Cahora Bassa Reservoir
Cahora-Bassa District, Mozambique
The Cahora Bassa lake—in the Portuguese colonial era (until 1974) known as Cabora Bassa, from Nyungwe Kahoura-Bassa, meaning "finish the job"—is Africa's fourth-largest artificial lake, situated in the Tete Province in Mozambique. In Africa, only Lake Volta in Ghana, Lake Kariba on the Zambezi upstream of Cahora Bassa, and Egypt's Lake Nasser are bigger in terms of surface water.
