The Weschnitz is a 58.9 kilometer long right tributary of the Rhine in the south of Hesse and north of Baden-Württemberg .

River name

The name "Weschnitz" is traced back to Visucius , the name of a Celtic river god. Details are given at the Walpurgis Chapel in Fürth . This chapel stands at a former cult site of the Celts, and ore was mined nearby . Such chapels at old pre-Christian places of worship are not uncommon, one thinks of the Michaeliskapelle on the Heiligenberg near Heidelberg. Large stone crosses in the Odenwald are often an indication of a pagan site, because many menhir were carved into a cross after Christianization.

The Weschnitz is referred to with Wiscoz or similar spellings in numerous documents of the Lorsch Codex as a reference for the location of the Lorsch Monastery .

geography

course

The Weschnitz rises in the Odenwald , in the Hammelbach district of the Grasellenbach community , east of the 536 meter high Wagenberg . Its source is located on a signposted leisure area with a lake and barbecue hut. It first flows a short distance to the village of Weschnitz to the north and then turns along the B 460 in a U-bend to the southwest, breaking for two kilometers in a narrow notch valley between the 399 meter high Krehberg in the south and the 435 meter high Kohlwald in the north through the Tromm- Odenwald to reach Weinheim via Fürth and later along the B 38 via Rimbach , Mörlenbach and Birkenau . Between Fürth and Birkenau the Vordere Odenwald widens to the Weschnitzsenke. The area of ​​the relatively soft and weather- prone granodiorite rock that predominates here has been named Weschnitzpluton after the river . In Weinheim, where the Weschnitz leaves the Odenwald and enters the Upper Rhine Plain, it bends in a new curve towards the northwest. It divides into two arms, the Alte Weschnitz and the Neue Weschnitz and thus forms the approximately 10-kilometer-long Weschnitzinsel , crosses under the B 3 and at Hemsbach the A 5 . It flows on to Lorsch , where its two arms meet again, runs a short distance again along the B 460 and then crosses the B 47 and the A 67 . It then reaches the communities of Einhausen and Biblis , and finally flows into the Rhine near the Biblis nuclear power plant .

The Weschnitz Valley Railway, named after the river, runs in the Odenwald section between Fürth and Weinheim .

Tributaries

From the source to the mouth. In selection, especially from the river division in Weinheim. After this, the branches or the reunited run run to many almost parallel artificial trenches, which are often without proper proper names ("Neugraben", etc.).

history

In ancient times , the Weschnitz in the Hessian Ried used the riverbed of the Ur- Neckar and flowed into the Rhine at Trebur , so much further north than today. Only in historical times did it get the current course by breaking through the dune hills near Lorsch; therefore it is canalised in the area of ​​the Upper Rhine Plain ( Bergstrasse district ). The current Weschnitzlauf can be proven from the middle of the 17th century, previously the Weschnitz probably ran south of Lorsch, where it fed the Lorsch lake (at today's Seehof residential area ). Its mouth was up the Rhine from the late antique Rhine port of Zullestein , which therefore only lies on the Weschnitz after the castle was abandoned. Therefore it is never mentioned in historical sources as lying on the Weschnitz. The stream flowing there was called "Steiner Bach".

It is wrong to believe that the stone products from Felsberg and Auerbach were transported over the Weschnitz to the Rhine. Before the Tullas straightening at the mouth of the Weschnitz, the Rhine itself was not deep enough to B. to carry barges with the large granite pillars from Felsberg.

After the great floods with dam breaks in 1882/83, 1922 and 1955 at Weschnitz and Winkelbach , the Weschnitz Association was founded in 1958. As early as 1956, at the instigation of the Hessian state government, all drafts for a regulated flood discharge were compiled, first the Weschnitz and then the Lauter and Winkelbach. Between 1958 and 1970 a bundle of construction measures was carried out under the sponsorship of the Weschnitz Association. This ranged from dam elevations to the construction of six flood retention basins, five of them in the Odenwald and one in the reed. From the two water regulation associations Weschnitz and Lauter-Winkelbach emerged on January 1, 2001 the "Gewässerverband Bergstrasse". To protect the curlew was nature reserve Weschnitzinsel reported 1979th

In 2006/2007, the Weschnitzgraben was redesigned in the area of ​​Einhausen. They left it with the previously deepened creek bed and the existing creek, but widened it a little and placed larger boulders as obstacles in the creek's path. Dams were also partially replanted to beautify the watercourse and its immediate surroundings. The intention with these changes was not so much to restore the stream to its original shape as to create an experience space in it, which is why the river bank was made accessible in some places. Since then, children can be seen playing by the water in summer.

View of the renatured area of ​​the Weschnitz below the Wattenheim bridge

In March 2007, the city of Lorsch began to renature the Weschnitz in the area below the Wattenheimer Bridge . Around 30,000 cubic meters of earth were moved for this purpose. The northern Weschnitz dam was dismantled so that a biotope could form. The renaturation, the cost of which was 470,000 euros, was done to compensate for the development of the Lorsch industrial area "Daubhart". The Weschnitz was given significantly more space to create meanders . Spawning sites have been created for the nasal fish that have settled there. Black poplars were replanted on the river bank . Archaeologists accompanied the construction work around the Wattenheim Bridge. They hoped for finds from the Celtic era, such as pottery shards and the remains of spearheads.

The water quality of the Weschnitz has improved noticeably in recent years. In the meantime, water quality has almost been achieved at the Wattenheimer Bridge.
