The original datasets were provided by the Kansas City, Rock Island, and St. Louis districts of the U.S. Army Corp of Engineers. Structures were classified into 10 types which were further characterized by whether the structure was notched. Use of the term notch suggests variation in elevation along the length of the structure, either due to substantial erosion or managed height causing visual indication of non-uniform flow from aerial or satellite imagery.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1UUQGXS", "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.69b811bcb66b010d85582ed0.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_69b811bcb66b010d85582ed0", "keyword": ["Illinois", "Illinois River", "Mississippi River", "Missouri", "Missouri River", "USGS:69b811bcb66b010d85582ed0", "geomorphology", "geospatial datasets", "habitats", "inlandWaters"], "modified": "2026-06-24T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-94.8562, 36.9670, -88.0667, 41.5157", "theme": ["geospatial"], "title": "Managed structures in the Lower Missouri, Middle Mississippi, Upper Mississippi, and Illinois rivers, compiled and modified by University of Missouri and U.S. Geological Survey to quantify invasive carp habitat, 2024"}
