Description: China's Water Pollution Prevention Plan for Key Watersheds (2011-2015) covers 10 key watersheds, which then have been divided into 37 control zones and 315 control units to implement the pollution prevention plan. It sets objectives for water quality improvement, control targets of chemical oxygen demand (COD) and ammonia emissions. Moreover, for the Chao Lake Basin, Dianchi Lake Basin, the plan lists control target of the emissions of total nitrogen and total phosphorus.
Outcome:  By 2015, emissions of total nitrogen(TN) and total phosphorus(TP) in Chao Lake Basin will be controlled at 29,000 tons, 2265 tons respectively, which would be reduced by 10.4% and 18%, comparing to the levels in 2010. In Dianchi Lack Basin, the emissions of TN and TP will be controlled at 5200 tons and 346 tons respectively, which would be reduced by 10% and 9.9%, comparing to the levels in 2010.
