Reservoir surface areas were determined using National Inventory of Dams Reservoir Surface area, NHDPlus Waterbody area, and National Land Cover Data (NLCD) open water body area as data sources. National Inventory of Dams were indexed on NHDPlus V2.1 using several sources and methods which are described in detail in the Process_Description section. The open-water classification in the NLCD was used to extract open water areas.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7765D7V", "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.5d038e0ce4b0e3d311562c59.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5d038e0ce4b0e3d311562c59", "keyword": ["Inlandwaters", "NAWQA", "NHDPlus", "NID", "National Inventory of Dams", "SPARROW", "USGS:5d038e0ce4b0e3d311562c59", "dams", "reservoir storage", "reservoir surface area"], "modified": "2026-03-26T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-127.9108, 23.2435, -65.3278, 51.6574", "theme": ["geospatial"], "title": "Select Hydrologic Modification Attributes: Attributes for Surface Water Impoundments"}
