Sanaga River
Stream Cameroon's longest river, flowing to the Gulf of Guinea
The Sanaga River runs westward across Cameroon into the Gulf of Guinea, supporting fisheries, riverine towns and transport; river crossings and estuary wetlands attract local commerce and occasional boat travel.
The Sanaga River is Cameroon’s largest river by volume and a principal drainage artery that flows toward the Gulf of Guinea in the Littoral region. It plays a central role in the country’s hydrology and power generation.
Along its course are hydroelectric installations and stretches of riverine forest; the lower reaches form an estuary complex near the port city of Douala. The river is important for inland transport, local fisheries and regional water resources.
The river basin has long supported human settlements and transport routes; in the 20th century hydroelectric projects were developed on the Sanaga to supply power for industry and cities.
The Sanaga flows westward across central Cameroon into the Gulf of Guinea near Douala, draining upland areas of the interior as it approaches the coast.
- Hydropower plants: Major hydroelectric installations are located on the Sanaga, including Song Loulou and Edea dams, which support regional power generation.
- Estuary and drainage: The river drains a large portion of central Cameroon and discharges into the Gulf of Guinea near Douala, forming an estuary used by coastal commerce.
