Address:
Salvan 1925, Switzerland

Lac d'Émosson is a reservoir in the canton of Valais, Switzerland. It is located in the municipalities of Salvan and Finhaut. The closest small city in Switzerland is Martigny. The lake has a surface area of 3.27 km² and an elevation of 1,930 m. The maximum depth is 161 m. The purpose of the Émosson Dam is hydroelectric power generation. Water from the reservoir first powers the 189 MW Vallorcine Power Station downstream and just over the border in Vallorcine, France. Water is then sent through a headrace tunnel to the 162 MW La Bâtiaz Power Station, 12 km to the east in Martigny, Switzerland. The drop between the dam and La Bâtiaz Power Station is 1,400 m .The first dam of Émosson was built in 1925. The current dam with a height of 180 m was constructed between 1969 and August 1973 and floods the old dam. The reservoir was fully impounded on 10 September 1975, it increased the reservoir's volume from 40 million m³ to 227 million m³. The old dam can still be seen when the water level in the Lac d'Émosson is very low. The lake will serve as the lower reservoir for the 900 MW Nant de Drance Hydropower Plant which is expected to be operational beginning in 2018.In 1955, another dam was built 300m higher above the now existing lake. This lake is now known as the Lac du Vieux Emosson. The dam can be reached by road or by a funicular-train-funicular trip. The Chatelard funicular railway is the first used from the valley bottom, it is the steepest 2-cabin funicular railway in the world with a gradient of 87 percent.
