WELL-NUMBERING SYSTEM
W
ells 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 area are referenced to the San Bernardino base line and meridian (S) Well numbers consist of up to 15 characters and follow the format 004N003W1M001S. In this report, well numbers are abbreviated and written 4N/3W-1M1. Wells in the same township and range are referred to only by their section designation, 1M1. The following diagram shows how the number for well 4N/3W-1M1 is derived.

Regional Water Table (2000) and Ground-Water-Level Changes in the Mojave River and the Morongo Ground-Water Basins, Southwestern Mojave Desert, California
By Gregory A. Smith
ABSTRACT
The Mojave River and Morongo ground-water basins are in the southwestern part of the Mojave Desert in southern California. Ground water from these basins supplies a major part of the water requirements for the region. The continuous population growth in this area has resulted in ever-increasing demands on local ground-water resources. The collection and interpretation of ground-water data helps local water districts, military bases, and private citizens gain a better understanding of the ground-water systems, and consequently, water availability.
During 2000, the U. S. Geological Survey and other agencies made approximately 2,500 water-level measurements in the Mojave River and the Morongo ground-water basins. These data document recent conditions and, when compared with previous data, changes in ground-water levels. A water-level contour map was drawn using data from about 500 wells, providing coverage for most of the basins. Twenty-nine hydrographs show long-term (up to 70 years) water-level conditions throughout the basins, and 13 short-term (1996 to 2000) hydrographs show the effects of recharge and discharge along the Mojave River. In addition, a water-level-change map was compiled to compare 1998 and 2000 water-levels throughout the basins.
In the Mojave River ground-water basins, water-level data showed little change from 1998 to 2000, with the exception of areas along the Mojave River. Water levels along the Mojave River were typically in decline or unchanged, with exceptions near the Hodge and the Lenwood outlet, where water levels rose in response to artificial recharge. The Morongo ground-water basin had virtually no change in water levels from 1998 to 2000, with the exception of Yucca Valley, where artificial recharge and ground-water withdrawal continues.
INTRODUCTION
The Mojave River and the Morongo ground-water basins are in the southwestern part of the Mojave Desert in southern California, approximately 80 and 40 mi northeast, respectively, of Los Angeles (fig. 1). Surface water in these basins is minimal and is normally limited to ephemeral flow during winter and spring storms. There is however, continuous flow from springs in some areas of the Morongo ground-water basin, and in parts of the Mojave River ground-water basin where the water table intersects the river channel. The lack of significant surface-water resources has resulted in the use of ground water as the primary source for private, agricultural, and municipal supply. Owing to increasing urbanization, demands on local water supplies have created overdraft conditions in some areas of the desert basins. Periodic monitoring of ground-water levels aids in the management of the Mojave River and the Morongo ground-water basins.

2 Regional Water Table (2000) and Ground-Water-Level Changes, Mojave River and Morongo Basins, Southwestern Mojave Desert, California
-
In a continuing effort to monitor ground-water conditions in the Mojave River and the Morongo ground-water basins, the U.S. Geological Survey (USGS), in cooperation with the Mojave Water Agency, constructed a water-table map describing present (2000) ground-water conditions. Water-level data were collected from approximately 500 wells to construct the map, which shows the altitude of the water table and general direction of ground-water movement. Historical water-level data were used to create 29 hydrographs and to show long-term water-level changes, for as much as 70 years, in selected wells (pl. 1). An additional 13 short-term hydrographs (1996–2000) for wells along the Mojave River were constructed to show the water-level changes during seasonal recharge and discharge (pl. 1). Short-term water-level changes were determined by comparing 1998 and 2000 water levels. These data were used to create a water-level-change map (fig. 2). This report is a continuation of a series of previously published USGS reports and maps by Stamos and Predmore (1995), Trayler and Koczot (1995), Mendez and Christensen (1997), and Smith and Pimentel (2000).

Description of Study Area
The Mojave River and the Morongo ground-water basins together encompass about 2,400 mi2. The climate of these basins is typical of the Mojave Desert
region of southern California. Annual temperatures average 64°F and range from 3°F in the winter to above 116°F in the summer (Densmore and Londquist, 1997). Most areas of the basin floor receive 4 to 6 in./yr of precipitation, although annual precipitation can be greater than 40 in. in the southern and eastern San Bernardino and the San Gabriel Mountains (Lines, 1996). Recharge to the ground-water system from direct infiltration of precipitation is minimal.
The Mojave River ground-water basin is approximately 1,400 mi2 and extends from the San Bernardino and the San Gabriel Mountains in the south to near the Gravel Hills and the Fort Irwin National Training Center in the north (pl. 1, fig. 1). The ground-water basin is bordered on the west by Antelope Valley and shares its southeastern boundary with the Morongo ground-water basin. For water-management purposes, the Mojave River ground-water basin has been divided into five subareas; Alto (including a transition zone), Baja, Centro, Este, and Oeste (fig. 2).
The primary source of ground-water recharge in the Mojave River ground-water basin is intermittent streamflow in the Mojave River. Since July 1994, the basin has received additional recharge due to the release of imported water to the Mojave River at the Rock Springs Outlet (near well 4N/3W-31L9) southeast of Hesperia (Mojave Water Agency, 1996). Since 1998, recharge water also has been released at the Lenwood Outlet (near well 9N/3W-1R7) and at the Hodge Outlet (near well 9N/3W-22J4)(pl. 1).
The Morongo ground-water basin is about 1,000 mi2 and is surrounded by the Ord and Granite Mountains to the north, the Bullion Mountains to the east, the San Bernardino Mountains to the southwest, and (not shown on pl. 1) the Pinto and Little San Bernardino Mountains to the south. The Morongo ground-water basin is separated into 17 subbasins; Copper Mountain, Deadman, Emerson, Fry, Giant Rock, Johnson, Joshua Tree, Lucerne, Mainside, Means, Mesquite, Pipes, Reche, Suprise Spring, Twentynine Palms, Upper Johnson, and Warren (fig. 2).
The Morongo ground-water basin is recharged by infiltration from flow in ephemeral stream channels and from artificial-recharge ponds. In 1995, the Mojave Water Agency installed the High Desert recharge ponds at Yucca Valley (near well 1N/5E-36M6) in the Warren subbasin (pl. 1).

GEOHYDROLOGY
The boundaries of the Mojave River and the Morongo ground-water basins are generally defined by the contact between water-bearing unconsolidated deposits and surrounding and underlying non-water-bearing consolidated igneous and metamorphic rocks. For a more comprehensive description of the geohydrology of the ground-water basins refer to Stamos and others (2001), Smith and Pimentel (2000), and Mendez and Christensen (1997).
Perched ground water has been identified in four areas of the Mojave River and the Morongo ground-water basins. Perched ground water is unconfined ground water separated from an underlying body of ground water by an unsaturated zone (Lohman, 1972). The approximate areas of perched ground water are near El Mirage Lake (dry), Adelanto (Montgomery Watson, 1998), Lucerne Valley (Jill Densmore, U.S. Geological Survey, written commun., 1999) and Mesquite Lake (dry) (Mendez and Christensen, 1997) (pl. 1 and fig. 3). Scant data were available for the Adelanto area; hence, the extent of the perched ground water is not clearly known and is based on the Montgomery Watson (1998) report.
GROUND-WATER LEVELS AND FLOW
Water-level data were collected in the spring of 2000 from 498 wells (table 1) in the Mojave River and the Morongo ground-water basins to determine the altitude of the water table and the direction of ground-water flow (pl. 1). The water table is the surface of a ground-water body at which the pressure is atmospheric. The water table is defined by the levels at which water stands in wells that just penetrate the water body (Lohman, 1972). The water-level measurements used for plate 1 are from wells with various perforated intervals in the saturated zone (water body). Although these wells may perforate different zones, the measured water levels accurately represent the water-table altitude and can be used with sufficient
confidence to indicate the general direction of ground-water flow; ground water flows from areas of higher to areas of lower hydraulic head, (downgradient) and perpendicular to the water-level contours (pl. 1). Where 2000 water-level data were not available, contours were based largely on 1998 water-level conditions reported by Smith and Pimentel (2000).
As part of ground-water observation network, the USGS, in cooperation with local water agencies, water districts, the military, and private landowners, has constructed many multiple-well monitoring sites (table 1). These sites consist of a cluster of two or more observation wells completed at different depths within a single borehole, each typically screened across a 20-foot interval. Data from the shallowest well of a multiple-well site were used for the regional water-table map. In areas of a perched water table, both the perched and regional water levels are shown on the water-level map (pl. 1and fig. 3).
The 2000 water levels were measured using a steel tape or a calibrated electric tape; when neither of these methods was possible, an airline was used. Water-level data collected by other agencies were validated and deemed to adhere to USGS guidelines (noted as “reported” in table 1). The water-level altitude was determined by subtracting the water-level measurement (depth to water, in feet below land surface) from the established land-surface altitude above sea level.
WATER-LEVEL CHANGES
In most areas of the Mojave River and Morongo ground-water basins, water levels remained relatively unchanged from 1998 to 2000 (fig. 2); however, there were some significant changes along the Mojave River in the Alto and Baja subareas and in the Centro subarea near Hodge and Lenwood. In the Morongo ground-water basin, water levels rose significantly in the Lucerne and Warren subbasin. To illustrate water-level changes for periods greater than 2 years, 42 hydrographs were created for the basins (pl. 1).

Water-Level Changes 7
-
Historical water-level data were used in conjunction with data collected during this study to determine both long-term (1930–2000) and short-term (1996–2000) water-level changes in the Mojave River and the Morongo ground-water basins. Long-term water-level changes are depicted by 29 water-level hydrographs (pl. 1) that include data collected from the early 1930s. Some hydrographs combine data from more than one well in order to show water-level changes over a greater period in a given area. Thirteen short-term hydrographs were constructed from data collected between 1996 and 2000 along the Mojave River (pl. 1). These short-term hydrographs show the effects of seasonal recharge and discharge along the river. Recharge along the Mojave River is primarily from infiltration of stormflows, usually during January through March and artificially at the Rock Springs, Hodge, and Lenwood outlets (pl. 1).
In the Mojave River ground-water basin, a comparison of ground-water levels measured in the spring of 1998 and the spring of 2000 (fig. 2) indicates that changes in the regional aquifer system generally were less than or equal to 5 ft. Water levels measured in
wells along the Mojave River showed the greatest change. In the Alto subarea, water levels declined as much as 37 ft. Farther downstream in the eastern Centro and the Baja subareas, water levels declined as much as 35 ft. Water levels in the Alto Transition Zone showed little change. However, water levels in the Centro subarea rose as much as 22 ft near the artificial-recharge sites of the Hodge Outlet (near well 9N/3W-22J4) and the Lenwood Outlet (near well 9N/3W-1R7) (pl. 1).
In the Morongo ground-water basin, a comparison of ground-water levels measured in the spring of 1998 and the spring of 2000 (fig. 2) indicates that, in most wells, water levels changed 5 ft or less. However, wells in the Warren and Lucerne subbasins showed greater water-level changes. In the Warren subbasin, continuing artificial ground-water recharge has resulted in water-level rises as great as 49 ft (well 1N/5E-36M6); however, water levels in other parts of this subbasin declined as much as 69 ft (well 1N/5E-36L1) (fig.4). In the Lucerne subbasin, water levels rose as much as 24 ft and declined as much as 7 ft.
