About Barrage de Gréoux
A Brief History
Built in the mid‑20th century, Barrage de Gréoux (sometimes referred to as the Gréoux Dam) was designed to regulate the flow of the Verdon River, provide hydro‑electric power, and support irrigation for the surrounding agricultural lands. The dam stands 67 meters tall, a testament to the engineering expertise of its era, and its concrete structure stretches across the river’s gorge, creating a reservoir that now serves both functional and recreational purposes.
Significance
Beyond its practical role, the dam has become an integral part of the local landscape and identity. It supports renewable energy production, helps maintain water levels for downstream ecosystems, and offers a serene setting for outdoor activities. The reservoir’s calm waters reflect the surrounding limestone cliffs, making it a favorite spot for photographers and nature enthusiasts alike. Moreover, its proximity to the historic spa town of Greoux‑les‑Bains—renowned for its thermal springs—adds an extra layer of cultural richness to the visit.
