After the partial diversion of the Rupert River
The outflow from the Rivière Eastmain was ± 600 m3/s. The natural inflows (i.e., the water from nearby mountains and rivers) to Opinaca reser voir is ± 300 m3/s. The total flow at the spillway of Sarcelle powerhouse was hence ± 900 m3/s.
New inflows from the Ruper t diversion are ± 450 m3/s, for a total flow of ± 1,350 m3/s to Sarcelle powerhouse.

= 100 m3
Year 2010 Due to unusual weather conditions (there was little precipitation and natural inflows were low), 2010 cannot be considered a reference year.
Did you know ... A trailer truck is the equivalent of 100 m3 of water.
