Despite the cold, there are plenty of places where the big ones can be caught. Typically, the big fish hunker down in deeper water this time of year, but will at times move into shallower water to feed, depending on the air pressure, temperature, and several other factors. Washington DC has the benefit of several warm-water discharges, which at times can be 15 degrees warmer than the rest of the river. Shad, the primary forage for big blues, are not very cold-tolerant, and so will congregate around these areas. Last trip out on 3 January found some good 30 pounders in deep water, but the 44# above was caught shallow, just ahead of a big front. Unlike channel catfish and flatheads, blue cats do feed actively over the winter; their metabolisms slow down, but smaller baits in the right place will get them to bite. As long as the river conditions are safe, it is a great time of year to bundle up and get out on the water!
