younger fan deposits of Recent age are mostly poorly sorted boulders, arkosic gravel, sand, silt, and clay derived from nearby hills or mountains. The materials have been transported only a short distance and mainly represent raudflow or slope-wash debris. Near the hills and mountains the younger fan deposits are coarse grained, but they become finer with increasing distance from the areas of active erosion. These deposits are poorly sorted and poorly permeable, are usually above the water table, and proba- bly would not yield much water to wells. 11 Playa deposits of Recent age occur principally at the "base level of some minor drainage areas. They consist principally of silt and clay and minor amounts of sand, are of low permeability, and where saturated usually contain water having a moderate to very high dissolved-solids content. The river-channel deposits beneath the active channel of the Mojave River consist mainly of highly permeable sand v;hich permits large seepage losses to the ground-water body whenever runoff occurs. Unconsolidated coarse to fine dune sand occurs along the river near Hinkley Valley. The dunes are, in part at least, actively drifting; locally some small interdune playas are in- cluded in the area shown as dune sand on figure 2. In 1958 the water levels in wells ranged from near land sur- face beneath much of the land near the river to more than 200 feet below the surface of the higher parts of the alluvial fans and plains. The movement of ground water through the older alluvial deposits is complicated by several ground-water barriers, which are presumed to be major faults. Ground-water recharge to the area is from direct percolation of rain, (seepage loss) from the Mojave River, and subsurface ground-water flow from the west part of the Middle Mojave Valley area of Page, Moyle, and Butcher (1959). 12 The Ntojave River, vrhich is the principal stream in the area, carries runoff northeastward from the San Bernardino Mountains past the town of Victorville. On the north side of Victorville the stream flows on the surface only if excessive rainfall or melting snow causes the water taMe to rise above the stream channel. Direct percolation of rain to the water table generally is minor, but in some wet years it may be appreciable. The eastern part of the Middle Mojave Valley area includes about 390 square miles in nearly half of which consolidated rocks are exposed and in which virtually no wells are drilled. In the re- maining half of the area nearly 1,200 wells were canvassed during the Investigation. Of these, about 1,120 wells are described in table 1 and their locations are shown on figure 2; the others are destroyed or dry wells for which few or no data are available, and these are not included in table 1. 13 DESCRIPTION OF TABLES The tables in this report contain or refer to all knovm data, published and unpublished, for wells in the eastern part of the Middle Mojave Valley area. In table 1 all wells canvassed in the eastern part of the Middle rtojave Valley eirea for which data are available are listed in numerical order. In table 2 cross indexes are given for numbers previously assigned to wells by others and well numbers assigned by the Geo- logical Survey, In table 3 publications or reports which contain water-level measurements made in wells in the eastern part of the Middle Mojave Valley area are listed. In table k the wells are listed for which periodic water- level measurements are available. In table 5 all available vinpublished records of water levels in wells are listed. In table 6 drillers' logs of wells are listed. In table 7 chemical analyses of water from wells are listed. Ik WELL-NUMBERING SYSTEM The well-numbering system used in the eastern part of the Middle Mojave Valley area conforms to that used by the Geological Survey in California since I9U0. It has been adopted as official by the California Department of Water Resources and by the Calif- ornia Water Pollution Control Board for use throughout the State. Wells are assigned numbers according to their locations in the rectangular system for the subdivision of public land. For example, in the number 9/3-3^NU, which is assigned to the irriga- tion well of George S. Hall, the part of the number preceding the slash indicates the township (T. 9 N. ), the part between the slash and the hyphen is the range (R. 3 W. ), the number between the hyphen and the letter indicate the section (sec. 3U), and the letter indicates the UO-acre subdivision of the section as shown in the accompanying diagram. D C B 1 A E F I G 1 H M L K J N P Q R 15 Within the 1+0-acre tract the wells are numbered serially as indicated by the final digit. Thus, well 9/3-3UNU is the fourth well to be listed in the SW-^SW^ sec. '^k. Because the entire area lies in the northwest quadrant of the San Bernardino base and meridian lines, the foregoing abbreviations of township emd range numbers are sufficient. For some wells the letter following the section number is designated X in place of one of the 16 letters designating the i)-0-acre tract. This symbol indicates that the well has been located in the field and is accurately plotted with respect to its position on the map, but that the control for the public- land net is too poor to warrant assigning a more accurate location number. For certain well numbers a Z has been substituted for the letter designating the UO-acre tract; the Z indicates that the well is plotted from unverified location descriptions; the in- dicated sites of such wells were visited, but no evidence of a well could be found. 16 In this report, exceptions to the system of numbering vrells according to their position in the Uo-acre subdivisions of the section are found. These exceptions are the result of numbers having been assigned to wells prior to the publication of existing base maps. During this investigation, the locations of these mis- numbered wells were plotted more accurately. The originally as- signed numbers were retained in this report, however, for continuity with previously published reports and for ease of handling of records by automatic data processing units. Generally, these wells are fev in number and were seldom misplaced in the section by more than one adjoining UO-acre subdivision. 17 I REFERENCES Bader, J. S., Page, R. W., and Butcher, L.

The terms hardpan and adobe are also used to describe these same materials. Many drillers refer to water sand which means that the sand is permeable, but does not mean necessarily that the sand contains water. Many drillers refer to the blue clay , a term referring to the bluish-gray color of a particular clay or deposit rather than to a continuous stratigraphic unit or to a particular clay or deposit. In many instances a wet clay or deposit changes color when it is dried. The terms rotten granite and decomposed granite generally refer to a granite or bTotite gneiss that has been highly weathered. The term hillside is used to describe material that appears similar to the alluvial fan material on nearby slopes. The terras breaks and ribs refer to thin interbedded layers of alternating material. Quicksand is a term often applied by drillers to sand that caved or "heaved"' into the well during drilling. 8/1-29F1. Vern Cyr. Altitude about 2,870 ft.
