S.B. No. 2406 amends the governance structure of the Sabine River Authority of Texas, implementing recommendations from the Sunset Advisory Commission. Key changes include extending the review period under the Texas Sunset Act to every 12 years, with the next review scheduled for September 1, 2037. The bill establishes that the Board of Directors will consist of nine members appointed by the Governor, with staggered terms of four years. It also specifies that four members must reside in the upper basin and four in the lower basin of the Sabine River, while one member must reside within the watershed.

Additionally, the bill introduces new grounds for the removal of board members, including failure to maintain qualifications, violation of local government laws, and excessive absences from meetings. It mandates that newly appointed directors complete a training program before participating in board activities and requires the district to maintain a system for handling complaints. The bill also emphasizes the separation of policy-making and management responsibilities within the district. These changes aim to enhance accountability and operational efficiency within the Sabine River Authority. The act is set to take effect on September 1, 2025.
