SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1912 to current year.
GAGE - Non recording gage. Elevation of gage datum is arbitrary. Supplemental recording gage from May 17 to June 2, 1984.
REMARKS - Reservoir is formed by earthen dam constructed in 1911-13; storage began in 1911. Usable capacity, 77,400 acre-ft between gage heights 0.0 ft, bottom of diversion tunnel, and 138.4 ft, crest of spillway. Silt deposition at the dam has decreased storage capacity, affecting the reliability of the capacity table particularly at the lower elevations. Crest raised in May 1984 from 136.0 ft. Dead storage negligible. Water is used for irrigation of lands along Goose Creek in Oakley Canal Co. project. Figures given herein represent usable contents. Reservoir is known locally as Lower Goose Creek Reservoir.
EXTREMES FOR PERIOD OF RECORD - Maximum contents observed, 75,600 acre-ft May 22, 1984, gage height, 137.0 ft; reservoir drained at close of irrigation season in 1915, 1919-20, 1926, 1933, 1950, 1959, 1987.
