He is also the second largest lake in the world by volume and depth, behind the Lake Baikal and its waters join the Congo Basin and the Atlantic Ocean. \ Its formation dates back to about 20 million years.

Tanganyika Lake is considered the best fishing lake in the world. It includes nearly 200 species of cichlids and more than 150 non Cichlidae. It should be noted that many of them are endemic.
An unusual water
The lake is known for its exceptionally clear waters, the latter allowing visibility reaching 25 meters.
The water of Tanganyika Lake is extremely rich mineral, and its parameters are very specific. Its conductivity is about 609-620 µS, its pH is 9.5 at the surface and from 8.6 to -1300 m; TAC of 12-19, low value in terms of proportions of salts. \ Beyond two hundred feet deep, life is not superior beings, the absence of oxygen, replaced by hydrogen sulfide, as does the maintenance of anaerobic bacteria (sulfate reducing). Prevailing winds during the austral summer (from the south-east) cause of this ski area anoxic. Fish living in these areas have no choice but to flee or die. \
