The High Plains aquifer underlies approximately 112.6 million acres (176,000 square miles) in parts \nof eight States: Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. \nThe aquifer's saturated thickness ranges from near zero to about 1,200 feet (Weeks and Gutentag, 1981). \nWater-level declines occurred in parts of the High Plains aquifer soon after the onset of substantial irrigation \nwith groundwater (about 1950) (Luckey and others, 1981). This data set was generated in ESRI ArcInfo \nWorkstation Version 9.3, which is a geographic information system (GIS), using an aquifer base raster \ndata set, saturated-thickness data from wells measured in 2009 and from some additional wells in New \nMexico, which were measured in 2005 through 2008, and a published map of the aquifer's saturated \nthickness in 1980 (Weeks and Gutentag, 1981). For this data set, (1) areas that Gutentag and others \n(1984) delineated as areas of \"little or no saturated thickness\" and (2) areas, generally near the aquifer \nboundary, with interpolated saturated thickness less than zero were set to a saturated thickness of 10 feet.\nREFERENCES CITED -- \nGutentag, E.D., Heimes, F.J., Krothe, N.C., Luckey, R.R., and Weeks, J.B., 1984, \nGeohydrology of the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming: \nU.S. Geological Survey Professional Paper 1400-B, 63 p.\nLuckey, R.R., Gutentag, E.D., and Weeks, J.B., 1981, \nWater-level and saturated-thickness changes, predevelopment to 1980, in the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming: \nU.S. Geological Survey Hydrologic Investigations Atlas HA-652, 2 sheets, scale 1:2,500,000. \nWeeks, J.B., and Gutentag, E.D., 1981, \nBedrock geology, altitude of base, and 1980 saturated thickness of the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming: \nU.S. Geological Survey Hydrologic Investigations Atlas HA-648, 2 sheets, scale 1:2,500,000.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9WMRZBN", "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.bf90ffef-ba16-4994-9ac3-0f49a91c12da.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_bf90ffef-ba16-4994-9ac3-0f49a91c12da", "keyword": ["Colorado", "Great Plains", "High Plains", "High Plains aquifer", "Kansas", "Nebraska", "New Mexico", "Ogallala aquifer", "Oklahoma", "South Dakota", "Texas", "USGS:bf90ffef-ba16-4994-9ac3-0f49a91c12da", "Wyoming", "aquifers", "geoscientificInformation", "ground water", "groundwater", "inlandWaters", "saturated thickness"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-106.016217, 31.598356, -96.225303, 43.806420", "theme": ["geospatial"], "title": "Saturated thickness, High Plains aquifer, 2009"}
