The Mjörn is a lake in Västergötland , Sweden . The lake was first mentioned by name in 1350 under the name Mior .

location

Its 55 km² area is located in the municipalities of Lerum and Alingsås . Mjörn is the second largest lake in Västergötland, if you do not count the two large lakes Vänern and Vättern . Due to the unregulated water level, this sometimes varies by up to 2 m. About 60 islands and skerries of Mjörn have their own names.

The lake is fed by the lakes Ålandasjön and Anten to the north and the Säveån river , which runs through the lake and also forms the outflow at Norsesund .

fauna

The lake is home to a large number of fish and bird species. In addition to specific fish species such as alpine bullhead , lamprey and Mjörnforelle also there are perch , pike , perch , eel , bream , roach and other species in the lake.

Due to the relative proximity to the sea, there are also marine bird species on the Mjörn, including the great-tailed gull , oystercatcher and eider . Some of the islands in the lake are bird sanctuaries.
