History
The lake was created to control water flow after disastrous floods caused severe damage and loss of life in 1843 and 1856. First proposed in 1895, construction started in 1955 and was completed by 1961.
During construction of the lake, approximately of material was moved. The dam was constructed and the valley slowly became a lake, flooding some villages in the process. This flooding is the subject of

The dam's effects go beyond only the lake itself. It serves as a focal point that supports the functioning of a vast hydroelectric infrastructure network. In Southeast France, this network consists of 15 hydroelectric facilities that are carefully placed along the Durance and Verdon rivers. The combined capacity of these linked plants, which totals 2,000 MW, makes a substantial contribution to sustainable power generation and the region's energy landscape.
