The lake basin shape falls into the river. It is considered that Baikal is nourished by 336 rivers. However, a number of small streams reaches one thousand, and each of them contributes to the filling of the lake. Flows out of Grand lake only one Hangar. Each year the Hangar comes out of the lake about 60 cubic kilometers of water, feeding and supplying clean drinking water to nearby cities.
