The Aitrach is the left tributary of the Iller with the most water in the Baden-Württemberg district of Ravensburg towards the end of its middle course. After a roughly northern run of about 15 km in length, it flows into the municipality of Aitrach . Together with its longer upper course, it has a total length of around 50 km.

geography

course

The Aitrach arises from the confluence of the longer Eschach , which tapers from the right and south-southeast, with the more water-rich Wurzacher Ach , which comes from the left and west, at 625.1  m above sea level. NHN near the hamlet of Lauben in the Wuchzenhofen district of Leutkirch in the Allgäu . From there it flows in an initially northeastern, later northerly direction in the Westallgäu through the Nibelgau . She soon moves to the municipality of Aichstetten and passes the village of Altmannshofen on the left bank and then the main town on the right bank. Further down, it separates the eponymous village of the municipality of Aitrach on the right from the municipality of Marstetten on the left and flows further down, halfway to the next village of Mooshausen, from the left and at about 584  m above sea level. NHN in the Iller .

The Aitrach is only 14.9 km long from its own origin and remains in the Ravensburg district for its entire length. Its longer upper course, Eschach, rises in the neighboring Bavarian district of Oberallgäu to the east . It flows about 41 meters below its confluence and has a gradient of about 2.8 ‰ on this route.
