SURFACE-WATER RECORDS

PERIOD OF RECORD - Jan. 1952 to Sept. 2000 (U.S. Army Corps of Engineers furnished contents), Oct. 2000 to Sept. 2002 (contents), Oct. 2002 to current year. Prior to Oct. 1970, published as "Whitney Reservoir". Oct. 1979 to Sept. 2004, published as "Lake Whitney". PERIOD OF RECORD, Water-Quality.-- CHEMICAL DATA: Jan. 1975 to Sept. 1977. BIOCHEMICAL DATA: Jan. 1975 to Sept. 1977.

GAGE - Water-stage recorder. Datum of gage is 0.00 ft above NGVD of 1929 (levels by U.S. Army Corps of Engineers) and 0.16 ft below NAVD of 1988. To obtain elevations in NAVD 1988, add 0.16 ft. Satellite telemeter at station.

REMARKS - Some records listed in the "Period of Record" for surface water and water quality may not be available electronically. The lake is formed by a concrete-gravity and rolled earthfill dam 17,695 ft long, including spillway. The dam was completed in Apr. 1951, and deliberate impoundment began Dec. 10, 1951. Concrete spillway is 680 ft long and includes 17 tainter gates 38 by 40 ft each. Outlet works are comprised of 16 gate-operated conduits that are 5 by 9 ft each. The space between elevations 522.0 and 571.0 ft is reserved for flood-control storage. At maximum design elevation of 573.0 ft the spillway is designed to discharge 684,000 ft³/s. Data regarding the dam are given in the following table:

                                                                              Elevation (feet)
Top of dam............................................................          584.0
Design flood..........................................................          573.0
Top of gates..........................................................          571.0
Crest of spillway (sill of gates).....................................          533.0
Top of conservation pool (top of designated power storage)............          533.0
Lowest controlled outlet (invert).....................................          448.8
