Hydropower poses a major threat to both upstream and downstream migrating Atlantic salmon (Salmo salar L.). To ensure a relatively safe route for migrating fish, fish ways and different guidance structures are constructed to help fish to bypass the turbine intakes to power stations. The success of these constructions varies and is generally dependent on the local river conditions. In 2010, a fish guiding structure was installed in Sikfors power station, River Piteälven, to improve the downstream migration for smolts of Atlantic salmon. In the year of installation, a study aimed to evaluate the success of the guidance structure failed due to technical problems. The aim of this thesis was to evaluate the fish guidance structures abili...
