The Lake of Sainte-Croix (French: Lac de Sainte-Croix, pronounced [lak də sɛ̃tkʁwa]) 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.
Its surface area is 22 km2 and max. depth 93 m.
The reservoir is fed by the Verdon river, at the outlet of the Verdon Gorge. It holds a maximum of 761 million cubic metres of water. The dam, which generates 142 million kWh of electricity per year, is 94 metres high, 7.5 metres thick at its base and 3 metres thick at its crest.
