The Arzler Bach is a left tributary of the Inn in Innsbruck , at the foot of the northern chain of the Karwendel .

Run

The stream is recorded from the cadastral border of the Innsbruck districts of Arzl and Mühlau (also known as Arzler Gießen ). It then runs from the south of the Arzler Kalvarienberg, largely completely canalised parallel to the Inn, eastwards, along the B171  ( Tiroler, Innsbrucker, or Haller Straße ), through Neurum and past Loretto near Thaur (name of the run here also Rumer Augiesen ). Finally it crosses (as Haller Giessen ) the old town of Hall and flows into the Inn at the Untere Lend - right next to the Weißenbach - at km 286.

The catchment area - it is only given to the north of the course, to the south is the direct catchment of the Inn - is about 26 km².

History and construction

The Arzler Bach was originally a small channel that flowed from the low mountain range near today's Olympic Village into the Haller Au , a wetland area of ​​the Inn below Innsbruck. The place Arzl, located in the limestone of the Nordkette and the glacial terraces of the low mountain range, has had a number of smaller, but not very productive sources since ancient times. Already in the High Middle Ages, the abundant water-bearing Mühlauer Bach from the Arzler Reise was tapped and diverted to the operation of Mühlen ( Arcelmülin 1288, today's Mühlau) and into the Rumer Mure .

From the 16th century the Mühlauer Bach also served to supply the city of Innsbruck itself. At the same time - Archduke Ferdinand II relocated the road from 1585-89 that had previously led through the villages of the low mountain range, today's B171, to the Inn - became the Haller Au drained and canalized ( Haupt Canal , Loretto Canal ), and fed to the city of Hall, which had to be found with the water of the Amtsbach , a branch of the Weißenbach via Absam. This main canal is today's Arzler Bach, which is also remembered by the names Rumer Augiesen and Haller Giessen for the lower reaches of the brooks that flow into the Au, which were also included.
