Ditto on Stacey

Water is never dry, check the videos, check the amount of the water and I hope you will understand.

It never dries up. In the winter some of the water gets frozen.

Niagara falls never dry!

It's Niagara Falls it does not evaporate or change water level drastically.

No. There is a lot of water. It does not evaporate in the summer.
