Course[change | change source]

The Sauer near its source in Vaux-sur-Sûre

The source of the Sauer is, as Sûre, in the southeast of Belgium in the Ardennes (Luxembourg province), on the western part of the Rhenish Massif, at an altitude of about 510 m (1,673 ft).

From there, the Sauer flows to the east and crosses the border between Belgium and Luxembourg near Martelange. It forms the border between Belgium and Luxembourg for 13 km (8 mi) north of Martelange. On their way through the mountainous north of Luxembourg (the Oesling), it passes through the Lac de la Haute Sure, an artificial lake to the west of Esch-sur-Sûre.

After flowing through Ettelbruck and Diekirch, the Sauer forms the border between Luxembourg and Germany for the last 50 km (31 mi) of its course, passing Echternach before joining, as left tributary, the Moselle in Wasserbillig, at about 132 m (433 ft) of altitude.
