Lake Rusałka was created in 1943 by damming up the Bogdanka River. The reservoir covers and area of 36.7 hectares and reaches a depth of 9 metres. The shoreline is 3300 metres long with a bathing beach located on the northern side.
The lake is a typical zander fishing venue operated by the Polish Angling Association.
Close to the lake is the Golęcin forest area; walking trails wend their ways through alder woods and riparian strips. The barracks near the lake feature the Museum of Armoured Weapons with the famous "Rudy' tank known from the TV series Czterej pancerni i pies [Four tank crewmen and a dog].
