River system Gullspångsälven
Gullspång is the power plant with the biggest output in the area. Lake Skagern is the storage reservoir for Gullspångsälven. Gullspång salmon are an exceptionally valuable strain of salmon, thanks to their fast growth and high final weight − approx. 6 kg on first reaching sexual maturity.
For spawning and growth, they are chiefly directed into two small areas of rapids downstream of Gullspång power plant and just upstream of the river mouth. The catchment area also includes the following smaller power plants: Skråmforsen, Björkborn and Bofors.
