Senegal River
The Fonta Djallon in Guinea is the source of the Bafing River, north of Mamou. It flows for about and converges with the Bakoy River to join the Senegal River in western Africa. The Bafing River is the largest tributary of the Senegal River, and contributes almost half of its total water volume. The Bafing forms part of the international border between Guinea and Mali.
