Resource Abstract:
- description: This geodatabase includes spatial datasets that represent the Basin and Range basin-fill aquifers in the States
of Arizona, California, Idaho, Nevada, New Mexico, Oregon, and Utah. Included are: (1) polygon extents; datasets that represent
the aquifer system extent, the entire extent subdivided into subareas or subunits, and any polygon extents of special interest
(outcrop areas, no data available, areas underlying other aquifers, anomalies, for example), (2) contours: thickness contours
used to generate the surface rasters in subarea 4 (Arizona), (3) modified source raster datasets for subareas 1 and 3, (4)
corrected altitudes of top and bottom surface rasters of the entire aquifer. The thickness contours and modified surface rasters
are supplied for reference. The extent of the Basin and Range basin-fill aquifer is from the linework of the Basin and Range
aquifer extent maps in U.S. Geological Survey Hydrologic Atlas 730 Chapters B and C, and a digital version of the aquifer
extent presented in the Groundwater Atlas of the United States (the U.S. Geological Survey Hydrologic Atlas. The Basin and
Range basin-fill aquifer has no aquifer subunits, but is defined by five subareas: 1. Subarea 1 is the area that overlies
the Basin and Range Carbonate aquifer, which was the subject of U.S. Geological Survey Scientific Investigations Report 2010-5193
(USGS SIR 2010-5193). 2. Subarea 2 is the area of a different aquifer system, which is set to null for use within the Basin
and Range basin-fill aquifer from U.S. Geological Survey Principal Aquifers, 2003 (USGS Circular 1323, Figure 2) 3. Subarea
3 is the area of the Basin and Range basin-fill aquifer that was the subject of U.S. Geological Survey Geophysical Map 1012
(USGS GP-1012) and not covered by USGS SIR 2010-5193 or the Basin and Range basin-fill aquifer in Arizona, Arizona Geological
Survey, Digital Geological Map 52 (AZGS DGM-52). Top of aquifer is land surface. USGS GP-1012 dataset is depth from land surface
to basin bottom. 4. Subarea 4 is the area of the 01BSNRGB aquifer in Arizona, (AZGS DGM-52) 5. Subarea 5 areas are in the
Basin and Range basin-fill extent areas that do not have top/bot defined. The resultant top and bottom surface rasters for
each subarea were merged into surface rasters of the top and bottom of the entire Basin and Range basin-fill aquifer within
a GIS using tools that create hydrologically correct surfaces from contour data, deriving the altitude from the thickness
(depth from the land surface), and merging the subareas into a single surface. The primary tools were a version of "Topo
to Raster", and "Mosaic to New Raster" used in ArcGIS, ArcMap, Esri 2014.; abstract: This geodatabase includes
