The Lac d'Icogne is a reservoir in the municipality of Lens near Crans-sur-Sierre , canton of Valais . The Icogne earthfill dam is located at the western end of the Crans-Montana plateau .
The lake is used to supply the municipality of Icogne with water . It is fed by Bergbach Partichioux. The lake also receives water indirectly from the Ertentse mountain stream through a water pipe that crosses the mountain (“Tunnel du Mont-Lachaux”, built in 1947), which irrigates the Plan-Mayens area. The lake overflow flows into the mountain stream Pontec. The lake has an area of 0.007 km².
There are plans to build a hydropower plant with an output of 988 kW for the lake overflow.
