But at low water level (12m), it is only 500km2. According to the hydrological data in 2008, when the water level of the lake is 22.59 meters, the lake area is 4070 square kilometers. Poyang Lake is the largest freshwater lake in China and the second largest lake in China, and China is the second largest lake after Qinghai Lake. Poyang Lake plays a great role in regulating the water level of the Yangtze River, conserving water resources, improving the local climate and maintaining the ecological balance in the surrounding areas.
The name of Dongting Lake began in the Spring and Autumn Period and the Warring States Period, and it was named after Dongting Mountain (now Junshan Mountain) in the lake.

At the end of 1990s, it was estimated by the water conservancy department that there was an area of 2,579.2 square kilometers. However, it also has four major rivers, namely, Xiang, Zi, Yuan and Li, and the flood discharge area of "Four Ports of the Yangtze River" 1.300 square kilometers. The circumference of the lake basin is 803.2 kilometers, with a total volume of 22 billion cubic meters, including 65.438+078 billion cubic meters of natural lakes and 4.2 billion cubic meters of rivers.
Dongting Lake is an important storage lake in the Yangtze River basin, with strong flood storage capacity. It has saved the Yangtze River floods many times, and Jianghan Plain and Wuhan three towns have been able to survive the floods safely.
