The barrage 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 vannes secteur (sluices). These were replaced by 3 vannes-clapet (rising barriers), 6.2 by 40 metres (20 ft × 131 ft) in dimension. These gave the dam capacity to cope with crues (floods) of up to 4 400 m3/s.[2]
The lake
The barrage raises the level of the Tarn by 40 m and the lake formed, the Lac de Pinet, is at an altitude of 320 m and has a surface area is 1.09 km². 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 barrage, it contains five Francis turbines which generate 42.5 megawatts (57,000 hp).[3]
