The Branntweinbach is a historic stream in the north of Augsburg that originally originated in what is now the Hammerschmiede area and ran north through fields before finally flowing into the Lech opposite Stettenhofen. The regulation of the Lech in the 19th century caused the groundwater level to sink, which led to the Branntweinbach drying up.
In 1996, a project was initiated to re-irrigate the Branntweinbach. Since there was no natural water available on the east side of the Lech, a pipeline (culvert) was laid under the Lech to take water from the Lech side canal to the west. The water pressure now allows one cubic meter of water per second to reach the east bank. There it emerges in an artificial spring and initially feeds the newly created Chardonnaybach, which flows into the Branntweinbach after 850 meters.
The re-irrigation of the Branntweinbach has led to the development of valuable wetland habitats. The presence of the beaver in particular has contributed to the return of amphibians, dragonflies, reptiles and typical marsh plants. However, the activities of the beaver also mean that pedestrian paths are permanently flooded and the water no longer follows the planned course. Nature conservation is currently trying to specifically direct the activities of the beaver so that the water flows through again.
The Branntweinbach and its surroundings are popular destinations for hikers and nature lovers. A nature trail, known as the “Jungle Trail in the Lechauen North”, leads through parts of the biotope and offers informative panels on the flora and fauna of the region. Guided tours are offered by the Augsburg Environmental Station.
The re-irrigation of the Branntweinbach is a successful example of renaturation measures that bring both ecological benefits and create recreational opportunities for the population.
