It’s also the second oldest freshwater lake in the world, the second deepest, and the second largest by volume. The only lake greater than Lake Tanganyika is Lake Baikal in Siberia. The one record it holds is being the longest freshwater lake in the world.
Lake Tanganyika stores 4,500 cubic miles of water, covering an area of 12,700 square miles. The deepest point in the lake is 4,820 feet, and it averages a depth of 1,870 feet. This great depth is due to it lying in the Great Rift Valley.
