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.
The Emosson reservoir, situated above the Trient Valley, was brought into service in 1972 to satisfy a high demand for electricity from all over the French-speaking part of Switzerland. Its waters come from the old submerged Barberine dam, erected between 1921 and 1925. It is a popular excursion destination, notably for the dinosaur trail close by. It can be reached by road and by taking the funicular which was used during the construction of the dam.
