It is not often that Niagara Falls freezes in its entirety. Well, it has this year.
Here are a couple of shots of the currently frozen Niagara Falls.

Cant be frozen right through surely or the water would back up behind it wouldn't it.:uhoh:

Good point, normally, but the flow of the water over the falls can be governed. Which is done anyway at various times of the year. The water going over the falls right now is but a trickle, comparatively speaking of course.

There were floods due to water backed up behind ice dams just after the last ice age that almost removed two States from the face of the map. :uhoh:

I can't say anything about the frozen falls.

But the General must have a heck of a wide PC monitor. I had to scroll twice to see all of the 1st photo... ;)

I didn't know that, Tony. But now that I do I'm hopeful that if the same thing were to occur now, one of the States taken out would be Connecticut. :ok:

Niagara is one of the world's larger run-of-river power plants so a good portion of the water passes through the turbines rather than over the falls. If one closed all the turbine gates however...

After an excellent landing etc...

Tut tut Mr Rock,you should know more of your lands geology,500 cubic miles of water held up behind a ice dam and the dam let go,possibly the greatest flood event the world has ever known.

Wow, Tony. I did not know that. Makes for interesting, albeit horrific, reading. Thanks for the link. :ok:

That's okay, Tony D. has been referring to me as Mr. Rock for eons. I do prefer Sgt. Rock but Mr. will also do!

Tony - ah, in-joke. I shall wag a finger at myself in the mirror then! :O

I thought the Zanclean flood, which refilled the Med, was the biggest. It's happened a few times, IIRC.

This Sgt Rock?

The Three Gorges Dam has got a 175 m head. If that goes it will take out about 12,000,000 people.

Can't speak to the falls Sgt. Rock but our Georgian Bay is nowt but a sheet of ice to the horizon.
Actually a good thing for us as it reduces the lake effect snow streamers that can dump lashings of the white stuff on us in very short order.

It actually comes under the heading Climate Change

For the majority of its life the earth has been bereft of ice cover at all.

There was a time however when it froze solid from pole to equator North and South,there is some puzzlement as to why and how exactly it managed to unfroze itself. :uhoh:

SUVs, tons of them back then, no people, just millions of SUVs sitting around idling.

A lot of folks don't know that. :p

If it happened (that's where the puzzlement is), CO2 and Methane from volcanos would provide sufficient greenhouses gases to unfreeze the equator, then biology takes over - takes about 25 million years-ish. Goggle "Snowball Earth"

I think you will find the water is still flowing in those pictures.

Which of the Falls are frozen over, the American or the Canadian?

the one that created the English Channel

One of the greatest natural benefits England has enjoyed. Mind you it could usefully have been a bit wider: I rarely have time to finish my second bottle of Eurostar wine.....

Not quite as published ...... for example, the picture the OP used seemingly dates from 2007.

Oh Mr RGB, have you been economical with the actualité?

Please tell us that it's not so!

As even Lake Ontario is a product of the precipitation across the canadian landmass, the amount of water at the falls must be at a low during winter - as well as the highest volume of water comes with the thawing snow in spring and early summer.
The colder the season, the less water will run. And isn't it rather cold up north at the time?

The photos I posted were from a Reuters web site which claimed they were of the current, and frozen, Niagara Falls. I didn't check the dates on the published photos from that web site because I'm not quite that anal.
