The Plate-Taille Dam is located in southern Belgium in Wallonia, on the border of the provinces of Namur and Hainaut. The dam is situated near the villages of Froidchapelle and Cerfontaine and forms the central element of the Lacs de l’Eau d’Heure lake district, the largest artificial lake complex in the country. This area covers approximately 1800 hectares and consists of several interconnected lakes that together form a unique landscape of open water, wooded hills, and extensive recreational zones. Due to its location between the Ardennes and the Fagne, the area has a varied and gently rolling terrain. The origin of the dam dates back to the 1970s when Belgium faced water management problems. The Sambre River, an important waterway for industry and shipping, experienced highly fluctuating water levels. During dry periods, the water level dropped too low, which had economic consequences. To solve this problem, an ambitious project was launched, including the construction of a series of dams on the Eau d’Heure River and its tributaries. The construction of the Plate-Taille dam began around 1974 and was completed in 1981. As a result of its construction, five lakes were created: * Plate Taille (the largest and deepest) * Eau d’Heure * Falemprise * Ry Jaune * Féronval The construction brought about a major change for the region. Certain areas were submerged, and residents had to relocate. At the same time, this project laid the foundation for a new economic model based on tourism and recreation. The Plate-Taille dam is the largest dam in Belgium and an impressive example of modern hydraulic engineering. The Plate Taille lake itself has a surface area of approximately 350 hectares and is the largest and deepest lake in Belgium. The dam holds back an enormous mass of water and literally forms the heart of the entire lake district. One of the dam's main functions is energy generation through a pumped-storage power plant. * Capacity: ± 140 megawatts * Number of turbines: 4 (reversible) * Type: pumped-storage power plant System Operation The system operates on a clever principle: * During low energy demand, water is pumped to a higher reservoir. * During high energy demand, the water flows back down through turbines, generating electricity. This makes the plant particularly valuable for stabilizing the electricity grid, especially in combination with renewable energy sources such as wind and solar power. Around the dam lies a surprisingly rich nature reserve. The combination of water, forests, and open plains ensures great biodiversity. The landscape is characterized by: * Dense deciduous and coniferous forests * Open grasslands * Reed beds along the banks * Quiet bays and small islands Animals found here include: * Roe deer * Foxes * Waterfowl such as grebes and cormorants * Birds of prey The creation of the lakes has led to new ecosystems where flora and fauna have adapted to the water-rich environment. For someone who enjoys long and challenging hikes, like myself, this area is ideal, and you can easily create routes of several hours here without much crowds. 🚴♂️ Cycling and Recreation Besides hiking, the area is also popular with: * Road cyclists (hilly terrain) * Mountain bikers * Families (flat cycling paths around the lakes) There are well-maintained cycling routes that connect the entire lake district. 🚤 Water Sports and Activities The Lacs de l’Eau d’Heure are the center for water sports in Belgium. Possibilities: * Sailing * Kayaking * Windsurfing * Diving (in certain zones) * Swimming Motorized water sports are permitted to a limited extent, which contributes to a relatively calm and natural atmosphere. 🧭 Tourist Facilities The area is highly developed for visitors without losing its natural charm. Key attractions: * Skywalk Plate-Taille – a panoramic tower with views over the entire area * Natura Parc L’Eau d’Heure – adventure park with climbing routes and zipline * Marinas and beach areas * Holiday parks and campsites This makes the area suitable for both day trips and longer stays.

Via a short but tiring slope you reach a viewpoint on Lake Virelles, where you also have the Aquascope. Opposite the bench on the blue walking trail you can continue a few meters in the direction of the lake. There you have the best view, which is also marked on the map as a viewpoint.

AquaScope Virelles is a nature reserve in Virelles, Belgium, known for its rich biodiversity and educational programs. The center is also an excellent place for birdwatching, both for groups and individuals, and offers unique experiences such as a night in a hut by the water or a silent excursion at dawn on the lake. AquaScope Virelles is a gateway to the new National Park Entre Sambre Et Meuse and aims to raise awareness of nature and environmental protection. The AquaScope has a small restaurant and is therefore the ideal place before or after a walk in the area.

The AquaScope Virelles is located directly at the lake and invites you into direct contact with the protected fauna and flora thanks to different viewpoints and boardwalks along the water. Temporary exhibitions on the biotope, a water play area and of course the restaurant combine to make the AquaScope an ideal excursion location for families.
