PERIOD OF RECORD - June 1925 to January 1926, May 1934 to September 1968, July 1971 to current year.

GAGE - Water-stage recorder. Elevation of gage is 3,330 ft, referenced to the North American Vertical Datum of 1988. May 21, 1925 to Feb. 8, 1926, nonrecording gage at site 500 ft downstream at different elevation. Apr. 19, 1934 to Sept. 30, 1955, at previous site at elevation. May 18, 1955 to Apr. 25, 1960 and Sept. 24, 1962 to Sept. 30, 1968, auxiliary crest-stage gage. Oct. 1, 1955 to Sept. 30, 1968, nonrecording gage at bridge 670 ft upstream at previous elevation.
