Here is a non-winter picture from two years ago:
Here is now:
Here are some of the koi: The smaller ones are the babies from two years ago.
And here's the hole I fell through a few weeks ago, that pond deicer works great, especially when there is a snow cover. Temps here have been in the -10's F, that's -23 for you Canadians. Sad thing, I fell through again last night, happens every year. At least its only a leg that gets wet. I need to check the light bulbs and check on fish. Last winter I had to pull half a dozen koi out, as they were sick. Saved all but one. Last thing I want is a dead fish killing off all the others. I don't remember what I have for bulbs in the deicer, I believe its two 40 watt and one 60 watt bulb. I'd check, but I'd end up falling through again!
