What to expect at Lake Butte des Morts

Lake Butte des Morts is a 9,000-acre shallow lake in Winnebago County, about 10 miles south of Oshkosh. The lake holds walleye, largemouth bass, smallmouth bass, northern pike, and panfish — primarily bluegill and crappie. Water depth averages 8 to 10 feet, with the deepest holes around 20 feet. The lake is heavily used by recreational boaters and anglers, especially on weekends and during summer months. Access is straightforward, regulations follow Wisconsin state law, and the fishing season runs year-round for most species, though walleye and pike have specific seasons.

The lake's shallow structure and weed growth make it productive for bass and panfish but less predictable for walleye than deeper Wisconsin lakes. Spring and fall typically produce the most consistent results. Summer fishing is possible but requires early morning or evening trips to avoid boat traffic and warm water. Winter ice fishing draws a steady crowd, particularly for panfish and pike.

  • Walleye season runs May 1 through March 31; pike season is May 1 through November 30; bass and panfish are open year-round.
  • Spring (April through May) and fall (September through October) produce the most reliable fishing; summer requires early morning or evening trips to avoid crowds.

Access and boat launches

The primary public launch is Butte des Morts Park, located on the south shore near the town of Butte des Morts. The park has a concrete ramp, parking for roughly 30 vehicles with trailers, and restroom facilities. Launch fees are minimal or free depending on county policy at the time of your visit. The ramp is usable year-round, though winter conditions may require extra caution.

Menominee Park in Oshkosh provides a second launch on the north shore. This facility is more developed, with multiple ramps, larger parking areas, and full amenities including a boat rental concession. Both launches see heavy use on weekends, so arriving early is advisable if you plan to launch during peak hours.

Shore fishing is possible at Butte des Morts Park and along some county roads on the east and west shores, though access is limited. Most productive fishing requires a boat to reach deeper holes and weed beds away from the shoreline.

Species and seasonal patterns

Walleye are the primary target for many anglers. They concentrate in the deeper holes and along weed edges, particularly during low-light periods. Spring (May and early June) and fall (September through October) are most productive. Summer walleye fishing is slower but possible in early morning or after sunset. Jigging with live minnows or soft plastics works well; trolling crankbaits along drop-offs is also effective. Walleye season runs May 1 through March 31.

Largemouth and smallmouth bass are abundant and active year-round. Largemouths favor shallow weed beds and lily pads; smallmouths prefer rocky areas and deeper structure. Spring and fall produce the most aggressive feeding. Summer bass fishing is good early and late in the day. Spinnerbaits, soft plastics, and topwater lures all work. Bass season is open year-round with no closed period.

Northern pike are present but not the lake's primary draw. They inhabit weed beds and deeper channels. Spring and fall are best; summer pike are sluggish in warm, shallow water. Large swimbaits and spoons attract pike. Pike season runs May 1 through November 30.

Panfish — bluegill, crappie, and pumpkinseed — are reliable and abundant. Bluegill bite year-round in shallow weed beds and around structure. Crappie are more seasonal, concentrating in spring and fall. Winter ice fishing for panfish is popular and productive. Small jigs, live minnows, and wax worms work well.

Regulations and licensing

All anglers age 16 and older must carry a valid Wisconsin fishing license. Licenses are sold online through the Wisconsin Department of Natural Resources website, at sporting goods stores, and at some bait shops near the lake. A three-day license is available if you do not fish regularly; annual licenses are also offered.

Daily bag limits and minimum size requirements vary by species. Walleye, pike, and bass each have specific limits and size restrictions that change periodically. Panfish typically have generous limits. Current regulations are published in the Wisconsin Fishing Regulations booklet, available free from the DNR or at license vendors. Check the current year's booklet before you fish, as rules do change.

The lake is open to public fishing under Wisconsin state law. No special permits are required beyond the standard fishing license. Ice fishing is permitted during winter months when the lake is safely frozen.

Best times to fish

Spring (April through May) is excellent for walleye, pike, and bass as they move shallow to spawn. Water temperatures are cool, and fish are aggressive. Early morning and evening are most productive, though midday can work. Expect moderate boat traffic.

Summer (June through August) is challenging for walleye but good for bass and panfish. The lake becomes crowded with recreational boaters, especially on weekends. Fish early (before 8 a.m.) or late (after 6 p.m.) to avoid crowds and take advantage of cooler water temperatures. Midday fishing is slow.

Fall (September through October) rivals spring for overall fishing quality. Walleye, pike, and bass feed aggressively as water cools. Boat traffic drops significantly after Labor Day. This is an ideal time for a trip if you can avoid peak summer weekends.

Winter (November through March) brings ice fishing for panfish and pike. The lake typically freezes by mid-December and remains solid through February. Check ice thickness before venturing out. Panfish bite consistently through the ice; pike fishing is slower but possible. Winter is the quietest season on the lake.

Bait and tackle shops nearby

Several bait and tackle shops serve the Oshkosh area and stock live bait, lures, and fishing gear. Shops in Oshkosh and the surrounding towns carry minnows, wax worms, and crawlers year-round. Many also rent boats or provide launch information. Calling ahead to confirm bait availability, especially in winter, is a good practice.

Larger sporting goods retailers in Oshkosh stock fishing tackle and licenses. Local knowledge from bait shop staff can be valuable, particularly for current conditions and recent catch reports.

What makes Lake Butte des Morts distinct

Lake Butte des Morts is a working lake — it serves as a cooling pond for a power plant and is managed for both recreation and utility purposes. This does not affect fishing, but water levels can fluctuate slightly depending on operational needs. The shallow, weedy character makes it ideal for bass and panfish but less consistent for walleye than deeper lakes in the region.

The lake's proximity to Oshkosh and easy access make it popular for day trips and weekend fishing. It is not a remote destination, and solitude is rare during summer. For anglers seeking panfish, bass, or casual walleye fishing without a long drive, it is a practical choice. For those targeting trophy walleye or seeking a quieter experience, deeper lakes farther north may be better suited.

Frequently Asked Questions

Do I need a boat to fish Lake Butte des Morts?

A boat is not required but is strongly recommended. Shore fishing is limited to a few access points, and the most productive water lies away from shore in deeper holes and weed beds. If you do not own a boat, rentals are available at Menominee Park in Oshkosh.

What is the best bait for walleye on this lake?

Live minnows (shiners or chubs) and soft plastic jigs work best. Trolling crankbaits along drop-offs is also effective, especially in spring and fall. Early morning and evening produce more bites than midday.

Is Lake Butte des Morts good for beginners?

Yes. Panfish and bass are abundant and forgiving, making them ideal for learning. The lake is shallow and easy to navigate. Walleye fishing is more technical but still possible for beginners willing to fish early or late in the day during spring and fall.

Can I fish in winter?

Yes. Ice fishing for panfish is productive and popular. Pike fishing through the ice is slower but possible. Always check ice thickness before going out, and follow current DNR safety guidelines for winter fishing.

What are the size and bag limits for walleye?

Limits vary by year and are listed in the current Wisconsin Fishing Regulations booklet. Check the DNR website or pick up a free booklet at a license vendor before your trip to confirm current rules.
