What Is The Coldest Lake In The World?

The coldest lake in the world is Lake Baikal in Russia. It is also the deepest lake in the world, reaching a depth of over 5,000 feet. The average temperature of the water at the surface is about freezing, but it can get much colder at depths. In fact, Lake Baikal is sometimes called "the icebox of Russia" because it stays frozen for much longer than other lakes in the country.
