Dam of Vieux-Emosson
The Vieux-Emosson dam was built in 1955 by the CFF.
At the same time as the construction of the Nant-de-Drance pumped-storage hydroelectric power station, it was raised by 20 metres in order to double the capacity of the water reservoir.
It is now 65 metres high and has a maximum water volume of 25 million m3.
