Today the Dühnn is a brook that meanders romantically through the Dühnntal. It used to be a thundering (hence the name Dühnn -> thunder) in the rainy season, which led to severe devastation in the valley. Today the Dühntalsperre regulates the water flow.

The Dhünn is a 40.02 km long, orographically left and south tributary of the Wupper. It rises in the Bergisches Land and flows into Leverkusen in the Wupper, immediately before it even flows into the Rhine. It is the longest tributary of the Wupper and flows through the Oberbergischer Kreis, the Rheinisch-Bergischer Kreis and the independent city of Leverkusen. In April 2010, the Dhünn was declared the first "barrier-free river" in North Rhine-Westphalia.
