LOCATION - Lat 34°07'06", long 117°08'27" referenced to North American Datum of 1927, in NE 1/4 NE 1/4 sec.01, T.1 S., R.3 W., San Bernardino County, CA, Hydrologic Unit 18070203, on left bank, at mouth of canyon, at crossing of North Fork Ditch siphon, and 1.8 mi northeast of East Highlands.
DRAINAGE AREA - 16.9 mi².
REVISIONS HISTORY - WSP 1635: 1924, 1926, 1935-36 (instantaneous maximum discharge), 1943, 1944 (instantaneous maximum discharge), 1945, 1946 (instantaneous maximum discharge), 1947, 1950 (instantaneous maximum discharge). WSP 1715: 1956-58 (instantaneous maximum discharge). WSP 1928: Drainage area.
SURFACE-WATER RECORDS
PERIOD OF RECORD - January 1919 to current year; combined records of creek and diversions, March 1951 to current year.
GAGE - Water-stage recorder and concrete control on creek. Since March 1951, water-stage recorder and weir on upper diversion discontinued Sept. 30, 1991, reactivated July 27, 1993; water-stage recorder and concrete-lined canal on middle diversion; crest-stage gage and sharp-crested weir on lower diversion. The crest-stage gage on the lower diversion was removed in June 2008. Elevation of creek gage is 1,590 ft above NGVD of 1929, from topographic map. Prior to Oct. 1, 1969, creek gage at datum 4.00 ft higher. Diversions all at different datums.
REMARKS - No regulation upstream from station. Diversion from Alder Creek to Upper Plunge Creek area was active 1904-67. Diversions for irrigation are made, at times, at sites 0.5 mi (station 11055450), 1.0 mi (station 11055400), and 2.5 mi (station 11055350) upstream from streamflow station. Diversion stations listed as well as synthetic combination site 11055501 were discontinued in water year 2012. Water has been subject to diversion for irrigation from upstream sites during period of record until end of water year 2012. See schematic diagram of Santa Ana River Basin available from the California Water Science Center.
EXTREMES FOR PERIOD OF RECORD - Creek only: Maximum discharge, 5,740 ft³/s, Dec 22, 2010, on basis of independent high water mark; maximum recorded gage height, 11.29 ft, Dec 22, 2010, from flood marks left by a debris flow near gage. The maximum stage for the period of record is not related to the maximum discharge on that day, but rather it is associated with a debris flow at the gage station. The actual discharge associated with the maximum stage is unknown; no flow at times in some years. Combined creek and diversions: Maximum discharge, 5.740 ft³/s, Dec. 22, 2010; no flow Nov. 12, 1964, Sept. 29, 1965, Aug. 4, 1987, several days in November 1988, September 1991, many days in 1992, and several days in September 2003.
