The 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 180 meters. 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 190 MW La Bâtiaz Power Station, 12 km (7 mi) to the east in Martigny, Switzerland. The drop between the dam and La Bâtiaz Power Station is 1,400 m (4,593 ft).

The largest mountainous cirque in the Alps, with impressive walls and waterfalls. Commonly around a 10km/300m altitude gain round-trip, but also longer (towards Lake Vogealle, 20km/1000m) or shorter 5km (for kids) are available.
