Lake Eupen is an artificial lake near Eupen in East Belgium, not far from High Fens. The lake is created by a dam which was built on the river Vesdre in 1938 but inaugurated only in 1950[1] by Prince Charles of Belgium. The area has a German-speaking population who refer to the river Vesdre as Weser, but which is distinct from the Weser river in North Germany.
