This digital data set delineates the boundary of the Death Valley region that was first evaluated by the U.S. Geological Survey (USGS) as a potential hydrogeologic environment for isolation of high-level radioactive waste in 1981. Identifying potential high-level waste isolation regions within the Basin and Range physiographic province continued through the 1980's and resulted in comprehensive geologic and hydrologic characterization of select areas. As part of these studies, Bedinger and others (1989) evaluated the Death Valley region, an area of about 80,200-square kilometers in southern Nevada and California, with respect to the geology at repository target depths, ground-water flow, potential transport of radionuclide material, mineral and energy resources, geomorphic processes, tectonic hazards, and the effects of climatic and geomorphic change on the ground-water system. The study by Bedinger and others (1989) served as one of the historical references used to support development of the transient ground-water model of the Death Valley regional ground-water flow system (DVRFS) completed in 2004 by the USGS (see "Larger Work Citation").

This digital data set is a historical definition of the extent (approximately 42,600 square-kilometers) and lateral boundary of the Death Valley regional ground-water flow system (modified from Harrill and others, 1988; and Harrill and Prudic, 1998). Harrill and others (1988) developed boundaries for the major ground-water flow systems in the Great Basin region of Nevada, Utah, and adjacent states using the boundaries of hydrographic areas. Harrill and Prudic (1998) refined the delineation of the Death Valley ground-water flow system by using a more accurate base map. The studies by Harrill and others (1988) and Harrill and Prudic (1998) served as historical references used to support development of the transient ground-water model of Death Valley regional ground-water flow system (DVRFS) completed in 2004 by the USGS (see "Larger Work Citation", Chapter A, pages 9-10, for details).
