The principle of the channeling of the Moselle was definitively acquired when on October 27, 1956 the plenipotentiaries of the three riparian States, France, Germany and Luxembourg, signed the international convention on the development of the river. The Contracting States have decided to develop the Moselle between Koblenz (Germany) and Thionville (France) to make these 270 km (168 mi) of waterways accessible to boats of 1,500 tons. On May 26, 1964, the canalized Moselle was officially opened to navigation.

The Gréewemaacher-Wellen Dam (French: Barrage-écluse de Grevenmacher) is situated at kilometer 212.85 of the canal between the Luxembourg town of Gréewemaacher and the German town of Wellen. The lock for large ships is 170 m (558 ft) long and 12 m (39.3 ft) wide, with a drop height of 6.25 m (20.5 ft).
