AN EXCEPTIONAL ALPINE ENVIRONMENT
WATERFLOW- 1,2,3 DAMS
The Emosson dam, the second largest water reservoir in Switzerland, is one of three structures on the site, which also includes the Vieux-Emosson dam and the Barberine dam, which was visible until the beginning of the summer and then drowned under the waters of Lake Emosson.
Emosson DAM (1935M)
Emosson, the second largest dam in Switzerland!
Vieux Emosson DAM (2205M)
The Vieux-Emosson dam was built in 1955 by the SBB.
In parallel with 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.
Visible until the beginning of summer, then drowned under the waters of Lake Emosson.

Châtelard hydroelectric factory.
Visit the Power Plant and Museum
Commissioned in successive stages between 1923 and 1928, due to the constant increase in electricity consumption, the SBB began to collect water from the Vallon d'Émaney in 1952 and then built the Vieux-Émosson dam. In 1972, the SBB built a second hydroelectric plant. The water of Émosson is also used to feed the electric plant of Vernayaz.
The Swiss Federal Railways (in collaboration with several partners) are currently working to connect the two reservoirs of Emosson and Vieux Emosson to the Nant de Drance pumped storage plant.
Guided tours for groups of up to 15 people are available by reservation, Monday to Friday, during the day. No guided tours are offered on weekends.
These visits are free.
