Lac de Serre-Ponçon, Artificial lake in Hautes-Alpes and Alpes-de-Haute-Provence, France.
The Serre-Ponçon reservoir spans 28 square kilometers between mountains, containing 1.27 billion cubic meters of water from the Durance and Ubaye rivers.
Construction of the dam started in 1955 following devastating floods in 1843 and 1856, requiring the relocation of several villages before completion in 1961.
The Chapel Saint-Michel, dating from the 12th century, stands on an island within the lake, becoming accessible by foot during low water periods.
The reservoir generates 380 megawatts of hydroelectric power while providing water management and recreational activities like swimming, sailing, and fishing.
The dam structure reaches 123 meters in height and supports a network of 15 additional hydroelectric plants along the Durance and Verdon rivers.

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.
