レコンタミンヌ-モンジョワの湖・トップ20

The Roselend Dam is located in the commune of Beaufort-sur-Doron, in the Beaufortain region of Savoie, between the Col du Pré and the Cormet de Roselend, near the Arêches-Beaufort ski resort. The surrounding mountains reach an altitude of around 2,800 meters. It is part of the Roselend La Bâthie hydroelectric complex, which includes the Roselend Dam and two satellite dams: La Gittaz and Saint-Guérin. This complex is managed by EDF's Alpes Production Unit. The Roselend La Bâthie hydroelectric complex produces the equivalent of the domestic energy consumption of 450,000 residents, thus avoiding the emission of 890,000 tons of CO2 per year. The Roselend Dam is a double-curved arch dam with buttresses. Height = 150 meters Crest length = 804 meters Water reservoir [of the hydroelectric complex] = 187 million m3 The Roselend - La Bâthie development is supplied by the Roselend dam itself, as well as by two satellite dams, La Gittaz and Saint-Guérin. The total storage capacity of these three reservoirs, connected by a system of galleries, is 213 million m3. The water collected at Roselend crosses the massif through a 12.5 km long gallery to flow at an altitude of 1,400 m into the Isère Valley, in the Tarentaise region. It is then transported to the underground plant at La Bâthie via a 2,500 m long penstock, with a drop of 1,200 m. The power plant is equipped with six Pelton-type generating units with a total capacity of 550 MW. Since 2013, EDF has been replacing the main components of each generating unit (turbine, generator, transformer, and energy evacuation cables) to achieve a total capacity of 600 MW by the end of 2018. https://youtu.be/G0Ss9v6wxQQ

One of the most visited sites in the Alps, on foot or by bike.

Steep and rugged climb. On the way back, follow the ski slope to the left. The descent is steep, but on soft, level terrain.

Great road with great view

Excellent welcome, with meal, coffee and dessert. Magnificent view of the peaks to the south: Pierra Menta, Roc de la Charbonnière, Pointe de Cerdosse, Mont Rosset.

Until about ten years ago the lake was much bigger and really beautiful, last year I saw it again and it left me a little disappointed. However, if you have never been there I recommend a visit!

This is a lovely little lake, in the heart of a breathtaking panorama of mountains and glaciers. An incredible place. The powerful lateral moraine of the Miage glacier obstructs the outflow from Val Veny, so a large marshy area has formed, partly rich in vegetation and with small water surfaces. Running on this path shared by the Tour of Mont Blanc and the Alta Via 2 of the Aosta Valley is extraordinary: not very technical, not excessively steep and with stunning views.

Lake Chécrouit is a small mountain lake located in the Val Veny at an altitude of 2,165 meters. On clear days, the majestic glaciers clinging to the rock spiers are reflected in this small body of water. A truly extraordinary show!
