Diemeltal between Trendelburg and Wülmersen
The Diemel is a 110.5 km long, western and orographic left tributary of the Weser river in Hesse and North Rhine -Westphalia ( Germany ). She is the first, so southernmost of the larger Weser flows to the emergence of the same by the confluence of the Fulda and Werra.
In historical sources, the Diemel is also mentioned as Dimel, Dymel, DiMella, Dimola and Timella. According to F. Witt and Ludwig Schneider, the old Saxon adjective " THIMM " is for " dark " is the origin of the name Diemel. Namensähnlickeiten in field names can be found for Melbeck in the Lüneburg Heath.
The Diemel rises in the northwestern part of Hessen only about 300 m north of the border with North Rhine -Westphalia in the northeast part of the Rothaargebirge. Your source " Diemel source ", located at the junction of the mountain regions and Upland Sauerland, the northeastern foothills of the Rhenish Slate Mountains are. It is located on the southern edge of the nature park Diemelsee nearly 2.5 km south- southwest of Usseln (village of Willingen ). At about 660 m above sea level. NHN height they entfließt the northeast slope of the 738 m high mountain Auf'm Knoll in the west or the north- western slope of 775.3 m high mountain Kahle Pön in the east.
Watershed: The source area of the Diemel is on the Diemel-Eder/Fulda/Weser-Wasserscheide. This means that the current flowing to the northeast Diemel drained directly into the Weser, while the waters of the south of the mountain springing streams a southerly detour via the Wild Aa (from the middle reaches Aar called ) which at a few kilometers south-west to Krutenberg springs and there flows in an easterly direction, make the Weser Orke, Eder and Fulda.
The source of the Diemel is but - contrary to other statements - not on the Rhine -Weser watershed because it extends slightly further to the southwest via the hopper head and there bends to the Hille - Ruhr and head south.
From its source the Diemel flows in the northwestern part of Hesse in the Waldeck -Frankenberg first gently downhill to Usseln and then northward lie by a beautiful valley in which three villages: Hemmighausen (village of Willingen ) Deisfeld and Giebringhausen (municipality parts Diemelsee). Then her water reaches from the south the Diemelsee, in the discharges match that of the west flowing Itter. Just before the dam, the Diemeltalsperre passes through this reservoir the limit of the above-mentioned states, so that the flow from now flows in North Rhine -Westphalia in Hochsauerlandkreis.
Below the dam, and thus from Helminghausen (not to be confused with Hemmighausen ) flows through the Diemel in a northeasterly direction a beautiful valley, was in the planned times (or still is? ) To build another dam (which, for example, in numerous maps is recorded ) and in which one believes to be in an alpine landscape. Up to 595 m high mountains perched there majestically above the valley where there are no other villages except Helminghausen, up to Padberg and Giershagen, both located on a mountain above the Diemel. In this valley the Diemel is first fed by the coming from the south Rhene and then by the current flowing from the west approach Hopp corner. Then the Diemel leaves the Diemelsee Nature Park, being the southeast on Sintfeld flows past and passes through Mars mountain to West home, where they partly runs along the border of the aforementioned states and reaches the location of this boundary in Hesse community Diemelstadt. After passing under the A44 ( Diemel Viaduct, 100 meters long) it flows through the district Wrexen, opens at the northeastern outskirts of the village coming from the south Orpe. North of this village are the southernmost foothills of the Eggegebirge that forms the southern part of the Teutoburg Forest Nature Park / Eggegebirge, the southern limit of the Diemeltal is.
Then the Diemel enters increasingly widely expectant landscape after North Rhine -Westphalia and thus in the county Hoexter. In it she runs through the Warburg flange where it close to the south the ruins of the castle Desenberg happened and it will flow coming from the south Twiste in Warburg. A little further down the river, they again reached the border of the two states, opens at the hiesig comes from the north Eggel, and then goes directly to the north of Hesse, and thus in the district of Kassel. Immediately below Liebenaus opens a coming from the south Warm. After that rises right hand of Hofgeismarer city forest.
Then the Diemel runs through Trendelburg where the castle stands Trendelburg and accrues at her Wülmersen district coming from the southeast Holzape. After flowing through a beautiful valley again on the northwestern edge of the Reinhard Forest, where the Sababurg is, it reaches Helmarshausen with the Krukenburg.
After the last loop of the river which flows Diemel slightly northwest of Helmarshausen in Bad Karl Harbour at the Weser 44.68 kilometers directly below the Hessian cliffs at about 95.6 m height in the upper Weser. Thus arise between source and mouth of about 564.4 m height difference.

Geologically the Diemel is located in a 240 million year old river landscape. The source region is located in the Rhenish Slate Mountains, and is the time from Devon and carbon assigned.
Early documentary mention as Timella found 797 to a camp of Charlemagne ( Karolus ) at Herstelle. On 16-17. July 1965 directed the Henry Flood, in which all known water levels have been exceeded, the entire Diemeltal very serious damage to.
Dams and power plant
The catchment area of the Diemel include a total of three dams:
- Dam Schmala at the Schmala, Hochsauerlandkreis, North Rhine -Westphalia
- Diemelsee at the Diemel, Waldeck- Frankenberg / Hochsauerlandkreis, Hesse / Rhine- Westphalia
- Twistesee at the Twiste, Waldeck- Frankenberg, Hesse
About 300 m north-northwest of Wülmersen, not far east of the B 83 and close to the dead-end access road after Wülmersen stands besides a dam to supply the power plant the Diemel power plant Wülmersen, which is since 1921 in operation and with its three turbines approximately 565 KW power generated.
Navigability and water
The section Stammen (before Trendelburg ) to Bad Karl port was from 1710 to 1723 through expansion, accompanying canals and locks made navigable and was part of the planned from the river Lahn to the Weser but never completed Landgrave Carl- channel.
In the middle reaches of the Diemel the navigability of the water output of the power station of Diemeltalsperre depends, so that the section of the river with kayaks at 3 to 4 m / s is passable.
The underflow from the Diemel Warburg is used throughout the year for recreational craft ( kayak and Canadians ) and a worthwhile destination for canoeists. Some weirs are difficult to portage. On Diemel power plant Wülmersen the Hofgut Wülmersen a Umtragungsweg is created. There are boat rentals and guided canoe trips. On May 1st of 2007, for the Hessian underflow between Haueda and Bad Karlshafen new Befahrung rules in force. Private boaters are subject to quotas since then and have to sign for example via the Internet for the Kassel. Prerequisite for motor vehicles is a water level in Helmarshausen of 173 cm. This correlates with the red-green- water level indicators to the access points ( Befahrung only with " green ").
The Waterways and Shipping Office Hann. Munden operates several levels for detecting the water level and the inflows and outflows of Diemel dam. The water levels are accessible online and is recorded for the following locations:
- The influx of Diemel is measured by the level Wilhelmsbrücke.
- The influx of Itter is measured by the level Kotthausen.
- The water storage level of the dam Diemel is measured by the level Diemeltalsperre.
- The drain in the Diemel is determined by the level Helminghausen.
In the lower reaches of the Diemel no further officially accessible water levels are determined; from the difference of the water levels of Karl harbor and Wahmbeck conclusions on the contribution of Diemel for water supply from the Weser to be determined.
Interestingly, upstream of the Diemel is that it is up to its confluence with the Diemelsee much shorter than Itter and Hopp corner ( the most significant inflows in Diemel headwaters ), with its spring-fed streams, so that especially the Hopp corner - if one forth of the length considered - the actual Diemel source flux.
One of the towns on the Diemel include ( downriver seen ):
- Mars mountain
- Bad Karlshafen
Attractions and sights directly on or near the Diemel are the Diemelsee, the ruins of the castle Desenberg that Trendelburg, the cloudbursts in Trendelburg, the moated castle Wülmersen, the former Benedictine monastery in Helmarshausen, the ruins of the Krukenburg and the baroque town of Bad Karl harbor.
Along the Diemel leads - from the source to the mouth - the Diemel cycle path.
