LEGENDS: Baikal had an only daughter - Angara. She fell in love with Yenisei and decided to run away to him. Baikal, learning about this, tried to block her path, threw the Shaman-stone, but Angara ran on, then Baikal sent his nephew Irkut after her, but he took pity on Angara and turned off the path. The Angara met with the Yenisei and flowed further, along with it. Since ancient times, the Shaman-stone was endowed with unusual power.

And if at night the waters of Lake Baikal did not wash him off, then the criminal was justified.

In order to realize the immensity of the Baikal water body, imagine that the Angara, which annually takes out 60.9 km 3 of water from the lake, would need 387 years of continuous work to drain its bowl. Provided, of course, that during this time not a liter of water gets into it and not a drop evaporates from its surface.
