The lake was used as a landing site for seaplanes during the interwar period, such as the first regular passenger planes between Gotland and mainland Sweden 1933–39,[3] and a stopover on the Stockholm/Lindarängen - Danzig line, serviced by the AB Aerotransport in 1925–26.

[4] During the 1120s, a 170 by 170 m (560 by 560 ft) square timber platform was built in the middle of the lake.

On the platform was a number of closely built wooden houses.

The remnants of this construction, known as the Bulverket, are still present on the bottom of the lake.

It contains pike, perch, ruffe, roach, bleak, tench, rudd and carp.
