Dams and reservoirs
They are among the biggest, heaviest and most impressive structures in the Alps – the dams and reservoirs situated in the Valais mountains. The biggest of them can be admired during guided tours. Made by human hands, they serve as powerful testimony to the importance of hydraulic energy for a mountain canton’s economy. The Valais reservoirs will continue to play a significant role in the future – as Switzerland’s greatest source of renewable energy. A visit is sure to be an unforgettable experience.
With a capacity of 40 million cubic metres, this massive dam towers 52m in height and measures 40m in width at its base, with a 608m-long dam wall at its crest. It was commissioned in 1950. Situated at the foot of the Dents-du-Midi range above the Trient Valley, it can be reached in 1½ hour’s walk from the picturesque hamlet of Van, above Salvan - Les Marécottes. The dam’s reservoir forms the man-made Lake Salanfe, whose waters beautifully mirror the surrounding peaks. The dam is a popular destination, known for its superb alpine views and many walking trails.
