The rapids of the waterway of Saarijärvi have been used for log floating from 1860´s to 1960´s. Due to this, nearly all the beds in the rapids have been modified to suit the needs of log floating. After the log floating stopped, there have been attempts to restore the rapids closer to their natural state. This process of restoration will take place before the end of this century on the rapids Heijostenkosket. The whole restoration process aims at creating better possibilities for fish to breed and for fishermen to fish.
