The aquifer system is \nsituated in the eastern portion of the Great Basin Province of the western United States. \nThe eastern Great Basin is experiencing rapid population growth and has some of the highest \nper capita water use in the Nation. These factors, combined with the arid setting, have levied \nintensive demand upon current groundwater resources and, thus, predictions of future shortages. \nBecause of the large regional extent of the aquifer system, rapid growth in the region, and the \nreliance upon groundwater for urban populations, agriculture, and native habitats, the GBCAAS \nwas selected by the USGS Water Resources program as part of the National Water Census \nInitiative to evaluate the Nation's groundwater availability.\n\t\t\nThis dataset consists of potentiometric contours, control points used to guide the creation \nof the contours, and a grid of 2 square-mile cells used to average the water-level value of \nselected control points. Control points are based on water-level measurements at well and \nspring locations from the USGS National Water Information System (NWIS, Mathey, 1998). \nAdditional control points were derived from estimates of water-level altitudes in perennial \nmountain streams based on National Hydrography Dataset (NHD, 1999) stream reaches.\n\t\t\nReferences cited:\n\t\t\nMathey, Sharon B., ed., 1998, National Water Information System (NWIS): \nU.S. Geological Survey Fact Sheet 027-98, 2 p., \nAccessed January 14, 2009 at &lt;https://pubs.usgs.gov/fs/FS-027-98/fs-027-98.pdf&gt;\n\t\t\nU.S. Geological Survey, 1999, National Hydrography Dataset: \nU.S. Geological Survey Fact Sheet 106-99, \naccessed March 2007 at http://erg.usgs.gov/isb/pubs/factsheets/fs10699.html", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P99PLTKO", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.fb7eb0e2-8e90-4e51-baa0-51850e05afd4.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_fb7eb0e2-8e90-4e51-baa0-51850e05afd4", "keyword": ["California", "Great Basin", "Groundwater-level altitude", "Idaho", "Nevada", "Potentiometric contour", "USGS:fb7eb0e2-8e90-4e51-baa0-51850e05afd4", "Utah", "Water-level altitude", "geoscientificInformation", "inlandWaters"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-118.647404, 35.171686, -111.009994, 42.511846", "theme": ["geospatial"], "title": "1:1,000,000-scale potentiometric contours and control points for the Great Basin carbonate and alluvial aquifer system of Nevada, Utah, and parts of adjacent states"}
