These simulated potentiometric surface contours represent prepumping (or steady-state) conditions for model layer 1 of the Death Valley regional ground-water flow system (DVRFS), an approximately 45,000 square-kilometer region of southern Nevada and California. The numerical ground-water flow model simulates prepumping conditions before 1913 and transient-flow conditions from 1913 to 1998 after pumping of ground water began. The DVRFS transient ground-water flow model is the most recent in a number of regional-scale models 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 (see "Larger Work Citation",...

This digital geospatial data set contains the locations, values, and uncertainties of hydraulic-head observations used in the calibration of the transient model of the Death Valley regional ground-water flow system (DVRFS). The hydraulic-head observations were developed by compositing one or more water-levels measured in wells throughout the DVRFS model domain, a 45,000 square-kilometer region of southern Nevada and California. To develop hydraulic-head observations, nearly all available water levels for the DVRFS region through 2004 were compiled in Ground-Water Site Inventory (GWSI), the ground-water component of the U.S. Geological Survey (USGS) National Water Information System (NWIS) database. Water levels...

This digital dataset defines the surface traces of regional geologic structures designated as potential ground-water flow barriers in an approximately 45,000 square-kilometer area of the Death Valley regional ground-water flow system (DVRFS) in southern Nevada and California. Most geologic structures representing potential flow barriers were faults that were identified on the basis of length, offset, type of slip, orientation with respect to predominate ground-water flow directions, the location of springs, abrupt water level offsets, and hydraulic characteristics (Sweetkind and others, 2004). A subset of the potential ground-water flow barriers was incorporated into a transient ground-water flow model of the DVRFS...

This digital data set defines the boundary of the southwestern Nevada volcanic field (SWNVF), an area of thick, regionally distributed volcanic rocks within the Death Valley regional ground-water flow system (DVRFS), a 100,000-square-kilometer region of southern Nevada and California. The SWNVF boundary encompasses an approximate 12,000 square-kilometer region and is based on a map of hydrogeologic controls on ground-water flow by Laczniak and others (1996). The SWNVF is characterized in part by a thick section of regionally distributed welded tuffs derived from a central complex of nested calderas that erupted from about 16 Ma to 5 Ma. The SWNVF boundary defines the extent of these particular volcanics and was...

Layered geospatial PDF 7.5 Minute Quadrangle Map. Layers of geospatial data include orthoimagery, roads, grids, geographic names, elevation contours, hydrography, and other selected map features. This map is derived from GIS (geospatial information system) data. It represents a repackaging of GIS data in traditional map form, not creation of new information. The geospatial data in this map are from selected National Map data holdings and other government sources.

This dataset was created by overlaying connectivity model outputs for grizzly bear, black bear, lynx, wolverine, forest specialist species, and forest biome dwellers where they intersect the region’s major roads. It was used in conjunction with future traffic volume projections to identify priority sites for mitigating road impacts on wildlife. This project investigated the potential impacts of future housing development on traffic to determine where increased traffic from housing development will impact habitat connectivity for large carnivores. The focus of this study was Flathead and Lincoln counties in northwestern Montana. The main goal was to maintain wildlife habitat connectivity across transportation corridors...

This digital data set is a compilation of reference points representing surface-water features, ground-water levels, and topographic settings in California that were used for the regional ground-water potential map by Bedinger and Harrill (2004). The regional ground-water potential map was developed to assess potential interbasin flow in the Death Valley regional ground-water flow system (DVRFS), a 100,000-square-kilometer region of southern Nevada and California. To obtain an adequate network of control points, Bedinger and Harrill (2004) also used regional potential altitudes derived from springs and deep well data. A set of general guidelines was developed to relate regional ground-water potential to these more...

The High Resolution National Hydrography Dataset Plus (NHDPlus HR) is an integrated set of geospatial data layers, including the best available National Hydrography Dataset (NHD), the 10-meter 3D Elevation Program Digital Elevation Model (3DEP DEM), and the National Watershed Boundary Dataset (WBD). The NHDPlus HR combines the NHD, 3DEP DEMs, and WBD to create a stream network with linear referencing, feature naming, "value added attributes" (VAAs), elevation-derived catchments, and other features for hydrologic data analysis. The stream network with linear referencing is a system of data relationships applied to hydrographic systems so that one stream reach "flows" into another and "events" can be tied to and traced...
