The Plate Taille dam is the largest hydraulic structure in Belgium by both surface area and volume.
The reservoirs were engineered to manage water deficits in the Sambre basin during summer drought periods.
The complex includes a vertical turbine installation capable of pumping water back up to the reservoir during periods of low energy demand.
The lake system covers a total water surface area of approximately 6.17 square kilometers.
The site hosts a specific zone designated for scuba diving which includes submerged training platforms.
The dam's structure incorporates a hydroelectric power station at its base.
The Eau d'Heure lakes comprise a complex of five interconnected artificial reservoirs located between the provinces of Namur and Hainaut in Belgium. These lakes were primarily constructed for hydroelectric power generation and to regulate the water levels of the Sambre river. The site covers approximately 600 hectares, serving as the largest nautical recreational area in Belgium. Visitors access a variety of aquatic activities, including sailing, windsurfing, jet skiing, and scuba diving, across the Plate Taille, Eau d'Heure, Falemprise, Féronval, and Ry Jaune lakes. The Plate Taille lake features the largest dam in Belgium, measuring 107 meters in height. A specialized center allows for year-round indoor and outdoor water sports. The area is integrated into a landscape of woodlands and cycling paths that facilitate access between the distinct basins.

Bring a wetsuit if planning to engage in water sports, as the reservoir water temperatures can remain low even in summer.
Rent bicycles on-site to navigate the paths between the five lakes, as the complex is too vast to explore entirely on foot.
Check local wind forecasts before visiting if your primary goal is sailing or windsurfing.
Attempting to swim outside of designated beach zones, as sudden depth changes and underwater infrastructure present safety risks.
Water sports centers and some recreational facilities observe seasonal operating shifts, with peak availability between April and October.
Maintain noise levels in designated nature preservation zones; obey marked safety buoys in swimming and boating areas.
