The desire to establish a dam to tame the tumultuous waters of the Durance dates back to the 19th century. The creation of the lake marked the beginning of significant economic and tourism growth for the region. The site has quickly become an essential tourism destination in the Southern Alps. This work therefore makes Serre-Ponçon one of the largest artificial lakes in France and one of the largest earthen dams in Europe.
Constructed over six years and completed in 1961, the barrage flooded two villages - Savines and Ubaye. Climbing up past the barrage, you can see just how it as built to almost blend into its surroundings.
