USGS Water-Year Summary 2021
LOCATION - Lat 43°44'54", long 99°33'22" referenced to North American Datum of 1927, in SE 1/4 SW 1/4 sec.03, T.103 N., R.73 W., Lyman County, SD, Hydrologic Unit 10140204, on left bank at downstream side of bridge on State Highway 47, 1.5 mi downstream from Wagner Draw, 1.8 mi upstream from high-water line of Lake Francis Case, and 8.8 mi southwest of Oacoma.
DRAINAGE AREA - 9,915 mi² of which 60 mi² probably is noncontributing.
REVISIONS HISTORY - WSP 1309: 1929-30(M). WDR SD-10-1: Drainage area.
PERIOD OF RECORD - August 1928 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 1,378.40 ft above NAVD88.  Prior to conversion to NAVD88, datum was published as 1,377.29 ft above NGVD29. See WSP 1709, 1729, or 1917 for history of changes prior to Feb. 27, 1960.
REMARKS - Accuracy of records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years. For water years 2014 onward, records good except those below 1000 ft³/s, which are fair and those for estimated discharges, which are poor. Satellite data-collection platform at station. Suspended sediment samples collected with each discharge measurement.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 51,900 ft³/s, Mar. 30, 1952, gage height, 15.40 ft, site and datum then in use. Minimum daily discharge, 0.00 ft³/s, Aug. 14, 1971, no flow for some days in 1971, 1974, 1976, 1980, 1989, and 2006.
PERIOD OF RECORD - October 1945 to September 1953, October 1968 to September 1969, October 1971 to current year.
PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: October 1974 to September 1976, October 1977 to September 30, 1981. WATER TEMPERATURE: October 1974 to September 1976, October 1978 to September 1988. SUSPENDED-SEDIMENT DISCHARGE: October 1971 to September 1976, October 1981 to current year.
REMARKS - Accuracy of records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years. For water years 2014 onward, sediment discharge records good except those for, Oct. 1, 2018 to Oct. 8, 2019 which are fair, and those for estimated daily concentrations, which are fair. Observer collects samples on a daily basis during open water periods. Sediment-discharge records prior to Oct. 1, 1971, on file in the District Office, U.S. Army Corps of Engineers, Omaha, NE.
EXTREMES FOR PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Maximum daily, 1,950 microsiemens, Aug. 8, 1980; minimum daily, 370 microsiemens, Mar. 17, 1975. WATER TEMPERATURE: Maximum daily, 33.5°C, Jul. 18, 1986; minimum daily, -1.0°C on many days during winter periods. SEDIMENT CONCENTRATION: Maximum daily mean, 72,300 mg/L, Apr. 15, 1974; minimum daily mean, 11 mg/L, Aug. 5, 2002. SEDIMENT LOAD: Maximum daily, 1,640,000 tons, May 17, 1982; minimum daily, 0 ton, July 17-23, 1974, Aug. 29 to Sept. 9, 13, 1976, Aug. 11-23, 26 to Sept. 5, 1989, and Aug. 5-13, 2006.
