The Müllerbach is about 4.95 km long flowing water that flows from the Dornbirner Ach at river kilometer 16.83 as a works canal at about 468 m above sea level. A. is branched off ( Tyrolean weir ) and can lead to up to 2200 liters / second. It flows exclusively through the area of the city of Dornbirn ( Vorarlberg ). The Müllerbach begins parallel to the Dornbirner Ach at the level of the Enz plot (a little below the Waldbad Enz ) in the south-east of the city and flows in a large arc to the north-west . In the lower area of the Forach district it still has an average of around 1600 liters / second of water flow ( Forach power plant ).
The water is dammed along its entire course . Direct access is in some cases no longer possible due to superstructures and pipework.
history
In 1585 the following mills were in use in Dornbirn according to a princely account book: the mill, called die Segen (the sawmill after which the settlement Sägen is named), the mills in the Kehlen and in Adelsgehr, the Schnellenmüli am Stiglbach (Haselstauderbach), the lower mill on the Stiglbach, the mills in Völckistobel, in the Ried (the old Riedmühle), on the Dornbirnerach, the lower and the upper mill on the Steinebach , the mill in Schnellen, a saw in the Achmühle , a grinding mill and water hammer without a location and one Grinding mill on Gießen, a predecessor of the Müllerbach.
The Müllerbach was created as an artificial flowing water (works canal) in the 17th century and ran above the Sägen plot to the Schmelzhütten plot (e.g. at the Helvetia inn) and there it flowed back into the Dornbirner Ach. As early as the 14th century, a "Müllerbach" is said to have emerged as a short diversion from the Dornbirner Ach to use a first Achmühle.
In the course of time, more and more companies and power plants were added, so that the canal was lengthened up and down.
The entrepreneur and Dornbirn textile pioneer Karl Ulmer (1773–1846) had the canal extended from the Schmitten parcel around another two kilometers to the Karlsgraben in order to use the water power for his factory (e.g. weaving machines ). In 1831 the version of the Müllerbach in the Enz was changed for the last time in the course of the introduction of the Dornbirner Ache. The canal still exists in this length and shape today.
Inflows - outflows
The Müllerbach has two relevant tributaries and an outflow from or to other upper waters. At river kilometers 4.39 there is the possibility and the right to use the crossing Gechelbach water up to max. 200 l / sec for the Müllerbach. Shortly before the confluence of the Müllerbach and the Karlsgraben, the Dorfer Feuergraben flows into the Müllerbach at around river kilometer 0.10. In the area of the Werkhof of the city of Dornbirn in the Vorderen Achmühle there is an underground emergency outlet into the Dornbirn Ach, in which the flow of the Müllerbach is throttled to a maximum of 1850 l / sec.
At river kilometer 0.00 the water flows into the district Rohrbach (parcel Forach) into the Karlsgraben (river kilometer 1.37 of the Karlsgraben) and from there subsequently together with the Fischbach at river kilometer 1.23 into the Fußenau Canal . The water is only released back into the Dornbirner Ache at river kilometers 7.84 (together with the treated wastewater from the Dornbirn-Schwarzach wastewater treatment plant via the Karlsgraben ).
function
Since the decline of the textile industry in Dornbirn at the end of the 1980s, the Müllerbach has had little economic importance for the companies located there. For the maintenance of the groundwater level, the design of the site and cultural and historical memory, it is still of considerable importance for the population.
Hydrological function
The Müllerbach takes over the function of a receiving water and self-cleaning for the Dornbirner Ache and the Gechelbach as well as in the area of the urban area of Dornbirn the superficial drains.
The Müllerbach in the area of the city of Dornbirn has an indispensable function for stabilizing the groundwater level.
Tourist use
Use as bathing water (tourism) is excluded due to the high flow velocity.
Economic use
The stream was created for the technical use of water power for the textile industry, forges, sawmills and mills (e.g. gypsum mills, sulfur mills) and was of decisive importance for the economic development of the city at a time when electrical energy was not yet continuously available stood, among other things z. B. for the textile companies of Johann Baptist Salzmann, Karl Ulmer, the companies Herburger and Rhomberg, FM Hämmerle , Rhomberg Textil or the metal processing company Rüsch-Werke (today: Inatura ).
Several electric power plants are still in operation along the water.
Power plants on the Müllerbach
Originally there were twelve power plants on the approximately 5 km long Müllerbach (one power plant on average every 400 m). Only three of them are still in operation, two of which (Forach and Stadtgarten) have been renewed.
Active power plants

Ownership
The Müllerbach was originally owned by several people and companies that formed the Müllerbach competition. In 1923 the Müllerbachgenossenschaft was founded by being entered in the water book of the Feldkirch district administration and on March 16, 1925, it received its own statutes and became a public corporation. The owners were given unlimited water usage rights because the rights existed before the Water Rights Act 1870. Of the original nine members of the cooperative
- Herrbruger & Rhomberg, Textile;
- Fa. FM Hammerle , textile;
- Anton Winsauer, sawmill;
- Johann Winsauer's heirs, sawmill;
- Rüsch Werke (Rüsch-Ganahl AG), machine factory;
- Franz M. Rhomberg, Textile;
- Jenny & Schindler, textile;
- Josef Lugers Erben, Mühle;
- JG Ulmer (later Franz M. Rhomberg), textile;
there are still three today:
- City of Dornbirn;
- Rhomberg Liegenschafts-Gesellschaft mbH & Co .;
- Zumtobel Group
and five landowners are obliged to maintain the channel:
- JA Fussenegger, timber construction;
- Messrs. Rudolf Ölz master baker ;
- FM Zumtobel, investment company;
