Background on the Water Treaty and Its Importance
The Tratado de Aguas de 1944, an international water agreement between Mexico and the United States, governs the allocation of water from six Rio Bravo tributaries. This treaty ensures that Mexico’s water deliveries to the U.S. do not jeopardize domestic water supply for human consumption or agricultural activities.
Key Provisions of the Treaty
- Annual water volume contribution from six Rio Bravo tributaries
- Flexibility to accumulate and regulate water deliveries over five-year cycles, especially during extraordinary drought conditions
- Allowance for unmet quotas during severe droughts, with the opportunity to make up the deficit in subsequent cycles
Recent Challenges and Solutions
Between 2020 and 2025, the Rio Bravo basin experienced one of its most severe droughts on record. This situation prevented Mexico from meeting the full water quota, as contemplated in the bilateral agreement. To address this, Mexico was granted an additional cycle until October 2030 to compensate for the shortfall.
Improving Water Management in the Border Region
Parallel to these treaty obligations, both countries have initiated projects to enhance water management in the frontier region. A technification program focuses on conservation and optimization efforts in irrigation districts 025 and 026 in Tamaulipas, as well as districts 005 and 009 in Chihuahua. These initiatives aim to bolster agricultural production and ensure water supply for the population.
Recent Water Allocation Agreement
On December 12, Mexico and the United States agreed to release 249 million cubic meters of water, a volume now available due to recent rains. The delivery will adhere to treaty stipulations while ensuring domestic water supply integrity.
Ongoing Dialogue and Future Planning
The Mexican foreign ministry emphasized that both nations maintain open communication to establish a delivery plan for the current cycle. This joint agreement must be finalized by no later than January 31, 2026, to ensure equitable resource administration for the benefit of populations on both sides of the border.
