. Yangzonghai Lake is noted for its underwater springs and is one of several scenic areas in Yunnan province, which is known for its biodiversity. The lake is a popular resort destination for people living in the nearby provincial capital of Kunming, which itself borders Dianchi Lake, one of China's biggest freshwater lakes but also one of its most polluted.

Pollution

As recently as 2002, Yangzonghai had been noted for having water clean enough for drinking and swimming. But as of September 2008, it was officially considered unfit for drinking, swimming in or fishing in, when the provincial government announced high levels of arsenic

Cleanup project

The Yunnan provincial government has initiated the "China Yunnan Yangzonghai Lake Water Pollution Reduction, Arsenic Removal and Water Quality Restoration" project in a bid to clean up the lake via the Yunnan Provincial Scientific and Technological Development Research Institute. The main objective of the project will be to reduce the amount of arsenic in Yangzonghai's waters from the current 0.128 grams/liter to 0.050 grams/liter within a three-year period.
