Approximately 3160 tons of water flows over the Niagara falls every second. The amount of water at that force running over the Niagara Falls 24/7 is strong enough to do some serious damage throughout the years.
How do we preserve it? Does Niagara Falls get shut off at night? Long story short, the flow of water over Niagara Falls is reduced throughout the night to allow more water to be directed into the intakes for power generation.
This power supplies more than one-quarter of all the power used in New York state and Ontario, Canada!
JUST LISTEN TO THAT POWER!
