Usable capacity, 64,250 acre-ft between gage height 4,729.3 ft, 9.3 ft above lowest outlet gage sill, and 4,788.00 ft (spillway crest). Streambed above gates prevents withdrawal of storage to sill elevation. Dead storage is 1,900 acre-ft below gage height 4,729.30 ft. Figures given herein represent usable contents.
