Dianshan Lake (simplified Chinese: 淀山湖; traditional Chinese: 澱山湖; pinyin: Diànshān Hú) is a natural freshwater lake, located in the west of Zhu Jiajiao, Qingpu, in the Shanghai municipal area of China, upstream of the Huangpu River. It is the only natural lake in the area. An abbreviation often used for the lake is Dian Lake, which means "sweet water lake".
Shaped like a calabash, the Dianshan Lake covers an area of 63 square kilometers and has an average depth of 2 meters. Connecting with the Huangpu River and the Wusong River, the lake is abundant in aquatic products. The Dianshan Lake gets its name from the Dianshan Hill lying in the middle of the lake. Built on the hill are the Sangu Ancestral Temple and Aofeng Tower. The Dianshan Lake is crystal clear and has the scenery of lush southern-type watery regions.
Some entertainment facilities are built on the east side of the lake, such as water-sports area, yacht club, golf course, fishing club, swimming pool, bowling alley, and shooting range, while on the west side is a juvenile camping base. An international-level resort area named Rainbow Island will be constructed on the south side.
