Water; prohibiting certain uses and actions in certain location. Effective date.

SB 1933 prohibits nonlocal municipalities and counties from diverting water in specific river segments (Kiamichi River from Highway 3 bridge to Arkansas line, and Glover River from Little River confluence east/west branches) for commercial, agricultural, or power generation purposes. It bans building dams, impoundments, or diversion structures in these areas and restricts local farming/ranching activities there. The bill defines "nonlocal" as entities outside 10 miles of a river's main channel and exempts pre-existing water uses and structures. It becomes effective November 1, 2026.
