Slijk-Ewijk Noord Plas is a freshwater dredge hole in Gelderland with a sandy bottom, shallow clay fossils, and a shallow east side that works well for beginners and snorkelers. The west side slopes into deeper water with clay blocks and walls, so the site gives you an easy entry profile with more structure as you swim out. Fish life is a highlight, and the lake is also popular with anglers on the north side.
