Between Lake Norra Bredsjön and Lake Stora Korslången, there is a 50-meter stretch without a water connection. Today, there is a land transport path for canoes and kayaks along the paddling route. In the past, this was a transshipment point for iron ore. The iron ore came from the mines in Grängesberg and was transported via the lakes to the smelters at Kloten and Bredsjö. Remnants of a railway track, on which wagons were pulled between the two lakes, still exist.
