Burkina Faso’s two major hydroelectric dams, Bagré and Kompienga, are recording strong water levels, with both reservoirs now more than 77 percent full as the country continues to monitor the impact of rising inflows.
Data released by the national electricity company, SONABEL, showed that as of August 15, 2026, the Kompienga Dam had reached a filling rate of 77.17 percent, while the Bagré Dam stood at 77.35 percent.
The Kompienga reservoir recorded an upstream water level of 177.65 metres, just 2.35 metres below its normal level of 180 metres.
SONABEL said one of the dam’s gates has remained open at 0.50 metres since January 1, 2026, allowing water to flow at a rate of approximately 18.41 cubic metres per second.
At Bagré, the upstream water level was measured at 233.24 metres, leaving the reservoir 1.76 metres below its normal level of 235 metres.
SONABEL prepares for possible water release
While the current levels remain below the normal reservoir thresholds, SONABEL has warned that it could be forced to release water from the Bagré Dam if the level continues to rise.
The company said the spillway gates could be opened once the reservoir reaches 234.75 metres.
SONABEL assured the public that should the threshold be reached and controlled water release become necessary, it would provide advance notice of the date and time of the operation.
The precautionary measure is intended to allow communities and other stakeholders downstream to prepare adequately for any increased water flow.
Hydropower supply in focus
The latest figures are significant for Burkina Faso’s electricity sector because Bagré and Kompienga are important sources of hydroelectric power for the country.
The continued monitoring of their water levels is therefore crucial for both electricity generation and dam safety, particularly during periods of increased rainfall and inflows.
SONABEL’s latest update suggests that the reservoirs have maintained substantial water storage, while the company’s warning on possible spillage at Bagré highlights the need for continued vigilance as water levels approach critical thresholds.
Authorities are expected to continue monitoring the reservoirs and keep the public informed should conditions require further water releases.
