Lac du Bourget, Natural lake in Savoie, France
The lake extends 18 kilometers in length and 3.5 kilometers in width, reaching depths of 145 meters in certain sections.
The formation of Lake Bourget occurred during the Würm glaciation period, creating the largest natural water basin located entirely within French territory.
Writers from different periods have drawn inspiration from the lake, with poet Alphonse de Lamartine dedicating several verses to its waters.
The lake maintains 14 ports with over 2,600 sailing berths, offering facilities for various water activities including kayaking, rowing, and wakeboarding.
The lake's meromictic characteristic prevents the mixing of deep waters with surface waters throughout the annual cycle.

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.
