So, as a lake, the Baikal is the world's deepest lake. The water in it is so clear that if you look down you can count the stones on the bottom (through 60 metres of water!). It is the same type of lake as Tanganyika in Africa.

The kind of storm, known as the sarma, can tear the roofs off the houses in the shoreline villages, to overturn launches and to throw sheep down the cliffs into the roaring waters. The sarma reaches a speed of forty or more metres a second. The Baikal, as a sea, has different kinds of winds – almost from every river’s valley. The most famous of them are called after the rivers – the barguzin, the sarma, the kultuk.
