U.S., Mexico Set Annual Rio Grande Deliveries and Debt Repayment Plan

Overview

• Mexico will provide at least 350,000 acre-feet of water each year to the United States during the current five-year cycle under the 1944 Water Treaty.
• Mexico committed to a detailed plan to fully repay outstanding shortfalls from the previous cycle.
• Both governments agreed to hold monthly meetings to track flows, with the State Department, USDA and the International Boundary and Water Commission coordinating.
• The arrangement emphasizes predictable yearly deliveries in a treaty that otherwise measures compliance over five-year totals, while U.S. Colorado River deliveries to Mexico continue under the same framework.
• The announcement follows a call between President Donald Trump and President Claudia Sheinbaum after drought left Mexico delivering roughly half of its required Rio Grande water in the last cycle.
