Encyclopedia
The Robert-Bourassa Reservoir (in French: Réservoir Robert-Bourassa) is a man-made lake in northern Quebec, Canada. It was created in the mid 1970s as part of the James Bay Project
and provides the needed water for the Robert-Bourassa
and La Grande-2-A generating station
s. It has a maximum surface area of 2835 square kilometres (1,094.6 sq mi), and a surface elevation between 168 metres (551.2 ft) and 175 metres (574.1 ft). The reservoir has an estimated volume of 61.7 cubic kilometres (14.8 cu mi), of which 19.4 cubic kilometres (4.7 cu mi) is available for hydro-electric power generation.
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. There are another 31 smaller dikes keeping the water inside the reservoir.
