After a few minutes searching on the web, i believe this is a picture of the Haapavitja rapid in the Ruunaa district.
In the Ruunaa district there is almost 20 km of water course, which include ca. 8 km of rapids and fast flowing currents.
Ruunaa rapids are part of the Lieksa river, which flows out from the vast woods of Russia.
The first two hundred meters of Haapavitja are the nicest. From the edge onwards the waters start surging down rather steeply for some hundred meters. You'll find the best spots in Haapavitja rapid by the stout blocks, which may hide a lot of trout. It is not unusual to hook over 40 cm ones there with a large-sized fish imitation fly. - in: http://www.fishinginfinland.com/PublisherFishinglordsSingleCard?selectedObject=102
