USGS Water-Year Summary 2021
11452500 Cache Creek at Yolo, CA
LOCATION - Lat 38°43'38", long 121°48'22" referenced to North American Datum of 1927, Yolo County, CA, Hydrologic Unit 18020116, in Rio Jesus Maria Grant, on left bank, 35 ft upstream from Interstate 5 bridge, 0.5 mi south of Yolo, and 7.3 mi downstream from Moore Dam.
DRAINAGE AREA - 1,139 mi².
REVISIONS HISTORY - WSP 1315-A: 1914 (instantaneous maximum discharge). WSP 1345: 1906. WSP 1445: 1955. WSP 1931: Drainage area.
PERIOD OF RECORD - January 1903 to current year. Records for water year 1903 incomplete; yearly estimate published in WSP 1315-A.
GAGE - Water-stage recorder. Datum of gage is 3.14 ft below NAVD of 1988 as determined by GNSS survey in 2019. Datum of gage is subject to change due to subsidence. See WSP 2131 for history of changes prior to Apr. 25, 1969. Apr. 25, 1969, to July 1976, at site 765 ft upstream at same datum.
REMARKS - Some regulation by Clear Lake (station 11450000) beginning in 1915 and Indian Valley Reservoir beginning in 1974. Diversions for irrigation between Capay and Yolo, from data furnished by Clear Lake Water Co. 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, 41,400 ft³/s, Feb. 25, 1958, gage height, 85.35 ft, present datum, maximum stage observed, 86.4 ft, present datum, Mar. 10, 1904; no flow at times in most years.

CHEMICAL DATA: Water years 1958.
SEDIMENT DATA: Water years 1s959-65, 1967, 1986, 2008 to current year (periodic record, storm season only).

WATER TEMPERATURE: Water years January 1959 to May 1965, November 1966 to February 1967 (storm season only)
SUSPENDED-SEDIMENT DISCHARGE: Water years January 1959 to May 1965, November 1966 to February 1967, November 2012 to current year (storm season only).
TURBIDITY: Water years January 17, 2019 to current year (storm season only).

REMARKS - This site is located above the Cache Creek Settling Basin. Due to its proximity to the Basin, it was included in the sediment program for the purpose of comparison of sediment concentrations and sediment loads at the downstream site, Cache Creek at Inflow to Settling Basin (station 11452600).
