Poyang Lake

BW

The Poyang Lake Poyang Hu or ( chinese鄱阳湖, Pinyin Poyang Hu) in the Chinese province of Jiangxi is the largest freshwater lake in China. He is from Gan Jiang, a southern tributary of the Yangtze River, flows through.

The lake is on average 3585 km ² with a volume of 25 km ³. Its average depth is 8 meters. However, the water level fluctuates throughout the year by up to 20 m between the dry season and monsoon. During heavy rainfall events during the heavy monsoon rains it stores as retention basins (similar to the Dongting Lake ), the flood peaks of leading- tributaries and protects through the drain delay, the downstream riparians on the Yangtze River in front of more extreme floods. Dikes occur by backwater especially along the tributaries less strongly fortified, as by the agricultural use of increasingly strong natural floodplains are missing. Overall, secured by dikes storage capacity is about 50 billion cubic meters.

In the dry season its area shrinks to less than 1000 km ² and serves countless water birds as winter quarters.

On it, a decisive naval battle took place which led to the subsequent formation of the Ming Dynasty.
