USGS Water-Year Summary 2020
11055800 City Creek near Highland, CA
LOCATION - Lat 34°08'38", long 117°11'16" referenced to North American Datum of 1927, in SW 1/4 NW 1/4 sec.27, T.1 N., R.3 W., San Bernardino County, CA, Hydrologic Unit 18070203, on right bank, 0.69 mi upstream from Highland Avenue, and 1.5 mi northeast of Highland.
DRAINAGE AREA - 19.6 mi².
REVISIONS HISTORY - WSP 1635: 1920 (instantaneous maximum discharge), 1923 (instantaneous maximum discharge), 1937 (instantaneous maximum discharge), 1939 (instantaneous maximum discharge), 1946. WSP 1928: Drainage area.
PERIOD OF RECORD - October 1919 to current year; combined records of creek and City Creek Water Co.'s canal, June 1924 to September 1986, October 1988 to current year.
GAGE - Water-stage recorder on creek; water-stage recorder on canal. Elevation of creek gage is 1,580 ft above NGVD of 1929, from topographic map. Prior to Mar. 1, 1939, at site 0.2 mi downstream at different datum. Canal gage at different datum.
REMARKS - No regulation upstream from station. City Creek Water Co.'s canal (station 11055700) diverted from a site 0.5 mi upstream from station for irrigation throughout period of record until Sept. 30, 1986, and resumed diversion on Mar. 31, 1989. Diversion canal damaged by storms of January 1993, with no flow in canal from Jan. 14, 1993, to Apr. 5, 1995. For combined discharge of City Creek and canal see station 11055801. See schematic diagram of Santa Ana River Basin available from the California Water Science Center.
EXTREMES FOR PERIOD OF RECORD - Creek only: Maximum discharge, 9,900 ft³/s, Jan. 10, 2005, gage height, 10.68 ft, on basis of slope-area measurement of peak flow, at site 0.50 mi downstream; maximum gage height, 11.06 ft, Dec. 25, 2003, from floodmark left by a debris flow near the gage; no flow for many days in some years. The maximum stage for the period of record is not related to the maximum discharge on that day, but rather is associated with a debris flow at the gaging station. The stage associated with the maximum discharge on Dec. 25, 2003, is unknown. The maximum discharge on Dec. 25, 2003, (8,000 ft³/s) is based on hydraulic computations that were applied to a possible hyper-concentrated flow event. The peak flow was the result of an intense rain storm that occurred less than two months after a wildfire burned over 90 percent of the drainage basin. Combined creek and canal: Maximum discharge, 9,900 ft³/s, Jan. 10, 2005; no flow at times in some years.
