Lac de Saint-André, Protected lake in Porte-de-Savoie, France.
Located at the base of Mont Granier, Lake Saint-André spans 7.67 hectares with a depth of 14 meters, featuring wooden piers and nature trails.
The lake formed naturally on November 24, 1248, when a section of Mont Granier mountain collapsed, creating a depression that filled with groundwater and runoff.
The lake functions as a departmental protected site, hosting 216 plant species and 25 dragonfly species under conservation management by Savoie Nature Conservation.
Swimming is permitted exclusively in the designated leisure area, while fishing requires proper permits and adherence to seasonal opening times from March to December.
The lake contains three distinct zones: a natural reserve for wildlife protection, a fishing section with piers, and a recreational area for controlled activities.

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.
