WATER-DISCHARGE RECORDS

PERIOD OF RECORD.--October 1938 to February 1940 (monthly records only), March 1940 to September 1954; July 1985 to current year. For a complete listing of historical data available for this site, see http://waterdata.usgs.gov/co/nwis/inventory/?site_no=07106000

GAGE.--Water-stage recorder with satellite telemetry and crest-stage gage. Elevation of gage is 5,355 ft above NGVD of 1929, from topographic map. Sept. 18, 1938 to Mar. 1, 1940, nonrecording gage at site 40 ft upstream on right bank at different datum. Mar. 2, 1940 to Sept. 30, 1954, at site 290 ft upstream on right bank at different datum. July 2, 1985 to Sept. 2, 1987, at site 590 ft upstream on right bank at different datum. Sept. 3, 1987 to Mar. 12, 1990, at site 1,190 ft upstream on right bank at different datum. March 13, 1990 to October 30, 2002, at site 90 ft upstream on right bank.

REMARKS.--Records fair except for estimated daily discharges and those above 1,000 ft3/s, which are poor. Natural flow of stream affected by storage reservoirs, power developments, ground-water withdrawals, transmountain diversions, diversions for irrigation and municipal use, return flows from irrigated areas, and flows from sewage-treatment plants.

EXTREMES OUTSIDE PERIOD OF RECORD.--Maximum stage known, 14.4 ft, at different datum, May 30, 1935, discharge undetermined. Floods of May 1935 and June 1965 probably exceeded flood of May 1940.
