Ringkøbing Fjord
 Ringkøbing Fjord despite its name is in fact a shallow lagoon on the westcoast of Jutland. Skjern River terminates in Ringkøbing Fjord with a large river delta system to the east and the lagoon is shielded from the North Sea by a long isthmus named Holmsland Dunes to the west. On the Hvide Sande Canal in the middle of the isthmus there is a floodgate that provides access to the sea to the west. The fjord is about 30 kilometers long and 2 to 3 meters deep.
