Data were recorded bihourly from 1 Jan 1985 \u2013 31 Dec 2016. For each location, pool elevation (ft), tailwater elevation (ft), head height (ft; calculated by the difference between pool elevation and tailwater elevation), discharge (cfs; when available) and total gate openness (sum of all open gates in ft), are given, where available. Open river conditions were calculated (0 = closed, 1 = open) for each two hour time period. Dam openness was assessed using the U.S. Army Corps of Engineers thresholds for open river conditions at each location.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7833R62", "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.5a4e9124e4b0d05ee8c66409.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5a4e9124e4b0d05ee8c66409", "keyword": ["Dresden Island Lock and Dam", "Illinois River", "La Grange Lock and Dam", "Marseilles Lock and Dam", "Peoria Lock and Dam", "Starved Rock Lock and Dam", "USGS:5a4e9124e4b0d05ee8c66409", "dam operation", "discharge", "highhead dams", "open river", "wicket dams"], "modified": "2021-06-08T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "theme": ["geospatial"], "title": "Assessing Techniques to Enhance Barrier Characteristics of High-head Navigation Dams on the Upper Illinois River: Data"}
