LOCATION - Lat 44°08'39.65", long 103°27'14.66" referenced to North American Datum of 1927, in SE 1/4 SE 1/4 sec.12, T.2 N., R.5 E., Lawrence County, SD, Hydrologic Unit 10120111, on right bank at ranch 0.2 mi upstream from county line, 0.9 mi downstream from Jim Creek, and 4.5 mi southeast of Nemo.
DRAINAGE AREA - 94.2 mi².
REVISIONS HISTORY - WDR SD-10-1: Drainage area.
PERIOD OF RECORD - July 1945 to July 1947, May 1966 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 4,322.06 ft above North American Vertical Datum of 1988 (NAVD88). Prior to conversion to NAVD 88 datum was published as 4,320.27 ft above NGVD29 (USGS bench mark). July 1945 to July 1947 nonrecording gage at site 100 ft upstream at different datum. May 17, 1966, to June 9, 1972, water-stage recorder (destroyed by flood) and June 10, 1972, to Aug. 8, 1972, nonrecording gage, both at site 100 ft upstream at datum 2.00 ft higher.
REMARKS - Accuracy of records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years. For years 2014 onward, records good except for Feb. 10, 2016 to Apr. 3, 2016, which are fair, and estimated discharges, which are poor, unless otherwise noted. Satellite data-collection platform at station.
EXTREMES OUTSIDE PERIOD OF RECORD - Flood on June 12, 1907 (previously reported as 1911) reached a stage of about 16 ft, present datum with an estimated discharge of 16,000 ft³/s.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 30,100 ft³/s, June 9, 1972, from rating curve extended above 600 ft³/s on basis of slope-area measurement of peak flow; gage height, 20.40 ft, site and datum then in use, (22.0, ft present site and datum, from floodmarks).
