The lac du Bourget (Lake Bourget) is a lake in the Savoie department of France. It is the largest and the deepest lake located entirely within France. The most important town on its shore is Aix-les-Bains. Chambéry, the capital of Savoie, lies about 10 km south of the lake. The lake is named after the town Le Bourget-du-Lac, on its south shore. It is mainly fed by the river Leysse (and other small rivers), and drains towards the river Rhône through the Canal de Savières, an artificial channel. It is a Ramsar site. The extinct bezoule was found only in this lake.
