Mexico has committed to taking immediate action to reduce shortfalls in its deliveries of Rio Grande water to the United States, a move aimed at meeting requirements outlined in the 1944 U.S.-Mexico water treaty. The agreement, reached following high-level discussions between the two countries in April, will see Mexico increase water deliveries through multiple sources.
As part of the deal, Mexico has agreed to transfer water immediately at Amistad Dam, followed by monthly transfers at the international reservoirs of Amistad and Falcon Dams. Additionally, the country will increase the U.S. share of flows in six Rio Grande tributaries designated under the 1944 treaty. Furthermore, Mexico will deliver an additional amount of San Juan River water, subject to U.S. acceptance of deliveries when they can be put to beneficial use.
These new deliveries come on top of 110,000 acre-feet of water already delivered by Mexico in the current water year, which started October 25, 2024. The agreement is a significant step towards ensuring that the Rio Grande water treaty requirements are met, and both countries will work together to monitor progress and make any necessary adjustments.
Mexico and the United States have agreed to meet again in July to assess hydrology conditions and evaluate the action taken since the new deliveries began. Ongoing meetings will also be held to develop a plan for Mexico to make up its shortfall from this five-year cycle and to ensure regular, dependable deliveries in the next five-year cycle.
The commitment made by Mexico is seen as a positive step forward in maintaining the health of the Rio Grande water treaty, which has been in place since 1944. By working together, both countries can ensure that users in Texas receive the water they need to thrive.
