At various times the lower Niagara River Whirlpool is a whirlpool in name only. When the river is flowing at its normal volume, water rushes into the pool and is carried past the river outlet on the right. It circulates counter-clockwise, creating a traditional whirlpool. When the volume is low (that’s when more water is being diverted above the falls for power purposes) the Whirlpool shows no circular motion at all and becomes a “Whirlpool” in name only.
Look carefully and you can see the red Whirlpool Aero Car above the whirlpool in the centre of this photograph.
My brother Greg, who was a helicopter pilot at the time, took me into the sky in the early 80’s to capture this photograph.
