The Sanaga River has its Source at the Adamawa Plateau.[2] It is formed by the confluence of the Djérem River and Lom River in the north of the East Region. Apart from those originating rivers, its main tributary is the Mbam River.[3]


The Sanaga River forms a boundary between two tropical moist forest ecoregions. The Cross-Sanaga-Bioko coastal forests lie to the north between the Sanaga River and the Cross River of Nigeria, and the Atlantic Equatorial coastal forests extend south of the river through southwestern Cameroon and Equatorial Guinea, Gabon, the Republic of the Congo, Cabinda and the Democratic Republic of the Congo.


The flow of the river was measured at Edéa in m³/s[1]
