Guanajuato dams reach 101% capacity; flood risk alert issued

1337

The Ministry of Water and Environment (SMAOT) issued a flood risk alert in Guanajuato after the state’s main dams reached an average of 101.3% storage capacity, equivalent to 1.85 billion cubic meters of water.

This critical level is due to the intense rainfall recorded in September, which averaged 88.1 millimeters and reached an annual total of 646 millimeters, a figure that already exceeds the 620.8 millimeters reported during the same period in 2024.

Municipalities at risk and history of flooding
The overflowing capacity represents a direct risk to communities near water bodies such as El Palote, La Esperanza, La Soledad, and La Mata, which have also reached 100% capacity in recent years.

In July 2025, the El Palote Dam, located in León, exceeded 10 million cubic meters of water, breaking its record from 2021, when it reached 121.41% fill. The historical record remains at 140.34%, set in 2018.

Furthermore, in August 2024, several dams in the state reported levels above 90%, resulting in controlled releases and impacts in municipalities such as Salamanca, Irapuato, and Valle de Santiago.

Recommendations for the rainy season

State and municipal authorities urge the population to take preventive measures, as the rainy season is not yet over and continued storms are expected in various regions. Recommendations include:

Avoid crossing rivers, streams, or streets with strong currents, even in vehicles.
Keep important documents in plastic bags or high places.
Disconnect electrical appliances during intense storms.
Store drinking water and non-perishable food in case of emergency.
Locate temporary shelters and call Civil Protection emergency numbers.
Clean rooftops, drains, and gutters to prevent blockages.
Follow official communication channels to receive real-time alerts.
