GAGE.--Water-stage recorder. Datum of gage is NGVD of 1929 (Levels by U.S. Army Corps of Engineers). To convert elevations to NAVD of 1988, subtract 0.55 ft. Prior to Apr. 8, 1952, nonrecording gage at same site and datum.
COOPERATION.--Capacity table provided by U.S. Army Corps of Engineers, 1953.
REMARKS.--Lake is formed by a concrete gravity-type dam with overflow spillway, completed by U.S. Army Corps of Engineers in 1951 for flood control; first used for flood regulation on Nov. 24, 1951. Usable capacity, 336,800 acre-ft between elevation 585.0 ft, sill of conduits, and 760.0 ft, crest of spillway. Dead storage, 609 acre-ft. Figures given herein represent total contents. Discharge is controlled by the operation of nine gates. Water is stored during high flows and released when downstream conditions warrant.
