The dam was built in 1932, and the station has five Francis turbines generating 42.5MW. The dam is 175 metres (574 ft) long and 41 metres (135 ft) high.[1]

Description

The dam

The dam constructed in 1929 was regulated by 18 groups of sluices. These were replaced by three rising barriers, 6.2 by 40 metres (20 ft × 131 ft) in dimension. These gave the dam capacity to cope with floods of up to 4,400 cubic metres (160,000 cu ft).[2]

The lake

The dam raises the level of the Tarn by 40 metres (130 ft) and the lake formed, the Lac de Pinet, is at an altitude of 320 metres (1,050 ft) and has a surface area is 1.09 square kilometres (0.42 sq mi) It lies in the communes of Saint-Rome-de-Tarn, Viala-du-Tarn and Saint-Victor-et-Melvieu.

The turbine hall

The turbine hall is 500 metres (1,600 ft) downstream from the dam. It contains five Francis turbines which generate 42.5 megawatts (57,000 hp).[3]
