The Lenne is a tributary of the river Ruhr in the Sauerland hills, western Germany. It has caused flooding in recent years.^[2]

Having its source on top of the Kahler Asten near Winterberg in an intermittent spring at an elevation of 2,687 ft (819 m), the Lenne ends after a course of 129 km flowing into the Ruhr river near the city of Hagen. With an average discharge of 25 m³/s near its mouth, it is the main tributary of the Ruhr. ^{[citation needed]}
