Lac de Coiselet, reservoir in France
Lac de Coiselet is a reservoir in the Ain region of the Jura, created in 1970 when a dam was built. The lake is surrounded by high cliffs and fed by two rivers, the Bienne and the Ain.
The lake came into being in 1970 following dam construction and served as a major infrastructure project for the region. Its creation allowed water storage and opened new opportunities for fishing and recreation.
The lake's name reflects local geography and usage patterns. Today, residents and visitors use the area as a peaceful retreat where fishing, walking, and simply sitting by the water form part of the local rhythm.
The shoreline is accessible via several walking trails that encircle the lake and offer different viewpoints. Swimming is not permitted, but fishing is a popular activity with good access points around the water.
The lake was created just two years after the nearby Vouglans reservoir, making it a relatively recent addition to the region. Despite its modern origins, it has become integrated into the surrounding landscape and feels like a natural part of the Jura.
