Under the water treaty of 1944, Mexico delivers water from the Río Bravo, the Rio Grande, to the United States in five-year cycles. The cycle that ended on October 24, 2025 set a quota of 2,158.6 million cubic meters.
According to Expansión, Mexico sent 1,091 million. The cycle before it, UnoTV wrote, had also “cerró con un adeudo que tuvo que compensarse en el siguiente periodo” (closed with a debt that had to be made up in the following period).
Mexican authorities said the shortfall could be repaid until October 24, 2030. The United States said it was due when the cycle ended. On December 12, 2025, the two governments announced an agreement on “el cumplimiento del ciclo de entrega actual y el déficit que se registró en el anterior” (compliance with the current delivery cycle and the deficit recorded in the previous one).
