geography

course

The stream rises at 511  m above sea level. M. on the Beerenberg south of the Beerenberg monastery ruins . Early after the source, the brook flows through a small pond near the Upper Berenbergstrasse.

From the pond, the brook flows for around 500 meters to the eastern edge of the forest at the beginning of Niederfeldstrasse, where the brook takes up the Tannholzbach on the left and is overturned and invisible for almost the rest of its course. Only for a 100-meter-long stretch is the brook on the surface until it flows into the Töss. The stream also crosses under the Hardau settlement.

As part of the renovation for a flood of the century , however, a renaturization and exposure of the stream is planned for the last 375 meters up to the 100 meter long exposed section. The brook would flow around the Hardau settlement and flow into the water channel of the small hydropower station Hard. A corresponding plan was published by the city of Winterthur in November / December 2018. The total project costs are between CHF 600,000 and CHF 800,000, of which CHF 300,000 will be borne by the City of Winterthur.
