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. 

More about Lounatkoski 

Along with the timber trade, floating had begun on Hossa waters by the late 1800s. Some water routes were cleared and some facilities were built for the purposes of log floating during that time. In Hossa, for example, there are still old log-floating dams and bridges, apparatus for steering the course of the logs and log floaters' cabins. Along the shores of the water routes there are also tree stumps with holes in them, which are further reminders of the old log floating days. These stumps were needed for the twisting of the fir branches that were used for tying up floating barriers. Additionally, the water routes were also very important for movement and transport. In 1902, there were only 26 km of road in the whole municipality of Suomussalmi.

In Lounatkoski, the apparatus that steered the course of the logs in the rapids, two log-floating dams, and a storage space for beams and a boathouse can still be seen. The log floaters' cabin built in the 1930s today serves as the Lounatkoski rental cabin. It has been protected by the National Board of Antiquities. 

Agriculture was an important means of existence in Kainuu. During the era of self-sufficiency farming, rye and barley were grown in small fields. The grains were ground by hand or taken to be ground by a watermill. In Hossa there were formerly three mills; one in Lavajärvi and two in Lounatkoski. One of the Lounatkoski mills was pulled down and the Lavajärvi mill was brought to the same site. The mill is in working order. Nearby there is a private mill site, where there are the remains of a mill and a mill cottage. Additionally, at Lounatkoski, there are also the remains of a mill sauna and the foundations of a forest road that was used in the transport of logs by horse.
