Beginning in the 1860s, anthropogenic changes to the river within Indiana resulted in downstream flooding and additional transport of sediment and nutrients. In 2015, the U.S. Geological Survey, in cooperation with the Indiana Department of Environmental Management, upgraded the gaging station Kankakee River at Shelby, Indiana, to include the collection of water-quality data. By relating continuously monitored water-quality data to discrete data collected from December 2015 through May 2018, linear regression was used to develop models for estimating concentrations of suspended sediment, total nitrogen, and total phosphorus. Developed regression models indicated a strong correlation between turbidity and specific conductance with suspended-sediment concentration (adjusted coefficient of determination equals 0.92, predicted residual error sum of squares equals 0.151), nitrate plus nitrite and specific conductance with total nitrogen (adjusted coefficient of determination equals 0.95, predicted residual error sum of squares equals 0.0248), and turbidity with total phosphorus (adjusted coefficient of determination equals 0.89, predicted residual error sum of squares equals 0.0103).Daily loads of suspended sediment, total nitrogen, and total phosphorus were computed as the product of daily mean regression model concentrations and daily mean streamflow. Rloadest models were used to compute daily loads of each constituent during gaps in regression model loads. For 2016 and 2017, the estimated annual suspended-sediment loads were 105,000 and 91,000 tons; estimated total nitrogen loads were 8,690 and 8,890 tons; and estimated total phosphorus loads were 265 and 236 tons, respectively.", "description": "Report: v, 13 p.; 2 Data Releases", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Lathrop, Timothy R.", "givenName": "Timothy R.", "familyName": "Lathrop", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-3568-1286", "url": "https://orcid.org/0000-0002-3568-1286"}, "affiliation": [{"@type": "Organization", "name": "Ohio-Kentucky-Indiana Water Science Center", "url": "https://www.usgs.govhttps://www.usgs.gov/centers/oki-water"}]}, {"@type": "Person", "name": "Downhour, Myles S.", "givenName": "Myles S.", "familyName": "Downhour", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0001-6677-412X", "url": "https://orcid.org/0000-0001-6677-412X"}, "affiliation": [{"@type": "Organization", "name": "Ohio-Kentucky-Indiana Water Science Center", "url": "https://www.usgs.govhttps://www.usgs.gov/centers/oki-water"}]}, {"@type": "Person", "name": "Bunch, Aubrey R. aurbunch@usgs.gov", "givenName": "Aubrey R.", "familyName": "Bunch", "email": "aurbunch@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-2453-3624", "url": "https://orcid.org/0000-0002-2453-3624"}, "affiliation": [{"@type": "Organization", "name": "Indiana Water Science Center", "url": "https://www.usgs.govhttps://www.usgs.gov/centers/oki-water"}, {"@type": "Organization", "name": "Ohio-Kentucky-Indiana Water Science Center", "url": "https://www.usgs.govhttps://www.usgs.gov/centers/oki-water"}, {"@type": "Organization", "name": "Indiana-Kentucky Water Science Center", "url": "https://www.usgs.govhttps://www.usgs.gov/centers/oki-water"}]}], "funder": [{"@type": "Organization", "name": "Ohio-Kentucky-Indiana Water Science Center", "url": "https://www.usgs.govhttps://www.usgs.gov/centers/oki-water"}], "spatialCoverage": [{"@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/6252001"}, {"@type": "Place", "additionalType": "state", "name": "Indiana", "url": "https://geonames.org/4921868"}, {"@type": "Place", "additionalType": "city", "name": "Shelby", "url": "https://geonames.org/5009586"}, {"@type": "Place", "additionalType": "unknown", "name": "Kankakee River Basin"}, {"@type": "Place", "geo": [{"@type": "GeoShape", "additionalProperty": {"@type": "PropertyValue", "name": "GeoJSON", "value": {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[-86.81396484375, 41.34897943069752], [-86.08337402343749, 41.34588656996287], [-86.08337402343749, 41.76721469421018], [-86.81259155273438, 41.76823896512856], [-86.81396484375, 41.34897943069752]]]}}]}}}, {"@type": "GeoCoordinates", "latitude": 41.55751301297388, "longitude": -86.44802741225249}]}]}
