The Weißenbach is a left tributary of the Inn in Tyrol , which drains the Halltal .

course

The tributary Eibentalbach

The stream rises as Issbach am Issanger at an altitude of 1584  m above sea level. A. and flows through the Isstal towards the east. Below St. Magdalena it unites with the mountain stream , also known as the Salzbergbach or Eibentalbach , which comes from the former salt mine. As Halltalbach it flows through the Halltal first in an easterly, then in a southerly direction.

At the Hackl estate at the exit of the valley, the stream is divided, the main part flows in a wide, gravel-filled stream bed as Weißenbach through the Milser Heide and forms the western municipal boundary from Mils to Absam and Hall in Tyrol . Here the Weißenbach has already been straightened several times, as it had already flooded the place several times. The other part flows as the Amtsbach to Absam, where the Baubach again branches off to the east. Amtsbach and Baubach were artificially created in order to drive mills, forges and other works in Absam and Hall. The Amtsbach flows in the center of Hall into the Arzler Bach , which has crossed the old town of Hall since the Haller Au was drained in the late 16th century and goes to the Inn directly above the Weißenbach estuary at the Untere Lend .

Catchment area and water supply

The Weißenbach drains a catchment area of ​​20.4 km², the highest point of which is the Großer Bettelwurf at 2726  m above sea level. A. is. Below the 2nd Ladhütte in Halltal (around 6 km above the mouth) the mean discharge (MQ) is around 1.1 m³ / s. The runoff regime is strongly seasonal, the highest runoff occurs in summer, the lowest in February and March. While the outflow of the mountain stream in winter is around one sixth of the amount in summer, the Issbach can often dry out completely in the winter months from January to April.

use

In 1913 the Halltalkraftwerk of the city of Hall at the Walderbrücke was put into operation, which has a bottleneck output of around 1800 kW .

Spring catchments from tributaries of the Halltalbach supply more than 20,000 people in Hall and Absam with drinking water. Since the beginning of the 2000s, the drinking water power plants "Stollen power plant Bettelwurfquellen" and "Jakobibründl" and since 2006 the drinking water power plant "Walderstraße" have been supplying electricity with a bottleneck output of around 85 and 325 kW.
