Roselend dam

The 4th highest dam in France

Its construction spanned between 1955 and 1962, and engulfed the hamlet of Roselend and more than 50 mountain pastures. The reservoir created represents 320 hectares. It is fed by several rivers. Only the chapel of the hamlet, dedicated to Sainte-Madeleine, was rebuilt identically in height before the impoundment of the dam. Today it is located on the shores of the lake. Along with two other additional dams, the Roselend dam supplies the Bâthie underground power station. The homes of 450,000 people are thus supplied with entirely renewable electricity. In 2011, the dam celebrated its 50th anniversary. Drained in the spring, it then underwent an anniversary inauguration ceremony marked by many events: concert, ball, fireworks, numerous workshops, initiation to rowing, or even baptisms of ballooning and paragliding. The Roselend dam is reputed to be one of the most aesthetic in Savoy.

Practical information about the visit

The Roselend dam is located on the territory of the municipality of Arêches-Beaufort. To get there from the Idéal campsite, 60 km away, it will take you about an hour via Albertville. Given the altitude of the site, the road to the dam closes on the arrival of the first snow and until the snow melts. It is therefore possible to visit the Roselend dam every day from May 15 to October 15. Individual visits are free. Group reception is possible, with a visit lasting approximately one hour. The interior of the dam cannot be visited. Parking is available on site as well as toilets. There is also a restaurant service and a picnic area. The banks of the lake are popular for fishing and offer magnificent hiking trails. From the dam, be sure to take a stroll to Roselend Chapel.
