Lake Annecy (French: Lac d'Annecy, [lak dansi]) is a perialpine lake in Haute-Savoie in France. It is named after the city of Annecy, which marks the start of the Thiou, Lake Annecy's outflow river.[1][2]: 958
It is the third-largest lake in France, after the Lac du Bourget and Lac de Grand-Lieu, if the French part of Lake Geneva, which is shared between Switzerland and France, is excluded.[citation needed] It is a popular tourist destination known for its swimming and water sports.[citation needed]
The lake was formed about 18,000 years ago, at the time the large alpine glaciers melted.[citation needed] It is fed by many small rivers from the surrounding mountains (Ire, Eau morte, Laudon, Bornette and Biolon) and a powerful underwater source, the Boubioz, at an 82-metre depth (269 ft).[citation needed]
