Mountain reservoir

Lac de Léchereuse

In order to guarantee the snow from the opening until the end of the season, Télé Champéry-Crosets Portes du Soleil SA has built a hillside reservoir. This means a complete restructuring of the technical snowmaking network.

Thanks to this reservoir, and in order to respect the ecological balance, the water withdrawal will not increase but the production time will decrease because the necessary stock will be available at all times!
