Shrivelling Poyang Lake

Poyang Lake, China's largest freshwater lake, is now one-twentieth of its former size.

When this Bystander last checked on Poyang Lake, China’s largest freshwater lake, in September it was recovering from the severe spring drought that had shrunk it to 400 sq. kms, barely a third of its average size over the past decade. That replenishment has not only stopped. It has been dramatically reversed, as the picture above, published earlier this week by state media and reportedly taken on Tuesday, and the one below, taken in November, show. Jiangxi’s provincial hydrographic bureau says the lake’s surface area is now less than 188 sq. kms, about 5% of its former size. At full capacity, it is as large as 4,500 sq. kms, or  more than six times the size of Singapore.

The lake is fed by five rivers in Jiangxi and empties into the Yangtze. Its water level has fallen so far that fishing is possible for barely three months of the year. The lake used to provide a livelihood for a fleet of 10,00 fishing boats, as well as being home to a rare finless porpoise. It also supports hundreds of thousands of migratory birds including the Siberian crane in winter, that, like the fishermen, depend on a lake full of fish to survive. The lake’s nature reserve authority is planning to stock the lake again to help both groups, though last year’s restocking failed as so many of the fry perished for lack of water. In November, the birds had to have food brought in.

Lack of rain this year is being blamed for Poyang’s shrivelling, but it is far from the only lake in China to be drying up. Nor is drought the sole reason.
