Pond/Waterfall Questions

The temperature that makes the most sense to me is 39 degrees, since water
is densest at 39 degrees and any water movement when the temperature is
below 39 would tend to mix the warmer water at the bottom with the colder
water at the top chilling the fish to below 39. The fish move to the bottom
to take advantage of the soil heat coming through the liner warming the
bottom layer of water. Cold water holds much more oxygen than warm water
and the fish use much less oxygen when cold and dormant than when warm and
swimming around.

"Turn off pumps, waterfalls and fountains for the winter"??

As a new guy I'm confused here, since I thought we kept the waterfalls
going
to provide oxygen for fishies in the winter.

If I *should* be turning off the waterfall, when does "winter" arrive?
When
the water crosses the 55 degree line???

Newguy lookin' for help...

Thanks!

You don't have to worry about cold
water going all yukky on you.

With fish most of us turn off pumps,
waterfalls and fountains for the winter.
