What's the deepest lake in the world?
Lake Baikal, located in Southern Russia, is known to be the world's deepest lake. The lake, with an estimated depth of 5,387 feet and a bottom of approximately 3,893 feet below sea level, is also the world's largest freshwater lake by volume. Its location in an active continental rift zone which widens at a rate of about 1 inch per year, contributes to its continued widening and deepening.
