Less than a mile from Esch-Sur-Sure is the 156 foot high dam at the western end of the Lake of the Upper Sure. On top of the dam is a road to the south side of the lake. This artificial, lovely lake provides drinking water for much of Luxembourg, and the three miles nearest the dam is a protected area. Swimming, fishing (permit required), windsurfing, canoeing and sailing are allowed on the remainder of the lake and these activities are very popular. No motorboats are allowed.
