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.

Moiry
Grimentz Val d'Anniviers Switzerland
The Moiry Dam at the head of the Grimentz Valley was brought into service in 1958. It is not the most impressive of the Valais works but the panorama of the turquoise waters of the lake and the Moiry Glacier as seen from the path that leads to the summit of Sasseneire (3254 m) is arresting. The dam, like the glacier, is accessible by private car or postal bus. It is open from June to October, weather permitting, but closed in winter. Tours are available in the summer and offer information about the building and operation of the Moiry dam. Moiry
