Positive Impact of Intense Rainfall on Water Availability

According to Mexico’s National Water Commission (CONAGUA), the average filling level of the country’s 210 most important dams has increased from 44% at the beginning of June to 50% by August 10, 2025. This improvement comes after three years of below-average precipitation.

Background on CONAGUA and its Relevance

The National Water Commission (CONAGUA) is a Mexican government agency responsible for managing and conserving the country’s water resources. Its role is crucial in ensuring a stable water supply for both urban and rural populations, as well as supporting various sectors of the economy. Given Mexico’s geographical and climatic diversity, CONAGUA’s work is essential for maintaining water security across the nation.

Impact of 2025 Rainfall on Water Storage

The intense rainfall in 2025 has positively affected water availability in Mexico. From January 1 to August 10, 2025, the country recorded 386.8 mm of rainfall, which is 1.4% above the historical average for that period. This increase in precipitation has directly contributed to the notable recovery of national storage levels.

Current Status of Major Dams

As of August 10, 2025, the total volume of water in Mexico’s 210 principal dams reached 63,029 cubic kilometers (Mm³), representing half of their total storage capacity. The report details that 27 dams are at 100% of their capacity, 65 are between 75% and 100%, and 56 have a filling level between 50% and 75%.

Improvement in the Cutzamala System

The Cutzamala water system, which supplies a significant portion of Mexico’s Metropolitan Valley, has also shown substantial improvement.

  • Average storage level of the three reservoirs (El Bosque, Valle de Bravo, and Villa Victoria) is 64.8%, with a total volume of 506.79 Mm³.
  • This volume is considerably higher than the storage recorded on the same date in 2024, when it only reached 285.59 Mm³—an increase of 28.3%.
  • Valle de Bravo: 76.4%
  • Villa Victoria: 53.6%
  • El Bosque: 52.4%

CONAGUA’s Commitment to Sustainable Water Management

CONAGUA has reaffirmed its commitment to sustainably managing water resources, ensuring the human right to water and securing supply for various sectors of the Mexican economy. This commitment is part of the National Agreement on the Human Right to Water and Sustainability.
