VERTICAL DATUM AND WELL-NUMBERING SYSTEM

VERTICAL DATUM

Sea level: In this report, "sea level" refers to the National Geodetic Vertical Datum of 1929 (NGVD of 1929) a geodetic datum derived from a general adjustment of the first- order level nets of both the United States and Canada, formerly called Sea Level Datum of 1929.

Water Year: A water year is the 12-month period October 1 through September 30. The water year is designated by the calendar year in which it ends. Thus, the water year ending September 30, 1996, is called water year 1996.

Temperature in degrees Fahrenheit (°F) may be converted to degrees Celsius (°C) as follows:

DC = (°F-32)71.8

WELL-NUMBERING SYSTEM

Wells and springs are identified and numbered according to their location in the rectangular system for the subdivision of public lands. Identification consists of the township number, north or south; the range number, east or west; and the section number. Each section is divided into sixteen 40-acre tracts lettered consecutively (except I and O), beginning with A in the northeast corner of the section and progressing in a sinusoidal manner to R in the southeast corner. Within the 40-acre tract, wells are sequentially numbered in the order they are inventoried. The final letter refers to the base line and meridian. In California, there are three base lines and meridians; Humboldt (H), Mount Diablo (M), and San Bernardino (S). All wells in the study are referenced to the San Bernardino base line and meridian (S). Well numbers consist of 15 characters and follow the format 004N004W36Q001S. In this report, well numbers are abbreviated and written 4N/4W-36Q1. The following diagram shows how the number for well 4N/4W-36Q1 is derived:

Regional Water Table (1996) and Water-Level Changes in the Mojave River, the Morongo, and the Fort Irwin Ground-Water Basins, San Bernardino County, California

By Gregory O. Mendez and Alien H. Christensen

Abstract

The Mojave River, the Morongo, and the Fort Irwin ground-water basins lie in the southwestern part of the Mojave Desert Region of southern California. These basins supply ground water to local water districts, military bases, and private wells. The rapid growth in population in these basins, which is due, in part, to their proximity to Los Angeles, has increased the demand for water and, therefore, the need to understand the Mojave ground-water systems.

Ground-water conditions for the Mojave River, the Morongo, and the Fort Irwin ground- water basins for 1996 and areas with significant changes in water levels are identified in this report. Water-level data were compiled for 632 wells in the study area during January-September 1996 to define the water-table surface and direction of ground-water movement. These data were used to construct the water-table map included in this report. Also shown on the map are 31 hydrographs that show long-term water-level changes in the study area. Short-term water-level changes were determined and a water-level change map was made by comparing 1996 ground-water conditions to 1990-94 conditions in the Mojave ground- water basin and to 1994 conditions in the Morongo and the Fort Irwin ground-water basins.

In general, ground-water levels and the direction of ground-water movement in the regional aquifer have not changed significantly

since previously published maps (1995). However, the short-term water level did change at specific locations in all three ground-water basins. Water levels in the Mojave River ground-water basin had a maximum rise during the period 1992- 96 of 52 feet and a maximum decline of 28. Water levels in the Morongo ground-water basin had a maximum rise of 66 feet and a maximum decline of 57 feet. The Fort Irwin ground-water basins, however, had relatively little change in water level with a maximum rise of 6 feet and a maximum decline of 8 feet. Hydrographs in the regional aquifer system indicate a decline or, in some areas, no change in the water table during the period of record. Water levels in the shallow alluvial aquifer, generally within 1 mile of the Mojave River, fluctuate in response to streamflow. Ground-water levels rise during wet periods, when floodflows in the Mojave River recharge the shallow alluvial aquifer.

INTRODUCTION

The Mojave River, the Morongo, and the Fort Irwin ground-water basins lie in the southwestern part of the Mojave Desert region of southern California (fig. 1). Surface water, including the Mojave River, is intermittent in most of the region; there is no reliable supply of surface water. Local water districts, municipalities, military bases, and private well owners rely almost entirely on local ground water for supply.

Localized heavy ground-water withdrawal has resulted in overdraft in parts of the basins. To understand and manage the ground-water resources, ground-water conditions periodically need to be documented.

This study was done by the U.S. Geological Survey (USGS), in cooperation with the Mojave Water Agency, the U.S. Marine Corps Air/Ground Combat Center at Twentynine Palms (USMCAGCC), and the Fort Irwin National Training Center (NTC).

Purpose and Scope

The purposes of this study were to document the ground-water conditions for the Mojave River, the Morongo, and the Fort Irwin ground-water basins in 1996 and to identify areas that have had significant

short- or long-term water-level change. In 1996, water- levels were measured in 632 wells (table 1, at back of report) and the data were used to construct a water- table map (pi. 1, in pocket). Historical water-level data were used to construct hydrographs (pi. 1) that show long-term water-level changes in selected wells in the study area. Short-term water-level changes in the Mojave River, the Morongo, and the Fort Irwin ground-water basins were determined by comparing 1996 and 1990-94 data.

DESCRIPTION OF THE STUDY AREA

The climate of the Mojave Desert region of southern California is characterized by low precipitation and humidity and temperatures that range from above 100°F in the summer to below 32°F in the winter. Average annual precipitation in the study area ranges from 4 to 6 in., although it can be greater than 20 in. in the San Bernardino and the San Gabriel Mountain Ranges to the south (Rantz, 1969). Recharge to the ground-water system from direct infiltration (areal recharge) of precipitation is minimal.

The area of the Mojave River, the Morongo, and the Fort Irwin ground-water basins is about 2,430 mi2 (fig. 1). Although these basins are largely undeveloped, desert communities are expanding rapidly in areas within commuting distance of the Los Angeles metropolitan area. The military bases the NTC north of Barstow and the USMCAGCC near Twentynine Palms cover much of the study area (pi. 1). Agricultural development primarily is concentrated along the Mojave River and around the communities of Newberry Springs and Lucerne Valley.

The Mojave River ground-water basin has an area of about 1,400 mi2 and extends from the San Bernardino and the San Gabriel Mountains on the south to Afton Canyon on the northeast (pi. 1). The basin is bounded by Antelope Valley to the west and shares its southeastern boundary with the Morongo ground-water basin near the town of Lucerne Valley. The Mojave River ground-water basin consists of several alluvial-filled valleys and ground-water basins that are hydraulically connected. The Mojave River ground-water basin, which is an adjudicated ground- water basin, consists of five subareas: Alto, Baja, Centra, Este, and Oeste (fig. 2 on pi. 1). The Alto subarea has a component called the Alto Transition area, which is the area between the Lower Narrows and the Centra subarea.

The Mojave River is the principal source of ground-water recharge to the Mojave River ground- water basin. When surface water is present, the river flows northward from the San Bernardino Mountains through Victorville, then eastward through Barstow, and exits the Mojave ground-water basin at Afton Canyon almost 100 mi from its headwaters.

The Morongo ground-water basin has an area of about 1,000 mi2 and is bounded by the San Bernardino Mountains to the southwest, the Granite and the Ord Mountains to the northwest, the Bullion Mountains to the northeast, and the Little San Bernardino and the Pinto Mountains to the south (pi. 1). The Morongo ground-water basin is divided into 17 ground-water subbasins: Copper Mountain, Deadman, Emerson, Fry, Giant Rock, Johnson, Joshua Tree, Lucerne, Mainside, Means, Mesquite, Pipes, Reche, Surprise Spring, Twentynine Palms, Upper Johnson, and Warren (fig. 2 on pi. 1). The Morongo ground-water basin has no significant source for ground-water recharge other than from small, intermittent washes.

The Irwin, the Langford, and the Bicycle ground-water basins are referred to in this report as the Fort Irwin ground-water basins (pi. 1). These three basins lie within and provide the water supply to the NTC. The Fort Irwin ground-water basins have a total area of about 30 mi2. Similar to the Morongo ground- water basin, the Fort Irwin ground-water basins have no perennial surface-water and, therefore, no significant source of natural ground-water recharge.

GEOHYDROLOGY

Non-water-bearing igneous and metamorphic rocks underlie the ground-water basins and form the surrounding mountains and hills in the study area. These rocks contain virtually no water, except in joints or fractures. In some places within the ground-water basins and along their boundaries, these non-water­ bearing rocks are not exposed, but their presence above the altitude of the water table forms a barrier to ground- water movement.

In the Mojave River ground-water basin, the water-bearing deposits are unconsolidated and partly consolidated continental deposits of Quaternary and Tertiary age. These deposits form two major aquifers: a shallow alluvial aquifer and an underlying regional aquifer. The shallow alluvial aquifer overlies the regional aquifer along the Mojave River and consists of permeable river deposits as thick as 200 ft that are

Geohydrology 3

generally within 1 mi of the river. The shallow alluvial aquifer is the most productive aquifer in the ground- water basin and yields much of the ground-water supply. The regional aquifer consists of unconsolidated older alluvium, fan deposits, and partly consolidated to consolidated sedimentary deposits as thick as 1,000 ft. These deposits are generally fine grained and their permeability declines with depth.

Continental deposits of Quaternary and Tertiary age fill the Morongo ground-water basin to a maximum depth of 10,000 ft near the eastern edge of the basin north of Deadman Lake (Moyle, 1984). In general, the continental deposits are unconsolidated at land surface and become partly consolidated with depth. Most wells in the ground-water basin yield water from the unconsolidated deposits.

The Fort Irwin ground-water basins (modified from Wilson F. So and Associates, 1989) are filled with unconsolidated alluvial deposits from Quaternary to Tertiary age. The alluvial deposits are as thick as 950 ft in the northern part of the Irwin ground-water basin (Densmore and Londquist, in press). Preliminary seismic studies of the Bicycle and the Langford ground-water basins, which are two of the Fort Irwin ground-water basins, indicate that the alluvial deposits are as thick as 1,000 ft (David L. Berger, U.S. Geological Survey, written commun., 1996).

The Mojave Desert region of southern California is dominated by northwest- to southeast-trending right- lateral faults, which indicate some vertical movement. Large differences in water levels across some of these faults indicate that they are impediments to ground- water movement. The fault coverage shown on plate 1 was modified from Bortugno (1986) and Cox and Wilshire (1994). A fault coverage was not available north of latitude 35°N.

GROUND-WATER LEVELS AND MOVEMENT

Water-level data were collected from 632 wells (table 1) during January-September 1996 to define the water-table surface and the direction of ground-water movement in the study area (pi. 1). The water table is best defined as the surface on which the fluid pressure in the pores of a porous medium is exactly atmospheric. The location of this surface is revealed by the level at which water stands in a shallow well open along its length and penetrating the surficial deposits just deep enough to encounter standing water in the

bottom (Freeze and Cherry, 1979). Most water levels were measured by the USGS with calibrated steel or electric tapes. Some water levels were reported by local water agencies (table 1). Water-table altitudes were calculated by subtracting the measured depth to water from the land-surface datum (determined from a leveling survey or estimated from topographic maps).

The USGS and other agencies have completed multiple-well monitoring sites (nested wells) within the study area for the collection of depth-dependent data (table 1). The water-table map (pi. 1) presents data collected from the shallowest well at a multiple-well monitoring site, except if the well is perforated in a perched aquifer. One area where perched water is well documented (2N/9E-29M3, -32J1, and -32R3, table 1) is in the Mainside subbasin under Mesquite Dry Lake (Morongo ground-water basin) and is about 140 ft above the regional aquifer (2N/9E-29Q1 and 29R1, table 1).

Ground water flows from areas of higher to areas of lower water-level altitude and perpendicular to lines of equal water-table altitude (contours) presented on the water-table map (pi. 1). In areas where water-table data were unavailable for 1996, the general shape of the contour was defined on the basis of previous water- table maps by Stamos and Predmore (1995) and Trayler and Koczot (1995). An inset map of southern Warren subbasin, within the Morongo ground-water basin, was made to enhance the detail of water-level contours in the Yucca Valley area (inset A, pi. 1).

Inspection of water-table contours in the vicinity of faults indicates that some faults in the study area are barriers to ground-water flow (pi. 1). The barrier effect of the faults is probably caused by compaction and deformation of water-bearing deposits immediately adjacent to the faults and by cementation of the fault zone by mineral deposits from ground water (Londquist and Martin, 1991). For example, there is approximately a 60-ft drop in the water level across the Calico-Newberry Fault, which crosses the Mojave River about 10 mi east of Barstow in the Mojave River ground-water basin. Similarly, there is a change in the water level of more than 300 ft across the Surprise Spring Fault near the extinct Surprise Spring about 10 mi east of Landers in the Morongo ground-water basin. The effect of faults on ground-water flow is emphasized by the past and current existence of springs at fault boundaries (Mesquite Spring, Old Woman Springs, Rabbit Springs, and Surprise Spring), which

indicates that ground water is, or has been, diverted to the surface at these locations.

WATER-LEVEL CHANGE

Historical water-level data were used in conjunction with data collected during this study to determine both long-term and short-term water-level changes in the study area. Long-term water-level changes were determined by constructing water-level hydrographs of wells in different parts of the study area (pi. 1) and short-term water-level changes (fig. 2 on pi. 1) were determined by comparing 1996 ground-water levels with previously published water-level measurements collected in 1990-94 (Stamos and Predmore, 1995) for the Mojave River ground-water basin and 1994 (Trayler and Koczot, 1995) for the Morongo and the Fort Irwin ground-water basins (table 1; fig. 2 on pi. 1).

LONG-TERM WATER-LEVEL CHANGES

Thirty-one hydrographs show (pi. 1) long-term water-level changes in the study area. Selected hydrographs include data from more than one well in order to show a longer period of record. These long- term hydrographs indicate a general decline in water levels in wells near areas of heavy ground-water withdrawal in the regional aquifer.

In the Alto subarea of the Mojave ground-water basin, water levels have declined as much as 60 ft since the 1940's (4N/3W-1M1 and 5N/5W-22E1, -22E2). This decline is a reflection of ground-water withdrawal for the cities of Adelanto, Apple Valley, Hesperia, and Victorville. In the Centre subarea, water levels west of Harper Lake (11N/4W-29R1) have declined about 90 ft since 1954; water levels east of Harper Lake (11N/3W- 28R1, -28R2) have declined about 30 ft since 1950, probably because of agricultural pumpage; and water levels east of Iron Mountain and south of the Mojave River (combined hydrograph 9N/2W-19B1 and 9N/ 3W-13R1) have declined about 30 ft since 1932. Water levels have remained relatively constant in the southeastern part of the subarea (9N/1W-27D1), where ground-water withdrawal from the regional aquifer is minimal. In the eastern part of the Baja subarea near Newberry Springs, the water table has declined as much as 75 ft since 1930 (9N/3E-34D1, -34N1); this

decline also reflects the effects of ground-water withdrawal for agriculture.

The hydrographs of wells in the shallow alluvial aquifer in the Alto and the Centro subareas, and to a lesser degree in the Baja subarea, show alternating periods of declining and rising water levels (4N/4W- 1D2; 5N/4W-11P1, -11P3; 8N/4W-12Q1; 8N/4W- 31R1; 9N/3E-3D1, -3D2; 10N/2W-32B1, and-33R16). This cyclic pattern is related to the amount of flow in the Mojave River. During dry periods, when most of the Mojave River is dry and recharge from the river to the shallow alluvial aquifer is minimal, ground-water levels decline in response to natural discharge (evapotranspiration and ground-water underflow to other subbasins) and ground-water withdrawal. Ground-water levels rise during wet periods, when floodflows in the Mojave River recharge the shallow alluvial aquifer.

In the Alto and the Centro subareas of the Mojave ground-water basin, long-term hydrographs indicate a general declining trend for wells in the shallow alluvial aquifer. The exception to this declining trend is shown by the hydrographs for wells (5N/4W-11P1, -11P3; 7N/4W-30C1), which have remained relatively constant. These wells are in the vicinity of the Narrows near Victorville where the Mojave River flows perennially. However, long-term hydrographs for wells in the Baja subarea indicate water-level declines of 50 ft or more (9N/1E-10L1; 9N/ 3E-3D1, -3D2 and 9N/3E-34D1, -34N1). Lines (1996) estimated that the shallow alluvial aquifer in the Alto and the Centro subareas receives some recharge from the Mojave River each year, whereas the aquifer in the Baja subarea receives recharge only during periods of high flow. The water-level declines in the Baja subarea are the result of natural discharge and agricultural pumpage.

In the Morongo ground-water basin, hydrographs indicate that water-levels have remained relatively constant in the Copper Mountain, the Deadman, the Johnson, and the Mesquite subbasins (1N/7E-23A1; 3N/7E-36G1, 3N/8E-29C1; 4N/3E- 23G1; 1N/8E-12G1 and 1N/9E-33H2, respectively) where the population is small and the pumpage is minimal. Available data were insufficient to determine long-term water-table fluctuations in the Emerson, the Fry, the Pipes, or the Upper Johnson subbasins. Water- tables have declined in the Lucerne, the Reche, the Surprise Spring, the Twentynine Palms, and the Warren subbasins. In the Lucerne subbasin, the water levels

Long-Term Water-Level Changes 5

have declined about 100 ft in wells 5N/1W-25G1 and 5N/1E-17D1 since the early 1950's. In the Reche subbasin, The water level has declined 45 ft in well 2N/ 6E-18B1 since 1963. In the Twentynine Palms subbasin, the water level has declined 32 ft in well IS/ 9E-3D1 since 1940. In the Surprise Spring subbasin, the water levels have remained relatively constant in well 3N/7E-31E1, but it has declined 115 ft in well 2N/ 7E-2C1 since 1952 as a result of ground-water withdrawal for USMCAGCC. In the Warren subbasin near Yucca Valley, water levels have declined 309 ft in wells 1N/5E-36K1 AND -36K2 (combined hydrograph, pi. 1), since 1947. In the western part of the Warren subbasin, the water table has declined about 178 ft in well 1N/5E-34N1 since the late 1950's. These large declines probably are a result of pumpage for the Yucca Valley area.

In the Fort Irwin ground-water basins, data were available to construct long-term hydrographs for wells 14N/3E-14H1 and -32J1 in the Bicycle and the Irwin ground-water basins, respectively. These long-term hydrographs indicate that ground-water withdrawals to supply the NTC have resulted in water-table declines of about 70 ft since the late 1960's in the northern part of the Bicycle ground-water basin and about 30 ft since 1943 in the central part of the Irwin ground-water basin.

SHORT-TERM WATER-LEVEL CHANGES

A water-table change map (fig. 2 on pi. 1) was made by comparing 1996 ground-water levels with water levels reported by Stamos and Predmore (1995) for the Mojave River ground-water basin and by Trayler and Koczot (1995) for the Morongo ground- water basin. Short-term water-level changes were determined by comparing 1996 ground-water levels with previously published water-level measurements collected during 1990-94 for the Mojave River ground-water basin and during 1994 for the Morongo ground-water basin (Trayler and Koczot, 1995). Twenty wells measured in 1994 in the Fort Irwin ground-water basins were compared with 1996 water- level data.

In the Mojave River ground-water basin, the maximum water table rise was 52 ft and the maximum decline was 28 ft during the period 1992-96. The water level rose in at least one well during this period in all subareas. The most significant rises were in the Alto and the Centre subareas in the shallow alluvial aquifer,

owing to ground-water recharge from floodflows in the Mojave River. Near the headwaters of the Mojave River in the Alto subarea, the water level rose about 22 ft in well 4N/3W-31L9. In the Transition area (within the Alto subarea), two wells had a rise in water level, the largest of which was about 30 ft in well 7N/4W- 6N1. Where the Mojave River enters the Centre subarea, the water level rose about 13 ft in well 8N/4W- 10Q1. Near Barstow, the water level rose about 45 ft in well 9N/3W-1R7 and 52 ft in well 9N/2W-1A2. East of Barstow, the water level rose about 28 ft in well 9N/ 1W-4J8. In the Baja subarea, east of the Camp Rock- Harper Lake Fault zone, formerly called the Waterman Fault, the water table indicated no significant change from previous measurements. In the Este subarea, the water level in well 4N/2W-12N2 rose about 12 ft. In the Oeste subarea, the water level in well 5N/7W-17D1 rose about 7 ft.

The water-table change map also indicates the Mojave River ground-water basin had some areas where the water table has declined. In the Alto, the Centre, the Este, and the Oeste subareas, 11 wells indicated a decline in the water table. In the Baja subarea north of the Mojave River, 13 wells indicated a decline. The quantity and frequency of flow in the Mojave River declines rapidly when it reaches the Baja subarea (Lines, 1996); therefore, this subarea does not receive much ground-water recharge from stormflo ws.

In the Morongo ground-water basin, the maximum rise in the water table was 66 ft and the maximum decline was 57 ft. There was an rise in water levels in only 6 of the 17 ground-water subbasins. Of the wells measured in the Copper Mountain, the Deadman, the Pipes, and the Surprise Spring subbasins, only one well in each subbasin had a rise in water level. In the Lucerne subbasin, five wells had a rise in water levels with the largest rise of about 14 ft in well 5N/1W-36R1. The largest water table rise and decline in the Morongo ground-water basin was in the Warren subbasin. The water-level rise of nearly 66 ft in well 1N/5E-36K3 probably resulted from a decrease in pumpage in the subbasin. The decline of nearly 57 ft in well 1N/6E-31C1 probably resulted from inadequate time for recovery from pumping before the water-level measurement was made. The water-table change map also indicates that the water table declined by more than 5 ft in wells near the towns of Landers, Twentynine Palms, and Yucca Valley, which are supplied by municipal and domestic withdrawals of ground water.

6 Regional Water Table (1996), Water-Level Changes Mojave River, Morongo, Ft. Irwin Ground-Water Basins, San Bernardino Co.

The water table in the Fort Irwin ground-water basins has remained relatively unchanged, with a maximum rise in the water table of 6 ft and the maximum decline of 8 ft. Of the 11 wells measured in the Irwin ground-water basin, only well 14N/3E-32P6 indicated a significant rise in the water table (about 6 ft). In the Bicycle ground-water basin, well 14N/3E- 24H1 had a decline in the water level of about 6 ft and well 14N/4E-18N2 had a decline of about 8 ft. In the Langford ground-water basin, none of the four wells measured had water level fluctuations of more than 5 ft.
