USGS Water-Year Summary 2025
11441900 Silver Creek below Camino Diversion Dam, CA
LOCATION - Lat 38°49'26", long 120°32'18" referenced to North American Datum of 1927, in sec.05, T.11 N., R.13 E., El Dorado County, CA, Hydrologic Unit 18020129, in Eldorado National Forest, on right bank, 300 ft downstream from Round Tent Canyon, 0.4 mi downstream from diversion dam, and 5 mi northeast of Pollock Pines.
DRAINAGE AREA - 171 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1960 to current year.
GAGE - Water-stage recorder. Datum of gage is 2,754.06 ft above NGVD of 1929 (Sacramento Municipal Utility District benchmark).
COOPERATION - Records were collected by Sacramento Municipal Utility District, under general supervision of the U.S. Geological Survey, in connection with Federal Energy Regulatory Commission project no. 2101.
REMARKS - Flow is regulated by Ice House Reservoir (station 11441100) since 1959, Union Valley Reservoir (station 11441001) since 1962, and Junction and Camino Reservoirs (stations 11441760 and 11441890). Diversion to Camino Powerplant since 1961 bypasses this station. See schematic diagram of South Fork American River Basin available from the California Water Science Center.
