Located in Hangzhou City, Zhejiang Province, the West Lake is also known as Qiantanghu Lake in ancient times and as “Xizi Lake” and “Wulin Water” currently. It was formed under the effect of silt deposition in the Qiantang River. The West Lake covers an area of 5.64 square kilometers and has a perimeter as long as approx. 15 kilometers. The lake surface is divided by Gushan Mountain and two artificial causeways (Su Causeway and Bai Causeway) into five sub-lake regions: Inner Lake, Outer Lake, Yuehu Lake, Xili Lake and Xiaonanhu Lake, all being connected by bridges.
