What You'll Find at Eagle Slough

Eagle Slough Natural Area is a shallow, weedy backwater off the Ohio River just outside Evansville—the kind of place that looks small on a map but holds more fish than you'd expect. The slough runs roughly 2 miles and averages 4 to 8 feet deep, with dense stands of cattails, willows, and submerged timber that create ideal habitat for largemouth bass, bluegill, and channel catfish. The water is slow-moving and murky, which means the fish rely heavily on vibration and smell rather than sight.

Access is straightforward: there's a public boat ramp at the main parking area on Bussing Drive, and the slough is protected from river current, so even a small johnboat or canoe works well here. The area is managed by the Audubon Society and the Indiana Department of Natural Resources, which means it's kept relatively quiet—you won't find jet skis or heavy commercial traffic. That peace is part of what makes it worth the drive from downtown Evansville.

Key Takeaways

  • Eagle Slough is a shallow, weedy backwater ideal for largemouth bass and bluegill, with a public boat ramp on Bussing Drive.
  • The water is murky and slow-moving, so dark-colored lures and live bait work better than bright topwater presentations.
  • Spring and fall are peak seasons; summer heat pushes fish into deeper holes near timber, and winter access can be limited by ice.
  • A current Indiana fishing license is required, and the area has no-wake zones to protect nesting birds, especially in spring.
  • The slough is best fished early morning or late evening when light is low and fish move into shallower water to feed.

Best Times to Fish Eagle Slough

Spring (March through May) is when Eagle Slough really comes alive. The water warms, bass move shallow to spawn, and bluegill become aggressive around the weed edges. You'll see the most activity in the hour after sunrise and again in the last two hours before dark. If you're targeting spawning bass, focus on the northern end of the slough where the water tends to warm first.

Fall (September through November) is nearly as good as spring. The water cools, fish feed heavily before winter, and the slough is less crowded than it is in summer. By late October, the cattails begin to die back, which actually makes it easier to work your lure through the thicker cover. Winter fishing is possible but challenging—ice can form along the edges, and the slough can freeze solid in a hard freeze, closing access entirely.

Summer is the toughest season. The shallow water heats up quickly, and fish retreat to the deepest holes, usually near the timber piles and submerged logs on the western bank. If you fish in summer, plan to go very early—before 8 a.m.—and focus on shade and structure rather than open water.

What Tackle and Bait Work Best

The murky water at Eagle Slough means visibility is limited, so fish respond better to lures they can feel and hear. Dark-colored soft plastics—black, brown, and dark green—outperform bright colors. Spinnerbaits with Colorado blades create vibration that carries through the stained water, and they're excellent for working the weed edges. Crankbaits that rattle also work, but keep them in the 2- to 4-inch range; the slough isn't deep enough to justify diving cranks.

Live bait is often more effective than artificials here. Shiners and shad work for bass, while bluegill and small crawfish catch catfish. If you're targeting bluegill specifically, small jigs tipped with crickets or waxworms will outfish anything else. Work them slowly around the cattail stems and fallen branches—bluegill in a slough like this are not aggressive, but they're consistent.

Topwater lures can work at dawn and dusk, but they're less reliable than subsurface presentations. The water clarity and the abundance of cover mean fish often strike before they see the lure, so they're responding to the disturbance rather than the visual profile.

How to Navigate the Slough Safely

Eagle Slough is shallow and weedy, which means you need to move slowly and watch for submerged logs and stumps. A trolling motor is almost essential—it gives you precise control and won't spook fish the way a gas engine will. If you're in a johnboat, trim the motor up and use the trolling motor to ease through the weed beds. Canoes and kayaks work well here too, though they're slower and require more physical effort.

The slough has no-wake zones that are enforced year-round but especially during spring nesting season (March through June). Violating these zones can result in a fine, and more importantly, it disrupts the birds and waterfowl that the area is designed to protect. Respect the zones, and you'll have a better experience—quieter water means better fishing anyway.

Wear a personal flotation device at all times. The water is shallow, but it's also murky, and if you go overboard, you won't see the bottom. The slough is also home to snapping turtles and the occasional water moccasin, so keep your hands and feet inside the boat.

Regulations and Licensing

You need a current Indiana fishing license to fish Eagle Slough. You can purchase a one-day license, a three-day license, or an annual license through the Indiana Department of Natural Resources website or at any authorized vendor in Evansville. The cost varies depending on residency and license type, but a one-day license is inexpensive enough that it's worth buying even if you're just visiting for a few hours.

Bag limits and size restrictions vary by species. Largemouth bass have a 12-inch minimum size and a daily bag limit; bluegill and other sunfish have no size restriction but a daily bag limit of 50 combined; channel catfish have no size or bag limit. These regulations change periodically, so check the current Indiana fishing guide before you go. The guide is available on the IDNR website and at the boat ramp.

The slough is open year-round, but access can be limited during extreme weather or high water. Call ahead if you're planning a winter trip—the parking area and ramp can become impassable after heavy snow or ice.

Getting There and What to Bring

Eagle Slough Natural Area is about 10 miles north of downtown Evansville. From I-164, take the Bussing Drive exit and follow signs to the parking area. The drive from central Evansville takes about 20 minutes. There's a paved parking lot with room for several vehicles and trailers, though it can fill up on weekends during spring and fall.

Bring more water than you think you'll need—the slough has no shade in many areas, and the sun reflects off the water. A hat and sunscreen are essential. Bring insect repellent; mosquitoes can be thick in summer and early fall, especially near the cattails. A small cooler with ice keeps your catch fresh and gives you a place to store snacks and drinks. If you're fishing from a boat, bring a basic first-aid kit and a headlamp or flashlight for the ride out if you stay past sunset.

The parking area has a portable toilet but no other facilities. There's no bait shop at the slough, so buy your live bait in Evansville before you arrive. Several tackle shops near the city center stock shiners, shad, and crawfish.

Frequently Asked Questions

Can I fish Eagle Slough from the bank?

There is limited bank access along Bussing Drive, but most of the slough is surrounded by private land or protected wetland. A boat is the best way to reach the productive water. If you don't own a boat, consider renting one from a local marina in Evansville for the day.

What's the difference between Eagle Slough and the main Ohio River?

Eagle Slough is a backwater—slower, shallower, and much weaker current than the main river channel. The fish species overlap, but the slough holds more bass and bluegill, while the main river is better for catfish and sauger. The slough is also safer for small boats because there's no barge traffic.

Do I need a boat motor, or can I paddle?

You can paddle a canoe or kayak, but the slough is large enough that a trolling motor saves time and lets you cover more water. If you paddle, plan to fish the northern end where the weed beds are thickest and the fish are concentrated. Early morning is best because you'll have more energy and the water is calmer.

Is Eagle Slough good for beginners?

Yes. The fish are not particularly selective, the water is safe and slow-moving, and the slough is small enough that you won't get lost. Bluegill are especially forgiving—they'll hit almost any small bait or lure worked slowly around cover. It's a good place to learn before tackling the main river.

What should I do if I hook a large catfish?

Set the hook hard and keep your rod tip up. Catfish in the slough rarely exceed 15 pounds, but they fight hard and can wrap your line around timber. If you're using live bait, let the catfish run for a few seconds before setting—they often swallow the bait, and a delayed hook set gives you a better chance of a solid connection. Bring a net or a lip gripper; catfish have sharp spines on their pectoral fins.
