Ghanaian authorities have placed 68 communities in the Northern region on high alert for potential flooding from Burkina Faso's Bagre Dam. The National Disaster Management Organisation (NADMO) activated precautionary measures after receiving notification of a possible water release. This comes despite the dam's water level remaining below the critical spillage threshold.
Burkina Faso’s electricity company, SONABEL, initially informed Ghana of its intention to spill the dam on August 11, 2026. However, this decision was put on hold due to lower-than-expected rainfall upstream. The Bagre Dam's water level stood at 233.08 metres as of August 10, 2026, which is 1.92 metres below the spillage threshold of 234.15 metres.
The annual Bagre Dam spillage frequently impacts communities along the White Volta Basin in Ghana, leading to displacement and destruction of livelihoods. This recurring event highlights the interconnectedness of water resource management between Ghana and its northern neighbour. Ghana's economy, particularly its agricultural sector, is vulnerable to such environmental events.
Mr. Idresu Abdubakari Ziblim, Chief Disaster Control Officer at NADMO, confirmed the ongoing monitoring. He stated, "We received information from our partners from Burkina Faso, that is SONABEL, of their intention to spill the Bagre Dam on the 11th of August 2026, that is today." He added that the decision was delayed due to low rainfall upstream, preventing the dam from reaching full capacity.
NADMO has identified four districts as most vulnerable: Tolon, Kumbungu, Savelugu Municipal, and Karaga Municipal. These districts collectively contain the 68 communities now on alert. Emergency response teams, including a rapid response team from the 51st Regiment of the Ghana Armed Forces, are being prepositioned. The Ghana Health Service has also been alerted to replenish anti-snake venom and other medical supplies, anticipating increased health risks during floods. Cholera and other waterborne diseases are a major concern, prompting the distribution of Aquatabs for water disinfection.
The proactive measures are a direct result of lessons learned from past Bagre Dam spillages. Mr. Ziblim recalled the 1997 and 1998 floods, which led to 20 fatalities due to unexpected water releases. NADMO has appealed to Burkina Faso authorities for controlled water releases to allow for better management by Ghanaian regions. Farmers and herders along the White Volta Basin have been advised to move their animals and harvest mature crops to higher ground. This vigilance aims to prevent casualties, as was achieved during last year's flooding due to joint monitoring efforts.
