Lake Baikal is injected by 336 rivers, including the Selenger River, with a catchment area of 557,000 square kilometers. The Angara River, a tributary of the Yenisei River, flows from here, and there are 27 small islands in the lake. Because it is not covered by Quaternary glaciers, there are still tertiary freshwater animals in the lake, such as Baikal seal, white fish, Amur fish, sharks and so on. The lake is an important fishing ground in Russia and has a great influence on the climate in this area.
