DRAINAGE AREA - 45.4 mi².
REVISIONS HISTORY - WSP 1930: 1953. WDR CA-89-3: Drainage area, 1987 (instantaneous maximum discharge), 1988 (instantaneous maximum discharge), WRD US-2009: 2005.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1952 to current year.
GAGE - Acoustic-flow meter at New Spicer Meadow Powerplant (station 11293760) and water-stage recorder on New Spicer Meadow Reservoir (station 11293770). Elevation of gage is 6,340 ft above NGVD of 1929, from topographic map. October 1952 to November 1986, at site 900 ft upstream at different datum. December 1986 to September 1990 at site 1,400 ft downstream at different datum.
COOPERATION - Records were collected by Northern California Power Agency, under general supervision of the U.S. Geological Survey, in connection with Federal Energy Regulatory Commission project no. 2409.
REMARKS - Low and medium flows regulated by New Spicer Meadow Reservoir since 1988 and, prior to 1988, by Spicer Meadows Reservoir, capacity, 4,060 acre-ft. Flow has been diverted to New Spicer Meadow Reservoir from North Fork Stanislaus River since Oct. 21, 1987. Penstock diverts from New Spicer Meadow Reservoir to New Spicer Meadow Powerplant. At times flow may bypass New Spicer Meadow Powerplant. Discharges, including extremes, represent flow through powerplant and flow over spillway of reservoir. See schematic diagram of Stanislaus River Basin available from the California Water Science Center.
EXTREMES OUTSIDE PERIOD OF RECORD - Flood of Nov. 20, 1950, reached a stage of 11.50 ft, site and datum then in use, from Pacific Gas and Electric Co. recorder chart, discharge, 8,800 ft³/s.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 9,860 ft³/s, Jan. 31, 1963, gage height, 11.88 ft, site and datum then in use, from rating curve extended above 1,200 ft³/s; no flow some years.
