The world’s deepest lake is Russia’s Lake Baikal. The water’s average depth is more than 700 meters – almost half a mile. In some places, Lake Baikal is more than twice as deep as that. Lake Baikal is also the oldest lake in world. It began forming when a fissure in the Eurasian continent opened, more than 25 million years ago. If you exclude polar ice caps and glaciers, Lake Baikal holds over one-fifth of all surface fresh water on Earth. Unlike other deep lakes, it contains dissolved oxygen right down to the lake floor. That means creatures thrive at all depths in the lake.
