1998 California Hydrologic Data Report
10257500 FALLS CREEK NEAR WHITE WATER, CA
- 1998 WY
10257500 FALLS CREEK NEAR WHITE WATER, CA
LOCATION.-Lat 33°52'10", long 116°40'15", in SW 1/4 NE 1/4 sec.33, T.3 S., R.3 E., Riverside County, Hydrologic Unit 18100200, on right bank at upstream side of Desert Water Agency Diversion Dam, 0.75 mi upstream from confluence with Snow Creek, and 4.4 mi southwest of White Water.
DRAINAGE AREA.-4.14 mi2.
PERIOD OF RECORD.-September 1922 to January 1927, January 1928 to July 1931, and October 1994 to current year. Previous gage destroyed by flood of Aug. 29, 1931. Monthly and yearly discharges for 1922-31, published in WSP 1314. Discharge records for Falls Creek Diversion (station 10257499) since October 1994 available in files of the U.S. Geological Survey.
GAGE.-Water-stage recorder, broad-crested weir, and crest-stage gage on creek, non-recording flow meter on diversion. Auxiliary gage 0.25 mi downstream with crest-stage gage and culvert control. Elevation of gage is 1,940 ft above sea level, from topographic map.
REMARKS.-Records fair except for estimated daily discharges, which are poor. No regulation upstream from station. Diversion (station 10257499) immediately upstream takes a varying portion of the base flow. For combined record of creek and diversion, see station 10257501. Published record prior to 1995 represents entire flow from basin. Records for the period 1922-1931 (prior to construction of diversion) are equivalent to those for station 10257501. Both creek only and combined flow published beginning October 1994. Statistics for station 10257501 (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, 154 ft3/s, Jan. 10, 1995, gage height, 6.14 ft (creek gage; no diversion at peak), from rating curve extended above 6.5 ft3/s on basis of critical depth computations; maximum gage height, 6.24 ft, Feb. 14, 1998; minimum daily, 0.10 ft3/s, Sept. 11, 1997.
EXTREMES FOR CURRENT YEAR.-Peak discharges greater than base discharge of 50 ft3/s, or maximum, from rating curve extended as noted above:
