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.
Built between 1955 and 1962, it required 942, 368m3 of concrete poured at a daily rate of 1,500 to 2,000m3. Arch-gravity structure and buttress type dam (150m high, length 804m). Surface of the reservoir: 320 hectares. Depth: 130m. Volume of the reservoir: 187 million m3. 2,600 workers worked day and night on the site in harsh conditions. The Ste Marie Madeleine Chapel was rebuilt on the shore of the lake before the impoundment of the dam. The Roselend hamlet was submerged on May 6th, 1960, and 15 of the 54 pastures were swallowed up. The Route des Grandes Alpes crosses this magnificent alpine site to join the Tarentaise valley (excluding during heavy snow, when the road is very narrow). This dam holds a reserve of renewable energy equivalent to 500 million Kwh.
From 15/05 to 15/10, daily.

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.
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.
1059 Points – The steep climb to the Col du Pré goes through the picturesque and protected hamlet of Boudin. We would recommend descending via the other side of the pass in order to see the beautiful Roselend Reservoir.
