This digital data set defines the lateral boundary of the area simulated by the steady-state ground-water flow model
of the Death Valley regional ground-water flow system (DVRFS) by D'Agnese and others (2002). The DVRFS flow
model was developed by the U.S. Geological Survey (USGS) for the U.S. Department of Energy (DOE) to support
investigations at the Nevada Test Site (NTS) and at Yucca Mountain, Nevada. The model area is an approximately
45,000 square-kilometer region of southern Nevada and California. The model simulates prepumping conditions of
the DVRFS and provides starting conditions for the development and calibration of a transient ground-water flow
model, (see "Larger Work Citation", Chapter A, page 8, for details). The lateral boundary encompassing the model
domain is a combination of no-flow boundaries resulting from physical barriers or hydraulic separation of flow regimes
(ground-water divides and [or] regional flow lines) and arbitrary lateral-flow (throughflow) boundaries where water is
allowed to flow across the lateral boundary.
The lateral boundary of the steady-state ground-water flow model by D'Agnese and others (2002) was used to
develop the subsequent lateral boundary of the transient ground-water flow model of the Death Valley regional
ground-water flow system (see "Larger Work Citation", figure A-2, p. 10).
The lateral boundary of the steady-state ground-water flow model by D'Agnese and others (2002) is one of many
layers in a geospatial database supporting the USGS DVRFS project. During this 5-year (1998-2004) project the
USGS, in cooperation with DOE and other Federal, State, and local agencies, developed this geospatial 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 and 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 data set author were checked by inspection using queries, and visually using a GIS. In addition, attributes were checked and evaluated as part of the review process associated with the publication of the source report (Larger Work Citation).
Lines forming the polygon feature join at endpoints to completely enclose the interior 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.
Line features in this data set were selectively compiled or generalized from hard copy and digital source maps. Line features defining the lateral boundaries of the ground-water flow models by D'Agnese and others (1997) and (IT Corporation, 1996a) were compiled to form the preliminary boundary for the DVRFS. Line features forming the west, northeast, and east portions of the boundary were subsequently modified to conform to a better understanding of the flow system using information from Cardinalli and others (1968) and Workman and others (2002). 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 to digital source maps using a GIS.

Digital data set derived from other source data.
Line features forming the lateral boundary of the ground-water flow model by D'Agnese and others (2002) were extracted or generalized from acquired hard copy and digital maps using a GIS system. Extracted line features were obtained using queries, while generalized line features were constructed by digitizing select lines of source maps. Line features forming the lateral boundaries of the ground-water flow models by D'Agnese and others (1997) and (IT Corporation, 1996a) were first compiled to form the preliminary boundary for the DVRFS. Line features forming the west, northeast, and east portions of the boundary were subsequently modified to conform to a better understanding of the flow system. For instance, line features forming the western boundary were modified to correspond to hydrographic area boundaries extracted from Cardinalli and others (1968). The northeast and eastern portions of the boundary were modified using hydrogeologic information from a digital geologic map by Workman and others (2002). The southern section was interpreted and digitized by the data set author (Point of Contact) to enclose the area of interest. Line features were modified in some areas to conform to the topographic divides of USGS Digital Elevation Models (DEM).
