Status of finnish lakes and rivers about the same as before, coastal waters have deteriorated

A new assessment of the ecological status1) of surface waters in Finland shows that 87% of the surface area of our lakes and 68% of our rivers are in good or very good condition. Eutrophication is still the most significant problem. There have been no major changes in the status of inland waters since 2013, except for some improvement in certain sites. The status of the Gulf of Finland has improved, but for the most part the status of coastal waters is not good. The risks associated with groundwater have not increased.

The preliminary assessment covered 6,875 lakes, rivers and coastal water bodies. The Centres for Economic Development, Transport and the Environment and the Finnish Environment Institute will examine the causes of the changes in certain individual sites during this autumn.
