USGS Water-Year Summary 2023
11367760 McCloud River below McCloud Dam, near McCloud, CA
LOCATION - Lat 41°07'31", long 122°04'03" referenced to North American Datum of 1927, in SW 1/4 NE 1/4 sec.27, T.38 N., R.2 W., Shasta County, CA, Hydrologic Unit 18020004, Shasta National Forest, on left bank, 0.1 mi downstream from Lizard Creek, 0.6 mi downstream from McCloud Dam, and 9 mi southeast of McCloud.
DRAINAGE AREA - 404 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD - April 1966 to current year (operated as a low-flow station only).
GAGE - Water-stage recorder. Datum of gage is 2,398.76 ft above NGVD of 1929 (levels by Pacific Gas and Electric Co.). Prior to Apr. 7, 1972, at datum 3.00 ft higher.
COOPERATION - Records were collected by Pacific Gas and Electric Co., under general supervision of the U.S. Geological Survey, in connection with Federal Energy Regulatory Commission project no. 2106.
REMARKS - Low flow regulated by Lake McCloud (station 11367740) since November 1965. Most of McCloud River runoff is diverted from reservoir through tunnel to Iron Canyon Reservoir (station 11363920) in Pit River Basin. This station records fishwater release. The minimum release requirement is 40 ft³/s at all times. Prior to water year 1974, flow was computed up to 400 ft³/s. During water years 1975-81, because of channel changes, flow was computed up to 200 ft³/s. From 1982-2009, flow was computed up to 220 ft³/s. Beginning 2010, because of maximum required release, flow is computed to 300 ft³/s. See schematic diagram of Pit River and McCloud River Basins available from the California Water Science Center.
