I've got my winter water supply finished, a submersible pump in a tub dug into the stream is supplying 12GPM to the pond.
The insulated water line runs 120ft. from the stream up to the pond and should be able to keep the pond level up and provide oxygenated water to the trout, that's if it doesn't freeze.
The pond has 1/2 inch of ice now and the forecast is for 4 to 8 inches of snow tomorrow.
The aerator runs 24-7 now and has a decent opening in the ice and I also have a submersible pump in 4ft of water keeping an open area near the dock.
The 2 inch gravity feed pipe is on the right, it puts out 60gpm and runs 300ft. up above the waterfall, but I will shut it down soon so it doesn't freeze solid. The insulated pump line is on the left.
