Huating Lake (Chinese: 花亭湖; pinyin: Huātíng Hú), also known as the Hualiangting Reservoir (花凉亭水库 Huāliángtíng Shuĭkù), is a large scale reservoir in Taihu County, Anqing City, Anhui Province, People's Republic of China, used for the purposes of flood control, hydro-electric power generation, agricultural irrigation, transport and tourism. The lake is a National Scenic Area, National 4A Tourist Attraction and demonstration site for agro-tourism.
Damming of the lake to create a reservoir began in 1958 and continued until 1962. There was then an eight-year hiatus until 1970 when construction resumed. Fundamental infrastructure was in place by 1976 and the project completed in 2001.
On October 26, 2009, a 2.1 billion RMB, 23 month reinforcement program began at the reservoir.
