hoo haa ... scroll down to winter pond. http://weloveteaching.com/mypond/mypond.htm
I drop in a tank heater (titanium, aquatic ecosystems).
I cover the pond with plastic. the temp is 50 or better all but one month. without
the heater and plastic the temp goes down for 6 months.
with heater and plastic I feed the fish nearly all winter but only a little bit and
not every day.
This year I am putting a sort of greenhouse around the whole pond area (if I ever get
to it!) so I can actually sit right next to the pond and watch the fish and exclude
the snow. Ingrid

Our pond is at a house we have for sale near Oregon City. The realtor does
the minor maintenance between our visits. We now live in central Oregon and
I'm debating with myself the pros and cons of having a pond here. Our
winters can drop to -20°F and I'm uncertain how a pond with fish would do.
I'd like to hear from anyone that has a pond in that kind of climate as to
how they prepare their pond for the winter and what they do as far as
maintenance then the weather is sub zero.
