Lake Baikal is recognized as the deepest lake in the world, reaching a maximum depth of approximately 1,642 meters (5,387 feet). Located in Siberia, Russia, it is not only the deepest lake but also the most voluminous freshwater lake, containing about 20% of the world's unfrozen freshwater supply. Its unique geological formation makes it a rift lake, formed by the separation of tectonic plates. The age of Lake Baikal, estimated to be around 25 million years, contributes to its significance in aquatic biodiversity, hosting numerous species found nowhere else on Earth.

In contrast, while Lake Tanganyika is also quite deep (second deepest in the world) and the Caspian Sea is technically a lake that covers a large area, they do not reach the depths that Lake Baikal does. Lake Geneva, although beautiful and historically significant, is much shallower than Lake Baikal.
