Lake Aiguebelette is a natural lake located in France in the Savoie department in the Auvergne-Rhône-Alpes region. Main lake of the Savoyard Avant-Pays, in the southern end of the Jura massif, it is located approximately 10 kilometers from Chambéry, approximately 40 kilometers from Grenoble and approximately 100 kilometers from Lyon. It has an area of 545 hectares and is as such the seventh natural French lake after Lake Geneva (in part), Lake Hourtin and Carcans, Lake Grand-Lieu, Lake Bourget, Lake Annecy and Lake Marville (at Kerguelen). Bordered to the east by the Épine chain which culminates with Mont Grelle at 1,427 meters and to the west by Mont Tournier, its maximum depth is 71 meters. At first glance, it is characterized by its often green color, whereas, in the same region, Lake Annecy is bluer and Lake Bourget is more often steel gray. Lake Aiguebelette is a private lake which belongs to the Rivérieulx de Chambost de Lépin family and Électrcité de France, who have entrusted its management to the Communauté de Communes du Lac d'Aiguebelette. Its banks are shared between five riverside municipalities: Aiguebelette-le-Lac, Lépin-le-Lac, Saint-Alban-de-Montbel, Novalaise and Nances. In the southern part of the lake there are two islands, surrounded by reed beds. In order to preserve the quality of its waters and its environment, thermal motor boats have been prohibited on the lake since a decree of 1967. It has also been the first regional freshwater nature reserve in France since March 2015. Source: Wikipedia
