Attert (river)

The Attert (French pronunciation: [atɛʁt], German pronunciation: [ˈatɐt], Luxembourgish: Atert) is a river in western Europe that flows through Belgium and Luxembourg. Approximately 38 kilometres (24 mi) long, it rises near Nobressart in Belgium, crosses the Luxembourg border, and ultimately joins the river Alzette at Colmar-Berg. The Attert basin covers around 290 square kilometres (110 sq mi) and features diverse landscapes influenced by regional geology, resulting in seasonal variations in water flow and sediment transport. Since 2001, Belgium and Luxembourg have jointly managed the river through ecological initiatives aimed at preserving water quality, protecting habitats, and supporting aquatic wildlife.

Flows through: Belgium.
