Situated at an altitude of 1,255 metres near Col des Mosses in the Lake Geneva Alps, Barrage de l’Hongrin is not only a major water reservoir used to produce electricity, but also an impressive site for walking and fishing.
Built towards the end of the Sixties, Barrage de l’Hongrin collects thaw water in 9 waterways, as well as water from Lake Geneva pumped through underground galleries of a length of some twenty kilometres.
This vault dam consists of two curvatures with a height of 95 m and 123 m respectively, on which visitors can walk along in all safety. The reservoir can hold a maximum of 52 million cubic metres of water distributed over a depth of 105 m and 160 hectares, ideal for fishermen and swimmers.
The Hongrin artifical lake is surrounded by pastures and herds of grazing cattle. Their bells resound for miles around conferring a peaceful atmosphere to the site, as well as adding a touch of Alpine life and folklore when you hike or bike in the region.
