The Sanaga in Edea
It has two source rivers, the Djérem and the Lom . The Djérem rises in the highlands of Adamaua at 1150 m, the Lom in the highlands of Jadé at 1200 m. In most sources, the Sanaga takes its name after the confluence of the Lom and Djérem rivers. The rough direction of flow of the Sanaga is oriented from east-northeast to west-southwest. Most of the vegetation along the upper reaches is tree savannah , but changes to the middle and lower reaches of the tropical rainforest . In the lower reaches of the river it forms the boundary between the two vegetation areas.
The largest tributary of the Sanaga is the Mbam .
The flow rate of the river was measured for 37 years (1943–1980) in Edéa, about 70 km above the mouth in m³ / s.
Due to the strong seasonal fluctuations in the flow of the Sanaga (factor 10), a combination of reservoirs was created in the system of Cameroon's largest river. The Mbakaou Lake , the Bamendjing and the Mapé Reservoir , as well as other smaller reservoirs, are not used directly to generate electricity. The national energy producer Eneo (formerly AES Sonel) uses these reservoirs to regulate the amount of water in the Sanaga. This compensates for the fluctuations in the flow of the Sanaga and optimizes the power generation of the Edéa and Song Loulou power plants on the lower reaches of the Sanaga, which supply the electricity required for aluminum production in the region. In addition, the Lom Pangar power plant was built on the Lom , the reservoir of which can store 6 billion m³ of water, but which, in addition to the storage factor , is also used to generate energy.
