Largest tributaries
Hulun Lake or Dalai Lake is a large lake in the Inner Mongolia region of northern China.
It is one of the five largest freshwater lakes in all of China, covering approximately 2,339 km2.
In years with high precipitation, the normally exit−less endorheic lake may overflow at its northern shore, and the water will meet the Argun River (Ergune) after about 30 kilometres (19 mi).
The lake is not far from Manzhouli, which is on a major passenger rail-line. Although there are several villages nearby, Manzhouli is the nearest city of notable size. As of 1995 annual fish production was about 7,000 tons, 100 tons of shrimp, 4 kilograms of pearls, 1.5 million crayfish. Hulun Lake is also one of the key reed production areas in China.
Hulun Lake and its wetlands are a Biosphere reserve and a Ramsar site of China.
