Grandval Dam, Dam in Cantal, France
Grandval Dam is a concrete dam on the Truyère river in the Cantal department of France. It stands 376 meters long and holds back a reservoir, with a power station at its base.
Built between 1955 and 1960, the dam was designed by engineer André Coyne and architects Henri and Louis Marty. It was part of a broader effort to harness the Truyère for electricity and flood control.
The dam's name comes from the nearby village of Grandval, which was submerged when the reservoir filled. Today, the dam is a local landmark where families come to picnic and watch the water release.
The dam is easily reached by car from nearby villages, with parking available near the viewing area. Visitors can walk along the crest for wide views, but should stay behind safety barriers and wear sturdy shoes for the uneven paths.
The dam's reservoir covers the remains of several old farms and a bridge that were abandoned before the valley was flooded. Low water levels sometimes reveal these remnants, offering a peek into the past.
