The lake is located at the north end of Gotland, 0.4 km (0.25 mi) from the Baltic Sea.

[4] Most of the lake is surrounded by a 0.5 to 1 m (1.6 to 3.3 ft) high wall of gravel and larger blocks of stone known as a "beach barricade".

[1] It is inhabited by species such as northern pike, perch, roach, rudd, tench, European bullhead and whitefish.

A number of rare lichens and polyporales can be found in the nature reserve surrounding the lake, along with the land snail Cochlicopa nitens.

[4] The lake's outflow in the north was dammed up and led through a culvert for production of hydroelectricity following a decision in 1939.
