Description
The artificial lakes produced by the dams cover a large superficy (several square kilometres). The entire area is surrounded by trails and there are many excellent vantage points looking over the various lakes. Furthermore, there are many parking areas, bicycle rentals, and several restaurants around the lakes.
The largest and deepest lake is the westernmost Plate Taille, which in the winter frequently harbours uncommon species such as the Feketenyakú vöcsök, Jeges búvár, Sarki búvár, or Füstös réce. Hundreds of birds of more common species are present on the water at most hours of the day, such as Csörgo réce, Kontyos réce, and Fütyülő réce.
The southernmost lake Falemprise is commonly occupied in the winter by Kerceréce, Barátréce, and occasionnally small groups of Énekes hattyú.
The "middle" lake, l'Eau d'Heure proper, may have in addition to the above species stray individuals of the species Hegyi réce, Kis bukó, Nagy bukó or occasionally geese such as Nyári lúd and Nagy lilik.
The woods surrounding the entire area are also quite rich in species, including notably Csíz, Süvöltő, közép fakopáncs, and Csuszka.
The entire site is also replete with seagulls of various species and common waterfowl such as Tőkés réce, Kontyos réce, Szárcsa, Kendermagos réce and Kontyos réce.
Unfortunately because of the important disturbances by high tourism in the spring and summer, there is little to observe at those seasons.

It is a half hour drive from Charleroi, most notably through route de Philippeville and the N5. The entire site is surrounded by large paved paths that can be travelled on by foot or by bicycle, and numerous small parking areas allow travel by car between distant areas of the lake for easier observation.
