DRAINAGE AREA - 3,240 mi².

SURFACE-WATER RECORDS

PERIOD OF RECORD - August 1935 to current year. Records for January 1895 to July 1897 (published as "at Payette" in 18th and 19th Annual Reports) have been found to be unreliable and should not be used.

GAGE - Water-stage recorder. Elevation of gage datum is arbitrary.

REMARKS - Flow regulated by Deadwood Reservoir, Cascade Reservoir beginning November 1947, other smaller reservoirs, and to some extent by Black Canyon Dam 34.6 mi upstream, where flow is regulated by diversion and gate operation at dam. Diversions above station for irrigation of about 196,000 acres, of which about 100 acres are irrigated by withdrawals from ground water, about 5,100 acres are located below station, and about 53,000 acres are in adjacent basins (1966 determination).

EXTREMES FOR PERIOD OF RECORD - Maximum daily discharge, 32,000 ft³/s, Jan. 2, 1997; minimum, 17 ft³/s, June 25, 2001, gage height, 3.09 ft (result of irrigation diversion upstream); minimum daily, 127 ft³/s, Aug. 15, 1991.

WATER-QUALITY RECORDS

PERIOD OF RECORD - Continuous water temperature data were collected from August to September 1997, July to September 1998, May to September 1999, November 2001 to October 2002, July to September 2003, April 2016 to September 2018 (discontinued).

REMARKS - Numerical uncertainty is not currently computed for time-series water-quality records but qualitative ratings are provided based on professional judgment.

Water Year 2016: Records good.

Water Year 2017: The practice of using qualitative ratings to describe data accuracy was discontinued in water year 2017.
