The lock, designated as the Sluis van La Plate Taille, was built as part of a large-scale water project developed in the second half of the 20th century. This project aimed to buffer water, prevent floods, create drinking water reserves, and provide a stable basis for energy production through hydropower. The lock allows water to be moved in a controlled manner between different levels and compartments of the lake system. Technically, the lock functions on the principle of water level regulation between two basins with different levels. Using sluice gates and lock doors, water can be slowly let in or drained, allowing ships (where applicable) or water masses to be moved safely without sudden pressure differences. In this specific case, the emphasis is less on shipping and more on hydrological control within the reservoir complex. Its location at La Plate Taille is hydrologically strategic. This lake serves as a central reservoir within the Lacs de l’Eau d’Heure and directly influences the water balance of the surrounding region. The lock helps regulate water levels, especially during heavy rainfall or dry periods, thus supporting the broader water management system. Ecologically, the lock indirectly contributes to the management of the ecosystem in and around the lakes. Controlled water movement affects the quality and distribution of water, which in turn impacts fish populations, aquatic plants, and bank vegetation. Managing the water level is therefore not only a technical but also an ecological responsibility.

@Nicolas Yes, it's generally quite flat along the water's edge. From the lake, it's possible to go back up towards Olloy-sur-Viroin. If you're looking for a bit of elevation gain, you should find what you're looking for there 😅
