Construction took place from 1922 to 1926 and, at the time, was the largest dam in Europe.
The water behind the dam creates the Chambon Lake which, at 312 hectares, is the largest body of water in the region, and is popular with watersports enthusiasts.
Electricity generation is via six valves, with a power of 12 MW each, giving an annual electricity production of 101 million kWh.
