 In summer, the water often develops an algae buildup, so the lake must occasionally be closed to swimmers.The lake and the nature reserve were created by sand extraction during the development of the A 27 motorway and the construction of the university.The bus stops of "Wetterungsweg", "Campingplatz", and "Stadtwaldsee" on bus line 28 of the Bremer Straßenbahn AG are all near the northwest shore of the lake.
