geography

course

The Hasselbach rises on the Schälk west of the Iserlohn district of Stübbeken at an altitude of 232.5  m above sea level. NHN in the nature reserve Upper Hasselbachtal .

After a good half a kilometer, the Hasselbach passes the municipality border from Iserlohn to Hagen to the west and also says goodbye to the Märkischer Kreis. Now it flows through the nature reserve Henkhauser- and Hasselbachtal . Further down the stream, it is fed on its left by the Henkhauser Bach and later on the other side by the Galgenbach . It then leaves the nature reserve and shortly afterwards forms a small dammed pond. From here it flows through the Hagen district Hohenlimburg belonging district Henkhausen.

Then the Hasselbach flows through the district of Reh and finally flows out at an altitude of 107  m above sea level. NHN immediately north of the motorway bridge (A 46) coming from the east, turn right into the Lenne approaching from the south-southeast .

The 3.9 km long course of the Hasselbach ends about 125 meters below its source, so it has a mean bed gradient of about 32 ‰.

Tributaries

geology

The Hasselbach runs through the Devonian-Carboniferous border. It is visible on a rocky outcrop in its valley in the form of a thin black layer with a high organic content. It marks a testimony to a mass extinction on earth 358 million years ago. This place was discovered in 1900 by August Denckmann . It was shortlisted as a guiding profile. In competition were the profile La Serre in the Montagne Noire and the profile Nanbiancun in South China. Research opted for the French profile. In 2010 the site was restored and in 2014 a protected, permanent Hagen soil monument as the “area section in the Hasselbachtal at TP 154.4” .
