SURFACE-WATER RECORDS

PERIOD OF RECORD - Jan. 1963 to Sept. 2000 (contents furnished by U.S. Army Corps of Engineers), Oct. 2000 to Sept. 2002 (contents), Oct. 2002 to current year. Prior to Oct. 1970, published as "Proctor Reservoir". PERIOD OF RECORD, Water-Quality.-- CHEMICAL DATA: Jan. 1964 to July 1982, Jan. 1990 to Aug. 1997. BIOCHEMICAL DATA: Jan. 1964 to July 1982, Jan. 1990 to Aug. 1997.

GAGE - Water-stage recorder. Datum of gage is U.S. Army Corps of Engineers local datum. To compute lake elevation in NAVD88 subtract 0.05 ft. Prior to May 28, 1963, nonrecording gage at same site and datum. Satellite telemeter at station.

COOPERATION - U.S. Army Corps of Engineers - Fort Worth District, USACE.

REMARKS - Intermittent missing record is the result of editing erroneous values. Some records listed in the period of record may not be available electronically. The lake is formed by a reinforced concrete gated structure and rolled earthfill dam, total length 13,460 ft. The lake was operated as a detention basin from Jan. 30 to July 5, 1963. The gates were closed July 6, 1963, but the lake was operated as a detention basin to elevation 1,156.0 ft. until construction was completed. Deliberate impoundment began Sept. 30, 1963. The spillway is a gated concrete gravity structure located on the left bank, with an ogee weir section and basin. The spillway is controlled by eleven 40.0- by 35.0-foot tainter gates. The spillway was designed to discharge 431,800 ft³/s at an elevation of 1,201.0 ft. The lake is operated for flood control and water conservation. Inflow is partly regulated by Leon Reservoir (station 08099000, conservation pool storage 26,420 acre-ft.). Inflow is also affected at times by discharge from the flood-detention pools of 23 floodwater-retarding structures with a combined detention capacity of 43,690 acre-ft. These structures control runoff from 172 mi² in the Leon River and Rush Creek drainage basins. Borrow is not included in capacity totals. The dam is owned by the U.S. Army Corps of Engineers. Conservation pool storage is 55,590 acre-ft. Records of diversions may be obtained from the U.S. Army Corps of Engineers. Data regarding the dam are given in the following table. The USGS is not responsible for errors in datum or elevations provided by other entities.
