What You'll Find at Songbird Slough

Songbird Slough Forest Preserve is a 1,200-acre wetland and woodland preserve in Will County, about 35 miles southwest of Chicago near the town of Wilmington. The preserve centers on a shallow slough — a slow-moving waterway bordered by marsh, sedge meadow, and bottomland forest — that holds largemouth bass, bluegill, and channel catfish. The water is typically murky and weedy, which means you'll be fishing structure-heavy habitat rather than open water.

Access is limited and managed. The preserve has no developed boat launch, and the Illinois Department of Natural Resources restricts motorized boats on the slough itself. Most fishing here is done from shore or by canoe and kayak, which means you're working smaller sections at a time and fishing quieter than you would at a reservoir. The preserve is part of the Salt Creek Greenway system, and it draws fewer anglers than the larger state parks in the region, which can mean less pressure on the fish but also fewer amenities.

Key Takeaways

  • Songbird Slough holds largemouth bass and bluegill in shallow, weedy water best fished from shore or by canoe.
  • No motorized boats are permitted on the slough, and there is no developed boat launch at the preserve.
  • The preserve is open year-round, but spring and fall offer the most consistent fishing when water levels and temperatures favor active fish.
  • You must have a valid Illinois fishing license, and the slough is catch-and-release for bass in some sections depending on current regulations.
  • Parking is available at the main preserve entrance off Kankakee Street, but facilities are minimal — bring water and plan to be self-sufficient.

When to Fish Songbird Slough

Spring (April through May) is the strongest season. Water temperatures climb into the 60s and 70s, bass move shallow to spawn, and bluegill become aggressive around structure. Early morning and late afternoon produce the most strikes. The slough can be weedy by late May, which makes casting difficult but concentrates fish in clearer pockets.

Summer (June through August) is slower. Water warms into the 80s, and fish retreat to deeper holes and dense vegetation. If you fish summer, focus on early morning before 8 a.m. and after 6 p.m., and work the deepest, shadiest sections you can reach. Bluegill will still bite in the shallows at dawn.

Fall (September through October) picks up again. Water cools, fish become more active across the slough, and the weed growth dies back enough to make casting easier. October is often as good as spring. Winter fishing is possible but slow — water temperatures drop into the 40s, and fish are lethargic. Most anglers skip winter here.

Species and What to Expect

Largemouth bass are the primary target. They range from 12 to 18 inches on average, with occasional fish pushing 20 inches. They hold in the thickest weeds, around fallen trees, and in the deeper holes of the slough. Topwater lures and soft plastics work best in spring; in summer, switch to deeper-running crankbaits and jigs. The slough is shallow enough that you can often see where bass are holding if you move slowly and look for disturbance in the weeds.

Bluegill are abundant and willing. They school in the shallows, especially around cattails and submerged brush. A simple ultralight rod with a small jig or live cricket will produce steady action. Bluegill here average 6 to 8 inches, and they're good eating if you want to keep a few for dinner.

Channel catfish are present but less commonly targeted. They're most active at night and in summer. If you want to fish for them, use chicken liver or cut shad and fish the bottom in the deepest sections after dark.

Access, Parking, and Regulations

Songbird Slough Forest Preserve is located at 23963 Kankakee Street in Wilmington. Parking is available at the main entrance lot, which is free. The lot is small — typically 10 to 15 spaces — and can fill on weekends, especially in spring. There are no restrooms, no concessions, and no rental facilities. Bring everything you need: water, food, bug spray, and a headlamp if you plan to fish into dusk.

You must have a valid Illinois fishing license to fish the slough. Licenses are sold online through the Illinois Department of Natural Resources website, at sporting goods stores, and at some bait shops in the Wilmington area. A one-day license costs less than a full-year license if you're visiting once.

Current regulations require catch-and-release for largemouth bass in certain sections of the preserve; check the IDNR website or call the Will County Forest Preserve District before you go to confirm which areas are under which rules. Bluegill and catfish have standard state limits. No motorized boats are permitted on the slough. Canoes and kayaks are allowed, but launching is by hand-carry only — there is no ramp.

How to Fish the Slough from Shore

Most anglers fish Songbird Slough from the shoreline, which means you're limited to the edges and whatever you can reach by casting. The best approach is to walk the perimeter slowly, casting into the weeds and around any visible structure. A 6- to 7-foot medium-power rod with 10- to 15-pound braid handles the thick vegetation without breaking off.

Focus on the transitions: where open water meets dense weeds, where fallen trees cross the water, and where the slough narrows. Bass hold in these spots waiting for baitfish. Work topwater lures early in the morning — a popper or walking bait creates disturbance that bass respond to in shallow water. As the sun climbs, switch to soft plastics rigged on a jighead and fish them slowly through the weeds.

The slough is roughly 2 to 4 feet deep in most places, with deeper holes near the center. You don't need a boat to reach productive water — the shoreline itself is productive. Patience and quiet movement matter more than distance.

Canoe and Kayak Fishing

If you bring a canoe or kayak, you can access the middle of the slough and fish both sides. Hand-carry your boat from the parking area to the water — there is no launch ramp. The slough is narrow enough (typically 50 to 100 feet wide) that you can paddle from one bank to the other and fish both edges in a single trip.

Kayaks are more stable for fishing than canoes in this environment because you sit lower and can cast from a seated position without tipping. Bring a small anchor or stake if you want to hold position in current or wind. The slough is slow-moving, so drift is minimal, but wind can push you around. Wear a life jacket — the water is murky and cold, especially in spring and fall.

Nearby Fishing and Services

Songbird Slough is part of a larger network of Will County preserves and state fishing areas. Kankakee River State Park, about 10 miles north, offers boat launches, developed parking, and fishing for catfish and bass in a larger, more open setting. Wilmington State Fish and Wildlife Area is closer and has similar habitat to Songbird Slough but with more developed access.

The nearest bait and tackle shop is in Wilmington, about 5 miles from the preserve. Gas stations and fast food are available along Route 66 near Wilmington. There are no lodging options at the preserve itself; the nearest hotels are in Joliet, about 20 miles north.

Frequently Asked Questions

Do I need a boat to fish Songbird Slough?

No. Most anglers fish from shore, and shore fishing is productive. If you want to access the middle of the slough, a canoe or kayak works, but there is no motorized boat launch and no rental available at the preserve.

What's the best lure for bass here?

Topwater lures and soft plastics work best. In spring, use poppers or walking baits early in the morning. In summer and fall, switch to jigs and crankbaits that you can fish through the weeds slowly. Live shiners or crawfish also work if you want to use bait.

Can I keep fish from Songbird Slough?

Bluegill and catfish can be kept within state limits. Largemouth bass are catch-and-release in some sections of the preserve. Check the Illinois Department of Natural Resources website or call the Will County Forest Preserve District to confirm the current rules for the section you plan to fish.

Is Songbird Slough crowded?

No. It draws far fewer anglers than larger state parks and reservoirs in the region. Spring weekends can see a handful of other fishermen, but you'll rarely feel crowded. Weekday fishing is often solitary.

What should I bring that isn't obvious?

Bug spray (mosquitoes are heavy in summer and fall), a headlamp or flashlight if you fish into dusk, and plenty of water. There are no facilities at the preserve. Wear waders or waterproof boots if you plan to wade the shallows — the bottom is soft and muddy.
