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.
