USGS Water-Year Summary 2021
LOCATION - Lat 44°54'38", long 98°28'18" referenced to North American Datum of 1927, in NW 1/4 NW 1/4 NW 1/4 sec.31, T.117 N., R.63 W., Spink County, SD, Hydrologic Unit 10160006, on left bank near downstream side of county bridge, 2.8 mi northeast of Redfield, and 0.7 mi downstream from Turtle Creek.
DRAINAGE AREA - 13,886 mi² of which 2,007 mi² probably is noncontributing.
REVISIONS HISTORY - WDR SD-09-1: 2009 (maximum daily average). WDR SD-11-1: Drainage area. Discharge for the period Oct. 15, 2018, to Oct. 16, 2019, was revised on May 24, 2020, based on changes to the stage-discharge rating.
PERIOD OF RECORD - March 1950 to current year. Crest-stage partial record, October 1990 to September 1997.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 1,240.50 ft above NAVD88. Prior to conversion to NAVD88 datum was published as 1,239.50 ft above NGVD29.  From Oct. 1, 1981, to Oct. 8, 1986, water-stage recorder at site 0.6 mi downstream at datum 1,239.50 ft above NGVD29. From March 1950 to July 25, 1951, nonrecording gage and from July 26, 1951, to Sept. 30, 1981, water-stage recorder at site 4.5 mi downstream from present site and at different datum.

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 for estimated discharges, which are poor. Low flow regulated by dams forming Arrowwood and Jim Lakes, combined capacity, 16,530 acre-ft, and by dam forming Jamestown Reservoir, capacity, 229,470 acre-ft, since May 1953, and by dam forming Pipestem Reservoir, capacity, 147,000 acre-ft, since 1973. Flow below 100 ft³/s for water years 1964-79 may be unreliable because of wind effect. Satellite data-collection platform at station.

EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 17,000 ft³/s, Apr. 3, 1997, gage height, 29.92 ft; maximum gage height, 31.10 ft, Apr. 6, 1997, from floodmark; minimum daily discharge, 0.00 ft³/s, Jan. 25, 1951, no flow for many days in some years.
