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. … The bill would impose restrictions and measures against Mexico if it does not meet its average annualized obligation. It requires the secretary of State to report to Congress on Mexico’s status of meeting its treaty obligations. If the secretary finds that Mexico hasn’t met its obligations, the bill directs the president to deny all non-treaty requests from the Mexican government.
