Looking down the Niagara River South of Lewiston and North of Niagara Falls, New York, you can see the vast Hydroelectric plant off of the Niagara River. This plant dumps clean water back into the Niagara River after winding up the electric generating turbines in the plant from water tapped off of the river upriver. There is a large and long dug canal that goes from upriver to the back side of this plant. The left side of the bank here is Canada and they also have an hydroelectric plant around the bend. The American side plant has free tours and a museum and movies so it is well worth the stop to see it.
