Chenghai Lake is a mesotrophic[1] plateau lake in Yunnan Province, China. The lake has a total area of about . The average depth is, with an elevation of . the water storage capacity is about 19.87×108m3.[2] Chenghai Lake is one of only three lakes in the world where Spirulina is found naturally.

Ecology

Chenghai Lake is known to have significant yeast biodiversity; a study collected and identified 64 yeast strains, in 22 species across 8 genera.[3] The lake is a closed ecosystem, and is mesotrophic, meaning it supports an intermediate level of biological productivity.[4] Aquatic vegetation in the lake has declined, probably due to pollution, habitat destruction, eutrophication, and effects of grass carp stocks.[5]

Pollution

Caesium-137, a radioactive fallout isotope, is present in the lake.[6]
