The Sanaga River has its source at the Adamawa Plateau.[3] It is formed by the confluence of the Djérem and Lom Rivers in the north of the East Region. Djérem River has a total length of 464.5 km (288.6 mi) and Lom River a total length of 424.2 km (263.6 mi). Apart from these originating rivers, the largest tributary of Sanaga is Mbam River with a total length of 548 km (341 mi).[4]
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]
