Lake of Sainte-Croix
Alpes-de-Haute-Provence, France
The Lake of Sainte-Croix (Lac de Sainte-Croix, pronounced [lak də sɛ̃tkʁwa], Occitan: Lac de Santa Croza) is a reservoir in Southern France that was formed by the construction, between 1971 and 1974 (when it was put into service), of a reinforced-concrete arch dam, the Sainte-Croix Dam. It marks the departmental border between Var to the southeast and Alpes-de-Haute-Provence to the northwest.
