Drought-stricken dams in Mexico's Valley are rebounding following hefty rainfall, now holding 64.90% of theirstorage capacity.
Heavy Rains Boost Water Reservoirs in Cutzamala System
The Cutzamala System, a crucial water supply for Mexico City and surrounding regions, has seen a significant increase in its water reservoirs this year. According to the latest reports, the system's water storage has risen to approximately 64.8% of its capacity, equating to around 506.79 million cubic meters [1].
This marked increase, which represents a 28.3% rise compared to previous drought periods, is largely due to the strong rainy season that started reversing drought conditions across central Mexico [3]. In July, water levels were close to 60% capacity and have nearly doubled since the prior summer when drought was severe [2][4].
The Valle de Bravo dam, one of the key reservoirs in the Cutzamala System, currently holds 298,300 liters, which is 76.5% of its capacity [2]. Another dam, El Bosque, contains 102,785 liters, which is 52.71% of its capacity [1]. However, no information about the current status of other dams in the system was provided.
Looking ahead, meteorological agencies forecast that the rainy season will continue near or slightly above historic averages through September, the rainiest month in Mexico. This suggests further improvements in reservoir levels and drought relief [5]. However, localized risks remain, including heavy rain events and potential tropical cyclone developments, such as Invest 98 in the Gulf of Mexico, which could bring variable impacts [5].
Overall, the data indicates a strong recovery in the Cutzamala System's reservoirs, offering optimistic projections for sustained rainfall to support water security in Mexico City and surrounding regions in the near term.
Key Points:
- The Cutzamala System's water reservoirs have significantly increased, reaching approximately 64.8% capacity (506.79 million m³) by mid-August.
- This 28.3% increase is a result of three consecutive years of above-average rainfall.
- The Valle de Bravo dam currently contains 298,300 liters, which is 76.5% of its capacity.
- The El Bosque dam currently contains 102,785 liters, which is 52.71% of its capacity.
- Future rain forecasts suggest that the rainy season will continue near or slightly above historic averages through September.
- Potential localized risks, such as heavy rain events and tropical cyclone developments, remain a concern.

The significant rise in the Cutzamala System's water reservoirs, as seen in mid-August, has been attributed to the science of climate-change, with three consecutive years of above-average rainfall supporting environmental-science theories about weather patterns. As more rain is forecast for September, the weather could continue to play a critical role in the recovery of the system, ensuring a steady supply of water for Mexico City and its surrounding regions.
