Lac de Monteynard-Avignonet, Artificial reservoir in Isère department, France
The turquoise waters of Lake Monteynard-Avignonet stretch for 20 kilometers through the Drac and Ebron rivers, reaching depths of 115 meters.
The creation of this reservoir in 1961 resulted from the construction of a 145-meter-high dam by Électricité de France for hydroelectric power generation.
The lake features two remarkable suspension bridges inspired by Himalayan architecture, connecting hiking trails between the Trièves and Matheysine regions.
The Treffort water sports center provides equipment and training for windsurfing and kitesurfing activities, taking advantage of the lake's frequent thermal winds.
Recognition as Europe's second windiest lake stems from temperature differences between water surface and surrounding mountains, creating strong afternoon thermal currents.

The lakes of Auvergne-Rhône-Alpes showcase remarkable geological diversity. The natural glacial lakes such as Bourget and Annecy contrast with the deep volcanic lakes of Pavin and Bouchet. The artificial lakes of Serre-Ponçon and Monteynard complete this hydrographic network. This region includes high-altitude lakes in the Alps and the Massif Central, plains water bodies, and hydropower dam reservoirs.
