East Lake is a large freshwater lake within the city limits of Wuhan, China, the largest[1] or the second largest[2] urban lake in China. Wuhan's East Lake covers an area of 88 square kilometers (33 square kilometers of water area[3]). It is one of the 5A tourist zones of China, and admits over a million people yearly. It is one of the largest sites in Huazhong District. It is also the largest "City Lake" in China. East Lake is made of four areas, Ting Tao, Moshan, Luo Yan Island and Museum of Hubei Province.One end of Moshan features a Daoist temple built over the putative site of where one of the characters in Romance of the Three Kingdoms performed special Qimen Dunjia rites before the famous battle of Red Cliffs. No one knows precisely the actual location, but the Moshan site was an archeological dig in the early part of the twentieth century.
The lake was cut off from the Yangtze River in 1957. Water quality has deteriorated since because of 180,000 tons discharge of wastewater (domestic sewage and industrial) into the lake per day. Each year, about 441 tons of nitrogen and 40 tons of phosphorus flow into the lake. Most parts of the lake have been assessed as eutrophicated, unsuitable for drinking and many recreational purposes.[4]
In clockwise order, starting from the southwest corner:
Several causeways cross the eastern part of the lake, providing access to recreational fishing sites and beaches. In 2012, the construction of a major 6-lane road under the lake (Donghu Tongdao) was started.[7] The Donghu Lake tunnel, China's longest tunnel under a lake, was opened to traffic at the end of 2015. A car could run through the 10.6-kilometer-long tunnel in around 15 minutes.[8]
In 2010, plans for extensive new development on the lake shores caused widespread criticism among the citizenry.[9]
The East Lake has long been used by local fishermen. According to the 1977 statistics, the annual fish yield of the 1500-hectare fishing area of the lake ("The East lake Fish Farm") was 450 kg/ha. The introduction of better fish management techniques have allowed the yields to increase in the following decade, with 1840 tons by 1995.
The main species with which the lake is stocked are the silver carp and the bighead carp.
