Overview
- Mexico is starting staged releases totaling 249.163 million cubic meters this week, the Foreign Ministry said in a joint statement with the United States.
- The deliveries are framed by the 1944 Water Treaty, and both governments are negotiating a technical route to cover the current cycle and the previous-cycle deficit, with a plan slated for completion by Jan. 31, 2026.
- President Claudia Sheinbaum emphasized that releases are based on real hydrologic availability and will not affect human consumption or agricultural production in northern states.
- Domestic experts and opposition figures pressed for transparency on water sources, with PAN deputy Federico Döring questioning how Mexico will supply more than the roughly 201 million cubic meters reportedly stored in the La Amistad and Falcón reservoirs.
- Acta 331, signed in 2024, allows conditional use of San Juan and Álamo waters through 2029, and a separate Acta 333 signed Dec. 15 launches binational sanitation projects for the Tijuana–San Diego region from 2026 to 2028.
