When fishing some of the colder ponds down east I have always had good luck with a combination bait trolled or moved gently along through any markings on the graph. If I am not marking fish I will go closer to the banks and fish as close as I can without getting hung up... in about 3-7 ft of water.

My favorite combination bait for small to medium sized ponds is a 1/16oz Zeta Jig in a chartreuse body and head color with red flakes. Tipped with a very small minnow. Fished about 18" under a swivel and 1/8 oz. bullet weight. Tight lined on my 12' B&M with 6lb. florocarbon. At whatever water depth that you are marking fish, or anything that looks fishy.

Good luck and let us see some pics when you get the big one! Fishengineer
