Water source of Luxembourg


Luxembourg has a number of minor rivers, such as the Eisch, the Alzette, and the Pétrusse, but the main river is the Moselle with its tributaries-the Sûre and the Our. Together, their courses serve as a natural boundary between Luxembourg and Germany. Along their banks, many of the country's medieval castles can be found.


The Moselle actually rises in northeast France and flows north through Luxembourg for 19 miles (31 km) to join the mighty Rhine at Koblenz, Germany. The Moselle is 320 miles (510 km) long, and is navigable, due to canalization for 40 miles (64 km). Green slopes, covered with vines, flank the meandering course of the river.

Rising in Belgium, the Sûre River flows for 107 miles (172 km) in an easterly direction through Luxembourg and into the Moselle. Its sinuous course essentially cuts Luxembourg from east to west. The Our River, flowing along the northeastern border, is a tributary of the Sûre. Its valley is surrounded by unspoiled countryside.

The Upper Sûre lake is the largest stretch of water in the Grand Duchy. Surrounded by luxuriant vegetation and peaceful creeks, the lake is a centre for water sports, such as sailing, canoeing, and kayaking. Such outdoor activities, which has made it an attractive spot for tourists, have led to the growth of a local crafts industry.

The town of Esch-sur-Sûre nestles at one end of the lake. Immediately above it, the river has been dammed to form a hydroelectric reservoir extending some 6 miles (9.7 km) up the valley. The Upper Sûre dam was built in the 1960s to meet the country's drinking water requirements.
