The Bissorte Dam (French: Barrage de Bissorte) is a gravity dam in the Maurienne Valley, in Savoie, France, about 7 km (4.3 mi) east of Valmeinier. It was built from 1930 to 1935 to supply a hydroelectric plant capable of generating 75 megawatts (MW) of power.
The complex was reconfigured from 1980 to 1986 in order to add a 750 MW pumped-storage power plant known as Super-Bissorte, the third most powerful in France after Grand'Maison and Montézic.
