Site details
Site description: 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).
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: This is an important roost for geese Anser from surrounding feeding areas, but counts underestimate numbers. The average seasonal peak number of waterbirds during 1992-1996 exceeded 20,000.
Delineation rationale: 9 March 2017: name and area edited. Now equal to the designated Special Protection Area (Birds Directive).

Threats
Summary of threats to biodiversity at KBA: The main threats are nutrient pollution (as at site 039, but problems are greater here as the lake is shallower), commercial reed-harvesting (`Other' threat, above), disturbance caused by wildfowl hunting, and the construction of a storm-surge barrier on the west side at Ramspol.
