USGS Water-Year Summary 2020
LOCATION - Lat 43°00'08", long 115°12'09" referenced to North American Datum of 1983, in NW 1/4 NW 1/4 SW 1/4 sec.07, T.5 S., R.11 E., Elmore County, ID, Hydrologic Unit 17050101, King Hill quad., on right bank, 200 ft south of railroad tracks at King Hill, 20 mi downstream from Malad River, and at mile 546.6.
DRAINAGE AREA - 35,800 mi².
REVISIONS HISTORY - WSP 1317: 1935(M). WDR ID-76-1: 1974.
PERIOD OF RECORD - May 1909 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 2,492.3 ft above NGVD of 1929 (stadia levels). Nonrecording gage May 13, 1909 to Mar. 1, 1910, on left bank at present site at datum 2.20 ft higher. Nonrecording gage Mar. 7 to Aug. 16, 1910, 0.8 mi upstream at different datum. Nonrecording gage Aug. 17, 1910 to Oct. 7, 1928, at present site and datum.
REMARKS - Flow regulated by American Falls Reservoir, 168.4 mi upstream and irrigation diversions at Milner Dam. Diurnal fluctuation caused by hydroelectric power plant near Bliss. At times, practically entire flow is diverted at Milner during irrigation seasons; only minor diversions below Milner; flow at King Hill is then derived largely from springs and seepage entering below Milner within the Twin Falls tract. Diversions above station for irrigation of about 2,450,000 acres, of which about 675,000 acres are irrigated by withdrawals from ground water (1966 determination). Inflow from Clover Creek (station 13154400) may be significant during snowmelt runoff periods some years.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge observed, 47,200 ft³/s June 22, 1918, gage height, 16.3 ft, from rating curve extended above 30,000 ft³/s; minimum observed, 1,250 ft³/s Jan. 10, 1950, when flow was cut for gage repairs, gage height, 1.75 ft; minimum daily, 4,760 ft³/s June 7-9, Aug. 15, 16, 1910.
PERIOD OF RECORD - SPECIFIC CONDUCTANCE: March 1951 to September 1980 (discontinued). WATER TEMPERATURE: March 1951 to September 1980, June to September 1993, June to September 1994, July to September 1995, July to September 1996, May to September 2001, June to September 2002, July 2004 to current year.
REMARKS - Numerical uncertainty is not currently computed for time-series water-quality records but qualitative ratings are provided based on professional judgment.
  • Water Year 2014: Records good. There are 21 days of missing/deleted data from Oct. 1 to Sept. 30. 94.2% of the daily values will be reported.
  • Water Year 2015: Records good. There are 2 days of missing/deleted data from Oct. 1 to Sept. 30. 99.5% of the daily values will be reported.
  • Water Year 2016: Records good.
  • Water Year 2017: The practice of using qualitative ratings to describe data accuracy was discontinued in water year 2017.
