Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.

10259300 Whitewater River at Indio, CA
LOCATION - Lat 33°44'14", long 116°14'07" referenced to North American Datum of 1927, in SE 1/4 NE 1/4 sec.15, T.5 S., R.7 E., Riverside County, CA, Hydrologic Unit 18100201, on right bank of concrete drop structure, 1,000 ft upstream from Monroe Street Bridge, and 1.7 mi northwest of Indio.
DRAINAGE AREA - 1,073 mi².
REVISIONS HISTORY - WDR CA-72-1: 1971.
SURFACE-WATER RECORDS
PERIOD OF RECORD - March 1966 to current year.
GAGE - Water-stage recorder and crest-stage gage. Concrete control since Oct. 1, 1979. Datum of gage is 18.23 ft below NAVD of 1988. Prior to Oct. 1, 1979, water-stage recorder at site 0.5 mi upstream at different datum. Oct. 1, 1979, to Feb. 17, 1983, and Feb. 18, 1983, to Nov. 18, 1991, at same site at different datums.
REMARKS - No regulation upstream from station. Water diverted from tributary streams for municipal supply in vicinity of Palm Springs.

EXTREMES OUTSIDE PERIOD OF RECORD - Flood of Mar. 2 or 3, 1938, reached a discharge of 29,000 ft³/s, on basis of slope-area measurement, at site 5.0 mi upstream. Flood of Nov. 22, 1965, reached a stage of 15.3 ft, from floodmark, at site and datum used prior to Oct. 1, 1979, discharge, 14,100 ft³/s, on basis of slope-area measurement of peak flow.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 16,500 ft³/s, Feb. 14, 2019, gage height, 12.96 ft, from slope area computation; no flow for all or most of each year.
