This dataset shows current\u2010year (2021) groundwater\u2010level altitudes for each aquifer, 1\u2013year (2020\u201321), 5\u2010year (2016\u201321) groundwater\u2010level changes for each aquifer, long\u2010term (1990\u20132021 and 1977\u20132021) groundwater\u2010level changes for the Chicot and Evangeline aquifers (undifferentiated), and long\u2010term (2000\u20132021) groundwater\u2010level change for the Jasper aquifer. The groundwater\u2010level measurements from which the dataset was built are stored in the USGS National Water Information System (NWIS) (http://doi.org/10.5066/F7P55KJN) and are accessible through the NWIS Web Interface. In 2021, measured groundwater-level-altitudes for the Chicot and Evangeline aquifers (undifferentiated) ranged from about 295 feet (ft) below the North American Vertical Datum of 1988 to about 214 ft above datum. Measured groundwater-level-altitudes for Jasper aquifer ranged from about 235 ft below datum to about 272 ft above datum. This dataset was created by the USGS 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.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9T8FJWO", "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.61981a3cd34eb622f692ef25.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_61981a3cd34eb622f692ef25", "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:61981a3cd34eb622f692ef25", "Walker County", "Waller County", "aquifer", "elevation", "groundwater", "groundwater-level altitude", "hydrology", "hypsometry", "subsidence"], "modified": "2022-08-22T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-96.0894, 28.9269, -94.6800, 30.6028", "theme": ["geospatial"], "title": "Groundwater-Level Altitudes and Long-Term Groundwater-Level Changes in the Chicot and Evangeline (Undifferentiated) and Jasper Aquifers, Greater Houston area, Texas, 2021"}
