The Hanfbach is a left tributary of the Sieg . It rises in Rhineland-Palatinate about 800 meters northwest of the village of Griesenbach at about 273 m above sea level. NHN as Irmerother Bach . Near the village of Buchholz -Mendt it unites with the Mendter Bach and from here bears the name Hanfbach . It flows into Hennef at a height of 66 m . Its length is over 19 km, of which 13.6 km flow into North Rhine-Westphalia . The Hanfbach flows through the Hanfbach nature reserve and tributaries .
Even if the stream used to drive the so-called hemp mill, the name has nothing to do with hemp or hemp cultivation in this area. Researchers assume that the name was derived via hanapha (hanafa) from the Germanic hanan (singing, sounding) and apa (river, water), which could have meant something like sounding river . Indeed, when it rains heavily, the Hanfbach turns into a torrential body of water and the difference in altitude from the source to the mouth is also quite considerable at approx. 207 m over 13 km.
In addition, the name of the city of Hennef is derived from this brook. The place used to be called Hannafo .
