A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation.
Reservoirs can be created in a number of ways, including contro ...
without any major water-level fluctuations (the
Laforge-2 generating station is the other). Thus, the amount of electricity generated by the station depends almost entirely on the water-flow of the river, which is largely controlled by upstream reservoirs and generating stations.
