The Tobrabach , sometimes also called "the Tobra", is a brook with a catchment area of ​​47.8 square kilometers in the Naarn (river) network of waters in the Perg district in Upper Austria .

Surname

The Bach, which gives the town of Tobra in the cadastral community of Pergkirchen in the city of Perg , etymologically has Slavic roots ("Tobra" or "Dobra" for "good Bach"). The word "Tabra" already occurs with the Celts and indicates an area rich in water.

geography

The stream rises on the border with the municipality of Rechberg in the municipality of Windhaag near Perg , before it reaches the Machland is called Modlerbach and later Kropfmühlbach.

South of Tobra, part of the water is diverted into the artificially created Tobra Canal and fed to the Naarn in a south-westerly direction via the small Naarn Canal .

The Tobrabach itself changes direction about one kilometer south of Tobra and then flows eastwards along the border with Mitterkirchen , takes on the Arbingerbach and Deimingerbach and flows southeast of Kühhofen into the Mettensdorfer Mühlbach. The creek was mapped starting from the confluence with the Mettensdorfer Mühlbach over a length of 17.8 kilometers.

Tributaries of Tobrabachs are selected from wind Haag at Perg upcoming mountain stream, consisting of the location Saxenegg in the cadastral interior stone the market town Muenzbach coming sword Müller stream that from Priehetsberg coming to the market municipality Muenzbach Wiesbaden Lauterbach and at the boundary between Groißing flowing and Priehetsberg Falk Auerbach.

The Tobrabach touches or flows through the following communities: Rechberg , Windhaag near Perg , Münzbach , Perg , Arbing , Mitterkirchen im Machland and Baumgartenberg .

The catchment area of ​​the Tobrabach falls geologically into three of the 41 spatial units of the federal state of Upper Austria . The northern part of the Tobrabach valley including the headwaters is located in the Aist-Naarn-Kuppenland . The Tobrabach valley between the Stritzelmühle and the southern edge of the village of Tobra is one of the southern Mühlviertel regions . The area in the plain south of the Donau Straße and the Donauuferbahn lies in the Machland spatial unit .

history

Finds of flat and perforated axes made of serpentine suggest the presence of people in the Tobrabach Valley as early as the Neolithic (around 3500 years before Christ).

On the occasion of the separation of the property of the Lords of Perg and Machland around the year 1100 AD, the Tobrabach formed the border, with the area east of the brook going to the Machländer and the area west of the brook to the Pergern.

The Tobrabach formed the eastern boundary of the parish in 1142 when the parish of Pergkirchen was founded, in 1784 the eastern boundary of the cadastral parish and in 1848 the local parish of Pergkirchen. Since the amalgamation of the municipality of Pergkirchen with the Markt Perg in 1938, the Tobrabach has largely formed the eastern border of the market municipality of Perg, which was elevated to a town in 1969.

economy

Several mills were in operation along the Tobrabach in earlier years (Schwertmüller, Kropfmühle, Stritzlmühle, Stegschmied, Frühmühle, Erlmühle).

Flood protection

Starting in 2014, the Tobrabach will receive the largest retention basin in the Mühlviertel with a height of 11 meters, which will protect the village of Tobra from future flooding. The nine-hectare reservoir extends from the Frühmühle to the junction of the Urtaler goods route and has a capacity of 233,000 cubic meters. The Tobrabach takes water from a 22 square kilometer catchment area, which includes the municipalities of Windhaag, Münzbach, Perg and Arbing, is dammed over a length of 200 meters in the event of a flood and the flow rate is reduced. 40 houses in the village of Tobra north of federal highway 3 are protected.
