Anyone hiking in the area around the dam encounters some of the signs of modern-day use of the Alps’ resources: roads around the works site, piles of gravel and so on. Here, water is used to generate electricity.
The hydroelectric power company Grande Dixence S.A. collects the water here and uses enormous pumps to raise it to an altitude of 2,400 m. The water then flows through tunnels bored through the interior of the mountains to the Lac des Dix. This reservoir is held in place by the world’s second-tallest gravity dam (285 m high).
