HB 4530 amends sections of the Parks and Wildlife Code and the Water Code to improve the functionality of the Texas Water Trust—a program established to hold water rights for environmental purposes. The bill directs the Texas Parks and Wildlife Department (TPWD) to proactively encourage the voluntary dedication of surface water rights to the trust through mechanisms such as lease, donation, or purchase. These dedications are aimed at supporting ecological benefits, including maintaining instream flows, improving water quality, supporting fish and wildlife habitats, and securing freshwater inflows to bays and estuaries.
The bill also clarifies TPWD’s authority to manage surface water rights held in the trust. It ensures that the department’s management practices align with the terms of the dedication and relevant sections of the Water Code. These include provisions dealing with water rights amendments, the reuse of water, and maintenance of beneficial uses. The agency is instructed to manage these water rights in a way that maximizes environmental benefits while remaining consistent with how the original right holders could have used the water.
In a significant expansion of the Water Trust's scope, HB 4530 authorizes the dedication of groundwater rights—something not previously outlined in statute. It establishes that such dedications must be reviewed and approved by the Texas Water Development Board (TWDB). Additionally, it requires the TWDB to provide notice of groundwater dedications to local groundwater conservation districts or authorities with jurisdiction over the relevant aquifer or geologic stratum. This provision enhances local transparency and safeguards the role of local groundwater management entities.
The bill takes effect on September 1, 2025. Overall, HB 4530 is intended to strengthen voluntary conservation efforts in Texas by streamlining the process for dedicating both surface and groundwater rights to the Texas Water Trust, increasing cooperation among state agencies, and ensuring environmental and ecological benefits are realized within the bounds of private property rights and local oversight.
