Keeten-Mastgat

The Keeten-Mastgat is a river of the Netherlands. It used to be an estuary of the Rhine and Meuse rivers, but today it is only connected to the Oosterschelde. It still receives some water from its former tributaries, but only when the Krammer-Volkerak receives too much water from the Hollands Diep.
