Lake Tai or
Lake Taihu is a large
freshwater lake in the
Yangtze Delta plain near
Shanghai,
China. The lake belongs to
Jiangsu province and the southern shore forms its border with
Zhejiang. With an area of 2,250 square kilometers and an average depth of 2 meters, it is the third-largest freshwater lake in
China, after
Poyang and
Dongting. The lake houses about 90 islands, ranging in size from a few square meters to several square kilometres. Lake Tai is linked to the renowned
Grand Canal and is the origin of a number of rivers, including
Suzhou Creek. In recent years, Lake Tai has been plagued by pollution as a result of rapid economic growth in the surrounding region.
