When pond fishing got tough for me in the past, I usually would throw a Texas rigged, 6 or 8 inch Watermelon-Red Lizard. Slow move it across the bottom. Ponds cool down faster than deep water lakes. So, the fish seem to slow down, too. IMO Best to fish the afternoon, shallow where the sun has warmed the water up.
Found this interesting article:
"Bass fishing in winter months can be very tough. Like humans and all other animals bass do not like to move much in the winter and like to store up on food to avoid having to hunt as often. The key to catching bass in the winter is to use large baits and fish them very slow. Brush hogs tend to work well in the winter months when bass fishing. A large jig or chatterbair with a pork trailer will also do the trick. If a bass is going to have to move around a lot in the cold water the treat better be worth it. Think big! This time of the year is a perfect time to bust out those 12inch worms you bought at walmart for 10 cents.
When fishing for bass in the winter time use large baits like mentioned above, but also remember to fish very slow. Remember winter, bigger and slower - summer, smaller and faster. Also try and keep your baits warm, for example place them in your back pocket or in your coat. A warmer bait will work better in the cold waters"
