The Eau d'Heure lakes is a complex of five artificial lakes in Wallonia, forming the largest lake area in Belgium.
The dams were built during the 1970s. The lakes are not far from the village of Cerfontaine, 50 kilometres south of the city of Charleroi, and the border with France. They are within the municipalities of Cerfontaine and Froidchapelle.
The primary river feeding the lakes is the Eau d'Heure. There are five dams and one hydro-electric power station.
