The Welser Mühlbach is a former tributary of the Traun (which in the area of the city of Wels used to split into several branches). Since the stream was provided with an inflow weir and in the urban area of Wels with bank reinforcement, it looks like an artificially created stream . It flows on the left bank of the Traun through the Welser Heide . In Au an der Traun in the municipality of Gunskirchen , it is derived from the Traun and flows back into it in the urban area of Linz . The Mühlbach in its current form is likely to have been used as a Mühlbach from the beginning of the Middle Ages, but it had been used as a drinking water supplier for the old town for a long time (until house wells were built). Its length is about 30 km.
course
The Mühlbach branches off from the Traun in front of the Traun weir of today's Breitenbach power plant in the Gunskirchner district of Au and flows essentially in a north-east direction parallel to the Traun through the Wels district of Lichtenegg , into the Wels city center , where it joins the Traungasse about halfway between the town square and the old one iron Traunbrücke, then on through the Pernau , where it used to feed the Wels paper mill . From there it flows northeast of the Wels industrial area through Wels sheep meadows and finally reaches Marchtrenk , where it flows through the districts of Schafwiesen, Au , Kappern and Leithen . At Holzleiten it reaches the municipality border to Hörsching , it flows through the villages of Rudelsdorf, Rutzing and Frindorf. East of Frindorf it runs through the Oedt district of Traun and south of the inner city of Traun to St. Martin and Linz- Kleinmünchen , where it flows into the northern Kleinmünchner Canal (factory canal).
Side arms
In the inner city of Wels, two branches of the Mühlbach stream branch off; the first is used to irrigate the Wels zoo ; it is diverted with the help of a bucket wheel . The second branches off from the Mühlbach at Schwimmschulgasse 13 and reunites with it at the Wels water tower. Some houses in the area from Pollheimerstraße to Villa Muthesius (museum of traces of life) are almost on a 250 m long island.
In the east of the city center, the Schenkelbach branches off to the right from the Mühlbach, west of the waste incineration in the Pernau district , the Schiffermüllerbach is diverted. This only reunites with the Mühlbach in Marchtrenk- Kappern .
The longest diversion is the inner water , it is diverted in Kappern and only reunites with the Mühlbach in the Oedt district of Traun.
Shortly before the confluence, the Weidinger Bach branches off at Traun- St. Dionysen as a secondary brook, which only flows back into the Kleinmünchen Canal south of the Linz train station in Kleinmünchen.
The catchment area also includes the Grünbach , which seeps north of Wels, and the Weidlinger Bach also includes the Hundshamer Bach (Perwender Bach).
history
Some documents indicate that as early as Roman times, at least the southern part of the moat of the city of Ovilava was fed by a forerunner of the Mühlbach. Bavarian graves from the Marchtrenk area also allow the assumption that there was a flowing body of water, as the settlers sought the proximity to usable bodies of water and a settlement of the otherwise very dry Welser Heide seems rather unlikely. The Wels castle was built in 776, there is evidence of a house mill, it could have been the first hydroelectric power station on the Mühlbach.
The first documentary mentions come from the late Middle Ages. At least from the second half of the Middle Ages on, some mills were built along the creek, some of which still exist today and are eponymous for some localities (e.g. Noitzmühle in Wels-Lichtenegg) in the Welser Heide.
use
Today, some farmers and companies operate small hydropower plants on the Mühlbach to generate electricity. In addition to hobby fishing right on the stream, some fish ponds are also fed with Mühlbach water. The trail name Fischergasse a little east of the city center indicates fishing in or near the stream.
The name Schwimmschulgasse on its length of 160 m to the right of the main arm above Pollheimerstrasse indicates historical swimming lessons in the stream. After crossing under Pollheimerstraße, just before the Ledererturm, there is an approximately 1 m high drop in the level of the brook, an indication that a slope was once used here for a mill. At the Zwinger next to the water tower, a small water wheel was only built in the last few decades.
At least until 1980 there were platforms made of wooden boards, about 3 m long and 1 m wide, with a board protruding about 12 cm high all around as a boundary, probably for safe water scooping, in some places, for example at the Zwinger, from the bank reinforcement just above the water level and washing and rinsing laundry by immersion in the current of water.
Until the 1980s, the water quality of the creek - triggered by wastewater from the pulp and paper industry discharged into the Traun - was very poor, the water quality improved considerably due to environmental regulations and modernization of industrial companies. In the meantime, there is even discussion about the establishment of bathing areas on the Mühlbach.
Individual evidence
- ↑ a b c d e Hydrographically, the Kleinmünchner Kanal belongs to the Mühlbach, its stationing up to the confluence with the Traun 37.2975 km; likewise Weidinger Bach and the other offshoots, and the side canal of the Kleinmünchner Canal in Linz- Traunau ; the short stretch of the Kleinmünchner Canal from the diversion to the Mühlbach confluence is called the Traun.
