De Cordova Bend Dam and Lake Granbury were constructed by the Brazos River Authority and are maintained and operated by the Authority as a source of water supply.

Construction of the project began in December 1966 and was completed in September 1969. The project provides 129,011 acre-feet of storage capacity for conservation of flood and storm waters to meet requirements of municipalities, industries, agriculture and mining.  To view the state permit establishing Lake Granbury, click here

The lake was built without use of any tax money, having been financed entirely with revenues from sales of water by the Authority. The principal revenues used to finance the project are provided under a contract with TXU Electric Company for purchase of water for industrial use, including cooling water for a natural gas-fired steam electric power plant on the lake and the Comanche Peak nuclear power plant near Glen Rose. The lake also furnishes raw water for the Authority’s Lake Granbury Surface Water and Treatment System, which supplies treated water to customers in Hood and Johnson counties. 

The lake has five public access areas for picnicking and fishing. Four of these areas have primitive camping sites.
