Cutzamala System Reaches Decade-High Water Levels

The Cutzamala System in Mexico achieved its highest water storage level in ten years, reaching 71.46% capacity thanks to the 2026 rainy season. The system, which supplies water to Mexico City and the State of Mexico, has gained 33.60 million cubic meters of water since June 4.

The three reservoirs feeding the system, Valle de Bravo, Villa Victoria, and El Bosque, currently stand at 79.07%, 66.40%, and 61.28% capacity respectively. Currently, the system delivers 15,000 liters per second to the Valley of Mexico, one of the highest rates in its history.

Authorities anticipate the system will reach 98% capacity by the end of October, similar to 2025’s successful closure. However, officials regulate water levels to prevent overflows and protect surrounding communities, meaning the reservoirs will not reach 100% capacity. The increased storage ensures a more secure water supply for millions of residents.
