The Wambach is a brook in Ansfelden and Linz .

The stream is around seven kilometers long. It flows into the Freindorfer Mühlbach , a tributary of the Krems , just above its confluence with the Traun .

The origin of the Wambach lies in the municipality of Ansfelden (Mair in der Than, Stark Golf) and flows in front of the bridge on the Kremstalweg over the city limits to Linz in the cadastral municipality of the same name Wambach . After this bridge at the level of the Waldbot farm, some of the water was already directed into the Stetingermühlbach, which fed a pond and powered a water wheel. Most of the water, however, was left in the original course of the stream.

After the bridge had to be rebuilt in 2006, the course of the road and the course of the brook were relocated. The reason was frequent flooding in this area. A straightening of the stream in Gottschalling up to Kremsmünstererstraße had already been carried out in the course of the construction of the Westautobahn in 1941. This measure had already caused major floods in 1943. After the completion of the motorway, the stream was led through an underpass into a concrete bed next to Wambachstrasse. A reservoir was built below the underpass at the end of the 1960s to remove alluvial material. Additional regulatory measures were carried out in 1972 on the right bank of the Mühlbach and the Kremsmünstererstraßenbrücke; on the occasion of the Unterwachtberg construction project, a 170-meter-long renatured section was created in 1997, in which the bank area was expanded from 15 meters to 50 meters. The construction of the Wambach Bridge in 2007 also made it possible to create a fish pass.

Fish stocks

According to a study from 1987, the fish population in the upper reaches of the Wambach is largely composed of minnows , while brown trout, aitel , gudgeon and loach are also represented in the lower reaches .
