DRAINAGE AREA - 4,042 mi².
REVISIONS HISTORY - WDR CA-85-2: 1983-84 (instantaneous maximum discharge).
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1976 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 70.54 ft above NAVD of 1988. Prior to January 1979, nonrecording gage at same site and datum. January 1979 to Aug. 19, 1991, at site 0.2 mi downstream at same datum.
REMARKS - Daily discharges prior to January 1979 determined by discharge measurements at this site correlated to streamflow for "Salinas River at Soledad" (station 11151700) and "Salinas River near Spreckels" (station 11152500). Flow regulated by Santa Margarita Lake beginning in December 1941, usable capacity, 23,000 acre-ft; Lake Nacimiento (formerly Nacimiento Reservoir) beginning in February 1957, usable capacity, 340,000 acre-ft; and Lake San Antonio beginning in December 1965, usable capacity, 330,000 acre-ft. Large withdrawals from ground water and small surface-water diversions for municipal use and for irrigation upstream from station. See schematic diagram of Salinas River Basin available from the California Water Science Center.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 92,000 ft³/s, estimated, Mar. 11, 1995, gage height, 19.70 ft, from rating curve extended above 18,000 ft³/s; peak flow includes an estimate of 8,800 ft³/s bypassing the gage; no flow at times during most years.
