Lake Khanka on Russian-Chinese Border Still Ice-Covered
Khanka Lake is a transboundary freshwater body located on the border between Heilongjiang Province in northeast China and Primorsky Krai in Russia.
Khanka Lake is actually two lakes separated by a 10 m sandy hill. The shores of the lake are swampy, except in the north-west.
The lake’s drainage basin is an alluvial plain of around 16,890 km², of which 97% is on Russian territory. With 4,000 to 4,400 km² of water plane area, it is the largest body of water in northeast China.
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 lake belongs to the Ussuri River System, which is part of Amur River System.
The lake’s average depth is 4.5 m, maximum depth—10.6 m. Its average volume is 18.3 km³, maximum—22.6 km³.
Rainfall mainly occurs in summer, reaching 750 mm annually. Maximum annual temperature is 21.2°C, minimum is −19.2°C. Here, the lake is still covered in ice, although it is gradually cracking. The land around the lake appears mostly thawed, though some snow is visible on the ground to the northwest.
