It's a Jack-the-Ripper kind of night. The sky is dark, the air thick and damp, the moon just a sliver dancing between flashing black thunderheads. In the glare of our lantern, the eyes of my friend Jimmy Harris reflect the maelstrom of river below us. We sit high above the water on the thick oak planks of a country bridge, our feet dangling from the edge as we fish.

Jimmy's knife glints as he decapitates a small fish. The head sails into the weeds; the tail is impaled on a thick hook. Jimmy casts the bait toward a nearby riprap bank of the swollen river, and before the bait sinks to the bottom, his rod is yanked downward, and then straightens. Jimmy lifts the rod and waits. The line twitches; then he drops the tip and strikes. "It's big," Jimmy grunts.

He pumps the pole up and down, cranking in line. Out in the river, a sizeable fish thrashes on the dark surface, then dives again. More line peels from Jimmy's reel. It seems an eternity before he brings the fish alongside the bridge. When he does, I lift the lantern high, and we have our first look at the adversary. Churning the water below is a sleek fish 2 feet long, with a sharply forked tail and beady eyes. Its only adornments are a muzzle of long whiskers and spines on its back and sides.

Jimmy moves to the riverbank and drags 12 pounds of catfish up on the rocks. "How's that for a channel cat?" he beams. "That's the biggest I've caught. I'll bet there are some of his hungry kinfolk swimming around out there, too. The river's right tonight."

Rivers are among the best places to catch channel cats, a fact borne out by Jimmy and me that night. In fact, channel cats derived their name from their habit of hanging out around river channels. Catching them in these environs isn't difficult if you know some good strategies for fishing moving water. Here are three to make it so.

WINGING IT
Wing dikes, also called wing dams, are among the best big-river hotspots for channel cats. These long, narrow rock structures direct current into the main channel to lessen shoreline erosion. They are most numerous in hydropower and navigation dam tailwaters but may be scattered along the entire length of a large river.

Wing dikes fulfill their intended functions by diverting current. They usually lie perpendicular to shore, and when moving water strikes them, the water swirls back on itself. The force of the current then moves outward, toward the middle of the river. The water velocity slows, allowing suspended sediments to fall and accumulate on the river bottom.

Inactive channel cats typically stay on a wing dike's downstream side, lying on bottom, usually not far from shore, where current is minimal. Most feeding cats, especially the more numerous small cats, hold near the river's bottom on a wing dam's upstream side. The reason for this is three-fold. First, hydraulic action here creates a "tube" of reduced current near bottom that runs the length of the dam. Hungry cats can feed here without using excess energy. Also, this is a zone of abundant food -- crayfish and mussels in the rocks; shad, herring and other baitfish holding in the slower cylinder of water. Additionally, when the river's high and the wing dams are submerged, channel cats can feed on addled or injured forage.

There is another lesson, however, perhaps even more important: Trophy channel cats are best targeted around the eddies, or vortices of water, near the ends of wing dams. It would seem that bait tossed to the edge of an eddy would swirl round and round. But when done properly, the bait will sink quickly to the bottom and remain stationary. Reposition your rig if necessary to achieve this end, and then prepare for the rod-jarring strike that will soon follow if a big channel cat is nearby. Often, big cats cruise slowly through a hole, waiting for something to arouse their taste buds before they rush in to strike. Allow the bait to sit up to 10 minutes, but if there's no bite by then, move and try another eddy.
