The Site is a stagnant freshwater lake which is separated from the Oosterschelde estuary by a dam constructed in 1986. It forms a hydrological unit with Ramsar Site Krammer-Volkerak (Site no. 747) through the Rhine-Schelde canal. The Ramsar Site boundary has been adjusted to the Natura 2000 boundaries and the Molenplaat area, although it is not included under Natura 2000, has been maintained within the Ramsar Site. Recreational land and a dike have been excluded. The wetland is in the process of changing from a marine tidal system into a stagnant freshwater lake resulting in changes in the flora and fauna composition. The Site is of international importance for threatened breeding waterbirds such as the Mediterranean gull, common tern and avocet. It also supports more than 1% of the individuals of the North-West European population of the gadwall. The primary human activities relate to boating, commercial fisheries, shipping traffic, tourism, dairy farming and water management. The main threats affecting the ecological character of the Site include non-industrial pollution leading to an increase in eutrophication and intensive livestock grazing.
