The Möhne is a 65.1 km long, eastern and orographically right tributary of the Ruhr in the Hochsauerlandkreis and Kreis Soest in North Rhine-Westphalia ( Germany ).
course
The Möhne rises in the Hochsauerlandkreis on the southern edge of the extensive Brilon plateau about 2 km south-southeast of the city center of Brilon . The source is located on the eastern slope of the Poppenberg at about 545 m above sea level. NHN in the Gewann Helle , the so-called "Little Switzerland". South of the source is the Poppenberg holiday complex and beyond it the Gudenhagen-Petersborn district . To the east runs a section of the federal highway 251 , which leads from Brilon south to Willingen . A section of the Rothaarsteig , a long-distance hiking trail from Brilon to Dillenburg that runs mainly on the main ridge of the Rothaargebirge , passes the source at a former ski jump slightly below it . The Möhnetal Cycle Path runs almost the entire length of the river.
Part of the Möhne initially flows above ground through the spa gardens as a "Hunderbecke", with the stream bed concreted in and temporarily drying out, while another part flows through the sewer system. At the sewage treatment plant on the Ostring in the northern part of Brilon, the Möhne reappears as a "Hunderbecke" and flows north along the B 480 . From the inflow of the Aa ( Möhne origin) it is then called Möhne.
A little further north-northwest the Möhne passes the bit off or east, and at the same time located above the flow Briloner district Wülfte , wherein at the local Osterhof the light coming from the southwest Goldbach opens. From the subsequent junction of the B 516 from the B 480, it turns a little more to the north-west.
Then the Möhne crosses the border to the Soest district, its valley being bordered to the northeast by the southwestern foothills of the Sintfeld . From Rüthen , which it touches to the south and after which the Glenne joins as the longest Möhne tributary, the Möhne runs between the Haarstrang in the north and the Upper Arnsberg Forest in the south.
The Möhne reaches the district of the town of Warstein , where it first flows through the Belecke district , where the Wester flows in from the south as the second longest Möhne tributary. Then it flows through the districts of Mülheim and Sichtigvor . Thereupon the river crosses Allagen , from where it runs in a westerly direction between the Haarstrang in the north and the Lower Arnsberg Forest in the south. In doing so, it passes the Allagener locality Westendorf located north of the river and then flows through Niederbergheim with the locality Oberbergheim located slightly north of the river ; at Niederbergheim the B 516 leaves the river northwest.
According to this, the Möhne runs in the municipality of Möhnesee through the district Völlinghausen , where it flows into the eastern part of the 10.37 km² Möhnesees ( 213.7 m ). As it flows through the reservoir, the river, which continues to strive westwards, passes the districts of Wamel , Stockum , Körbecke , Südrandweg and Delecke , where the still water is bridged by the B 229 . The third longest Möhne tributary flows into the Hevesee pre- dam and then into the Hevearm of the Möhnsee, coming from the east-southeast, the Heve . The Möhne leaves the lake through the “Möhne dam” located between Günne in the north and Brüningsen in the south.
Below this dam, the Möhne reaches the municipality of Ense , a little after flowing through the compensation basin , in which it runs southwards. From then on it flows between the Haarstrang in the west and the Lower Arnsberg Forest in the east. It touches the district of Niederense to the south-east, only to flow through the small Enser See ( 162.5 m ) below the district of Steetsberg , which it passes to the west, and then to run again in the Hochsauerlandkreis.
The Möhne then reaches the north-western Arnsberg district of Neheim-Hüsten and then its district of Moosfelde . It then crosses under the federal motorway 46 between the districts of Totenberg in the north and Binnerfeld in the south . Immediately to the west of the Neheim junction , the Möhne finally flows from the east at around 153 m into the Ruhr flowing there from the south .
Dispute about Möhnequelle
In 1971, after heated discussions, the location of the Möhne spring was determined to be above the Brilon spa gardens. Nevertheless, the districts of Altenbüren , Gudenhagen-Petersborn and Scharfenberg also “claim” the location of the river's origin.
The following information can be found in the German Basic Map (DGK): The Möhne spring was drawn in near the Poppenberg south of Brilon at DGK5 4617/8. On the DGK5 4517/23 the Möhne does not begin until after the confluence of Hunderbecke and Aa . The union of both rivers is scientifically called Möhne origin . As a result, the Möhne spring drawn is the source of the Hunderbecke.
Before the Brilon spa park was created, the Hunderbecke flowed through a swamp area. Today it preserves and channels a concrete channel and prevents premature seepage. The Aa also flows through the Brilon plateau . In the mass limestone of this ridge, most of the streams disappear in stream shrinkages or swallow holes in the subsoil. However, many of these stream shrinkages were backfilled by farmers so that the water from the Aa and Hunderbecke no longer completely disappears into the ground and their stream beds no longer dry out.
In earlier times, the Möhne only flowed through all year round from the confluence of the Goldbach , which is why the Möhne spring was marked on old maps with the highest spring in the Goldbach headwaters below the 553 m high mountain Sonder near Scharfenberg. Thus the Scharfenberg claim would be justified from a historical and “water-bearing” point of view. Citizens of Altenbüren see themselves at the source of the Aa, and if the Möhne spring were there, the Möhne would be longer than over the source rivers Hunderbecke or Goldbach. Now, at the latest, an objection is being raised in Petersborn, because the Hilbringsen Aa inflow is even longer, but also disappeared earlier in the mass limestone.
Regardless of the discussion as to which source river is the most important source river of the Möhne, the Möhne rises near Brilon. Their source rivers are called Goldbach, Aa and Hunderbecke.
Spring streams, tributaries and reservoirs
Spring streams
The rivers, historically considered as Möhne source brooks, include these ( the origin of the Möhne river is at the confluence of the Hunderbecke and Aa mentioned below ; Aa and Goldbach can also be viewed as tributaries):
- Hunderbecke ( coming from the Möhne spring below the Poppenberg ; flowing to the Möhne origin )
- Aa (confluence at the Möhne origin ; 800 m north of the edge of the Brilon core city at "Five Bridges")
- Goldbach (confluence between Brilon and Wülfte am Osterhof)
Catchment area and tributaries
The catchment area of the Möhne is 468.579 km². The most important Möhne tributary is the Heve , which flows into the Hevesee pre- dam and then into the Hevearm of the Möhnsee. With a catchment area of 91.127 km², it has a share of around 20% of that of the Möhne. Other important tributaries are Glenne and Wester .

Reservoirs
The Möhne is dammed between Völlinghausen and Günne in the Möhnesee ( 213.7 m ). The barrier is at stationing kilometer 12.15. The lake behind it stretches for 10.4 km and ends at stationing km 22.5. Below the barrier wall is the compensation basin ( called compensation pond) of the dam between stationing kilometers 11.4 and 12.15.
Below Steetsberg, the Möhne is dammed again between the stationing kilometers 4.45 and 5.15 by the Enser See ( 162.5 m ).
Water management
The Möhne is of particular importance for the production of drinking water, especially for the Ruhr area. Via the Möhnestausee and other reservoirs in the Ruhr catchment area, the water level in the Ruhr can be regulated in such a way that around 2.2 million people in the largest conurbation in North Rhine-Westphalia can be evenly supplied with water. However, the illegal spreading of sewage sludge by farmers in the Möhne catchment area has permanently polluted the river's water with perfluorinated surfactants (PFT). In the summer of 2006, increased concentrations of perfluorinated surfactants were detected in the water of the Rhine below the mouth of the Ruhr. The contamination could be traced as far as the Möhne. As a result, the concentration of the substance considered carcinogenic in the river system of the Ruhr must be reduced by water from reservoirs other than the Möhnesee to such an extent that they are considered harmless. After a partial renovation of contaminated arable land in Brilon-Scharfenberg in 2007, another contaminated field in Rüthen was to be extensively renovated in 2008 in order to further reduce the pollution of the water.
