These data represent water surface elevations for Lake Powell at levels critical to the operation of Glen Canyon Dam, at 5 foot intervals from the \"Equalization Tier\" (\"Full Pool\") to \"Dead Pool\", and at maximum and minimum elevations each water year throughout Glen Canyon Dam's operating history. These data were created for Lake Powell in Arizona and Utah. These data were created by the U.S. Geological Survey, Southwest Biological Science Center, Grand Canyon Monitoring & Research Center by reclassifying \"Modified topobathymetric elevation data for Lake Powell\" (Jones and Root, 2021) at discrete elevation levels and converting them into vector format. These data can be used to visualize locations or resources in Lake Powell at various elevation levels as it continues to change.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.66c3a758d34e03388287a719.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13OE7QW", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_66c3a758d34e03388287a719", "keyword": ["Garfield County", "inlandWaters", "DEM", "Southwest Biological Science Center", "Lake Powell", "Utah", "Kane County", "Arizona", "surface-water level", "water resource management", "Grand Canyon Monitoring & Research Center", "USGS:66c3a758d34e03388287a719", "Escalante River", "U.S. Geological Survey", "Coconino County", "Glen Canyon Dam", "elevation", "USGS", "San Juan County", "Hite", "reservoir storage capacity", "hydrographic datasets", "environment", "flood inundation modeling", "San Juan River", "data release", "topobathymetric", "boundaries", "computer science", "Glen Canyon National Recreation Area", "natural resource management", "Colorado River", "adaptive management", "modeling", "bathymetry", "Glen Canyon", "Navajo Mountain", "inland bathymetry", "Page", "surface water (non-marine)", "digital elevation models"], "modified": "2024-09-06T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-111.6110, 36.8339, -110.1378, 38.0034", "theme": ["geospatial"], "title": "Lake Powell extent polygons at various elevations"}
