The Diaoshuilou Falls are situated in the Wanda Shan in the southern part of the Heilongjiang Province. The falls cascades down on the northern side of the Jingpo lake, about 80 kilometres south of Mudanjiang City.
The lake was created by eruptions of the Jingpo volcanic group. It erupted three times in history (12'000 years, 8'300 years and 5'140 years ago). Ejected lava blocked the Mudanjiang ancient river road, formed one of the world largest volcanic lava dammed lake (surface area 95 square kilometres) and left the typical rare remains of a volcanic landscape.
After the completion of hydroelectricity development at the upperstream of Mudanjiang, the falls only appear during the flooding season, when the dam is open to release excess water.
The waterfalls would normally are about 40 metres in width with a drop of 12 metres. In rainy and flood season Diaoshuilou waterfalls become two or multi-stranded water falls, extending to over 200 metres in width.
