The Tagerbach is a 10 kilometer long stream south of Linz in Upper Austria. It rises in the municipality of Sankt Florian and subsequently forms the border between Linz and Asten .
Run and hydraulic engineering
The Tagerbach rises at the northern tip of the Traun-Enns-Platte southwest of the Florian district Rohrbach behind the Marienhof (Rohrbach 13). Halfway along the course of the stream, the stream at Hof Zehenter ( Gemmering ) used to drive a ram to supply water and a water wheel.
The stream flows to Bruck bei Tödling , where it enters the Linzer Feld . It passes under the West Autobahn as well as the nearby B1 . There it reaches the Linz cadastral community of Pichling in the Ebelsberg district and forms the border between Linz and Asten . Originally the stream seeped away in a swampy area, but it was regulated early on and used for irrigation in agriculture. In the 1960s, the Linz magistrate's water book noted 28 irrigation rights between the city limits and the estuary. Today's Tagerbach continues along the city limits, past Pichlinger See and is carried out under the Westbahn route. The Mönchgrabenbach flows into this area as a channel, and a catch basin was created to hold back excessive flooding. The Tagerbach and the Aubach meet at Raffelstetten .
The confluence of the Tagerbach in a reed belt of the Altau in the Probstau- / Raffelststättenstraße area was artificially created and has to be permanently maintained, otherwise the Tagerbach would constantly change its course. This wetland drains towards the old course of the Ipfbach .
ecology
Despite the technical construction, its lower course is ecologically valuable. In the boggy ditch at the Aubach confluence, there are several amphibian species, including the rare spadefoot toad , many species of birds and a number of dragonflies, including the southern damsel . This section is part of the European protection area Traun-Donau-Auen ( Fauna-Flora-Habitat- Area). The estuary forms a swampy moat with the character of an eye water, with open water surfaces, reeds and willow thickets, but is not specially protected.
Fish are only found in the lower reaches of the river, predominantly rut and hazel .
