“…The central part of the Amargosa Desert is a north-trending trough, which is much deeper than the east and west arms of the Amargosa Desert basin-complex (Blakely and others, 1999). The basin fill in the northern part of this trough resembles that of the western arm of the Amargosa Desert (Oatfield and Czarnecki, 1989;Carr and others, 1995), whereas that of the southern part of the trough is more similar to the central Death Valley rhombochasm, but with a larger proportion of interbedded sandstones, which probably have moderate to low permeability (Naff, 1973). In summary, the basin fill includes a widespread high quality alluvial aquifer in the east and west arms of the Amargosa Desert and in the northern part of the central trough.…”

“…In summary, the basin fill includes a widespread high quality alluvial aquifer in the east and west arms of the Amargosa Desert and in the northern part of the central trough. Permeability of the basin-fill decreases southward within the southern part of the Amargosa trough (Oatfield and Czarnecki, 1989;Naff, 1973), based on the southward increasing abundance of altered nonwelded tuffs.…”

“…A principal difficulty in the initial compilation and stratigraphic analyses of borehole data from the Amargosa Desert involved integrating subsurface lithologic data known to be of high quality, such as those data from the Nye County Early Warning Drilling Program (EWDP) boreholes to the south of Yucca Mountain and the Felderhoff boreholes (Carr and others, 1995) with information contained in driller's logs that are source of data for many of the holes in the Amargosa Farms area (Oatfield and Czarnecki, 1989) Tertiary volcanic rocks, undif.…”

Existing hydrologic models of the Death Valley region typically have defined the Cenozoic basins as those areas that are covered by recent surficial deposits, and have treated the basin-fill deposits that are concealed under alluvium as a single unit with uniform hydrologic properties throughout the region, and with depth. Although this latter generalization was known to be flawed, it evidently was made because available geologic syntheses did not provide the basis for a more detailed characterization. As an initial attempt to address this problem, this report presents a compilation and synthesis of existing and new surface and subsurface data on the lithologic variations between and within the Cenozoic basin fills of this region. The most permeable lithologies in the Cenozoic basin fills are freshwater limestones, unaltered densely welded tuffs, and littleconsolidated coarse alluvium. The least permeable lithologies are playa claystones, altered nonwelded tuffs, and tuffaceous and clay-matrix sediments of several types. In all but the youngest of the basin fills, permeability probably decreases strongly with depth owing to a typically increasing abundance of volcanic ash or clay in the matrices of the clastic sediments with increasing age (and therefore with increasing depth in general), and to increasing consolidation and alteration (both hydrothermal and diagenetic) with increasing depth and age. This report concludes with a categorization of the Cenozoic basins of the Death Valley region according to the predominant lithologies in the different basin fills and presents qualitative constraints on the hydrologic properties of these major lithologic categories.

Average‐annual volumes of runoff, evapotranspiration, channel loss, upland (interchannel) recharge, and total recharge were estimated for watersheds of 53 channel sites in the Amargosa River basin above Shoshone, California. Estimates were based on a water‐balance approach combining field techniques for determining streamflow with distributed‐parameter simulation models to calculate transmission losses of ephemeral streamflow and upland recharge resulting from high‐magnitude, low‐frequency precipitation events. Application of the water‐balance models to the Amargosa River basin, Nevada and California, including part of the Nevada Test Site, suggests that about 20.5 million cubic meters of water recharges the ground‐water reservoir above Shoshone annually. About 1.6 percent of precipitation becomes recharge basinwide. About 90 percent of the recharge is by transmission loss in channels, and the remainder occurs when infrequent storms yield sufficient precipitation that soil water percolates beyond the rooting zone and reaches the zone of saturation from interchannel areas. Highest rates of recharge are in headwaters of the Amargosa River and Fortymile Wash; the least recharge occurs in areas of relatively low precipitation in the lowermost Amargosa River watershed.
