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historical references used to support development of the transient ground-water model of Death Valley regional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).
This digital data set represents the historical delineation of the Death Valley regional ground-water flow system
modified from Harrill and others (1988) and Harrill and Prudic (1998) that was based primarily on hydrographic
areas. This data set is used to illustrate and compare historical definitions of the Death Valley regional ground-
water flow system published by the USGS (see "Larger Work Citation", figure A-2, p. 10).
The Death Valley regional aquifer system boundary is one of many spatial layers in a spatial database supporting
the USGS DVRFS project. This 5-year (1998-2004) project, completed in cooperation with DOE and other Federal,
State, and local agencies, developed this spatial database for a regional-scale, 3D hydrogeologic framework model
(HFM) and a ground-water flow model. The models are intended to address water-resource issues and the potential
movement of radioactive material from the Nevada Test Site or the proposed high-level nuclear waste repository at
Yucca Mountain, Nevada.
Data from two previous ground-water flow models of the greater Death Valley region (see "Larger Work Citation",
Chapter A, p. 7) were the foundation of the DVRFS geospatial database. These and other data were reexamined
through a series of regional-scale hydrologic investigations to provide updated and spatially consistent interpretations
for the DVRFS study. In some cases, new data were collected to augment the existing information. Data compiled
from the studies include natural ground-water discharge occurring through evapotranspiration and spring flow; ground-
water pumping for the period 1913-98; ground-water recharge simulated as net infiltration; ground-water inflow and
outflow at lateral model boundaries; hydraulic conductivity and its relation to depth and other rock properties; and the
estimation of water levels representative of prepumped and pumped conditions in the region. Digital elevation models,
geologic maps, borehole information, cross sections, and other 3D models were used to develop the HFM which
represents the geometry of 27 hydrogeologic units and structural features. The resulting geospatial database
supports characterization and conceptualization of the DVRFS, construction of 3D hydrogeologic framework and
ground-water flow models, and visualization of analysis and model results.

Spatial data sets supporting the Death Valley regional ground-water flow system (DVRFS) project were developed in cooperation with the U.S. Department of Energy's (DOE) National Nuclear Security Administration/Nevada Site Office (NNSA/NSO) Underground Test Area (UGTA) project of the Office of Environmental Management, the NNSA/NSO Hydrologic Resource Management Program (HRMP), the Office of Civilian Radioactive Waste Management's (OCRWM) Office of Repository Development (ORD), the NNSA/NSO Maintenance of Test Capability (MTC) program, and the National Park Service (NPS).

Attributes added by the GIS and the data set author were checked by inspection using a GIS. In addition, attributes were checked and evaluated as part of the review process associated with the publication of the source report.
Lines forming the polygon join at endpoints to completely enclose the area. Lines do not intersect, and no duplicate line features exist. All endpoints are represented by a single coordinate pair which indicates the beginning or end of a line.
The polygon feature in this data set was digitized from hard copy in Harrill and others (1988). The area defined by the polygon is the Death Valley flow system delineated by Harill and Prudic (1998). The data set is complete and is not anticipated to change.
Horizontal positional accuracy of line features in the data set was tested by visually comparing hard copy plots to the original source maps.

Figure 2 and Table 1 define the Death Valley flow system subregion.
The polygon feature in this data set, defined by Harrill and Prudic (1998), was identified on the paper-based copy of sheet 2 in Harrill and others (1988) and manually traced onto a stable base mylar. A drumbed scanner was then used to capture the digital data at a resolution of approximately 0.01 inches. A minimum of four control points corresponding to the latitude and longitude even degree locations on the plate were used to register the data to Universal Transverse Mercator (UTM) during digitization. The digital data set was checked by comparing plots to the source material and the coverage was attributed.
