Site description A lake, c.15 km long, which was isolated from the Gulf of Bothnia by land elevation. The shallow waters have favoured the spread of Scirpus and Phragmites, which almost divide the lake in two at one point. Floating vegetation is also extensive and parts of the south-western end of the lake have been invaded by Salix scrub.

Key Biodiversity The area is important as a resting area for migrating geese, ducks, raptors and waders. 210 species of bird have been recorded.
