The Eulach is an approximately 20 kilometer long tributary of the Töss .

geography

course

The Eulach rises north of the Schauenberg in the municipality of Hofstetten (ZH) under the name Farenbach and initially runs approximately northwards, after about five kilometers it turns into a now broad valley and under the name Eulach bei Elgg on the west course, it flows after crossing the city Winterthur in its urban district of Wülflingen from the right into the lower Töss . The modest body of water played an important role as a source of energy in the industrialization of the city.

The area between Elgg and Winterthur is called Eulachtal after the river . Winterthur is sometimes referred to as Eulachstadt . Before the dipping into the old town area from the vocational school to the Sulzer high-rise , with a small opening at Neumarkt on Technikumstrasse, the river ran around the medieval city on the Technikum side. The city center of Winterthur is passed underground by the river at 650 meters. The Eulach still serves to relieve the flood of the urban sewerage system when there is heavy rainfall.

history

It can be assumed that the Eulach was of decisive importance for the founding of the city of Winterthur, as the river flowed around the city limits at that time. From the Middle Ages to industrialization, the Eulach's hydropower was an important asset; by diverting a stream in the Waltsental, its water flow was increased early on. The right to use the Eulach water in Winterthur was first confirmed in a document in 1180 by the Kyburgers , and in 1433 it was confirmed in writing by Emperor Sigismund , after the Töss monastery had requested the demolition of all mills built from 1415 three years earlier . From the second half of the 12th century to 1835 the Rettenbach was branched off from the Eulach , which supplied Winterthur with process water and was used for waste disposal. In the old town alone, six mills used the river's hydropower. The Eulach was owned by the city of Winterthur for over 400 years, in 1895 it became a public body of water and its use was now regulated by state concessions.

In the 19th and 20th In the 19th century, the city's settlement pressure increased , which is why several reed areas around the Eulach were drained and river arms were filled in. In 1911/12 the Eulach was then dumped in the area of ​​the Altstadt / Neuwiesen districts , so that today it can only be seen through a small viewing window in the city center. There were further corrections in the years 1952–1960 and 1968–1975.

  • The Eulachwuhr on Bahnhofplatz before it was overturned, around 1905

  • Open Eulach along Eulachstrasse (today Technikumstrasse), around 1910

  • The Eulach is dipped in the area of ​​today's Sulzer high-rise, 1912

  • The Eulach encroaching near the Wuhr, view towards Bahnhofplatz, 1911

etymology

The etymological origin of the Eulach is controversial. Conceivable is a derivation from the Old High German word Ache . Name forms such as Oillach, Oülach, Ouwlach or Oͤllach are documented in the Middle Ages. A Celtic or Germanic origin of the name is conceivable. It is assumed that the name was previously based on the village of Elgg .

Namesake

After the Eulach are named or were in Winterthur: the Eulachhalle , the former Winterthur radio station Radio Eulach (predecessor of today's Radio Top ), the Eulach Squash Club Winterthur , the tennis club TC Eulach, the former floorball club UHC Winterthur-Eulach , the Eulach brass band Musicians and the Eulachpark in the Hegi district , where the river bed was renatured and made accessible in 2010.
