Lake Tanganyika

Congo (Dem. Rep.) / Katanga / Kalemie /
Lake Tanganyika is situated within the Western Rift of the Great Rift Valley and is confined by the mountainous walls of the valley. It is the largest rift lake in Africa and the second largest lake by surface area on the continent. It is the deepest lake in Africa and holds the greatest volume of fresh water. It is estimated to be the second largest freshwater lake in the world by volume, and the second deepest, in both cases after Lake Baikal in Siberia.
