Fuxian Lake (Chinese: 抚仙湖; pinyin: Fǔxiān Hú) stretches out through Chengjiang County, Jiangchuan County and Huaning County in Yunnan Province, spanning an area of 212 square kilometers. The lake is ranked third largest in Yunnan, after the Dianchi Lake and the Erhai Lake. Also the deepest lake in Yunnan, it is 155 meters deep at its greatest depth. It is also the third deepest fresh water lake in China after Tianchi Lake and Kanas Lake.[1]
Flora and fauna
Fuxian Lake is known for its unique fauna, including many endemic species. However, its relative isolation makes it vulnerable to biological invasions and pollution.[2][3]
In total, there are 25 native fish species in the lake, including 12 endemics.[4] Situation for many of these is precarious because they have been negatively impacted by introduction of exotic species of fish, habitat degradation, water pollution, and overfishing. The table below lists endemic species, all cyprinids, that have declined strongly; some of them may already be extinct.
A fungus Dyrithiopsis lakefuxianensis growing on submerged wood has been collected and described as a new species to science from Fuxian Lake, as suggested by its scientific name.[5]
Lost city
In 2001 it was reported that earthenware and stonework covering an area of approximately 2.4-2.7 square kilometres had been discovered beneath the lake. Carbon dating circa 2007 confirmed an age of 1750 years, or approximately 257AD. It is thought that the remains may represent buildings from the ancient Dian Kingdom that slid in to the lake during an earthquake.[6][7]
Notable Sites
West
There are two major sites on the west of the lake, a military base at Lijiashan (speculated to be used for submarine testing and other forms of nautical engineering), and a tourism resort nearby.
