The northern part of the lake belongs to the territory of China. The shape of the lake is pear-shaped with an extension in its northern part. The surface area of ​​the water is unstable, it varies depending on climatic conditions. In the maximum reaches 5010 km ², at a minimum - 3940 km ². The length of the lake is about 90 km, the maximum width is 67 km.

It is fed by 23 rivers (8 in China and 15 in Russia), but the only outflow of the lake is the Songacha River.
