Lake Tanganyika is an African Great Lake. It is estimated to be the second largest freshwater lake in the world by volume, and the second deepest, after Lake Baikal in Siberia; it is also the world's longest freshwater lake. The lake is divided among four countries – Burundi, Democratic Republic of the Congo (DRC), Tanzania and Zambia, with the DRC (40%) and Tanzania (46%) possessing the majority of the lake. The water flows into the Congo River system and ultimately into the Atlantic Ocean.
