Mudanjiang Jingpo Lake

Lake Jingpo or Lake Jingbo, literally "Mirror Lake", is a lake scenic area located on the Wanda Mountains, in Ningan County of Mudanjiang city, northeast China's Heilongjiang Province, in the upper reaches of Mudan River. Earlier names for Lake Jingpo include Meituohu Lake, Huhanhai Lake and Bi'erteng Lake.

The length of the lake from north to south is 45 kilometres (28 mi) and the widest distance between east and west is only 6 kilometres (3.7 mi). The area is 95 square kilometres (37 sq mi) and the storage capacity is 1.63 billion m3. The south part of lake is shallow with the deepest place in the northern part at 62 metres (203 ft).

The lake was created about 10,000 years ago when volcanic eruptions in the region blocked the flow of the Mudanjiang River. The northern side of the river cascades down the Diaoshuilou Falls, a 40 m (131 ft) waterfall formed by the lake. This lake is famous for its craggy limestone cliffs (similar to those of Guilin) and its turquoise waters containing 40 types of fish and fresh water coral. On Titan, the largest moon of the planet Saturn, there is a large surface body of liquid hydrocarbons, Jingpo Lacus, named after Jingpo Lake.
