The Robert-Bourassa Reservoir (in French: "Réservoir Robert-Bourassa") is a man-made lake in northern Quebec, Canada. It was created as part of the James Bay Project and provides the needed water for the Robert-Bourassa and La Grande-2-A generating stations. It has a surface area of 2,835 km² (1,095 mile²), has an estimated volume of 61.7 km³ (14.8 mile³), and a surface elevation between 168 m (551 ft) and 175 m (574 ft) [ [http://www.hydroquebec.com/visit/virtual_visit/reservoir.html Hydro-Québec - Robert-Bourassa Reservoir] ] .

The reservoir is formed behind the Robert-Bourassa Dam that was built across a valley of the La Grande River. This dam was constructed from 1974 to 1978, is 550 m (1,800 ft) wide at its base, and has 23 million m³ (30 million yd³) of fill [ [http://www.hydroquebec.com/visit/virtual_visit/barrage.html Hydro-Québec - Robert-Bourassa Dam] ] . There are another 31 smaller dikes keeping the water inside the reservoir.
