Today is the anniversary of my PB from a pond (4lbs, 2oz). I'm from AZ where the weather & water don't get nearly as cold as most places, but I think the method I used could produce fish anywhere this time of year if the conditions are right.
I threw a Strike King Bitsy Bug jig, 3/16oz in watermelon, with a 3" watermelon single tail grub, about 2 yards off the shoreline, as I would fish a Senko. Only caught that one fish in about two hours of fishing, but I'll never forget that AZ winter day. Downsize, slow down, and look for the fish where you expect them to be cruising along looking for an easy, slow meal. GL!
