Colombia's Ituango hydroelectric plant recorded the lowest discharge of the recent period at 15.93 GWh but completed 35 consecutive days of spillovers due to climatic contingency and water volatility. The reservoir reached 98.8% fill level, while Chuza dropped to a critical low of 30.0% and Muña recovered to 46.6%.
The Superintendencia de Servicios Públicos Domiciliarios (Superservicios) reported that despite Ituango's lowest recent discharge of 15.93 GWh, the reservoir completed 35 consecutive days of spillovers due to climatic contingency and national water volatility. Its fill level stood at 98.8%, approaching system equilibrium.
In Bogotá's water system, the crisis intensifies: Chuza fell to 30.0%, its lowest point, with the Chuza river at just 0.34 m³/s (6% of historical average). Muña advanced to 46.6%, boosted by the Bogotá river reaching 282% of historical levels. "In contrast, the Bogotá river reaches 282% of the historical average, which has driven Muña out of the most critical zone of the period," Superservicios specified.
Rivers showed mixed trends: Cauca at Ituango rose to 885.5 m³/s (117% historical), alongside increases in Sogamoso, Betania, El Quimbo, and San Carlos (184% historical). However, Blanco river reported zero flow, and Guavio and Bata basins fell below average.
Of Colombia's 24 national reservoirs, 13 are below 80%, five between 80-90%, and six between 90-100%. The highest are Ituango (98.8%), Calima 1 (98.6%), and Miraflores (93.8%). The lowest include Altoanchicayá (21.1%), Chuza (30.0%), and Porce II (40.1%).
