river in eastern Belgium (province of Liège).From its source at
Losheimergraben on the Belgian-German border, it flows roughly west
about 50 km, across the south of the Hautes Fagnes region.It passes
through the town of Malmedy, and the artificial lakes of Robertville and
of Bütgenbach are formed by dams on the Warche.It is a right tributary
of the river Amblève, which it joins east of Stavelot.In the past the
Warche used to flow northward from Bevercee, following the current Trô
Maret valley, to continue through the current Eau Rouge valley. This
last valley is much larger than can be expected from such a small flow,
still representing the original Warche valley. In that time the Warche
confluenced with the Amblève at Stavelot. Later on, probably during the
last ice age the Warche adopted its current position, flowing through
the Malmedy graben.
