Génissiat Dam
The 128th tallest dam in the world
The Génissiat Dam (French: Barrage de Génissiat) is a hydroelectric dam on the Rhône in France near the village of Injoux-Génissiat. Construction began in 1937, but was delayed by World War II, and the dam did not start generating power until 1948. By 1949 it had the greatest capacity of any dam in Europe.
