Taihu Lake is a large lake in the Yangtze Delta plain, on the border of the Jiangsu and Zhejiang provinces. With an area of 2,250 km² and an average depth of 2 metres. It is the third largest freshwater lake in China. The lake houses about 90 islands, ranging in size from a few square meters to several square miles.
Taihu Lake is linked to the renowned Grand Canal. The lake is also the origin for a number of rivers, including Suzhou Creek. In recent years, Taihu Lake has been plagued by pollution as a result of rapid economic growth in the surrounding region.
The lake is also known for its productive fishing industry, and is often occupied by fleets of small private fishing boats. Since the late 1970s, harvesting seafood products such as fish and crabs have been invaluable to people living along the lake and have contributed significantly to the economy of the surrounding area.
