Fuxian Lake 抚仙湖
It is 155 meters deep at its greatest depth， it is also the second deepest fresh water lake in China.
In 2001 it was reported that earthenware and stonework 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.
