 Only a few tree stumps that jut out of the water, indicate that it was temporarily dry land.The lake is part of the protected area known as the North Rügen Bodden and Nonnensee ("Nordrügensche Bodden und Nonnensee") and is a breeding place and sanctuary for many bird species as well as a recreation area for the nearby town.For example, a five kilometre long circular path runs around the lake with benches and two bird hides from which the rich variety of bird life can be observed.
