USGS Water-Year Summary 2019
10260500 Deep Creek near Hesperia, CA
LOCATION - Lat 34°20'35", long 117°13'32" referenced to North American Datum of 1927, in NE 1/4 SE 1/4 sec.18, T.3 N., R.3 W., San Bernardino County, CA, Hydrologic Unit 18090208, on right bank, 0.5 mi upstream from confluence with West Fork Mojave River at Mojave River Forks Dam, 7 mi southeast of Hesperia, and 11 mi downstream from Lake Arrowhead.
DRAINAGE AREA - 134 mi².
REVISIONS HISTORY - WSP 1314: 1931 (instantaneous maximum discharge). WSP 1927: Drainage area.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1904 to September 1922, October 1929 to current year. Prior to January 1930, monthly discharges only, published in WSP 1314.
GAGE - Water-stage recorder. Broad-crested weir since December 1938. Elevation of gage is 3,030 ft above NGVD of 1929, from topographic map. See WSP 1314 for history of changes prior to Dec. 10, 1938.
REMARKS - Slight regulation by Lake Arrowhead, capacity, 48,000 acre-ft, principally used for recreation. Sewage effluent from Lake Arrowhead area is released above gage at times. See schematic diagram of Mojave River Basin available from the California Water Science Center.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 46,600 ft³/s, Mar. 2, 1938, gage height unknown, on basis of slope-area measurement of peak flow; maximum gage height, 33.30 ft, Jan. 11, 2005 (backwater from Mojave River Forks Reservoir); no flow July 17, 18, 1961.
WATER-QUALITY RECORDS
PERIOD OF RECORD - Water year 2007 to current year. CHEMICAL DATA: Water year 2007 to current year.
PERIOD OF DAILY RECORD - pH: December 2006 to current year. SPECIFIC CONDUCTANCE: December 2006 to current year. WATER TEMPERATURE: December 2006 to current year.
INSTRUMENTATION - Water-quality monitor recording pH, specific conductance, and water temperature since November 2006. Upgraded to real-time data collection, February 2013.
REMARKS - Interruptions in the record due to impact from swimmer dams during the summer months. pH records rated good for the 2016 WY. Specific Conductance records rated good for the 2016 WY. Water temperature records rated excellent for the 2016 WY. NOTE The practice of describing qualitative water-quality time-series record accuracy was discontinued in 2017.
