What to fish at Lacey-Keosauqua State Park
Lacey-Keosauqua State Park sits where the Des Moines River cuts through southeastern Iowa, and the river is the main draw for anglers. You will find catfish — channel and flathead — as the most reliable catch, especially from spring through fall. Walleye and sauger show up in decent numbers, particularly in early morning and evening. The park also holds smallmouth bass, largemouth bass, and carp, though these are secondary to the catfish and walleye fishery.
The Des Moines River here is a working river with current and structure. It is not a clear-water lake; the water is often stained or turbid, which actually favors catfish and walleye over sight-feeding species. The park's location near the confluence of the Des Moines and Skunk Rivers adds complexity to the water — you get tidal influence from the Mississippi system downstream, and water levels can swing with dam releases upstream.
Key Takeaways
- Channel catfish and flathead catfish are the primary target species, with the best action from April through October.
- Walleye fishing is solid in spring and fall, and early morning or dusk produces better than midday.
- The park has boat ramps and bank access; a boat gives you far more water to cover than shore fishing alone.
- Water levels and current vary with dam releases upstream, so check conditions before you go and adjust your tactics accordingly.
- The park sits in Van Buren County; Iowa fishing licenses are required, and catfish have no minimum size but do have daily limits.
Seasons and what to expect month by month
Spring (April through May) brings warming water and active catfish. Channel cats move into shallower areas to feed, and live bait — shiners, shad, or crawdads — works well. Walleye also turn on in spring, especially in the first hour after sunrise. Water levels are often higher in spring due to snowmelt and rain, so the river can be muddy and current-heavy.
Summer (June through August) is peak catfish season. Flathead catfish become more aggressive as water warms, and they prefer live baitfish over cut bait. Catfish fishing is often better at night or in low-light conditions. Walleye bite slows in the heat of summer, though you can still catch them in deeper holes and along current breaks early and late in the day.
Fall (September through October) brings another strong bite. Water cools, walleye become active again, and catfish feed heavily in preparation for winter. This is often considered the best overall season at Lacey-Keosauqua because both catfish and walleye are willing and the weather is more comfortable for long days on the water.
Winter (November through March) slows the action significantly. Catfish are still present but less aggressive, and most anglers shift focus to other waters. The river can be dangerous in winter due to ice and cold water, so check conditions carefully before launching.
Access, boat ramps, and where to fish
The park has two main boat ramps: one at the main park area near the town of Lacey and another downstream near Keosauqua. Both are public and free to use with a valid Iowa fishing license. The ramps are concrete and generally well-maintained, though water level changes can affect launch difficulty — call ahead during high or low water periods to confirm conditions.
Bank fishing is possible at several spots around the park, particularly near the main picnic area and along the road that runs parallel to the river. The Des Moines River here is wide and has good current, so a boat lets you reach deeper holes, current breaks, and structure that shore anglers cannot reach. If you do not have a boat, focus on the deeper pools near the ramps and the outside bends of the river where current has carved deeper channels.
The park also has camping facilities — both tent and RV sites — so you can stay overnight and fish early morning and evening when the bite is strongest. Reservations are handled through the Iowa Department of Natural Resources website.
Tackle, bait, and tactics for catfish and walleye
For catfish, use medium to heavy spinning or baitcasting gear. Channel cats respond to cut bait (shad, herring, or chicken liver), live bait (shiners or crawdads), and stink baits. Flathead catfish are more aggressive and prefer live baitfish — 4 to 8 inches — fished on the bottom or near structure. Use 15 to 30-pound monofilament or braided line; the river has snags and the current is strong. Fish the deeper holes, outside bends, and areas with fallen trees or rock.
For walleye, use lighter tackle — 6 to 10-pound monofilament on a spinning rod. Live shiners or crawdads work well, as do small crankbaits and jigs. Fish early morning and evening, and focus on current breaks, deeper pools, and the edges of the main channel. Walleye in this river are often active in 8 to 15 feet of water.
The Des Moines River's stained water means you can fish throughout the day, but low-light periods — dawn, dusk, and overcast days — are consistently more productive. Night fishing for catfish is popular and often the best option in summer.
Regulations and licensing
You must have a valid Iowa fishing license to fish at Lacey-Keosauqua. Licenses are sold online through the Iowa Department of Natural Resources website, at the park office, and at most sporting goods stores in the region. A one-day license is available if you are just passing through.
Channel catfish have no minimum size and a daily limit of 10 per person. Flathead catfish also have no minimum size but a limit of 5 per person. Walleye have a 15-inch minimum and a limit of 6 per person. Sauger have a 12-inch minimum and a limit of 6 per person (combined with walleye). Bass have a 12-inch minimum and a limit of 5 per person (combined species). Check the current Iowa fishing guide before you go, as regulations can change year to year.
The park is open year-round, but facilities and services vary by season. The boat ramps are accessible in winter, though ice and cold water create hazards. Camping is available spring through fall, with limited winter facilities.
When water levels and dam releases affect your day
The Des Moines River is controlled by dams upstream, and water releases can raise or lower the river level significantly in a short time. High water makes the current stronger and the water murkier, which can actually improve catfish fishing but makes boat handling more difficult. Low water concentrates fish in deeper holes but also exposes snags and makes navigation trickier.
Before you launch, check the U.S. Army Corps of Engineers website for dam release schedules, or call the park office. Water level changes affect where fish hold and how they feed, so adjust your location and tactics accordingly. High water often pushes fish into slack water near the banks; low water concentrates them in the main channel and deeper pools.
Nearby towns and services
Keosauqua, just south of the park, has gas, food, and lodging. Lacey is smaller but has a few services. The nearest larger town is Ottumwa, about 30 miles north, which has more restaurant and hotel options. The park itself has a small office and picnic facilities, but no on-site tackle shop, so bring what you need or stop in Keosauqua before you arrive.
Cell service is spotty in parts of the park, so do not rely on your phone for navigation or emergency contact. Bring a map and let someone know where you are fishing.
Frequently Asked Questions
What is the best time of day to fish at Lacey-Keosauqua?
Early morning (one hour before sunrise to two hours after) and evening (two hours before sunset to dark) are most productive for walleye and bass. Catfish bite throughout the day but are often more aggressive at night, especially in summer. Overcast days can produce good fishing all day.
Do I need a boat to fish here?
No, but a boat gives you access to much more water and deeper structure. Bank fishing is possible near the ramps and picnic areas, and you can catch catfish from shore, but you will cover less water and miss some of the best holes.
Can I keep flathead catfish, and are they good to eat?
Yes, flathead catfish are legal to keep within the daily limit. They are edible and some anglers prefer them to channel cats, though they are more aggressive and harder to handle. Channel catfish are the more traditional table fish in Iowa.
What should I do if the water level is very high or very low?
High water makes the current stronger and the bite often better for catfish, but boat handling is more difficult. Low water concentrates fish in deeper pools but exposes snags. Call the park office or check the Corps of Engineers website before launching to plan your approach.
Is there a tackle shop at the park?
No. Bring your own tackle or stop in Keosauqua before you arrive. The park office can point you to the nearest shop if you need supplies.
