Outdoor Pond --- what to do with my KOI???

[Perodogo]

Thanks for all the replies. It is a bit of a dilemma and I've been on either side many times. I had originally intended not to stock my pond with livestock since I knew I'd face this problem, but being a fish hobbyist for many years, I just couldn't resist. You see, my pond is a bit of an after thought --- I really just wanted to circulate the water from our lake to my waterfall/stream but the control board declined my application--- so we had to create a pond as a collecting area for the stream. But now that I have several KOI's in there, I'm really enjoying them.

I have a coworker who has a small pond (approx. 300 Gal) and a lot shallower (18" deep) and he successfully kept his 4 KOI's outdoors last winter. I believe he used the same heater Steve was talking about, so I think I'll try that. I've also thought about keeping them in my garage, but I think my wife will divorce me first before that happens --- no room there either.

Cheers
