The Chambon Dam is a gravity dam type structure, made of Cyclopean concrete without reinforcements (except crowning and sidewalks), built between 1930 and 1935. It is 90ml high for a total length, at the 293ml crown level.


The upstream facing is vertical and shows a 5% inwards inclination in the current zone. The downstream facing is vertical on the upper 5 ml and then slopes to present an inwards inclination of 70% to 75%. The slope straightens to 23% in the lower part.
