The Balbierbach is a right tributary of the Ill in Vorarlberg , Austria .
description
The sources of the Balbierbach as a wild brook are on the one hand on the Augstenboden between Grappes and Maderer at around 2,500 meters above sea level, on the other hand the brook is fed from the small lakes on the Luterseeberg next door and not least through brooks and ravines from the Roßberg further west. On Luterseeberg, the first archaeological excavations took place in the former mining area in summer 2008 and 2009. Overall, the catchment area including the valley basin with the Alpe Nova, all together approx. 2 × 4 kilometers wide and deep, with a total of approx. 9 km² is drained. Passing the Maisäss Oberer, Mitteler and Unterer Netza on the right and Manigg on the left, the Balbierbach comes to the waterfall above Gortipohl in Winkel. However, all of these waters have to flow into the valley via the waterfall above Gortipohl.
History and construction
The Balbierbach is especially important because in all the centuries before it was built, with every major storm it devastated the center of Gortipohl with mudslides . Some of these are noted in the old church chronicles and still describe the force and danger that can be expected today.
After the storm in 1956, the responsible authorities decided to block the stream with torrent and avalanche barriers (WLV). For this purpose, a funnel-shaped wall 6 meters high and about 200 meters long on both sides was first erected below the waterfall , so that all water in the existing creek bed should be led into the Ill even in storms.
For the remaining 600 meters, the course of the brook has been through meadows and forests, as always. The old natural stone masonry currencies are partly still there. After the major storm in spring 1999, this unsecured part of the stream was cleared down to the bottom at the insistence of the neighbors, in order to prevent further mudslides on the left and right. The subsequent storms in the same year meant that the Balbierbach had to be cleared a second time with heavy equipment. In the hot summers of the following years, the water in the lower reaches of the Balbierbach partially seeped away through the torn up river bed or simply evaporated between the hot stones in the stream bed. The trout stock suffered as a result.
After the last storm in the Alps in 2005, which once again severely damaged the pedestrian bridge in front of the waterfall and also caused mudslides in the meadows below the B188 bridge, the brook had to be cleared due to a lack of safe construction. Due to the "quick" clearing of the river bed only, bank erosion occurs in the area of the protective forest along the river after every storm wind.
As a result of the municipal council meeting on August 11, 2005, reports were made that the missing section would soon be built on. The latest building project was presented by the WLV in the Gortipohl school hall in March 2006, so there is hope that the building will take place in the next three to four years. In 2019, the work from the Gortipohl waterfall down is almost half finished.
