GAGE - Water-stage recorder and concrete control. Elevation of gage is 2,080 ft above NGVD of 1929, from topographic map. Prior to December 1919, nonrecording gage at site 0.5 mi downstream at different datum. December 1919 to July 1969, at site 0.4 mi downstream at different datum. July 1969 to September 1972, present gage used as supplementary gage. Oct. 1, 1973, to Feb. 25, 1974, supplementary gage at site 0.5 mi downstream at different datum.
EXTREMES FOR PERIOD OF RECORD - (1913-14 and since 1919) Maximum discharge, 3,720 ft³/s, Jan. 25, 1969, gage height, 5.40 ft, site and datum then in use, on basis of slope-area measurement of peak flow. The peak discharges on Dec. 25, 2003, Oct. 20, 27, 2004, and Jan. 9, 2005, were the result of debris flows, due to intense rain storms occurring where a wildfire had burned over 90 percent of the drainage basin in October 2003. The peak discharges for these events are unknown. Maximum gage height, 15.61 ft, Oct. 27, 2004, from floodmarks left by debris flow; no flow at times in some years.
