The dam Chancy-Pougny is a Franco-Swiss hydroelectric dam on the Rhone.
Located on the border between Avully (not Chancy as its name might suggest), in the canton of Geneva and the town of Challex (not Pougny) in the department of Ain, it is operated by the industrial Services of Geneva and the national company of the Rhone. GTM France has provided length rods 3-5 m between M60 and M170 to strengthen the foundations of the dam in grade steel HTSR
