Location of Lounatkoski in Finland

Municipality of Suomussalmi (www.suomussalmi.fi)
Hossa National Park 
The spot is managed by Metsähallitus.

The Lounatkoski Rapids are particularly beautiful at the time of the spring flood. The power of the rapids was formerly utilised in the milling of grain. For log floaters Lounatkoski was a tough place.

Wood and Grain

At Lounatkoski, there are structures related to log floating and the milling of grain. In the old days, the rapids provided water power but also set challenges to log floaters. The original watermill was pulled down but a similar mill was brought here from the nearby Lavajärvi.

The remaining log-floating structures at Lounatkoski are a log-floating dam and a storage space for the beams that were used to regulate the flow through the opening in the dam. Beneath the bridge crossing the rapids are the components that controlled the course of the logs. The cabin used by log floaters has been renovated and is today used as a rental cabin.
