The Nieuwe Maas is a significant tidal river and distributary of the Rhine, flowing approximately 24 kilometers west through Rotterdam in South Holland, Netherlands. It begins at the confluence of the rivers Noord and Lek and ends near Vlaardingen where it meets the Oude Maas to form the Scheur, which continues as the Nieuwe Waterweg. This urban estuary serves as a major navigation channel to the Port of Rotterdam and functions as a dynamic, brackish water fishery influenced by tidal flows from the North Sea.
