The Fuxian Lake stretches in the Chengjiang County, Jiangchuan County and Huaning County in Yunnan Province, about 60 kilometers to Kunming City. Covering an area of 212 square kilometers, the Fuxian Lake is ranked as the third largest lake in Yunnan, right after the Dianchi Lake and the Erhai Lake. As the deepest lake in Yunnan, it is 155 meters deep at the biggest depth. It is also the second deepest freshwater lake in China after the Tianchi Lake, a volcanic-vent lake lying in Changbai Mountain in Northeast China. The water storage of the Fuxian Lake is four times greater than the total storage of the Dianchi Lake and the Erhai Lake.    

Once in the southwest of the Fuxian Lake were two islands, Big Solitary Island and Small Solitary Island. The Big Solitary Island is 40 meters higher than the lake and has an oval shape, like an egg. Covering an area of 0.5 square kilometers, the lake has many grottos and peaks. It also has many broken rocks on the side that faces water. The Solitary Mountain Scenic Area was named a provincial scenic spot of Yunnan Province in 1998, and later was listed as the first Sleepless Island by the provincial government of Yunnan.     

The Fuxian Lake has a great content of phosphorus. As a non-contaminated lake, its water appears clear blue and has a visibility of 7 to 8 meters. Its beach is clean with fine and soft sand. Since the water temperature does not change with seasons and the water is of high quality, the Fuxian Lake is a perfect swimming place, especially the area along the northern Chenjiang Dam. About 200 meters along the shore, the limpid water is 1 to 3 meters in depth with silver sand stretching for several meters to the shore at the bottom, attracting thousands of tourists to swim here every year. Many tour facilities have been built in the Fuxian Lake and on the mid-lake islands, making the lake an ideal summer resort.     

With fertile soil, the Fuxian Lake valley is abundant in local products, such as rice, wheat, horsebean, flue-cured tobacco, and cole. It is a famous barn in Yunnan Province, and also a famed land flourishing with flue-cured tobacco.
