The fish can travel to their spawning grounds through the bypass. The bed completed during the fall is the largest in Finland so far.
In Varkaus, Finland’s largest bypass channel for migratory fish was opened.
About 100 people were there to listen to the speeches and watch the opening. The excavator moved the rocks aside from a distance of about 20 meters.
Uoma is located in Ämmenkoski in the middle of Varkau, between Haukivesi and Unnuka. A 170-meter-long and ten-meter-wide channel was built past the regulation dam in the rapids, along which migrating fish reach their breeding grounds.
Hundreds of square kilometers of waterways that had been closed for more than 100 years were restored to Saimaa’s lake salmon and lake trout.
It is also significant that there is enough water in the rapids for migrating fish all year round thanks to the sufficient environmental flow.
Work in the area will continue next summer. At that time, the smaller rapids in the Kämär area will be renovated.
