Poyang Lake (China)

Poyang Lake is the largest freshwater lake in China. Located within Jiujiang Prefecture in Jiangxi Province, it is fed by the Gan, Xin, and Xiu rivers and flows northward into the Yangtze River 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 this critically endangered species spend the winter there.
