Background on the Water Dispute and Key Players

The water dispute between Mexico and the United States has been ongoing for years, with Mexico falling behind in its water deliveries. The current president of Mexico, Claudia Sheinbaum Pardo, has taken action to address this issue by coordinating with state governments in Nuevo León and Tamaulipas to release water from their reservoirs.

Who is Claudia Sheinbaum Pardo?

Claudia Sheinbaum Pardo is the current Head of Government of Mexico City, serving since 2018. Although her role is primarily focused on the capital city, she has been instrumental in addressing national issues, including the water dispute with the United States. Her leadership and cooperation with state governments have been crucial in resolving this long-standing problem.

Why are Nuevo León and Tamaulipas relevant?

Nuevo León and Tamaulipas are two Mexican states that share a border with Texas. Their reservoirs, such as Presa el Cuchillo and Presa Marte R. Gómez, are crucial in providing water to the Rio Bravo (also known as the Rio Grande in the US), which is a vital water source for both countries. By releasing water from these reservoirs, Mexico aims to settle its hydration debt with the United States.

Water Release Details and Impact

On the morning of December 23, the government of Nuevo León ordered the release of water from Presa el Cuchillo to address part of Mexico’s hydration debt to the US. This action was taken without a formal announcement from the National Water Commission (CONAGUA). The nearby municipality of General Bravo also informed residents about the release, warning them to stay away from the Rio San Juan due to potential increased water levels.

Presa el Cuchillo was expected to release approximately 100 hectares cubic meters (hm³), reducing its storage from 81% to 65%. Meanwhile, Presa Marte R. Gómez in Camargo, Tamaulipas, released 42 hm³, as reported by the US section of the Comisión de Límites y Aguas (CILA).

The combined release from both reservoirs totals 310 hm³, aiming to alleviate the threat posed by US President Donald Trump of imposing a 5% tariff on Mexican products if the country fails to deliver at least 240 hm³ before year-end. This amount is part of the 900 hm³ Mexico owes from the 2020-2025 period.

Agreement with Governors

Claudia Sheinbaum Pardo confirmed the start of water delivery to the US while assuring that the involved states would experience minimal impact. She stated that she worked with all governors to create a scheme minimizing effects on farmers, especially in Coahuila, Nuevo León, Tamaulipas, and Chihuahua. All governors agreed to this plan.

  • How much water will be released? Approximately 310 hm³ of water will be released from both reservoirs to settle Mexico’s hydration debt with the US.
  • What are the potential impacts on local communities? The governments of Nuevo León and Tamaulipas have agreed on a plan to minimize the effects on local farmers. However, Tamaulipas is expected to be more affected due to the water release.
