This dataset documents current\u2010year (2020) groundwater\u2010level altitudes for each aquifer, 5\u2010year (2015\u201020) groundwater\u2010level changes for each aquifer, long\u2010term (1990\u20102020 and 1977\u20102020) groundwater\u2010level changes for the Chicot and Evangeline aquifers, and long\u2010term (2000\u20102020) groundwater\u2010level change for the Jasper aquifer. The groundwater\u2010level measurements from which the dataset were built are stored in the USGS National Water Information System (NWIS) (http://dx.doi.org/10.5066/F7P55KJN) and are accessible through the NWIS  Web Interface.  \nIn 2020, groundwater-level-altitude contours for the Chicot aquifer ranged from 150 feet (ft) below the North American Vertical Datum of 1988 to 200 ft above datum. Groundwater-level-altitude contours for the Evangeline aquifer ranged from 250 ft below datum to 200 ft above datum. Groundwater-level-altitude contours for the Jasper aquifer ranged from 200 ft below datum to 250 ft above datum. In each aquifer, the highest and lowest groundwater-level altitudes were measured in relatively small, isolated areas. This dataset was created by the U.S. Geological Survey to provide resource managers, public officials, researchers, and the general public with ready access to accurate, impartial, scientific information regarding groundwater\u2010level changes and altitudes in Harris, Galveston, Fort Bend, Montgomery, Brazoria, Chambers, Grimes, Liberty, San Jacinto, Walker, and Waller Counties, Texas.  \nThese digital data accompany a U.S. Geological Survey Scientific Investigation Report by Braun and Ramage (2020).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P98IX48O", "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.5ed51aa482ce2832f047ee8c.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5ed51aa482ce2832f047ee8c", "keyword": ["Brazoria County", "Chambers County", "Chicot aquifer", "Evangeline aquifer", "Fort Bend County", "Galveston County", "Grimes County", "Harris County", "Houston", "Jasper aquifer", "Liberty County", "Montgomery County", "San Jacinto County", "Texas", "USGS:5ed51aa482ce2832f047ee8c", "Walker County", "Waller County", "aquifer", "elevation", "groundwater", "groundwater-level altitude", "hydrology", "hypsometry", "subsidence"], "modified": "2020-08-27T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-96.0894, 29.3003, -94.6800, 30.6028", "theme": ["geospatial"], "title": "Groundwater-level altitudes and long-term groundwater-level Changes in the Chicot, Evangeline, and Jasper aquifers, Houston-Galveston Region, Texas, 2020"}
