Grasbroek is a locally well-known dive site. A line from the corner of the pier leads to the underwater house Arcadis, with a 5-meter platform above it. From the mainline, several other lines branch to other objects. Max depth is 12m.
From common to more rare: gobies, perch (Perca fluviatilis), crayfish, pike (Esox lucius), pikeperch (Sander lucioperca), and even an elusive sturgeon.
