We don't typically experience extended periods of ice here. 2-3 weeks in a bad winter. My pond has a high volume for its size thanks to the depth,
but I do intend to set a diffuser up shallow this winter, and run it 24/7 when air temps are below freezing, just to be on the safe side.

The bluegill wars will continue this fall, until the water cools to the point that I can no longer catch/trap/net them.
The HSB are so stinking expensive that I can't bring myself to start harvest of them until they size up a bit.
I want one more spawn out of the YP before I begin to harvest them.
