USGS Water-Year Summary 2021
11255575 Panoche Creek at Interstate 5, near Silver Creek, CA
LOCATION - Lat 36°39'09", long 120°37'52" referenced to North American Datum of 1927, in NE 1/4 SW 1/4 sec.02, T.15 S., R.12 E., Fresno County, CA, Hydrologic Unit 18040014, on left bank, at downstream side of Interstate Highway 5 bridge over Panoche Creek, 7.3 mi southwest of Silver Creek Township, and 11.8 mi east of Panoche.
DRAINAGE AREA - 305 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD - December 1997 to current year (seasonal records only, Dec. 1 to June 30). Peak discharges determined for entire year. CHEMICAL DATA: Water years 1998-2006, 2008 (seasonal records only). SEDIMENT DATA: Water years 1998-2008 (seasonal records only).
GAGE - Water-stage recorder. Datum of gage is 450 ft above NGVD of 1929, from topographic map.
REMARKS - No flow for period of seasonal record in 2014-2015 water years, no flow most days in 2016-2018 water years. No known regulation or diversions upstream of station. A gravel operation located about 1 mi upstream of gage excavates the dry stream bed each season. This creates the potential for entrapping an unknown volume of water and sediment before it reaches the gage location. Irrigation return flow enters the stream channel from time to time in some years.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 9,940 ft³/s, Feb. 3, 1998, gage height, 13.46 ft, from rating curve extended above 1,500 ft³/s, on the basis of slope-area measurement of peak flow; no flow for many days each year.
WATER-QUALITY RECORDS
PERIOD OF RECORD - Water year 1998 to June 2008 (discontinued). CHEMICAL DATA: Water years 1998 to 2006, February 2008 (seasonal records only) (discontinued). SEDIMENT DATA: Water year 1998 to June 2008 (seasonal records only) (discontinued).
