A postcard from Serre-Ponçon Lake, (The 3L and Céline)

Lake Serre-Poncon (Lac de Serre-Ponçon) is a lake in southeast France; it is one of the largest artificial lakes in western Europe. The lake gathers the waters of the Durance and the Ubaye rivers, flowing down through the Hautes-Alpes and the Alpes du Sud to the Rhône River. The waters are dammed by the Barrage de Serre-Ponçon, a 123 m high earth core dam. As well as water control, sixteen hydroelectric plants use the water and the lake provides irrigation to 1,500 km2 of land.
