Niagara Falls

The peak flow over Horseshoe Falls was recorded at 6,370 m3/s (225,000 cu ft/s). The average annual flow rate is 2,400 m3/s (85,000 cu ft/s). Since the flow is a direct function of the Lake Erie water elevation, it typically peaks in late spring or early summer. During the summer months, at least 2,800 m3/s (99,000 cu ft/s) of water traverse the falls, some 90% of which goes over Horseshoe Falls, while the balance is diverted to hydroelectric facilities and then on to American Falls and Bridal Veil Falls. This is accomplished by employing a weir – the International Control Dam – with movable gates upstream from Horseshoe Falls.
