Taihu Lake, Suzhou

Taihu Lake is a large lake in the Yangtze Delta plain, on the border of the Jiangsu and Zhejiang provinces in the People's Republic of China. The waters of the lake belong to the former in its entirety with part of its southern shore forming the boundary between the two provinces. With an area of 2,250 km² and an average depth of 2 metres, it is the third largest freshwater lake in China, after the Poyang and Dongting Lakes. 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.
