Dams

The Girotte dam was built in 1946. It was the first in Beaufortain. It is one of the rare dam to be filled with the water coming from "Tré la Tête" glacier next to the Mont-Blanc. That is why the color of her water can be so special green.

Built between 1962 and 1967, the Gittaz Dam can store 13 million m3 of water, its arched-gravity structure with triangular base uses its own weight to withstand the force of the water.

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.

Along with the dams of Gittaz and Saint Guérin, the Roselend Dam feeds the hydroelectric plant of La Bâthie. Located in the heart of the mountain pastures, near Mont Blanc, it is a beautiful site for fishing and hiking. This is the 4th highest dam in France.
