Lac de Vouglans

The Lac de Vouglans is the reservoir of the hydro-electric power station at Vouglans on the River Ain in the département of Jura in the region of Franche-Comté in eastern France. The dam, the Barrage de Vouglans is at coordinates 46°23′51″N 5°39′56″E / 46.3975°N 5.66556°E / 46.3975; 5.66556 (Barrage de Vouglans).

Description

The lake lies on Jurassic rock crushed into north to south ridges by the Alpine orogeny. It is therefore long and narrow, though rather sinuous in plan. It is about 30 kilometres long though only 21 km in a straight line. It lies in the valley of the Ain, impounded by the dam at Cernon. The old village of Vouglans was displaced by its construction in 1968 by Électricité de France (EDF).

The buildings of the Carthusian monastery of Vaucluse were also moved to make way for the rising waters.

The lake is arranged for tourism with view-points scattered through the woods which cover the hillsides along its shores and places set up for bathing and boating.

The annual mean flow of water at the dam is 40.80 cubic metres per second.
