The Allmannsweiler Bach is a four kilometer long river in the city district of Friedrichshafen in Upper Swabia Lake Constance district in Baden-Wuerttemberg , in the district of Löwental from left to the Bodensee flowing rotách flows.

course

The Allmannsweiler Bach arises at the edge of a field on a flat southern slope north of the Dornach forest area , roughly in the middle between the Friedrichshafen villages of Hirschlatt in the northeast and Hagendorn in the southwest, and after 250 meters it enters the forest, which it flows through to the south. Towards the end of it he only runs from the right after 1.1 km to 409.4  m above sea level. NN a tributary from the western edge of the forest, then already outside from the left a longer one in a twisted section under the Friedrichshafen exhibition center , in which it also feeds a 0.4  hectare pond.

After crossing under Allmannsweiler Straße, the brook runs open again in a fairly shallow hollow between fruit crops, other cultivated land and scattered settlement houses of the western edge of Allmannsweiler, initially southwest, then south, and thus reaches the western edge of the airfield, which it is outside the fence and next to the K 2772 follows southwards. After crossing under the B 31 by means of several culverts at its access junction at Löwental, it runs a little parallel to the Rotach, which flows here to the southwest, and then flows into the river from the left immediately below the river weir in the Löwental district , which is one and a half kilometers further down into the Bodensee pours.

Catchment area

The Allmannsweiler Bach drains an area of ​​about 5.7 km², the longest stretching from the northeastern edge of Ailingen about 3.6 kilometers south to the mouth; across it, the catchment area has a maximum width of 2.3 kilometers. Its highest point is close to its northern tip at the Haldenberg chapel of Ailingen in the southernmost landscape conservation area Haldenberg , where the eponymous range of hills, which continues northwards, is 479.3  m above sea level. Reached NN ; More typical of its northern border is the west-east, about 440  m above sea level. NN high hill threshold near Hirschlatt, on the southern slope of which the start of the course lies.

The drained area is surrounded by the catchment area of ​​the Rotach itself in the southeast and in the entire west, from northwest to east the Schussen competes beyond the watershed , mostly via its right-hand tributary Tegelbach near the mouth .

Around two thirds of the catchment area is covered by Würm moraine sediment, around one third on the southeastern edge by Würm gravel, which the stream entered at the edge of the airfield. On the northeastern edge near Hirschlatt, a small snippet of a freshwater molasse island extends into the catchment area.

In the Dornach the stream and its tributaries have very natural courses. At the edge of the airfield, it passes through a wetland.
