Non-glacial lake, but artificial, filled in 1968 (Vouglans dam) swallowing the Wild Valley of the Ain river and three villages! But... superb body of water and protected region! To do: complete tour (80 kms), South 1/2 tour sometimes quite technical, and North 1/2 tour (fun), or even West coast from Orgelet-Plaisair or East side from Maisod - Coyron! Nice ride MC

Commissioned in 1968, the Vouglans dam retains the waters of the Ain to form the eponymous artificial lake, the third largest in France. The scope of the work impresses.
