Lac du Chambon, Reservoir in Isère, France

The artificial lake covers 1.4 square kilometers at an elevation of 1040 meters in the French Alps, containing 54 million cubic meters of water.

The construction of the Chambon dam started in September 1929 and finished in December 1935, forming this substantial water reservoir on the Romanche River.

The reservoir submerged three historical hamlets: Chambon, Dauphin, and Parizet, which reappear when the water level drops for maintenance operations.

The recreational complex provides rental equipment for water activities, including canoes, kayaks, paddleboards, and pedal boats, along with facilities for various sports.

The water level reduction during maintenance reveals the remnants of former settlements and an old road at the bottom of the valley.
