Viewpoint over Vouglans lake

Built on the Ain, at 130 metres high, the Vouglans dam is the French dam with the 3rd highest storage capacity: it is capable of holding around 600 million cubic metres of water, and with 1600 hectares of water surface, it makes the Vouglans lake one of the largest artificial lakes in France. It took a year and a half to fill with water and it deeply changed the physiognomy of the Ain’s embankments, swallowing up several hamlets as well as the Chartreuse de Vaucluse, the first Carthusian monastery in the Jura (12th century).
