What are the three major freshwater lakes in China?

Poyang Lake is the largest freshwater lake in China. When the flood level is 2 1.69m, the lake length 170.0km, the average width 17.3km, and the rainy season area is 39 14km. The maximum water depth is 29.19m, the average water depth is 5. 1 m, and the water storage capacity is149.6x108m3.

2. Dongting Lake

Dongting Lake is the second largest freshwater lake in China. The dry season covers an area of about 2625km? The flood season is more than 3,900 square kilometers, and the total area of the lake area is18,000 km? . Volume120 billion cubic meters. The main rivers entering the lake are Xiangjiang, Zishui, Shui Yuan and Lishui. It spans Hunan and Hubei provinces, connecting the Yangtze River in the north and the four waters of Hunan, Guizhou, Yuan and Tan in the south, and is known as the "Eight Hundred Miles Dongting Lake".

3. Taihu Lake

Taihu Lake is the third largest freshwater lake in China. Located at the junction of Jiangsu Province and Zhejiang Province, in the south of the Yangtze River Delta. About 6.5438 million years ago, Taihu Lake was still a big bay, but it was gradually isolated from the sea in the process of seawater desalination and became an inland lake.

Extended data:

The largest freshwater lake in the world is Lake Superior, and the largest freshwater quantity is Lake Baikal. The largest freshwater lake in China is Poyang Lake (39 14km? ), followed by Dongting Lake (2625km? ), Taihu Lake (2338. 1km? ), Hongze Lake (2069km? ), Hulun Lake (2043km? ), Chaohu Lake (769.5km? ), gaoyou lake (760.67km? )。

Danjiangkou Reservoir is the largest artificial freshwater lake in Asia and the core water source of the Middle Route Project of South-to-North Water Transfer in China.

Freshwater lakes are divided into closed and open types:

Closed freshwater lakes are mostly located in high mountains or inland areas, and there are no obvious rivers flowing in and out.

An open freshwater lake may be quite large, with islands and many rivers flowing in and out. Freshwater lakes are generally outflow lakes; Because the water source can be renewed and replenished, the salt content of freshwater lake is very low.
