Lake Khanka, the largest lake in Primorsky Krai, is located in the center of the Khankan lowland on the border with the People's Republic of China in Heilongjiang Province. 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. There are 24 rivers flowing into Lake Khanka, only one flowing - Songacha River, which connects it with Ussuri, and that in turn with Amur River System.

Its average volume is 18.3 cubic kilometres (4.4 cu mi), though it can fill up to 22.6 km3 (5.4 cu mi)The water in the lake is cloudy, which is explained by frequent winds and, as a result, strong mixing. On average, the flow to the lake is 1.94 km³ per year, from the lake about 1.85 km³.
On the northern (Chinese) shore there is the Malaya Khanka lake, separated from Khanka by a narrow sandy scythe. Lake Malaya Khanka belongs to China.

Here are represented meadows (from marshy to steppe), meadow forest, forest-steppe and steppe plant communities. In the lake itself there are many species of fish and aquatic invertebrates, many of which are endemic. In the lake there live 52 species of fish, among them such as carp, perch, silver carp, catfish, snakehead. On the banks of the nest and stop during the flight of a variety of birds.

It is fed by 23 rivers (8 in China and 15 in Russia), but the only outflow of the lake is the Songacha River.
The maximum monthly mean temperature is 20 °C (68 °F) in July, while the minimum monthly mean temperature is −21 °C (−6 °F) in January. Rainfall mainly occurs in summer, with average annual precipitation of 500-650 mm annually.
