Grevelingen, Protected saltwater lake in Zeeland, Netherlands
Grevelingenmeer is a saltwater lake situated between the islands of Goeree-Overflakkee and Schouwen-Duiveland in Zeeland. The broad, shallow body of water provides space for boating, fishing, and wildlife viewing, with several harbors and mooring facilities around its perimeter.
The lake was created by the construction of two dams in the 1960s and 1970s as part of the Netherlands' flood defense system. This engineering project transformed a tidal estuary into an enclosed saltwater body.
The lake draws sailors, windsurfers, and divers who gather at harbors around its edge for recreation. These water-based communities have made the lake a place where people meet to pursue their passions on and around the water.
Several harbors including Ouddorp and Bruinisse provide access points with facilities for water sports and fishing. Visiting one of these ports is useful for learning about water conditions and renting equipment or booking activities.
A special lock completed in 1978 controls water exchange with the North Sea to maintain the lake's salt content. This engineering feature allows the water to remain dynamic and supports marine ecosystems within the lake.
