In the autumn of 2013 the wetlands belonging to the former inundation sluice near S.E.-Beemster in the province of Noord-Holland were surveyed for the presence of freshwater snails. Galba truncatula was found at the base of the interior of the sluice, two other species were found in a shallow drainage ditch. The latter two species were also found in the main basin (an artificial small lake), together with five additional species.
