Oh yes. The water was still moving. That was the first thing I checked. You really couldn't see it in these pictures, but it was still coming down the waterfall and out the return. It was only about the top inch that was frozen. They were all down at the bottom, chilllin'. They have an odd tendency to orient themselves in the same direction and just stay put.

I'm not sure about what happens when it freezes over completely on the top surface. Usually there is a bubbler or waterfall for oxygen.
Izzy did I get that right?
Close, Sharon. Ponds need to be at least a foot below the average depth the ground freezes in the winter. Here that's just like 2 feet deep, but up in the great white north, it can be as deep as 5 feet. My pond is 3 feet deep. I wanted to add that extra foot in there for added measure. And for things like this. If I lived in a place where freezing over the pond was common I would add a bubbler or a water trough heater in the middle to keep the ice open, but for now, the waterfall still moving was enough.
All snow is gone now, tho. Such is the ephemeral fate of snow in the south.
