Adamawa Plateau
The Lagdo Reservoir is formed by a dam at Lagdo that traps waters from the Benoue and its smaller tributaries the Mayo Godi, Mayo Rey, Mayo Sina, Mayo Oldiri, and others, many of which rise on the Adamawa Plateau. The reservoir provides an important source of hydroelectric power for Cameroon's three northern provinces. Local villagers also use it as a source of fish, and both the lake and the river are used for irrigation.
