Waterfall Freezing

Moving water certainly DOES freeze, that is how clear ice for ice scupltures is made. All parts of a waterfall can freeze, it depends on the volume of water, height, width and what it is flowing over. If its coming over a rock face then the water touching the rock will freeze first and stick on. Sometimes they freeze from the edges, bottom or top first. There are a lot of factors involved. Some can freeze solid. Check out info about Ice Climbing around Quebec City.
In most places in Canada, falls that freeze are usually frozen between January and March. Generally when the absolute temperature is -20oC or less but it can be warmer for them to STAY frozen.
Wind Chill is ONLY felt by living things, it has no bearing on water.

they freeze 2 ways at the same time....
water at the bottom becomes ice and gets thicker and grows upward and at the top it does the same thing until they meet.
after they meet and have a solid sheet of ice from top down... the other water rusing by also freezes on the ice and eventually the fall is plugged with ice.
Once the plug happens the ice on the top... at the stream level gets thicker and thicker until the whole stream is ice.
Niagra falls froze in the late 1800's or early 1900's. It just has to be real cold for a long time.
Once the temp rises.... waterfalls will break that ice off pretty quick and dump it down to the bottom and it's back in business.

They freeze one droplet at a time...literally. When the droplets are suspended in the air, they are small enough to freeze instantly. Remember, not only is the air cold, but there is a strong breeze created by the waterfall itself as it crashes into the rocks below. So there's got to be a wind chill factor involved too, making them freeze even faster than normal.

Waterfalls freeze When the right time comes

Waterfalls don't really freeze silly willie ;3. Just the surface freezes. If you wanted to die by drowning if you smashed it the water would still be flowing under there. But it has to be SUPER cold first.

when the climate around it get too cold the water at the peek of the dropping point freezes then water trickles down the layer of frozen water it will freeze and then the cycle keeps coming and there you go! a frozen waterfall!

Moving water can not freeze. It's the rims that freeze, then the outside slowly freezes. If it looks totally frozen, the water inside is still moving.

The whole waterfall doesn't freeze it's just the outside water that does....the water inside the frozen mass is still flowing.

Heavy waterfalls don't freeze because of the steady water flow. It would have to be severe below temperatures for that to happen.
