As the Sparta aquifer is a heavily used aquifer, is the sole source of groundwater for many parishes in Louisiana, and recent withdrawals have exceeded the Sparta\u2019s natural recharge, a more frequent compilation of water usage for the Sparta aquifer in Louisiana is needed to inform State conservation groups and efforts, private and public entities, and to feed groundwater models.\nThis data release contains water withdrawn for public supply, thermoelectric, and industrial use from the Sparta aquifer in 2023, tabulated by parish and water-use category.  The estimated public-supply withdrawals in 2023 from the Sparta aquifer in Louisiana were 34 million gallons per day (Mgal/d) and industrial water was 21 Mgal/d, totaling to approximately 55 Mgal/d. There were no withdrawals for power generation.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13667MU", "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.682cacb0d4be021a0d6b72f2.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_682cacb0d4be021a0d6b72f2", "keyword": ["Louisiana", "Sparta aquifer", "USGS:682cacb0d4be021a0d6b72f2", "biota", "groundwater", "industry", "power generation", "public supply", "water use"], "modified": "2025-09-12T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-94.0800, 31.2539, -91.6063, 33.0853", "theme": ["geospatial"], "title": "Public-supply and industrial water withdrawals from the Sparta aquifer by parish in Louisiana, 2023"}
