What the Suamico River offers anglers

The Suamico River is a short, productive warmwater system that drains into Green Bay just north of the city of Green Bay. It runs roughly 20 miles from its headwaters near Seymour south to the bay, passing through a mix of wooded banks, marshland, and residential areas. The river holds walleye, northern pike, and panfish—mainly perch and bluegill—in numbers that make it worth a half-day trip if you're already in the Green Bay area or live within an hour's drive.

What makes the Suamico distinct from other Green Bay tributaries is its accessibility and the consistency of its fish. You don't need a boat to fish most of it; shore access is available at several public landings and parks. The lower river, especially the stretch from the Suamico Dam down to the bay, holds the largest walleye and pike. The upper river and its backwater areas are better for panfish and smaller pike, and they're less crowded on weekends.

Key Takeaways

  • The Suamico River holds walleye, pike, and panfish in the lower section near Green Bay, with shore access at public landings making it fishable without a boat.
  • Walleye bite best in spring (April through early June) and fall (September through October) on live shiners, crawlers, and small jigs near deeper holes and current breaks.
  • Pike are present year-round but most active in spring and fall; they respond to larger baits and lures, especially around weed edges and woody cover.
  • The upper river and backwater areas hold panfish and are less pressured than the lower river, making them a good choice on busy weekends.
  • Wisconsin fishing regulations apply; you need a valid license, and walleye and pike have size and bag limits that change annually—check the current Wisconsin DNR regulations before you fish.

Walleye fishing in the lower river

The lower Suamico, from the dam down to where it meets Green Bay, is where most anglers focus for walleye. This section has deeper holes, current, and structure—all things walleye want. The best fishing happens in spring, roughly mid-April through May, when walleye move into the river from the bay to spawn. Fall, from late September through October, is nearly as good; the water cools, walleye become more active, and they're less scattered than they are in summer.

Live shiners and crawlers work well fished on a simple slip-sinker rig or a jig head. Cast near the dam, around the pilings of old structures, and along the outside bends where the current has carved deeper water. Early morning and dusk are most productive, but walleye in this river will bite through the middle of the day if you're fishing deep enough. Summer fishing is slower; walleye retreat to deeper water in Green Bay itself, and only a few stay in the river. If you do fish summer, focus on the deepest holes and fish at night.

Pike and their seasonal patterns

Northern pike are present in the Suamico year-round, but spring and fall are when they're most aggressive and easiest to find. In spring, pike move shallow to spawn, and you'll find them in the backwater areas and along weed edges. Fall pike are feeding hard before winter and will chase larger baits and lures. Use larger shiners (6 to 8 inches), small soft plastics, or spinnerbaits. Pike don't require the precision that walleye do; they're more likely to chase a lure and less likely to refuse it because it's not exactly the right color.

Summer pike are scattered and less predictable. Some hold in the deeper holes of the lower river; others retreat to the backwaters where there's shade and cooler water. Winter fishing is possible but requires a different approach—tip-ups with live bait under the ice, fished in the deeper sections. The Suamico doesn't freeze as solid as inland lakes, so check ice conditions before you go.

Panfish and the upper river

If you want to catch numbers of fish and don't mind smaller sizes, the upper Suamico and its backwater areas are worth exploring. Yellow perch and bluegill are abundant here, and they bite consistently on small jigs tipped with waxworms or minnows, or on live crawlers. You can fish from shore at several points, and the water is shallow enough that you don't need a deep-water sounder to find them.

Panfish bite best in spring and early summer, but they're active through fall as well. The upper river is also less crowded than the lower section, which means you'll have more room to move and explore. If you're bringing kids or want a relaxing afternoon without the pressure of targeting trophy fish, this is the right part of the river.

Access points and where to launch

The Suamico River has several public landings and shore-access points. The main boat launch is at Suamico River Park, located off Riverside Drive in the town of Suamico. This is a small, two-lane launch suitable for small to medium boats; it can get crowded on weekends. From here, you can fish upstream toward the dam or downstream toward Green Bay.

If you want to fish from shore, there's access at the Suamico Dam area (check with the town for parking and access rules), and several smaller parks along the lower river offer bank fishing. The river is narrow enough that wading is possible in many sections, especially in summer when water levels drop. Wear a life jacket if you're wading; the current can be stronger than it looks, especially near the dam.

Seasonal timing and what to expect

Spring (April through May) is the most reliable season. Walleye are in the river, pike are shallow and aggressive, and panfish are spawning and feeding. Water temperatures are cool, and the river is usually running high from snowmelt. Expect crowds at the public launch on weekends.

Summer (June through August) is slower for walleye and pike but can be good for panfish. The river warms, and most of the larger fish move into Green Bay or retreat to the deepest holes. If you fish summer, go early in the morning or at night. Fall (September through October) rivals spring for walleye and pike fishing. Water temperatures drop, fish become active again, and the crowds thin out. Winter fishing is possible but requires ice-fishing gear and a willingness to deal with unpredictable ice conditions.

Regulations and what you need to know

Wisconsin fishing regulations apply on the Suamico River. You need a valid Wisconsin fishing license, which you can purchase online through the Wisconsin Department of Natural Resources website or at most bait and tackle shops. Walleye and pike have size and bag limits that vary by year; check the current Wisconsin DNR fishing regulations before you go. Panfish typically have generous limits, but confirm the current rules.

The river is open to public fishing, but respect private property along the banks. Some sections flow through residential areas, and trespassing will get you asked to leave. Stick to public landings and marked access points. If you're planning to fish from a boat, make sure your vessel is registered and that you have the required safety equipment.

Frequently Asked Questions

Do I need a boat to fish the Suamico River?

No. Shore access is available at public landings and parks, and much of the river is fishable from the bank. A boat gives you more water to cover and access to deeper holes, but it's not required for a productive day.

What's the best time of year to catch walleye?

Spring (mid-April through May) and fall (late September through October) are most reliable. Walleye move into the river during these seasons and bite consistently. Summer is slower; most walleye retreat to deeper water in Green Bay.

Can I catch pike year-round?

Yes, pike are present year-round, but spring and fall are when they're most active and easiest to find. Summer pike are scattered and less predictable. Winter fishing is possible under the ice but requires specialized gear.

What size fish can I expect?

Walleye typically run 12 to 18 inches, with occasional fish over 20 inches. Pike average 18 to 24 inches, with some reaching 30 inches or more. Panfish are generally 6 to 10 inches. The lower river tends to hold larger fish than the upper river.

Is the Suamico River better than other Green Bay tributaries?

It depends on what you're after. The Suamico is accessible from shore, holds consistent numbers of fish, and is less crowded than some other nearby rivers. If you want trophy walleye, the lower Fox River or Green Bay itself may offer better odds, but the Suamico is a solid choice for a half-day trip.
