USGS Water-Year Summary 2023
11361450 Pit River below Lake Britton Dam, near Burney, CA
LOCATION - Lat 41°01'18", long 121°40'25" referenced to North American Datum of 1927, in NW 1/4 NW 1/4 sec.30, T.37 N., R.3 E., Shasta County, CA, Hydrologic Unit 18020003, Shasta National Forest, in tunnel through dam, 1.7 mi downstream from Clark Creek, 1.4 mi northwest of Burney Falls, and 9.6 mi north of Burney.
DRAINAGE AREA - 4,607 mi², excluding Goose Lake Basin.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 2012 to current year.
GAGE - Acoustic-velocity meter measures bypass flow; water-stage recorder and concrete control for spillway. Datum of gage is 19.53 ft below NGVD of 1929 (levels by Pacific Gas and Electric Co.).
COOPERATION - Record of contents collected by Pacific Gas and Electric Co., under general supervision of the U.S. Geological Survey, in connection with a Federal Energy Regulatory Commission project no. 233.
REMARKS - Two components combine for total published flow at this station. The primary component is flow through a 96" diameter pipe that is gauged by an AVM with a maximum operational flow of 550 ft³/s. Discharge exceeding that amount, either immediately or forecast, is allowed to spill over the top of a rated spillway. The spillway is equipped with rubber bladders which allow for increased storage when they are inflated during the summer season but because they are not designed to have water spill over them, they are kept deflated during the winter operating season or whenever a reasonable possibility of spill exists.
