Cutzamala Dams Reach 97.4% Capacity: CONAGUA

The Cutzamala System’s reservoirs have closed their hydrological cycle at 97.4% of total capacity, the highest level in 10 years, according to Mexico’s National Water Commission (CONAGUA). Authorities no longer expect water levels to rise through the remainder of the year. Instead, they anticipate a gradual decline as the system begins supplying one-fifth of the Mexico Valley’s water demand.

“The system has reached a neutral point,” said Citlalli Peraza, Head of the Valley of Mexico Basin Water Agency (OCAVM). “Although some rainfall may continue into the end of the season, levels will start to drop in the coming weeks.”

During CONAGUA’s Technical Committee on Hydraulic Works session, Peraza reported that the El Bosque, Valle de Bravo, and Villa Victoria dams began the new hydrological cycle with 762.08 million m³ of stored water, equivalent to 97.4% capacity. This marks a 30.5% increase from the previous year, when storage stood at 523.63 million m³, or 66.9%.

“Last year, around this time, the Cutzamala System was entering a recovery phase,” Peraza noted. “Now, we are nearly at maximum storage capacity.”

The system currently supplies at a rate of 9.23 m³/s to Mexico City through the City’s Ministry of Comprehensive Water Management (SEGIA) and 15.6 m³/s to the State of Mexico via the State Water Commission (CAEM).

Water Security Outlook

Water management specialists project that with these historic storage levels, the Cutzamala System could ensure water supply stability through 2027. However, Conagua officials urged residents to use water responsibly to preserve this advantage.

“It’s essential to make this period of abundance sustainable,” Peraza said. “We must avoid waste to ensure long-term water security.”
