    Key features of the case study

    The restoration project is situated in the river Storå At this point the upper catchment measures about 878 km². The mean discharge near the site is 16.1 m³/s. In this section the Skjern is 5th order stream. River Storå is the 3rd largest river in Denmark and drains the western part of the peninsula Jutland.

    Site description

    Measures selection

    Some parts of the river were channelized during 1950’s, however large reaches of the river have also been left untouched. Smaller in-stream habitat improvements have been conducted over the years, including addition of coarse material for improving salmonid spawning. The main aim of the project was to improve conditions for salmon in the Storeå by creating new spawning areas and additionally for lampreys being embraced by the EU Habitats Directive. Furthermore the project aimed at improving conditions for grayling that is currently declining in Denmark. In autumn in 2011 a total amount of 700 m3 coarse substrates in the form of gravel, boulders and a few larger stones were added to a 50-60 m long reach in the Storå thereby increasing the area available for spawning for salmonoid fish. The addition of substrates is expected to increase the water level app. 20 cm just upstream of the gravel bar.
