Sinaloa dams reach significant water surplus amid seasonal rainfall

Sinaloa's dams have reached a significant water surplus due to recent rainfall during the 2026 season. According to reports from the National Water Commission (Conagua), the state's reservoirs currently hold between 8,590 and 8,644 million cubic meters of water, representing approximately 54.6 to 54.9 percent of their total conservation capacity. This marks a substantial increase compared to the same period last year.

Key reservoirs include the Huites dam in Choix, which is at 86.8 to 87.4 percent capacity, and the Eustaquio Buelna dam in Salvador Alvarado, which is nearing 90 percent. Other notable levels include the Gustavo Díaz Ordaz dam at roughly 63 percent and the Sanalona dam, which has seen significant recovery in recent weeks.

While the water reserves are high, recent rainfall has caused localized infrastructure challenges. In Culiacán, the Humaya river basin recorded the highest rainfall at 57 mm within 24 hours. Despite lower rainfall totals, areas such as Guasave and Los Mochis experienced street flooding, highlighting potential issues with the capacity of local drainage and pluvial systems to manage runoff.
