The Leiblach , formerly Leubelach , is a more than 30 km long tributary of the eastern Lake Constance and thus the Rhine . It runs roughly the first three quarters of its way in the Lindau district in the German state of Bavaria , after which it is its border river to the Bregenz district in the Austrian state of Vorarlberg .



The Leiblach arises at about 687  m above sea level. NHN in the scattered settlement village Riedhirsch of the Heimenkirch market in the Bavarian district of Lindau and runs through Heimenkirch on the first third of its way a little west to west-northwest to almost the hamlet of Lingenreute in the municipality of Opfenbach . There it begins a wide arc to the northeast, in the course of which it passes the parish village of Wohmbrechts von Hergatz and then finds itself at the village of Hergatz in its steady direction to the south-south-west. The following middle course is deepened like a gorge . It then flows roughly on the municipal boundary between Hergensweiler on the right and Sigmarszell on the left. From the inflow of its largest tributary, Rickenbach, from the east at Sigmarszell-Burgstall, which is ultimately the border water between Bavaria and Vorarlberg , it is then itself on its lower reaches the state border between Germany and Austria . Sigmarszell now borders the right bank for a long time, while the Vorarlberg communities of Hohenweiler and Hörbranz lie one after the other on the left . At the level of the town of Hörbranz on the left bank, the area of ​​the district town of Lindau (Lake Constance) begins on the opposite . In the now less deepened valley, the river crosses the Leiblach Bridge of the E 43 . Between now more densely populated areas left and right it reaches between Hörbranz-Unterhochsteg left and Lindau- Zech at 395.23  m above sea level. NHN the Bodensee .

The Leiblach is 31.9 km long and flows about 292 meters below its source, it has an average bed gradient of about 9.1 ‰.

Catchment area

The catchment area is around 103 km², around three quarters of which are in Bavaria and a quarter in Vorarlberg. From a natural point of view it belongs to the Bodensee-Jungmoränenlland , a part of the pre-alpine hill and moorland in the Alpine foothills .

In the major part of the catchment area there is a young moraine from the Würm period, and peat areas are also found. The middle and lower Leiblach as well as some of its tributaries have dug into the Upper Freshwater Molasse. The river bed initially consists mainly of river gravel and sand , later of solid molasse rock .

Water flow

With an average water flow of 3.4 m³ / s, the Leiblach is the seventh largest feeder to Lake Constance, to which it feeds 0.9% of its inflow.

Fauna & flora

As a river biotope, the Leiblach forms a habitat for some endangered fish species such as streamers , tailors , noses , cops , brown trout and grayling . For this reason, the part of the river in Germany was registered as a Natura 2000 area. In Vorarlberg, too, 7.62 hectares are designated as FFH areas.
