The Sélingué Dam is a single purpose hydroelectric dam located in the Koulikoro Region, on the Sankarani River, one of the affluents of the Niger River. It is the second most important center of energy production of Mali. Its construction, at the cost of 140 million US dollars, was financed by several backers. Of a total power of 44 megawatts, the dam has an energy output of 200 million kilowatt-hours per year. The dam provides Bamako, Kati, Koulikoro, Ségou, Fana, Dioïla, Yanfolila and Kalana with electricity. It was brought into service in 1980, and renovated between 1996 and 2001.
Its retaining basin forms the 409 km² artificial Lake Sélingué, which allows agriculture on the irrigated perimeters, managed by the Office of Rural Development of Sélingué, as well as fishing (fish available in Bamako comes mainly from Lake Selingue).
