Hi Nasa,

Water forms layers when it is cold. The bottom of the pond can be several
degrees warmer than the top. Someone here once measured the temps with a
thermometer.

The still water is also easier on the fish, they don't have to work against a
current.

I'd go with the 55 degree temperature to stop feeding. That way you won't be
caught by a sudden down turn of the temps.
Go with the temperature at the top of the pond, just because it is easier.

Bonus question: a) I know water flow effects water tempature -- could someone
explain how?

Darn, don't get to go for the bonus points!
