Mexico Faces Water Delivery Shortfall to U.S. Under 1944 Treaty
Table of Contents
Mexico is unlikely to meet its water delivery obligations to the United States, as stipulated in the International water Treaty of 1944, according to the Mexican section of the International limit and Water Commission (CILA). Official figures indicate a notable deficit in water transfers.
Treaty Obligations and Current Deficit
The treaty mandates that the U.S. provide 1.85 billion cubic meters of water annually from the Colorado River. In return, Mexico is to contribute 2.185 billion cubic meters from the Rio Bravo over each five-year cycle. However, due to persistent water scarcity, Mexico has accumulated a debt of 1.52 billion cubic meters.This raises its commitment to 3.705 billion cubic meters for the upcoming cycle, wich begins Oct. 25, 2025.
Dam Levels Reflect Water Crisis
Manuel Morales, head of the Water Quality Department of CILA Mexico, stated at a press conference that the Friendship dams in Coahuila and Falcon in Tamaulipas are at only 21% and 12% of their capacity, respectively. “This reflects the severe shortage of water, drought, which prevails in the Rio Bravo basin,” Morales said.
Drought Conditions Widespread
The Drought Monitor of Mexico reported that as of March 15, approximately 58.5% of the country is experiencing some level of drought, with the most severe impacts felt in the northwest and northern regions.
The 1944 Water Treaty: A Cornerstone Agreement
The Water Treaty of 1944, formally known as the “Treaty related to the use of the waters of the Colorado, Tijuana and Bravo rivers,” was signed Feb. 3, 1944, and remains in effect.Its primary goal is to regulate the utilization and distribution of water from shared border rivers, ensuring equitable allocation for agricultural, industrial, and urban needs in the arid regions of northern mexico and the southern U.S.
Key Provisions of the Treaty
Under the treaty, the United States is obligated to provide Mexico with an annual volume of 1.85 billion cubic meters of water from the Colorado River. This delivery occurs near Yuma, Arizona, destined for Baja California.
Conversely, Mexico commits to delivering a total of 2.185 billion cubic meters of water from the Rio Bravo (Rio Grande) to the United States every five years. This supply relies on the flow of tributaries originating in Mexican territory, including the Conchos, San Diego, San Rodrigo, Escondido, and Salado rivers.
CILA’s Role in Treaty Oversight
The International Limit and Water Commission (CILA),a binational entity with sections in both countries,is responsible for the implementation and supervision of the treaty. CILA monitors water transfer volumes, coordinates deliveries, and resolves any disputes arising from compliance with the agreement.
Adaptability and Potential Conflict
The treaty includes provisions for exceptions in cases of force majeure, such as prolonged droughts, allowing a country to accumulate water debt and compensate for it in the subsequent five-year cycle. However, this flexibility is subject to ongoing review and can become a point of contention if either party deems the breach unjustified or excessively prolonged.
The situation has strained diplomatic relations between the two nations. In late March, the U.S. State Department reportedly denied a request from Mexico to receive water from the Colorado River for Tijuana, allegedly in response to the treaty breach.
Mexico’s Water Delivery Shortfall: A Q&A Guide to the 1944 Treaty
This article answers common questions about the water delivery issues between Mexico and the U.S., focusing on the 1944 International Water Treaty.
What is the 1944 Water Treaty and Why is it Critically important?
The 1944 Water Treaty, formally known as the “Treaty related to the use of the waters of the Colorado, Tijuana, and Bravo rivers,” is a cornerstone agreement between the United states and Mexico. Signed on February 3, 1944, it regulates the use and distribution of water from shared border rivers, ensuring equitable allocation for agricultural, industrial, and urban needs in the arid regions of northern Mexico and the southern U.S. It remains in effect today.
What are the Key Obligations of the Treaty?
Under the treaty, the obligations are as follows:
- United States to Mexico: The U.S. is obligated to provide Mexico with an annual volume of 1.85 billion cubic meters of water from the Colorado River. This water delivery occurs near Yuma, Arizona, and is destined for Baja California.
- mexico to United States: Mexico is committed to delivering a total of 2.185 billion cubic meters of water from the Rio Bravo (Rio Grande) to the united States every five years.This water supply relies on the flow of tributaries originating in Mexican territory.
Is Mexico Meeting its Water Delivery Obligations?
no, Mexico is currently facing a significant water delivery shortfall and is unlikely to meet its obligations set forth in the 1944 treaty. According to the Mexican section of the International Boundary and Water Commission (CILA), ther is a notable deficit in water transfers.
How Big is the Current Water Deficit?
Mexico has accumulated a debt of 1.52 billion cubic meters of water. According to the source material,this means Mexico’s commitment for the upcoming cycle,wich begins October 25,2025,will be 3.705 billion cubic meters.
What Evidence is There of a water Crisis?
There is significant evidence of a water crisis:
Dam Levels: Dam levels are extremely low. For example,the Friendship dams in Coahuila and Falcon in Tamaulipas are at only 21% and 12% of their capacity,respectively.
