DRAINAGE AREA - 69,200 mi².
REVISIONS HISTORY - WSP 1317: 1918. WSP 1567: 1910(M). WDR ID-76-1: 1975.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1910 to current year. Fragmentary gage-height record obtained by U.S. Weather Bureau since 1895. Monthly discharge only for October 1910, published in WSP 1317.
GAGE - Water-stage recorder. Datum of gage is 2,086.64 ft above NGVD of 1929. Prior to Oct. 1, 1914, nonrecording gage 0.2 mi downstream at different datum. Oct. 1, 1914 to Oct. 11, 1933, nonrecording gage, and Oct. 12, 1933 to Apr. 13, 1964, water-stage recorder, at site 0.3 mi upstream at same datum.
REMARKS - Flow regulated by many reservoirs above station. Diurnal fluctuation caused by hydroelectric plants upstream. Diversions above station for irrigation of about 3,650,000 acres, of which about 742,000 acres are irrigated by withdrawals from groundwater. In addition, approximately 7,300 acres are irrigated below station by diversions from Weiser River (1966 determination).
EXTREMES OUTSIDE PERIOD OF RECORD - Flood of Mar. 3, 1910, reached a stage of 17.1 ft, at site and datum 0.3 mi upstream, from reading on old U.S. Weather Bureau gage, discharge, 120,000 ft³/s. Flood in June 1894 was considerably higher.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 84,500 ft³/s Apr. 29, 1952, gage height, 14.67 ft, site and datum then in use; maximum gage height recorded, 15.55 ft, Dec. 20, 1972, backwater from ice jam; minimum discharge, 4,390 ft³/s June 7, 1992, gage height, 1.36 ft.
WATER-QUALITY RECORDS
PERIOD OF RECORD - Continuous water temperature data were collected from May to September 1999, November 2001 to October 2002, August to October 2003, and January 2005 to October 2015. Continuous turbidity data were collected December 2018 to November 2019.
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 except for Jan. 7 to Mar. 2, records fair.
  • Water Year 2015: Records good except for Mar. 15-26, records fair.
  • Water Year 2017: The practice of assigning qualitative accuracy rating to continuous water-quality data was discontinued in WY2017.
