Senegal River

The Senegal River, in West Africa, forms the border between Senegal and Mauritania.

It is formed by the confluence of the Semefé[?] and Bafing[?] rivers. Both have their source in Guinea; the Bafing River flows through Mali, and the Semefé is on the Malinese-Senegalese border.

Approaching its mouth, the Senegal passes through Biffeche and the island on which the city of Saint-Louis, Senegal[?] is located, then turning south. It is separated from the Atlantic Ocean by a thin strip of sand called the Langue de Barbarie[?] before it pours into the ocean itself. The river has two large dams along its course, the Manantali Dam[?] in Mali, and the Maka-Diama dam[?] on the Mauritania-Senegal border, near the outlet to the sea.

The Senegal River has a drainage basin of 483,181 km² and an estimated annual discharge of 8 million km³. Important tributaries are the Faleme River[?], Karakoro River[?], and the Gorgol River[?].
