The Kronawittbach is a small brook near Schildorn and Pramet in the Innviertel of Upper Austria .

Run and landscape

The Kronawittbach rises near Wolfersberg on the northern flank of the Hengstberg  ( 683  m above sea level ), a ridge in the main ridge of the Hausruck – Kobernaußerwald train , on the Schildorn municipality. It flows northeastwards past the village of Sankt Kollmann to Kronawitten (the location extends on both sides of the brook in both municipal areas). From this place it got its name, to Kranewitt ' Wacholder '. The Gumplinger Bach flows here on the right . Then the Kronawittbach turns northwards, the Schilddorn – Pramet municipal boundary changes sides several times. The stream flows here through Rödt (municipality of Pramet) and between Au (Schildorn) and Knitzing (Pramet). At the bridge on the L1069  Schildorner Straße near Aigen (Schildorn) and Ecklham (Pramet), where the stream forms the municipal boundary, after about 5 km it flows into the upper Oberach , which comes from Pramet and flows to Ried to the Antiesen .

Its valley is an agricultural area in the transition zone from the Innviertel hill country to Hausruck and Kobernaußerwald. The north- wandering Riedel rise in the upper course around 100, in the lower course 20-50 meters above the valley floor. Its source course still forms the border to the closed forest area of ​​the Hausruck – Kobernaußerwald-Zug, then it mostly flows through small-structured arable land lined with wood . In the estuary there are fringing forest remains of an oxbow lake.

Hydrology and construction

The stream is largely natural, only in the upper course near the spring has been straightened a piece to form a drainage ditch . The gravelly gravel bed has good trout spawning areas, but is inaccessible to migrating fish due to several transverse structures. All of them are no longer used mill weirs that could be dismantled as part of the EU Water Framework Directive .

The water quality is generally good, with a slightly higher bacterial count due to the agricultural environment.
