is a large artificial lake
, formed by the 1989 construction of the Manantali Dam
, on the Bafing River
. Its northern point is located 90 km to the south-east of the city of Bafoulabé
Lake Manantali covers 477 km² and contains 11.3 billion m³ of water. Its formation forced 12,000 people from their homes and flooded 120 km² of forest. The lake largely ended the flood patterns on both the Bafing and Senegal Rivers
, compromising traditional agriculture which depended upon seasonal flooding. The lake has created benefits as well: consistent navigation downstream of the dam, use of for irrigation of surrounding land, and a source for commercial fishing. The dam itself provides hydroelectric power through much of the region.
