Project summary

Edit project overview to modify the project summary.


The River Knipån is located in South-East of Sweden in Knipåns nature reserve which is also an important groundwater area. River Knipån is important reproduction area for trout, European greyling and also endangered species European River Mussle and European River Lamprey. The River Knipån has been restored to improve the conditions for migrating fish and other aquatic organisms. There has been f.ex. damremovals and other improvements done in the stream. Also lakes Furusjön and Knipesjön in the upstreams of River Knipån has been chalced in 1991 which has improved the water quality for fish, like trout, sensitive to acidification.
