Largest tributaries
Poyang Lake, located in Jiujiang, is the largest freshwater lake in China.
The lake is fed by the Gan, Xin, and Xiu rivers, which connect to the Yangtze through a channel.
The area of Poyang Lake fluctuates dramatically between the wet and dry seasons, but in recent years the size of the lake has been decreasing overall. In a normal year the area of the lake averages 3,500 square kilometers (1,400 sq mi). In early 2012, drought, sand quarrying, and the practice of storing water at the Three Gorges Dam lowered the area of the lake to about 200 square kilometers (77 sq mi). The lake provides a habitat for half a million migratory birds and is a favorite destination for birding.
During the winter, the lake becomes home to many migrating Siberian cranes, up to 90% of which spend the winter there.
