H.B. No. 2109 introduces a new provision to the Texas Water Code, specifically Section 16.0511, which mandates the removal of proposed reservoir projects from the State Water Plan if construction has not commenced within 50 years of their inclusion in the plan. This provision applies retroactively to any proposed reservoir project that has been part of the State Water Plan for the past 50 years or more. Once a project is removed by the executive administrator, it cannot be included in any future versions of the plan.

The bill aims to streamline the State Water Plan by eliminating outdated projects that have not progressed towards construction, thereby ensuring that the plan remains relevant and focused on viable water management solutions. The act is set to take effect on September 1, 2025.
