Lake Tanganyika
Lake Tanganyika is the world's second-deepest lake and the longest freshwater lake on Earth, spanning four Central African countries and hosting extraordinary aquatic biodiversity.
Stretching across the borders of four different countries, this ancient rift lake holds enough water by volume to rank among the very largest freshwater bodies on the planet, despite its narrow, elongated shape.
The World's Longest Freshwater Lake
Lake Tanganyika stretches roughly 420 miles in length, making it the longest freshwater lake in the world, though its narrow width keeps its surface area more modest than some other Great Lakes.
The Second-Deepest Lake on Earth
The lake reaches a maximum depth of 1,470 meters (4,823 feet), placing it second only to Lake Baikal among the world's deepest lakes.
Shared Among Four Nations
Tanganyika's shores are shared by Tanzania, the Democratic Republic of the Congo, Burundi, and Zambia, making coordinated management of the lake's resources an ongoing regional challenge.
Extraordinary Biodiversity
The lake hosts remarkable biodiversity, including hundreds of unique cichlid fish species found nowhere else, making it a significant site for evolutionary biology research.
An Ancient Fishing Tradition
Human communities have fished along Tanganyika's shores since the Stone Age, and the lake remains a vital food and economic resource for millions of people living along its coastline today.
