Vieux Emosson dam (2205m)

The Vieux-Emosson dam was built in 1955 by SBB (Swiss Federal Railways). In parallel with the construction of the Nant de Drance pumped-storage hydroelectricity plant, the dam wall has been raised by 20 metres in order to double the dam's storage capacity. The wall now stands 65 metres high, and has a maximum capacity of 25 million cubic metres.
