I just saw this.
In waters that shift as much as yours do, fish behave accordingly. In short that means that a) they are going to become lethargic when the water falls below sixty-or so, and b) they are going to seek the most stable water temps (called Thermoclines) available in the waters in which they live.
The first factor calls for live bait. One of my personal favorites - in subtropical lakes during the winter or lakes and ponds in the colder climes is big wiggly worms. It is a bait you can grow yourself with. Table scraps, plenty of coffee grinds, and a willingness to stir the dirt once in a while.. River fishing is somewhat different, so for now let's think lakes. Lakes are going to be more productive in colder states in the winter anyway, so that alone (lake fishing instead of rivers) will improve your odds. So the first thing to do is fish with big worms or with life shiners or other small fishies. Check regulations about what is legal and figure that everything that swims will be eaten by a winter sluggish fish if you put it on their heads. Think structure and fish where the fish are.
Thermoclines are based on feeds, among other things. If you can find where a spring feeds a lake, then you will find a deep spot, structure, and bass - both largemouths and smallmouths. Crappie, as well, stick around the spring feeds in the winter. The water temps remain constant, and at a certain int the temps stop falling.
I hope this helps, Max. Now do a video talking about what I just taught you and put it up :)
