Fallbach and Feientobel in Dornbirn seen from "In Steinen" (Bremenmahd) with little water. On the right a part of the Breitenberg and in the middle behind it, the Staufen

The Fallbach is a flowing body of water that flows from the Staufenalpe (municipality of Hohenems , source at around 1116  m above sea level ) via the Feientobel to the Landgraben (mouth around 416  m above sea level ). The Fallbach begins at water kilometers (GwKm) 5.47 and flows roughly from south to north and changes at GwKm 2.18 in a westerly direction.

In a north-westerly direction, the Fallbach shows an imposing waterfall that can be seen from afar, but its amount of water is heavily dependent on the previous rainfall and thins out during longer dry periods.

Tributaries

At river kilometer 5.47, in the municipality of Hohenems , near the Staufenalpe, the Fallbach rises from a source and keeps its name from here on. Seen from the source, the stream flows to the left of the Staufen to the Kühberg in the Dornbirn municipality, through the Feientobel past Haslach to the Landgraben and quickly takes on several tributaries.

Significant tributaries of the Fallbach are (seen from the origin) in the upper area up to the mouth at river kilometers:

  • 5.13 a second unnamed source tributary (Hohenems, Staufenalpe), R,
  • 4.46 and 4.40 and 4.29 unnamed source tributaries (Hohenems, Ruheshütte), L,
  • 3.72 and 3.43 each an unnamed source tributary (Hohenems, Staufen ), R,
  • 2.56 an unnamed tributary near Haslach , L,
  • 1.85 the Küferbach (Dornbirn - Wallenmahd ), R,
  • 1.36 derivation Fallbach old (Dornbirn - Wallenmahd - operating area), R,
  • 1.07 the Steinengraben (Dornbirn - Wallenmahd - operating area), L,
  • 0.95 den Satzbach (Dornbirn - Wallenmahd - operating area), L,
  • 0.32 old Fallbach supply line (Dornbirn - Wallenmahd - operating area), L,

(R = inflow from the right / L = inflow from the left).

At river kilometer 0.00 the Fallbach flows into the Landgraben near the district Wallenmahd (river kilometer 2.656 of the Landgraben). The Landgraben forms the municipal boundary between Dornbirn and Hohenems between GwKm 0.82 and GwKm 3.10 and flows into the Rhine Valley inland canal at GwKm 6.75 , then into the Dornbirner Ache and into Lake Constance .

In the lower area, the Fallbach was expanded from 2008 to 2011 in order to increase flood security.

Offending communities

In the upper area, the Fallbach flows for about a third of its length through the political municipality of Hohenems.

At around river kilometer 3.72 the stream flows into the municipality of Dornbirn.

Economic use

The Fallbach was used economically in the past and the healing spring for Bad Haslach is believed to have originated from an infiltration of the Fallbach.

Fallbach old

The original Fallbach flowed around 600 m across the "Fussenegger Business Park" (formerly JMFussenegger Textilwerke) and was re-routed along the eastern and southern property boundaries.

Feientobel

The Feientobel, through which the Fallbach flows and washed out, separates the Karren from the Breitenberg . The Feientobel is natural and very impressive with the washed-out rock faces and waterfalls. Ropes and holding bars are installed in the ravine. For safety reasons, the preferred walking direction is from the bottom ( Haslach , 443  m above sea level ) to the top ( Kühberg , 950  m above sea level ). The Feientobel is only shown on good hiking maps, it is not an official hiking trail (orientation on the signs Karren, Kühberg, Leiterweg , Schuttannen) and should not be used in rainy weather and snow conditions. Very good shoes, surefootedness and a head for heights are required.
