How to Catch Catfish in Rivers and Lakes

Catfish are one of the most rewarding species to target in freshwater. They fight hard, grow big, and they are not nearly as picky as trout or bass when it comes to bait and presentation. Whether you are fishing a slow-moving river or a deep reservoir, catfish are usually willing to bite if you put the right offering in the right spot.

That said, there is a big difference between sitting on a bank and hoping for a bite versus consistently finding and catching catfish.

The anglers who load the cooler understand where catfish live, what they eat, and how to adjust between rivers and lakes.

Know Your Species

The three main catfish species in North America each behave differently. Channel catfish are the most common and the most forgiving to target. They eat a wide range of baits, roam frequently, and can be found in almost every body of warm water in the country.

They typically run 2 to 10 pounds, though fish over 20 are caught regularly.

Blue catfish are the bruisers. They grow over 100 pounds in some river systems and tend to school up in deeper water. Blues are predatory and respond well to fresh-cut bait, especially shad and skipjack herring.

Flathead catfish are the loners. They prefer live bait, hide in heavy cover during the day, and feed aggressively at night.

Catching big flatheads requires patience and a willingness to fish after dark in sketchy-looking spots with submerged timber.

River Catfishing Tactics

Rivers concentrate catfish in predictable locations. Current is the key variable. Catfish do not want to fight current all day, so they position themselves in areas where the flow breaks or slows down. Wing dams, bridge pilings, outside bends with deep holes, and the downstream side of large rocks are all prime spots.

The junction where a tributary enters the main river is one of the best locations you can fish.

These spots collect baitfish, crawfish, and debris, creating a natural feeding station. After rain events, tributary mouths become even more productive because runoff pushes food into the main channel.

For rigging in rivers, a slip sinker rig is the standard. Thread an egg sinker onto your main line, tie on a barrel swivel, then run 18 to 24 inches of leader to a circle hook. The slip design lets catfish pick up the bait and move without feeling resistance, which leads to better hookups.

Use enough weight to hold bottom without the current dragging your rig downstream. In moderate flow, 2 to 3 ounces usually does the job.

In heavy current, you might need a no-roll sinker up to 6 ounces.

Lake Catfishing Tactics

Lakes spread catfish out more than rivers, so finding them takes a slightly different approach. In spring and early summer, catfish move shallow to spawn. They use riprap banks, clay flats, and shoreline cover. This is the easiest time to catch them from the bank.

During summer, channel catfish in lakes often suspend over deep flats and follow schools of shad.

Using sonar to locate baitfish schools and then anchoring above them is extremely effective. Drop your bait to the depth where you are marking fish and wait.

Blue catfish in lakes tend to hold on main-lake points, humps, and channel ledges. Structure-related fishing with cut bait on the bottom is the standard approach. Drift fishing also works well on large flats where blues are scattered.

Night fishing on lakes is productive year-round.

Catfish move shallower after dark, often cruising flats in water as shallow as 3 feet. A simple setup of a lantern on the bank, a rod holder, and fresh bait will catch fish consistently.

Best Baits

For channel catfish, the list of effective baits is long. Chicken liver, punch bait, dip bait, nightcrawlers, shrimp, and cut shad all work. Prepared baits like Sonny's or CJ's produce well in warm water when the smell disperses quickly.

For blue catfish, fresh-cut shad is the top bait in most river systems.

Fresh is critical. Catfish can tell the difference between bait that was caught that morning and bait that has been sitting in a freezer for three months. Skipjack herring is another excellent option where available.

For flathead catfish, live bait is almost mandatory for consistent results. Live bluegill, green sunfish, and small bullheads are the top choices. Hook them through the back behind the dorsal fin to keep them active and swimming.

Gear Basics

You do not need expensive tackle to catch catfish. A medium-heavy spinning rod in the 7-foot range paired with a 4000-size reel handles most channel cat situations. Spool it with 20-pound monofilament or 30-pound braided line.

For big blues and flatheads, step up to a heavy casting rod with a baitcasting reel. Abu Garcia 6500 series reels are a catfish standard for good reason. They are tough, hold plenty of heavy line, and have a smooth drag system that handles long runs.

Circle hooks in sizes 5/0 to 8/0 are the best all-around choice. They hook fish in the corner of the mouth almost every time, which makes unhooking easy and keeps the fish in better shape for release.

Time of Year Matters

Spring is the prespawn feed-up period and one of the best times to target catfish in both rivers and lakes. Water temperatures in the 55 to 70 degree range trigger heavy feeding. Summer is prime time for night fishing and targeting fish in deep, cool water during the day. Fall brings another feeding binge as catfish bulk up before winter. Winter fishing is slower but still productive on warm afternoons, especially in rivers where current keeps catfish active year-round.

Putting It Together

Catfish reward anglers who pay attention to location and bait freshness. Find the spots where current breaks or structure concentrates food, use bait that matches what the local catfish are already eating, and fish with enough patience to let the bite develop. Whether you are sitting on a river bank at midnight or anchored over a lake hump at noon, catfish are almost always willing to cooperate if you give them the right opportunity.
