It contains about 18% of the world's freshwater supply, with water flowing into the Great Lakes from streams and rivers that empty into it.

Do they turn Niagara Falls off at night?
The simple answer is no. During the summer once the sun goes down, the water flowing over the Falls is reduced from the daylight flow of 100,000 cubic feet per second to 50,000 - allowing hydro plants on both sides of the border to draw more water for hydro generation.
Do fish go over Niagara Falls?
Fish bodies are streamlined and relatively light so a long fall into water isn't usually a problem. Niagara River expert, Wes Hill, estimates that 90 per cent of fish survive the drop over Niagara Falls.

What will Niagara Falls look like in 1,000 years?
The water flow would concentrate in this notch like the blade of a buzz saw, and cut upstream at maybe 15 feet a year. That could create a big change in the next 1,000 years. Horseshoe Falls would retreat far enough to steal the water flow from American Falls. There could be only one fall left.
