What Millers Bay offers and when to fish it
Millers Bay is a shallow, weedy extension of Lake Winnebago near Oshkosh that holds walleye, pike, and panfish in a setting that feels more intimate than the main lake. The bay runs roughly 2 miles long and averages 8 to 12 feet deep, with extensive weed beds and soft bottom—the kind of structure that concentrates fish and makes them predictable if you know the season. Spring and fall are strongest for walleye; summer brings pike and bass into the shallows; winter ice fishing produces steady panfish action.
The character of Millers Bay is different from open Winnebago. You are working confined water where boat traffic is lighter, weed cover is thicker, and fish do not roam as far. That means smaller presentations often outfish the bigger lures you might throw on the main lake, and you can cover productive water thoroughly in a single tide. The bay is also more forgiving of wind—a stiff blow that makes Winnebago rough will barely ruffle Millers Bay.
Key Takeaways
- Millers Bay holds walleye year-round but peaks in spring (April through May) and fall (September through October) when fish move into shallower weed edges.
- Pike fishing is best in summer when weeds are fully grown and provide cover; expect fish 24 to 32 inches in the deeper weed channels.
- Access is from the Oshkosh public boat launch on the main lake; you enter Millers Bay through a narrow channel that is clearly marked and navigable year-round.
- Soft plastics rigged on light jigs (1/8 to 1/4 ounce) and live shiners under a bobber are the most consistent presentations in the bay's shallow, weedy structure.
- Winter ice fishing on Millers Bay produces bluegill, crappie, and perch; the ice is typically safe by mid-December and remains solid through February.
Spring walleye fishing in the shallows
April and May are the prime months for walleye in Millers Bay. Fish move out of the main lake into the bay's shallow weed edges as water temperature climbs into the 50s. The bay's north and west shorelines warm first and hold fish earliest; by late May, walleye spread throughout the bay but remain shallow, rarely deeper than 10 feet.
Work the weed edges with a 1/8-ounce jig tipped with a soft plastic shad or a live leech. Cast parallel to the weed line rather than into it—you want to stay in the open water just off the edge where walleye hunt. Early morning and late evening are most productive, but overcast days can produce all day. If you are fishing live bait, a slip sinker rig with a live shiner under a bobber set 4 to 6 feet deep will catch walleye that are suspended over deeper holes within the bay.
Summer pike and bass in thick cover
By June, the weeds in Millers Bay are fully established and pike move in to hunt. The bay becomes a pike factory from mid-June through August. Fish the thickest weed beds with large soft plastics—7 to 9 inch swimbaits or topwater frogs—and expect strikes in water so shallow you can see the weeds from the surface. Early morning is critical; pike bite aggressively in the first two hours after sunrise, then slow considerably once the sun is high.
Bass also move into Millers Bay in summer and respond well to the same presentations. The difference is that bass will stay deeper in the weed channels (8 to 12 feet) while pike hunt the shallows. If pike action slows mid-morning, drop deeper and work the weed edges with a crankbait or a smaller soft plastic. The bay rarely gets crowded in summer, so you can work methodically through the structure without pressure from other boats.
Fall walleye and the transition to winter
September and October bring a second strong walleye bite as fish move back into the bay from the main lake. Water temperature dropping into the 60s and 50s triggers this movement. Fish are less predictable than in spring—they may be shallow one day and 12 feet deep the next—so you need to cover water vertically as well as horizontally. A jigging spoon worked on the bottom in the deeper holes will catch fish that are transitioning between shallow and deep water.
By late October, water temperature is dropping fast and the bite can be excellent for a short window. Many anglers overlook this period because they are focused on the main lake, but Millers Bay often produces better numbers of walleye in October than it does in spring. Stick with live bait—shiners or leeches—and fish the deepest holes in the bay (12 to 14 feet) as the month progresses.
Winter ice fishing for panfish and perch
Millers Bay freezes solid by mid-December and remains fishable through February. The bay is shallower than most of Winnebago, so ice forms earlier and lasts longer. Bluegill and crappie congregate in the deeper holes (10 to 14 feet) and bite steadily on small jigs tipped with waxworms or maggots. Perch are also present and will hit a small spoon or a live minnow under a bobber.
Set up over the deeper weed channels and holes—a GPS unit or a map will help you locate them under the ice. Drill multiple holes and move between them; panfish often school tightly, so finding the school is half the battle. The bite is typically best in the first hour after sunrise and again in the last hour before sunset, though midday can produce if you are over the right spot.
Access and launch information
Millers Bay is accessed from the Oshkosh public boat launch on Lake Winnebago. The launch is located at the Oshkosh Marina, which sits on the main lake near downtown Oshkosh. From the launch, you enter Millers Bay through a marked channel that is roughly 0.5 miles long and clearly navigable. The channel is dredged and maintained, so even shallow-draft boats can navigate it without difficulty.
Parking at the Oshkosh Marina is ample, and the launch itself is well-maintained with multiple lanes. There is a small launch fee (the amount varies by season and is set by the City of Oshkosh). The marina also has fuel, bait, and tackle available if you need to resupply. In winter, the launch remains accessible for ice fishing; you can drive directly onto the ice once it is deemed safe by local authorities, typically by mid-December.
Tackle and technique for Millers Bay conditions
Millers Bay rewards anglers who think small and precise. The water is shallow and clear, and fish can see your presentation from a distance. Use 1/8 to 1/4 ounce jigs in natural colors—green, brown, and black—tipped with soft plastics or live bait. A 6-foot medium-light spinning rod with 6 to 8 pound test line is ideal for walleye and panfish; if you are targeting pike, step up to 8 to 10 pound test and a medium rod.
Live bait is often more effective than artificials in Millers Bay, especially for walleye. Shiners, leeches, and crawfish are all available at local bait shops in Oshkosh. A slip sinker rig or a simple bobber rig will outfish fancy presentations in the bay's shallow, weedy structure. For pike and bass, soft plastics and topwater lures are most productive, but do not overlook a simple live shiner under a bobber—pike will crush it.
Frequently Asked Questions
Can I fish Millers Bay year-round?
Yes. Open water fishing runs from spring through fall, and ice fishing is solid from mid-December through February. The bay is less crowded than the main lake in all seasons, which makes it a good choice if you want to avoid heavy boat traffic.
What is the best time to fish Millers Bay for walleye?
Spring (April and May) and fall (September and October) are strongest. Spring fish are shallow and predictable; fall fish are deeper and require more vertical jigging, but the bite can be excellent if you find the right holes.
Do I need a special permit to fish Millers Bay?
No. A Wisconsin fishing license is required, just as it is for any public water in the state. The bay is part of Lake Winnebago and is open to public fishing under the same regulations.
What size pike can I expect in Millers Bay?
Pike in the bay typically range from 20 to 32 inches, with occasional fish over 35 inches. The shallow, weedy structure produces plenty of 24 to 28 inch fish that are fun to catch and good eating.
Is Millers Bay good for beginners?
Yes. The bay is shallow, confined, and forgiving. You can cover productive water thoroughly without traveling far, and the fish are predictable if you match the season. It is an excellent place to learn walleye and pike fishing without the complexity of open Winnebago.
