(), located in
Jiangxi Province is the largest
Freshwater Lake in
China http://english.people.com.cn/200202/21/eng20020221_90777.shtml ''People's Daily Online'' "Spring Fishing Ban on China's Largest Freshwater Lake".
It has a surface area of 3,585 km&
2 and a volume of 25 km³. Its average depth is 8 meters. The lake provides habitat for a half million migratory birdshttp://www.globalnature.org/docs/02_vorlage.asp?id=15793&sp=E&m1=11089&m2=11093&m3=11178&m4=15621&m5=15793&m6=&domid=1011 Global Nature Fund: "Detailed Data Lake Poyang-hu", and is a favorite destination for
Birding . It is fed by the
Gan and
Xiu rivers, which connect to the
Yangtse through a channel.
During the winter, the lake becomes the home of large numbers of migrating
Siberian Crane s, up to 90% of which winter over there.
There has been a fishing ban in place since 2002.
In 2007 fears were expressed that China's finless porpoise, known locally as the
Jiangzhu or "river pig", a native of the lake, might follow the
Baiji , the
Yangtze river dolphin, into extinction.
Calls have been made for action to be taken to save the porpoise, of which there are about 1,400 left living, with between 700 and 900 in the Yangtze, with about another 500 in Poyang and
Dongting Lakes.
2007 population levels are less than half the 1997 levels, and the population is dropping at a rate of 7.3 per cent per year.
Sand dredging has become a mainstay of local economic development in the last few years, and is an important source of revenue in the region that borders Poyang Lake. But at the same time, high-density dredging projects have been the principal cause of the death of the local wildlife population.
Dredging makes the waters of the lake muddier, and the porpoises cannot see as far as they once could, and have to rely on their highly-developed sonar systems to avoid obstacles look for food. Large ships enter and leave the lake at the rate of two a minute and such a high density of shipping means the porpoises have difficulty hearing their food, and also cannot swim freely from one bank to the other. http://www.chinadialogue.net/article/show/single/en/839-Poyang-Lake-saving-the-finless-porpoise ''www.chinadialogue.net - Poyang Lake saving the finless porpoise
In 1363, the
Battle Of Lake Poyang took place there, and it is claimed to be the
Largest Naval Battle In History .
