Dissolved oxygen returned to background levels downstream of Fall Creek Dam on December 18, 2012, approximately 1 day after the end of the drawdown operation.", "description": "vi, 80 p.", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Bragg, Heather M. hmbragg@usgs.gov", "givenName": "Heather M.", "familyName": "Bragg", "email": "hmbragg@usgs.gov", "affiliation": [{"@type": "Organization", "name": "Oregon Water Science Center", "url": "https://www.usgs.gov/centers/oregon-water-science-center"}]}, {"@type": "Person", "name": "Schenk, Liam N. lschenk@usgs.gov", "givenName": "Liam N.", "familyName": "Schenk", "email": "lschenk@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-2491-0813", "url": "https://orcid.org/0000-0002-2491-0813"}, "affiliation": [{"@type": "Organization", "name": "Oregon Water Science Center", "url": "https://www.usgs.gov/centers/oregon-water-science-center"}]}], "funder": [{"@type": "Organization", "name": "Oregon Water Science Center", "url": "https://www.usgs.gov/centers/oregon-water-science-center"}], "spatialCoverage": [{"@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/6252001"}, {"@type": "Place", "additionalType": "state", "name": "Oregon", "url": "https://geonames.org/5744337"}, {"@type": "Place", "additionalType": "unknown", "name": "Fall Creek Lake", "url": "https://geonames.org/5726151"}, {"@type": "Place", "geo": [{"@type": "GeoShape", "additionalProperty": {"@type": "PropertyValue", "name": "GeoJSON", "value": {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[-122.7, 43.6], [-122.7, 44.0], [-122.5, 44.0], [-122.5, 43.6], [-122.7, 43.6]]]}}]}}}, {"@type": "GeoCoordinates", "latitude": 43.8, "longitude": -122.60000000000001}]}]}
