DRAINAGE AREA - 108 mi².
REVISIONS HISTORY - WDR UT-77-1: 1975.
SURFACE-WATER RECORDS
PERIOD OF RECORD - December 1937 to current year.
GAGE - Transducer and data logger gage records lake elevation hourly and transmits via SCADA system hourly. Datum of gage is 8064.16 ft above sea level (levels by Bureau of Reclamation).
COOPERATION - Capacity table provided by Bureau of Reclamation. Reservoir elevations furnished by Moon Lake Water Users Association.
REMARKS - Reservoir formed by a zoned earthfill, rockfaced dam with concrete core. Storage began December 9, 1937. Active capacity, 37,800 acre-ft between elevations 8,072 ft, crest of original outlet of lake, about 2,000 ft upstream from dam, and 8,137 ft. Figures given herein represent usable contents. Water is used for irrigation on lands under Moon Lake Water Users Association and Uintah Indian Irrigation projects. A new active capacity table was put into use at the beginning of the 2013 water year. A small portion of active capacity (56 AF) lies below the documented dead storage elevation of 8,072 ft. This pool is isolated from the dead storage pool by a land feature that peaks at 8,072 ft. Although the intake for the outlet works is at 8,066 ft, the land feature results in an effective dead storage elevation of 8,072 ft.
EXTREMES FOR PERIOD OF RECORD - Maximum contents observed, 38,548 acre-ft, June 18-23, 2017; elevation, 8,137.9 ft; minimum usable storage, 0.0 acre-ft, Sep 18-30, 2007.
