SURFACE-WATER RECORDS
PERIOD OF RECORD - Aug. 1945 to current year.
PERIOD OF RECORD, Water-Quality.--
CHEMICAL DATA: June 1978 to Sept. 1981.
BIOCHEMICAL DATA: June 1978 to Sept. 1981.
GAGE - Water-stage recorder. Datum of gage is NAVD 1988, 2001 adjustment. Prior to Oct. 1, 2008, datum of gage was NGVD of 1929, 1973 adjustment; unadjusted for land-surface subsidence since 1973 (2.31 ft above current datum). Prior to Oct. 1, 1980, datum of gage was 0.33 ft below NGVD of 1929, unadjusted for land-surface subsidence (1.98 ft above current datum). Satellite telemeter at station.
COOPERATION - The capacity table, furnished by the U.S. Army Corps of Engineers, is based on extensive releveling survey made in 2001 using NAVD of 1988, 2001 adjustment as base.
REMARKS - Some records listed in the "Period of Record" for surface water and water quality may not be available electronically. The reservoir is formed by a rolled earthfill dam 71,900 ft long. The dam was completed Feb. 3, 1946, but was used as early as the spring of 1945 for flood control. The reservoir is operated for flood protection for the city of Houston. The controlled outlet works consist of five concrete conduits, 9 x 7 ft wide, each controlled by a vertical slide gate. Data regarding the dam are given in the following table:
