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.

Historical Context and Relevance

CONAGUA’s report highlights the significance of this development, as it directly results from the increased rainfall. 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.

Current Dam Levels

As of August 11, the total volume of water in the principal dams reached 63,029 cubic kilometers (Mm³), representing half of their 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 system, which supplies a significant portion of Mexico’s Metropolitan Valley, has also shown substantial improvement.

  • Average storage level of its three reservoirs (El Bosque, Valle de Bravo, and Villa Victoria) is at 64.8%, with a volume of 506.79 Mm³.

This volume is considerably higher than the storage recorded on the same date in 2024, when it was only 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 reaffirmed its commitment to managing water sustainably, ensuring the human right to water and maintaining supply for various productive sectors in Mexico as part of the National Agreement on the Human Right to Water and Sustainability.
