This digital data set defines the subregions of the transient ground-water flow model of the
Death Valley regional ground-water flow system (DVRFS). Subregions are used to more
readily describe and evaluate the source, occurrence, and movement of ground water within
and between the smaller areas of the DVRFS, which is an approximately 45,000 square-
kilometer region of southern Nevada and California. The subregions, first described by D'Agnese
and others (1997), consist of a northern, central, and southern subregion. The subregions are
defined by grouping ground-water sections into ground-water basins and ultimately grouping
ground-water basins into ground-water subregions. Where applicable, ground-water flow paths
were used to modify the section boundaries so that the basin and subregion boundaries do not
always coincide with the section boundaries. The subregions, basins, and sections are used for
descriptive purposes only and do not define independent flow systems. The subregions, basins,
and sections are delineated primarily on (1) location of recharge areas; (2) regional hydraulic
gradients; (3) distribution of aquifers, structures, and confining units that affect flow; (4) location
of major discharge areas; and (5) hydrochemical composition of the ground water.
The subregions of the DVRFS were developed to evaluate and describe the
DVRFS at a sub-regional scale. Specifically, the DVRFS subregions are used for analyzing
ground-water flow by subregions, basins, and sections; and for describing specific areas within
the DVRFS.
The subregions of the DVRFS data set are one of many layers in a geospatial database supporting
the USGS DVRFS project. During that 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. Those 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
and represent 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 (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 (OCRWM) Yucca Mountain Project (YMP), 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 polygons join at endpoints to completely enclose areas. 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 features in this data set were originally digitized from hard copy in Cardinalli and others (1968) and Harrill and Prudic (1998). The resulting digital data set was later modified by D'Agnese and others (2002) and Belcher (2004). The data set is complete and is not anticipated to change.
The accuracy of the compiled digital line features in the data set is based upon the accuracy of source maps and digital data sets which are compiled to meet National Map Accuracy Standards. Horizontal positional accuracy was tested by visually comparing these line features to source maps using a GIS and hardcopy plots.

Output data set.
Polygon features defining subregions within the DVRFS were developed by attributing hydrographic sections. Polygons representing hydrographic sections, were modified from Cardinalli and others (1968) and Harrill and Prudic (1998). Polygon features were extracted or generalized from acquired hard copy and digital maps using a GIS. Extracted line features were obtained using queries, while generalized line features were constructed by digitizing select lines from source maps. D'Agnese and others (1997) defined the hydrologic sections to form the ground-water basins and subregions based on distinct flow paths. The definitions of hydrologic sections, ground-water basins and subregions were used for descriptive purposes, and did not define discrete independent flow systems. D'Agnese and others (2002) expanded the areal extent of the 1997 version of the DVRFS subregion map to include the area of the DVRFS steady-state model domain. The DVRFS subregion map was subsequently modified by Faunt and others (2004) for use with the DVRFS transient ground-water flow model.
