The Grand'Maison is an embankment dam with a height of 140 m (459 ft) from the riverbed and 160 m (525 ft) from foundation. It is 550 m (1,804 ft) long and has a fill volume of 12,000,000 m (15,695,407 cu yd). The reservoir withheld by the dam,

located lower in the valley is the lower reservoir. The dam was constructed between 1978 and 1985 with its power station being commissioned in 1987. With an installed capacity of 1,800 MW, it is the largest hydroelectric power station in France.
