NANJING: The water quality of Taihu Lake has generally improved thanks to pollution control measures over the last two years, Luo Zhijun, governor of Jiangsu, said at the second session of the 11th provincial people's congress last Thursday.

Efforts have been made to treat and cut pollution discharge into the lake, the third largest freshwater lake in China, which has witnessed massive outbreaks of blue-green algae.

One such outbreak disrupted water supplies to one million residents of Wuxi in 2007.
