The Saint Guérin Dam


Saint Guérin, patron saint of herds gave his name to the valley and the dam, which was built between 1957 and 1961. The dam contributes to feeding Lake Roselend through a connecting pipe between the reservoirs that operate in the manner of communicating vessels.

Its water surface is 50 hectares with a depth of 70m and a capacity of 13 million m3. Its arched-gravity structure measures 250m long. The reservoir receives each year the equivalent of twice its storage capacity.


From 06/05 to 22/10, daily.
