The average annual rainfall in the mountains of the Altai Mountains is 400-500 mm, which is much higher than the rainfall in the prefecture. Also, in the mountains of the Altai Mountains, various conditions such as dry and hard land, very few trees in the mountains, and many rocky mountains cause the rain and thaw water to flow out immediately. The water that flows out in this way creates rivers in various places and lakes in the lower places. In the land of Bayan-Ulgii, you can see very clear and beautiful rivers and lakes.
