	\|Project summary=The River Keskijoki is 1 800 meters long and it flows though forest areas from the Lake Yli-Soppanajärvi to the Lake Soppanajärvi. The river bed is mainly sand and contains rocks and gravel~~. A big part of the river is marked as nature conservation area~~. The water quality in the river is good or very good.		\|Project summary=The River Keskijoki is 1 800 meters long and it flows though forest areas from the Lake Yli-Soppanajärvi to the Lake Soppanajärvi. The river bed is mainly sand and contains rocks and gravel. The water quality in the river is good or very good.

	The Centre for Economic Development, Transport and the Environment for Lapland restored three sections in the river. 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. 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 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.

	The lenght of the first restored area is 545 meters and the width is 8 in average the area in total was 4 360 m2. The Second was 150 meters long, width 8 meters and the area in total was 1 200 m2. The restored rapid area in the totally was 1900 m2. The thirds section was 200 meters, width 5 meters and the area was 1000 m2.
