SURFACE-WATER RECORDS

PERIOD OF RECORD - Apr. 1954 to current year. PERIOD OF RECORD, Water-Quality.-- CHEMICAL DATA: July 1961 to Apr. 1964, Dec. 1969 to Sept. 2004. BIOCHEMICAL DATA: Aug. 1983 to Sept. 2004. PESTICIDE DATA: May 1968 to Aug. 1972, Aug. 1983 to Sept. 2004. SEDIMENT DATA: Feb. 2000 to Sept. 2004.

GAGE - Water-stage recorder. Datum of gage at dam is NAVD 1988, 2001 adjustment. Prior to Oct. 1, 2009, datum of gage at dam was 0.70 ft below NGVD of 1929; unadjusted for land-surface subsidence (2.77 ft below current datum). Satellite telemeter at station.

COOPERATION - The capacity table is based on a bathymetric survey made in 1994 by Texas Water Development Board. Records of diversions may be obtained from the San Jacinto River Authority and the city of Houston.

REMARKS - The lake is formed by two earthfill embankment sections and a 3,160-foot long concrete spillway midway between the embankment sections. The dam was completed and storage began Apr. 9, 1954. The spillway includes two tainter gates, 18.0 x 20.5 ft, that can be used for control of releases below gage heights of 41.7 ft and above 25.2 ft. In addition, there is a 36-inch-diameter sluice gate that is used for low-flow releases. The dam is owned by the city of Houston. Water is used for irrigation, municipal, and industrial supply in the Houston metropolitan area. Data regarding the dam are given in the following table:
