	The restoration plan aimed to slow down the current and produce suitable nesting habitats for the trouts and shelter places for the juveniles. Also versatility to the river bed was improved by digging few wider areas. Gravel was brought approximately 40 m3 and placed to the river in several places bed to ensure the nesting habitats for the migratory fish. Before the restoration many stones were taken away from from the river and places a side of the river. All the stones that were piled up next to the river were used in the restoration work.

	Also in the section three, the ~~culvert~~ was altered so that the erosion that ~~was~~ in the channel would be protected from further erosion. Also in the section four the river was made more curvy to reduce the erosion in the channel and to protect the sand from accumulating to the river bed.		Also in the section three, the channel curve was altered in few places so that the erosion that occured in the channel would be protected from further erosion. Also in the section four the river was made more curvy to reduce the erosion in the channel and to protect the sand from accumulating to the river bed.

	The lenght of the first restored area is 430 meters and the width is 4,3 in average. The Second was 540 meters long, width 6 meters and the area in total was 3 240 m2. ~~The restored rapid area in the totally was 1900 m2.~~ The thirds section was 300 meters, width 6 meters and the area was 1 800 m2. The last section was 570 meters long, width 8 meters and the total area reached up to 4 560 m2. The elevations difference in the restored area was 18 meters.

The restoration was made to improve the living conditions of the fish and other species. Rocks and gravel was placed to the river to make rapid areas more suitable for the trouts to reproduce. The aim of the retoration was to improve the living conditions of migratory fish and to make the river more nature-like and closer to its natural state.
	The ~~aim was~~ to slow down the current and produce suitable nesting habitats for the trouts and shelter places for the juveniles. Also versatility to the river bed was improved by digging few wider areas. Gravel was brought approximately 40 m3 and placed to the river in several places bed to ensure the nesting habitats for the migratory fish.		Trouts, grayling and macro invertebrates will benefit from the restoration and not only in the river but also in the nearby lakes. The rivers in the area are straightened for log floating since 1900 century. Also the natural state in the rivers are altered because of intense forestry and bog drainage.

			The restoration plan was accepted 4.3.2011 and the work started immediately. The plan was restore six rivers in the area. The area is highly appreciated among the fly fishers and its very popular recreational area.
