Rising nearVaux-sur-Sûre in theArdennes in southeastern Belgium, the Sauer flows eastwards and becomes the border with Luxembourg nearMartelange. It forms the border between Belgium and Luxembourg for 13 kilometres (8 mi) north of Martelange. West ofEsch-sur-Sûre it flows into an artificial lake, theUpper Sûre Lake created by theEsch-sur-Sûre Dam, which gives its (French) name to the Luxembourgishcommune ofLac de la Haute-Sûre. After flowing throughEttelbruck andDiekirch, the Sauer forms the border between Luxembourg and Germany for the last 50 kilometres (31 mi) of its course, passingEchternach before emptying into theMoselle inWasserbillig.
