Resource Abstract:
- description: This dataset was created in support of a U.S. Geological Survey (USGS) study focusing on groundwater resources
in the Great Basin carbonate and alluvial aquifer system (GBCAAS). The GBCAAS is a complex aquifer system comprised of both
unconsolidated and bedrock formations covering an area of approximately 110,000 square miles. The aquifer system is situated
in the eastern portion of the Great Basin Province of the western United States. The eastern Great Basin is experiencing rapid
population growth and has some of the highest per capita water use in the Nation. These factors, combined with the arid setting,
have levied intensive demand upon current groundwater resources and, thus, predictions of future shortages. Because of the
large regional extent of the aquifer system, rapid growth in the region, and the reliance upon groundwater for urban populations,
agriculture, and native habitats, the GBCAAS was selected by the USGS Water Resources program as part of the National Water
Census Initiative to evaluate the Nation's groundwater availability. This dataset consists of potentiometric contours,
control points used to guide the creation of the contours, and a grid of 2 square-mile cells used to average the water-level
value of selected control points. Control points are based on water-level measurements at well and spring locations from the
USGS National Water Information System (NWIS, Mathey, 1998). Additional control points were derived from estimates of water-level
altitudes in perennial mountain streams based on National Hydrography Dataset (NHD, 1999) stream reaches. References cited:
