Elsebach

Elsebach (in its upper course, upstream from the Lollenbach, also: Reingser Bach) is a small river of North Rhine-Westphalia, Germany. Its source is north of Oestrich (a district of Iserlohn). Near Reingsen, it is joined by its left tributary Lollenbach. It empties into the Ruhr near Schwerte.

The open air bath "Elsebad" is named after the creek which was used in the past to provide water for the bath.
