USGS Water-Year Summary 2023

11202710 Middle Fork Tule River below Intake, above Springville, CA

LOCATION - Lat 36°09'41", long 118°42'31" referenced to North American Datum of 1927, Tulare County, CA, Hydrologic Unit 18030006, unsurveyed, in Sequoia National Forest, on right bank, 700 ft downstream from confluence of North Fork Middle Fork Tule River and South Fork Middle Fork Tule River, and 6.5 mi northeast of Springville.

DRAINAGE AREA - 85.3 mi².

REVISIONS HISTORY - WDR CA-95-3: 1993 (instantaneous maximum discharge).

SURFACE-WATER RECORDS

PERIOD OF RECORD - October 1988 to September 1990, October 1991 to current year. Prior to October 2002, published as river only, and river and conduit combined.

GAGE - Water-stage recorder and V-notch sharp-crested weir in concrete control. Elevation of gage is 2,370 ft above NGVD of 1929, from topographic map.

COOPERATION - Records collected by Southern California Edison Co., under general supervision of the U.S. Geological Survey, in connection with Federal Energy Regulatory Commission project no. 372.

REMARKS - Southern California Edison Co.'s Tule River Conduit diverts from the right bank of Middle Fork Tule River upstream from station. Flow from this conduit passes through Tule River Powerplant of Southern California Edison Co. Diversions are made at powerplant to Springville Diversion and Duncan Diversion Ditches. Remaining water is returned to the Tule River 1.5 mi upstream from confluence of Middle and North Forks. The record of combined discharges of river and conduit was discontinued September 2002 when the conduit gage location was moved from near the point of diversion (station 11202700) to near the powerplant (station 11202838). The conduit-flow records from those two locations may not be equivalent due to gains or losses along the conduit. See schematic diagram of Tule River Basin available from the California Water Science Center.

EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 19,400 ft³/s, Jan. 2, 1997, gage height, 11.82 ft; minimum daily, 4.8 ft³/s, Oct. 3, 1996.
