Poyang Lake has never dried up in history.

Poyang Lake has not dried up completely in history, but there have been 2 major droughts. The last drought was between August 2006 and April 2007, when the water surface area was as low as 2886 square kilometers. Recently, due to the low precipitation, the water coming from the upper reaches of Poyang Lake Basin has been reduced, together with the severe high temperature and drought in the upper reaches of the Yangtze River, such as Sichuan and Chongqing, which led to the low water coming from the upper reaches of the Yangtze River during the flood season and the low water level of the Yangtze River, resulting in the water level of Poyang Lake exceeding the lowest level of the same period of time in history for 9 consecutive months.

Poyang Lake, anciently known as Peng Li, Peng Li Ze, Peng Ze, is located in the north of Jiangxi Province, in the cities of Jiujiang, Nanchang and Shangrao, and is one of the five freshwater lakes in China, and also the second largest lake in China, second only to Qinghai Lake. Poyang Lake, one of the major tributaries of the middle and lower reaches of the Yangtze River, is also an overwater, throughput and seasonally important lake in the Yangtze River basin.

Hydrological Characteristics of Poyang Lake

Poyang Lake has become the "catchment basin" of the whole province, and the "transfer station" for the five rivers into the Yangtze River. The hydrological characteristics show that it is a shallow lake with throughput type and seasonality. Seasonal and inter-annual variability of the water level difference between the huge variation remains unchanged, the annual variation in 9.59 ~ 15.36m, the maximum inter-annual variation of 16.69m.

In a year the water level and the lake area varies greatly, such as the 1976 flood Xingzi water level of 21 meters, the lake area of about 3,841 square kilometers, the volume of about 26 billion cubic meters; dry water Xingzi water level of 16 meters, the lake area of about 526 million cubic meters; water level of 16 meters, the lake area of about 526 million cubic meters. 16 meters, the lake area of about 526 square kilometers, the capacity of about only 900 million cubic meters.

"High water is a lake, low water is like a river, flood water is a piece, dry water is a line"", is the natural geographic characteristics of Poyang Lake. Poyang Lake plays a great role in regulating the water level of the Yangtze River, conserving water, improving the local climate and maintaining the ecological balance of the surrounding areas.
