Mine was 47 this evening.
Patti, water temps are not a problem if they are still flowing. All goldfish and Koi can handle ANY cool water temps as long as the pond isn't completely frozen over. Once the water fall starts to freeze by that point most bacteria have stopped working so at that point you just want to keep the oxygen level up and a hole for gas exchange. Once you do disconnect the stream/waterfall if possible leave a pump running from the bottom of the pond pushing upward But not shooting above the pond surface. ( does this make sense?) This will move less oxygenated water up toward the surface to regain O2 levels, also this will help keep a hole in the ice if there is a light covering of ice on the pond. Biggest thing is DO NOT FEED at all once the temps have dropped. even if they climb for a day or two and the fish become active don't feed, let them feed from what's in the pond and the body fat they have stored throught the summer month's. Here that happens quite often and it's hard not to throw a few pieces of food in for them. believe me they won't starve and you'll start off next spring with a far more stable pond and less chance of a algae bloom in the spring if you'll let them do their own natural feeding from algae's, plant matter, and insects that are in the pond.I took my pond thermometer out yesterday, and it was 42F here in IL. Brr .... but I'm sure it got warmer as the day went on, since it was up to about 60 yesterday. This morning, 60 outside, very windy but warm. Fish stopped eating about a month ago, when the temps got down to below 55, just like all of you said! Quit feeding at that time. They pretty much stay at the bottom now.
Wondering if I'm making the water colder by keeping the waterfall going (when the outside temps are colder, that is, as right now it's probably warming the water), and if that is a problem for the fish. My figuring is the water is going to be pretty much the temp of the outside, maybe change quicker with the waterfall still running. I want to keep the waterfall and skimmer running until freeze is imminent, as they will both be very easy to disconnect, drain, or drop tubing into the pond. Is this an ok idea? Thanks!

Thanks, Larkin. Yes, when I unhook my submersible pump from the waterfall, my intention is to leave the pump in the pond, shooting straight up. I'm hoping it won't have too much pressure and won't go above the surface, but I will soon find out. I may not need that floating heater after all, but will keep it just in case. I have the pump in the shallower area of the pond (41" vs. 48") and up on a 6" thick stone (which is on extra padding and extra layer of rubber liner) so it should not be down in any muck that forms this winter. My first winter, so I'm trying to listen to as much advise as possible on the winterization process.
And, I was guilty of stopping feeding the koi, then the water warmed up past the 55 degrees so I fed them for another week or 2, but learned that was not a good thing, so have not fed them for about a month or maybe little less now. Will wait until temps are consistently above 55 next spring before starting to feed them again, too.
