The Site, which is formed by artificial freshwater lakes created by the construction of dikes in the reclaimed IJsselmeer polders, is aligned with the Natura 2000 site boundary. The lakes receive their water from the Rhine and Ijssel rivers. The Site is of international importance for endangered bird species such as bittern, spotted crake and great reed warbler. It regularly supports more than 20,000 wintering waterbirds, with an average peak number of over 21,000 between 2005/2006 and 2009/2010. The Site also supports more than 1% of the individuals of the northwestern European population of Gadwall. The lakes play an important role as water reservoirs for irrigating the surrounding agricultural land, while they are also used for boating, commercial fisheries, shipping traffic, water management and sand extraction. Serious threats are posed by reed cutting, aquaculture, pollution with nutrients increasing eutrophication, and the construction of a sludge depot.
