Construction

The lake construction was paid for by the sale of revenue bonds that were to be redeemed with income derived from the sale of water. The dam construction began in 1966 and was completed in 1969, by Forrest and Cotton, Incorporated. The cost to build the earthen dam was US$83,996,957 ($603,985,378 in 2021 dollars).

Use

Water stored in the lake is used to supply industrial, municipal, and agricultural needs in the lower Trinity River Basin and the Houston/Galveston metropolitan area. Its significance in the face of the extraordinary growth experienced by this region of the upper Texas Gulf Coast is tremendous. Many public and commercial recreation facilities, including full-service marinas, camping, and motel accommodations are located along the shoreline. The City of Houston owns two-thirds of the water rights of the lake, with the other third remaining under the control of the TRA.
