This report documents the measurement and computation of flow through the Lockport Controlling Works (LCW) and the Lockport Powerhouse. This analysis aided in evaluation of the ratings at both structures, and the development of new ratings at the controlling works. The LCW structure consists of seven 30-feet (ft) wide sluice gates and is used to divert water from the CSSC and into the Des Plaines River. The flow regimes for the sluice gate included both free and submerged weir. Forty and 491 flow values from U.S. Geological Survey streamflow-gaging stations were used to develop equations describing free- and submerged-weir flow, respectively, through the sluice gates. The equations were developed for canal headwater elevations ranging from -7.0 to -10.5 ft Chicago City Datum (CCD), and tailwater (Des Plaines River at Lockport) to headwater (CSSC-LCW-Base) ratios ranging from 0.31 to 0.66. The Lockport Powerhouse structure consists of nine 9-ft wide by 14-ft high sluice gates and two 10-ft diameter turbines. Both tailwater and no-tailwater effect flow regimes occurred during nine measurements. Also, the canal headwater elevations ranged from -2.74 to -8.45 ft CCD, and the gates were configured six different ways during the measurements.", "description": "vi, 25 p.", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Straub, Timothy D. tdstraub@usgs.gov", "givenName": "Timothy D.", "familyName": "Straub", "email": "tdstraub@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-5896-0851", "url": "https://orcid.org/0000-0002-5896-0851"}, "affiliation": [{"@type": "Organization", "name": "Illinois Water Science Center", "url": "https://www.usgs.gov/centers/cm-water"}]}, {"@type": "Person", "name": "Hortness, Jon hortness@usgs.gov", "givenName": "Jon", "familyName": "Hortness", "email": "hortness@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-9809-2876", "url": "https://orcid.org/0000-0002-9809-2876"}}, {"@type": "Person", "name": "Johnson, Kevin K. johnsonk@usgs.gov", "givenName": "Kevin K.", "familyName": "Johnson", "email": "johnsonk@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0003-2703-5994", "url": "https://orcid.org/0000-0003-2703-5994"}, "affiliation": [{"@type": "Organization", "name": "Illinois-Iowa-Missouri Water Science Center", "url": "https://www.usgs.gov/centers/cm-water"}, {"@type": "Organization", "name": "Illinois Water Science Center", "url": "https://www.usgs.gov/centers/cm-water"}, {"@type": "Organization", "name": "Central Midwest Water Science Center", "url": "https://www.usgs.gov/centers/cm-water"}]}, {"@type": "Person", "name": "Duncker, James J. jduncker@usgs.gov", "givenName": "James J.", "familyName": "Duncker", "email": "jduncker@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0001-5464-7991", "url": "https://orcid.org/0000-0001-5464-7991"}, "affiliation": [{"@type": "Organization", "name": "Illinois-Iowa-Missouri Water Science Center", "url": "https://www.usgs.gov/centers/cm-water"}, {"@type": "Organization", "name": "Illinois Water Science Center", "url": "https://www.usgs.gov/centers/cm-water"}, {"@type": "Organization", "name": "Central Midwest Water Science Center", "url": "https://www.usgs.gov/centers/cm-water"}]}], "funder": [{"@type": "Organization", "name": "Illinois Water Science Center", "url": "https://www.usgs.gov/centers/cm-water"}], "spatialCoverage": [{"@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/6252001"}, {"@type": "Place", "additionalType": "state", "name": "Illinois", "url": "https://geonames.org/4896861"}, {"@type": "Place", "geo": [{"@type": "GeoShape", "additionalProperty": {"@type": "PropertyValue", "name": "GeoJSON", "value": {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[-88.25, 41.5], [-88.25, 42.25], [-87.5, 42.25], [-87.5, 41.5], [-88.25, 41.5]]]}}]}}}, {"@type": "GeoCoordinates", "latitude": 41.875, "longitude": -87.875}]}]}
