Tai (tĪ) [key], lake, c.1,300 sq mi (3,370 sq km), on the border between Jiangsu prov. and Zhejiang prov., E China; second largest freshwater lake in China. Dotted with islands, it is one of China's most scenic areas and was long a tourist attraction, but sightseeing has diminished due to pollution from Wuxi's industries. The lake basin is one of the richest agricultural regions in China; rice, wheat, and cotton are grown. The lake is linked to the Grand Canal.
