What You'll Find at Goose Island County Park

Goose Island County Park sits on the western shore of Green Bay near Seymour, Wisconsin, offering access to one of the Great Lakes' most productive walleye and pike fisheries. The park provides a boat launch, shoreline access, and basic facilities on a small peninsula that juts into the bay. Most anglers fish the deeper water immediately offshore or work the shallow bays and weed edges that surround the park, where walleye, northern pike, and panfish hold year-round.

The park is small—roughly 30 acres—but its location on Green Bay's western shore puts you within casting distance of productive structure. The bottom transitions quickly from shallow sand and gravel near shore to deeper basins, and that transition zone holds fish in most seasons. Access is straightforward: a public boat launch, parking for trailers, and a few picnic areas. There is no lodge, bait shop, or fuel on-site, so plan accordingly.

Key Takeaways

  • Walleye fishing peaks in spring (April through May) and fall (September through October), with fish holding on the deeper edges and structure just offshore.
  • Northern pike are present year-round and often caught incidentally while targeting walleye, especially in shallow bays and around weed beds in summer.
  • The boat launch is the only public access point; there is no shoreline fishing area or pier, so a boat is required to fish effectively.
  • Wisconsin fishing licenses and Green Bay-specific regulations apply; walleye and pike have separate bag limits and size restrictions that change annually.
  • Summer can be crowded with recreational boaters, so early morning or evening trips often provide better fishing and fewer conflicts.

Seasons and What to Expect

Spring (April through May) is the most reliable season for walleye. Fish move shallow to spawn and feed heavily before and after the spawn, and the water is cool enough that they remain active throughout the day. Jigs tipped with live minnows or soft plastics work well in 8 to 15 feet of water along the drop-offs that run parallel to the shoreline. Early morning and late evening are most productive, but spring walleye will bite during midday if you stay on structure.

Summer (June through August) sees walleye move deeper as water temperatures climb. Fish retreat to the basin edges and deeper structure, typically 20 to 40 feet down. Trolling crankbaits or live-bait rigging with slip sinkers becomes more effective than casting. Pike fishing improves in summer, particularly in the shallow bays and weed edges where they hunt. Panfish—bluegill, crappie, and perch—are abundant in shallow water and provide consistent action if walleye are slow.

Fall (September through October) brings another strong walleye bite as water cools and fish move back to shallower structure. The pattern resembles spring: jigs and live bait in 10 to 20 feet of water produce well. October can be excellent, though weather becomes unpredictable and the park can be windy. Winter fishing is possible but requires ice-fishing equipment and knowledge of safe ice conditions; check with local authorities before heading out.

Species and Fishing Methods

Walleye are the primary target. They respond to live-bait presentations—jigs tipped with shiners or minnows, or slip-sinker rigs with live bait drifted along drop-offs. Casting small crankbaits or soft plastics also works, especially in spring and fall. Walleye are most active at dawn, dusk, and during low-light conditions, though they will bite throughout the day if you fish deep structure or cloudy weather.

Northern pike are common and often caught while walleye fishing. They prefer larger baits and flashier presentations—spinnerbaits, large crankbaits, or live shiners in the 6- to 8-inch range. Pike concentrate in shallow bays and around weed beds in summer, and move to deeper edges in fall and winter. A wire leader or heavy fluorocarbon is recommended to prevent bite-offs.

Panfish—bluegill, crappie, and yellow perch—are abundant and provide reliable action. Small jigs, live minnows, and wax worms work well in shallow water (5 to 12 feet). Panfish are less seasonal than walleye and pike; they bite year-round, though summer and fall are most productive. Kids and beginners often have success targeting panfish while more experienced anglers pursue walleye.

Access, Facilities, and Regulations

Goose Island County Park has a public boat launch suitable for trailers up to about 20 feet. The launch is maintained by Outagamie County and is open year-round, though winter access depends on snow removal and ice conditions. There is parking for vehicles with trailers, a few picnic tables, and vault toilets. No fuel, bait, or tackle shop is on-site; the nearest services are in Seymour, roughly 5 miles away.

Wisconsin fishing licenses are required for anyone 16 and older. A Green Bay-specific stamp is also required if you fish Green Bay proper (as opposed to inland lakes). Walleye and pike have separate bag limits and minimum size requirements that vary by year; check the current Wisconsin Department of Natural Resources (DNR) fishing regulations before you go. Panfish typically have higher bag limits and no minimum size.

The park is day-use only; there is no camping. Hours vary seasonally, so confirm with Outagamie County Parks before planning an early-morning or evening trip. Alcohol is permitted in designated areas. Dogs are allowed on leash. The park can be windy and exposed, especially in fall and winter, so dress for conditions and monitor weather forecasts.

Getting There and Nearby Options

Goose Island County Park is located at N8055 County Road QQ, Seymour, Wisconsin 54165. From Green Bay, take Highway 29 east toward Seymour, then follow local roads north to the park. GPS coordinates are approximately 44.5°N, 88.3°W. The drive from downtown Green Bay is roughly 30 to 40 minutes depending on traffic.

If Goose Island is crowded or conditions are poor, nearby alternatives include Pensaukee River access points (also on Green Bay's western shore) and inland lakes in the Seymour area. The Lower Fox River, which feeds Green Bay, offers walleye and pike fishing as well, though it requires different techniques and has its own regulations. Local bait and tackle shops in Seymour or Green Bay can advise on current conditions and alternative spots.

What to Bring and How to Prepare

Bring a boat suitable for Green Bay conditions—a 16-foot center console or larger is ideal, as the bay can develop rough water quickly. Pack a depth finder or GPS to locate structure and navigate safely. Bring more water and snacks than you think you'll need; there are no services at the park. A first-aid kit, sunscreen, and a hat are essential, especially in spring and fall when sun reflection off water intensifies UV exposure.

Check the Wisconsin DNR website for current bag limits, size restrictions, and any special regulations for Green Bay. Confirm the park's hours and launch conditions before you leave home. If you are unfamiliar with Green Bay, consider hiring a local guide for your first trip; they know the structure, seasonal patterns, and current conditions far better than any general guide can convey. Weather on Green Bay can change rapidly, so monitor forecasts and do not hesitate to stay ashore if conditions look unsafe.

Frequently Asked Questions

Do I need a boat to fish Goose Island County Park?

Yes. The park has no shoreline fishing area or pier. A boat is required to reach productive water. The public launch accommodates trailers, or you can rent a boat from nearby marinas in the Green Bay area.

What is the best time of year to fish here?

Spring (April through May) and fall (September through October) are most reliable for walleye. Summer offers good pike and panfish fishing but requires deeper presentations and patience. Winter is possible but demands ice-fishing knowledge and safe ice conditions.

Are there size or bag limits I need to know about?

Yes. Wisconsin sets annual bag and size limits for walleye and pike that vary by year and sometimes by zone. Check the current DNR fishing guide before you fish. Panfish typically have higher bag limits. A Green Bay stamp is required in addition to your state license.

Can I fish at night?

Night fishing is legal in Wisconsin, but the park's day-use-only policy means you must leave by sunset or the posted closing time. Confirm hours with Outagamie County Parks before planning a twilight or evening trip.

Is the boat launch open in winter?

The launch is maintained year-round, but winter access depends on snow removal and ice conditions. Contact Outagamie County Parks to confirm conditions before making a winter trip.
