During the winter months, you’ll most often find big smallmouth on humps, ridges and ledges out close to the river channel. In some areas, the smallmouth may relate more to creeks than to the main river, depending on the history of the lake. At this time of the year, expect to catch the smallmouth in 18 to 20 feet of water, but always consider the clarity and the temperature of the water. A small, 1/4-ounce, black-and-blue or brown jig with a small pork trailer behind is productive for wintertime smallmouth.
