Klarälven (=clear river in Swedish) is the longest river (460 km) of Sweden. From way back, this river has brought significant economic benefits. Nowadays, this river is well-known throughout the entire world for its perfect fishing water. This river is extremely suitable for fly-fishing. You can’t hardly imagine it, but in the middle of Karlstad (capital city of Värmland) huge perches are caught. This river also contains pike perch, rock-bass, bream and salmon.
