The Goldach has its source in Appenzell near the Ruppen Pass at an altitude of 1016 metres. It flows through precipitous gorges and ravines to the village of Goldach, where it flows into Lake Constance. The embankments of the Goldach are in a perpetual state of flux, while the appearance of the impassable canyon landscape is constantly shifting and evolving. The Goldach is highly valued by the local population and, where accessible, this body of water is used for recreation.
With its pristine wilderness and areas beyond the reach of humans, the Goldach offers unique habitats for native flora and fauna. Fish species such as bullhead, grayling and river trout, as well as stone crayfish and European crayfish, have been found in the waters of the Goldach. A wealth of endangered insect larvae make a home in its bed, while numerous amphibian and reptile species live on its waters, including the rare midwife toad and the yellow-bellied toad. The Goldach is a site of high biological value. Due to the continual movement of the banks, large volumes of dead wood and the highly dynamic water ecosystem, new habitats are constantly being created, harbouring a high level of biodiversity. The Goldach also plays a vital role in the breeding season of the Lake Constance trout population, being the second most important tributary to the lake after the Steinach.
Within the perimeter spanning from the Bädli in Trogen to the Achmühle, including tributaries, the Goldach is certified with the Gewässerperle PLUS label (15 June 2024 to 14 June 2029).
