Ok, got it.
Just back from the pond. I’ve actually got water coming out the overflow pipe. Still frozen over. This is the longest I’ve ever had it iced over. No snow on the ice, so I think the fish are ok. I hope so anyway. Going to be 18 here tonight and in the 20s at night for the next two weeks. I don’t think the ice is going anywhere.

9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
