(The Center Square) – U.S. Sens. Ted Cruz and John Cornyn, Republicans from Texas, have filed a bill to hold Mexico accountable for failing to provide water to south Texas in accordance with a 1944-era treaty. 

The Ensuring Predictable and Reliable Water Deliveries Act of 2025 would strengthen enforcement of the 1944 Treaty of Utilization of Waters, which governs water usage between the U.S. and Mexico, including from two international reservoirs, Lake Amistad and Falcon Lake in Texas along the international border.
