The State of Texas owns all surface water in the state and the Texas Commission on Environmental Quality is the agency responsible for regulating (permitting) the use of this surface water. The TCEQ issues the water rights for reservoirs in Texas. The water rights issued to the Brazos River Authority grant the ability to store and use water for beneficial purposes, including the sale of water for municipal, steam-electric cooling and other uses. BRA owns the water right for Lake Granbury (and 11 other lakes) and provides water to our customers by contract under the terms of that water right.
