USGS Water-Year Summary 2021
LOCATION - Lat 34°33'19", long 111°11'00" referenced to North American Datum of 1927, in NE 1/4 SE 1/4 sec.33, T.14 N., R.11 E., Coconino County, AZ, Hydrologic Unit 15020008, in Coconino National Forest, on upstream side of left end of spillway structure of Blue Ridge Dam on East Clear Creek, at mouth of General Springs Canyon, 7.3 mi east of Clints Well, and 20 mi northeast of Pine.
DRAINAGE AREA - 71.1 mi².
PERIOD OF RECORD - Dec. 1964 to Mar. 1965 (periodic elevations only), Apr. 1965 to current year.
GAGE - Water-stage recorder. Datum of gage is 6,620 ft above sea level; gage readings have been reduced to elevations NGVD. Prior to Apr. 2, 1965, nonrecording-gage, readings (at intervals of 3 to 8 days) at NGVD.
REMARKS - Records good except for estimated gage height and reservoir storage, which are poor. Reservoir is formed by a concrete arch dam. Dam completed and storage began in Dec. 1964. Total capacity is 19,500 acre-ft at elevation 6,735 ft, of which 15,000 acre-ft is usable storage below 6,720 ft, the spillway crest. Drawdown below 6,646.3 ft, 2,620 acre-ft restricted by sill at mouth of diversion tunnel since Nov. 1981. Reservoir serves as a basin from which water is pumped to the East Verde River. (See records for East Verde River diversion from East Clear Creek, near Pine.) Release is possible through valve in base of dam. Figures given herein represent total contents.
EXTREMES FOR PERIOD OF RECORD - Maximum contents, 17,360 acre-ft, Dec. 29, 2004; elevation, 6,728.01 ft; minimum contents since reservoir filled (Apr. 1965), 1,450 acre-ft, Nov. 18-27, 1981; minimum elevation, 6,630.75 ft, Nov. 26, 1981.
