USGS Water-Year Summary 2020
11453000 Yolo Bypass near Woodland, CA
LOCATION - Lat 38°40'40", long 121°38'35" referenced to North American Datum of 1927, Yolo County, CA, Hydrologic Unit 18020163, unsurveyed, on left bank, 300 ft upstream from Sacramento and Woodland Railroad Bridge, 6 mi upstream from Sacramento Bypass, 6 mi downstream from Fremont Weir, and 7 mi east of Woodland.
DRAINAGE AREA - Drainage area below gage 11452500, Cache Creek at Yolo, CA, is indeterminate.
REVISIONS HISTORY - WDR CA-96-4: 1995 (instantaneous maximum discharge).
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1939 to current year (since October 1977, high flows only). Monthly discharge only for some periods, published in WSP 1315-A.
GAGE - Water-stage recorder. Datum of gage is 3.41 ft below NGVD of 1929. Prior to Dec. 17, 1941, nonrecording gage, and Dec. 18-31, 1941, water-stage recorder, at datum 0.73 ft higher. Prior to Sept. 30, 1977, a supplementary water-stage recorder 6 mi downstream at different datum recorded low flow.
REMARKS - Records prior to 2015 not computed below 1,000 ft³/s. Flow is from Cache Creek and Knights Landing Ridge Cut plus floodwater passing over Fremont Weir. Published discharges reflect rated flows at this site minus the flows released at the Sacramento Weir Spill to Yolo Bypass, near Woodland (station 11426000), when it is in operation, which are provided by California Department of Water Resources. Beginning October 1977 through September 2014, only flows above 1,000 ft³/s were computed. See schematic diagrams of lower Sacramento River Basin and Sacramento-San Joaquin Delta available from the California Water Science Center.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 374,000 ft³/s, Feb. 20, 1986, gage height, 34.87 ft; no flow at times in several years.
