A freshwater lake with extensive reedbeds, bounded in the north by the dyke of Noordoostpolder (reclaimed in 1942) and in the south by the mainland (province of Overijssel). The Zwarte Water river (090) flows into the lake in the north-east corner, and the site is adjacent to Lake Ketelmeer (039) in the west (Ramspol). The north-eastern border is close to De Wieden (065). There is a shipping lane (dredged). This site, together with site 047, formed part of a single, larger site (former site NL028) in the previous pan-European IBA inventory (Grimmett and Jones 1989).
