Diaoshuilou Waterfall, Waterfall in Mudanjiang, China.

The Diaoshuilou Waterfall is located along the Mudan River at the northern edge of Lake Jingpo, measuring about 40 meters across with a vertical drop of about 12 meters. Water flows continuously over the rock ledge, creating a striking visual presence in the surrounding landscape.

The falls lie at the northern end of Lake Jingpo, also called Jingpo Lake Falls, in Ning'an, southwestern Heilongjiang. The lake itself formed when lava from volcanic eruptions blocked the Mudan River; the waterfall spills over that barrier. Its width is usually given as about 40 m, with a 12 m drop, and in the rainy season or floods it divides into two or more channels reaching over 200 m in total width.

The waterfall is also called Jingpo Lake Waterfall, and its plunge pool, 60 metres deep, is named Heilongtan, the Black Dragon Pool. In the rainy season or during floods the fall splits into two or more branches with a combined width of over 200 metres.

The site is accessible year-round, with the strongest water flow during summer months. In winter, water can transform into ice formations that completely change the waterfall's appearance.

The plunge pool beneath the cascade is called Heilong Tan, the Black Dragon Pool, and reaches a depth of 60 metres. In the rainy season or during floods the fall splits into two or more branches whose combined width can exceed 200 metres, far beyond the usual 40-metre span.
