"Ever" is a very long time, and eventually it probably will. However, it's not going to be anytime soon. Niagara falls is on the Niagara river, which carries water from lakes Superior, Huron, Michigan, and Erie to Lake Ontario. All of these lakes get filled from rivers and springs and rains just about as fast as they drain.
Niagara Falls uses hydroelectric power, (falling water to run electric turbines), and Yes, hydroelectric power, including Niagara Falls is a Renewal source of energy.
Both Niagra Falls and Yosemite Falls are waterfalls. That is probably as similar as they get. While Niagra flows all year, Yosemite Falls may run out of water in the summer. Niagra Falls is also wider than Yosemite Falls.
On the night of March 29, 1848, both sides of Niagara Falls inexplicably ran dry: Apparently an ice jam had formed on Lake Erie, which blocked the water that normally flowed along the Niagara River and over the falls. This "drought" lasted for 30 hours, until the weather and the winds "uncorked" the ice.(For more information - and some photos too - click on the Related link.)
Run off is when water run off our falls of hill ,moantins ,rocks
It does not run backwards! I should know since I've lived here for upwards of 49 years.The comment about Niagara Falls running backwards was made by Oscar Wilde, who said, "It would be much more interesting if the Falls ran backwards."But, just because Oscar Wilde said it, doesn't make it so!
all renewable energy resources (water falls, solar, wind, ...)a recource that winll not run out is wind water and elementsWind.
Grove Run and Rock Run join to form Linn Runn, which has a waterfall called Adams Falls.
The water evaporates, the vapor rises, goes in to the clouds , and falls again as rain or snow.

Water is never going to run out,, water itself will never run out, clean water or fresh water might run out but that's only a MIGHT, we can always come up with a way to clean salty water
The water runs off mountains and other things causing run offs
