Site description
A shallow (1-4 m in depth) nutrient-rich lake at the head of the Gulf of Bothnia, formed when rising land isolated a bay from the sea. Fine marine sediments with overlying mud deposits cover the lake floor. Water exchange is minimal due to the low rate of inflow to the lake. Large sections of the shoreline are marshy, with Phragmites, Typha and Equisetum present; the lake itself supports floating vegetation. Mixed forests surround the lake.

Key biodiversity
The IBA is important for breeding waterbirds, waders and gulls.
