1998 California Hydrologic Data Report
10256500 SNOW CREEK NEAR WHITE WATER, CA
- 1998 WY
10256500 SNOW CREEK NEAR WHITE WATER, CA
LOCATION.-Lat 33°52'14", long 116°40'49", in NW 1/4 NW 1/4 sec.33, T.3 S., R.3 E., Riverside County, Hydrologic Unit 18100200, on left bank at upstream side of Desert Water Agency Diversion Dam, 0.1 mi downstream from East Fork, and 4.4 mi southwest of White Water.
DRAINAGE AREA.-10.9 mi2.
WATER-DISCHARGE RECORDS
PERIOD OF RECORD.-July to December 1921, May 1922 to February 1927, December 1927 to September 1931, October 1959 to current year. Yearly discharges for 1929-31, published in WSP 1314. Discharge records for Snow Creek Diversion (station 10256550) since October 1978, and those for creek only October 1978 through September 1988 available in files of the U.S. Geological Survey.
REVISED RECORDS.-WDR CA-89-1: Drainage area. WDR CA-90-1: 1980 Combined discharge. WDR CA-93-1: 1991. WDR CA-96-1: 1969(M), 1976(M).
GAGE.-Water-stage recorder, crest-stage gage, and broad-crested weir on creek, non-recording flow meter on diversion. Elevation of gage is 2,000 ft above sea level, from topographic map. Prior to October 1931, at various sites within 500 ft of present site at different datums. October 1959 to Oct. 6, 1970, at site 40 ft upstream at present datum. Oct. 6, 1970, to Oct. 25, 1978, at site 290 ft upstream from diversion at present datum. Gage moved to present site 10 ft downstream from diversion Oct. 25, 1978.
REMARKS.-Records fair except for estimated daily discharges, which are poor. No regulation upstream from station. Diversion (station 10256550) 10 ft upstream, generally taking most of the base flow. For combined record of creek and diversion, see station 10256501. Published record prior to 1989 represents entire flow from basin (combined creek plus diversion prior to March 1927 and October 1978 to September 1988; creek only, upstream from diversion, December 1927 to September 1931, and October 1959 to September 1978). Both creek only and combined flow published beginning October 1989. Statistics for station 10256501 (combined flow) reflect equivalent total flow from basin. See schematic diagram of Salton Sea Basin.
COOPERATION.-Records for diversion provided by Desert Water Agency.
EXTREMES FOR PERIOD OF RECORD (Combined creek and diversion).- Maximum discharge, 9,900 ft3/s, Jan. 25, 1969, gage height, 13.8 ft, from floodmarks, site and datum then in use, from rating curve extended above 55 ft3/s on basis of slope-area measurement of peak flow; minimum daily, 2.1 ft3/s, June 23-27, Sept. 5-11, 1961.
EXTREMES FOR CURRENT YEAR.-Peak discharges greater than base discharge of 100 ft3/s, or maximum, from rating curve extended above 29.9 ft3/s on basis of broad-crested weir computations:
