The Aiterbach is an almost 30 km long right tributary of the Traun in Upper Austria .

course

The Aiterbach rises northeast of Etzelsdorf in the municipality of Pettenbach at the foot of the Magdalena mountain at an altitude of around 565  m above sea level. A. It flows north in a gently cut valley through the Traun-Enns-Riedelland and passes the communities of Ried im Traunkreis , Eberstalzell , Sattledt , Steinhaus and Thalheim near Wels and flows into the Traun near Wels . In its course it takes in only a few smaller tributaries.

Water flow

The mean discharge at the Oberschauersberg gauge is 0.71 m³ / s, which corresponds to a relatively low discharge rate of 10.4 l / s · km². The Aiterbach shows a balanced pluvio-nival discharge regime with the maximum in March and the minimum in September. The monthly mean of the month of March with the most discharge, at 0.88 m³ / s, is only around 30% higher than that of the month of September with the lowest discharge, with 0.64 m³ / s.

nature

The Aiterbach valley near Steinhaus

The Aiterbach, which mostly flows away from larger settlements, is largely natural in its entire course, with meandering courses in places, wood along the banks or alluvial forests ( ash or ash, black alder and wet forests).

The wet meadows that accompany it in parts represent a habitat for wet meadow dwellers such as marsh grasshoppers or long-winged sword insects.

The Aiterbach counts for trout and grayling region, mainly fish species are brown trout and rainbow trout in the lower reaches of the grayling .
