The Lewis and Clark Lake Catfish Tournament runs each summer on the Nebraska-South Dakota border
The Lewis and Clark Lake Catfish Tournament is an annual summer event held on Lewis and Clark Lake, the reservoir that forms the border between Nebraska and South Dakota along the Missouri River. The tournament draws anglers who fish for channel catfish, flathead catfish, and blue catfish — the three species that dominate the lake. The event typically takes place in July, though the exact dates shift year to year, so checking with the organizers or the Nebraska Game and Parks Commission is necessary to confirm the current year's schedule.
The tournament is open to both experienced catfish anglers and people fishing for catfish for the first time. Most tournaments of this type charge an entry fee per boat or per angler, with prize money distributed to the heaviest fish, the most fish caught, or both categories depending on how the tournament is structured that year. The lake itself is large — about 25 miles long — so knowing where catfish hold and what time of day they bite matters more than luck.
Key Takeaways
- Lewis and Clark Lake's catfish tournament happens in July each year, with exact dates available through Nebraska Game and Parks Commission or local marina contacts.
- Channel catfish, flathead catfish, and blue catfish all live in the lake, and tournament rules specify which species count and any size or weight minimums.
- Entry fees and prize structures vary by year, so contact the tournament organizer directly to learn what it costs to enter and how winnings are divided.
- Night fishing and early morning are peak times for catfish on Lewis and Clark Lake, and live bait or cut bait produces more consistently than other methods.
Where catfish hold on Lewis and Clark Lake
Lewis and Clark Lake has deep channels, shallow flats, and current breaks where the Missouri River flows into the reservoir. Catfish — especially channel catfish and blues — move between deep water during the day and shallower feeding areas at night. The old river channel that runs through the middle of the lake holds catfish year-round, but in summer they often move to shallower structure: fallen trees, rock piles, and the edges of weed beds where baitfish gather.
The upper end of the lake, closer to the dam, tends to have stronger current and attracts catfish that prefer moving water. The lower end has more slack water and is often better for anglers who want to anchor and wait. Talking to the marina staff at Yankton or other launch points before the tournament gives you real information about where fish have been caught recently — this matters more than general advice about catfish habitat.
Tackle and bait that work on Lewis and Clark Lake
Catfish on Lewis and Clark Lake respond to live bait and cut bait more reliably than to other presentations. Live shiners, shad, or bluegill work well for flathead catfish, which hunt live prey. Channel catfish and blue catfish eat cut bait — chunks of shad, herring, or skipjack — and also respond to stink baits and dip baits, though cut bait is usually more effective in a tournament setting where you want consistent results.
Rod and reel setup matters less than people think, but a medium-heavy rod with a sensitive tip helps you feel bites in deep water. Catfish do not require expensive equipment; a basic conventional reel or a sturdy spinning setup will land fish. The real advantage comes from using enough weight to keep your bait on the bottom or in the strike zone, and from checking your lines frequently so you know when a fish is there. Many tournament anglers fish multiple rods (check the tournament rules for the limit) so they can cover more water and more bait options at once.
Timing and seasons for the tournament
The tournament happens in July, when water temperatures are warm and catfish are actively feeding. July is not the absolute peak for catfish on Lewis and Clark Lake — June and early September often produce larger fish — but the tournament date is set for summer convenience and accessibility. Water temperature in July typically ranges from 75 to 80 degrees Fahrenheit, which keeps catfish moving and feeding through the night.
Night fishing is almost always more productive than daytime fishing for catfish, and most tournaments allow fishing from sunset to sunrise or run an overnight format. If you are new to night fishing on a large lake, practice your boat handling and navigation before the tournament. Bring a good headlamp, know where your launch point is, and file a float plan with someone on shore so they know where you are fishing.
Rules and regulations specific to Lewis and Clark Lake
Nebraska and South Dakota share management of Lewis and Clark Lake, and the regulations differ slightly between the two states. If you are fishing from the Nebraska side, Nebraska Game and Parks Commission rules apply; if you are on the South Dakota side, South Dakota Game, Fish and Parks rules apply. Both states require a fishing license, and both have daily catch limits and size restrictions on catfish. The specific limits change periodically, so check the current regulations before the tournament.
The tournament itself will have its own rules — which species count, whether there is a minimum size, how fish are weighed, and whether you can cull (release smaller fish and replace them with larger ones). Get a copy of the tournament rules when you register, because violating them can result in disqualification even if you follow state law. Most tournaments require that all fish be alive at weigh-in, which means keeping them in a livewell or a net during the day.
How to register and find current tournament information
Registration for the Lewis and Clark Lake Catfish Tournament usually opens in late spring or early June. You can register through the Nebraska Game and Parks Commission website, through local marinas on the lake, or through the tournament organizer directly. Some tournaments fill up quickly, especially if prize money is substantial, so registering early is wise.
The most reliable source for current dates, entry fees, and rules is the Nebraska Game and Parks Commission's events page or a call to their regional office. Local marinas — including those in Yankton, South Dakota, and on the Nebraska side — also post tournament information and can answer questions about current fishing conditions. Facebook groups dedicated to Lewis and Clark Lake fishing often have tournament announcements and anglers sharing recent catch reports.
Preparing your boat and safety gear
Lewis and Clark Lake is large and can develop rough water quickly, especially in summer afternoons when wind picks up. Before the tournament, make sure your boat is in good working order: check the engine, fuel system, battery, and navigation lights. Bring a working GPS or know how to navigate by landmarks. A life jacket for each person on the boat is required by law and by common sense.
Bring more water and snacks than you think you will need, a first aid kit, a flashlight and headlamp with extra batteries, and a way to communicate if something goes wrong — a cell phone or a marine radio. If you are fishing at night, make sure your running lights work and that other boats can see you. Tell someone on shore where you are fishing and when you expect to return.
Frequently Asked Questions
Do I need a fishing license to fish the tournament?
Yes. You need a valid Nebraska or South Dakota fishing license depending on which state's waters you are fishing. You can purchase a short-term license online or at a sporting goods store if you do not have one already. The tournament organizer will ask to see your license at registration.
What is the best bait for catfish on Lewis and Clark Lake?
Cut shad or herring works consistently for channel catfish and blue catfish. Live shiners or bluegill are better for flathead catfish. Stink baits and dip baits also work, but cut bait usually produces more fish in a tournament setting. Bring multiple bait options so you can adjust if one is not working.
Can I fish during the day or only at night?
Most tournaments allow daytime fishing, but catfish bite much more reliably at night on Lewis and Clark Lake. Many anglers fish through the night and rest during the day. Check the tournament rules for the exact fishing hours allowed.
How do I keep fish alive in my boat during the tournament?
A livewell with circulating water is the standard method. If your boat does not have a livewell, you can use a net or a mesh bag tied to the side of the boat in the water. Keep the water moving and check on your fish regularly so they do not become stressed.
What should I do if I am new to catfish fishing?
Fish the tournament with someone who has experience on Lewis and Clark Lake, or spend a day or two practicing before the event. Talk to marina staff about recent catches and where fish have been found. Start with cut bait and simple bottom-fishing techniques — catfish do not require complicated methods.
