What Mueller's Lake offers and who should fish it

Mueller's Lake is a shallow, weedy impoundment in central Wisconsin that holds walleye, northern pike, and largemouth bass. The lake runs roughly 200 acres and sits in a region of heavy vegetation and soft bottom — conditions that make it productive for walleye in spring and fall, and a solid pike fishery year-round. The water clarity is typically stained to murky, which means fish relate closely to structure and vegetation rather than roaming open water.

This lake suits anglers who fish shallow-water techniques and don't mind working through weeds. Trolling crankbaits, casting soft plastics into vegetation, and jigging in the deeper holes (which still max out around 20 feet) all produce. The lake is less crowded than larger regional destinations, which can be an advantage during peak season. If you prefer clear-water sight-fishing or deep-structure jigging, you'll find better options elsewhere in Wisconsin.

Key Takeaways

  • Mueller's Lake holds walleye, northern pike, and largemouth bass in a shallow, weedy system where vegetation and soft bottom dominate the structure.
  • Spring and fall are the strongest walleye seasons; pike bite consistently year-round but are most aggressive in cooler months.
  • Shallow-water techniques — casting into weeds, trolling crankbaits, and jigging vegetation edges — outperform deep-water methods on this lake.
  • Public access is available via a boat launch; check current Wisconsin fishing regulations for season dates and daily bag limits before you go.

Walleye fishing in spring and fall

Walleye on Mueller's Lake move shallow in spring as water temperatures climb from the mid-40s into the 50s. Early season (April through May) concentrates fish on the deeper edges of weed beds and in the few holes that reach 15 to 20 feet. Jigging with live minnows or soft plastics in 8 to 12 feet of water produces steady catches. Work the transitions where vegetation thins out or where bottom composition changes from silt to firmer ground.

Fall (September through October) mirrors spring conditions and often produces better numbers because the entire lake cools evenly. Walleye spread across more of the lake as vegetation dies back, making them easier to locate. Trolling crankbaits along weed edges and over the deeper holes works well during this window. Early morning and low-light periods are most productive; midday fishing slows considerably.

Summer walleye fishing is possible but requires patience. Fish move into the deepest holes and the thickest vegetation during the day, becoming active only at dawn, dusk, and after dark. Many anglers skip Mueller's in July and August in favor of clearer, deeper lakes where daytime fishing is more reliable.

Northern pike year-round

Northern pike are Mueller's Lake's most consistent target. They hunt the weed beds throughout the year and respond well to larger lures — 4- to 6-inch crankbaits, spinnerbaits, and soft plastics in the 5- to 7-inch range. Spring and fall pike are aggressive and bite during daylight hours. Winter pike fishing is productive if you're willing to cut holes and jig; the lake's shallow depth means ice-out can be unpredictable, so confirm conditions before committing to a winter trip.

Summer pike fishing requires heavier cover. Fish the thickest weed beds early and late in the day, or switch to night fishing when the water warms. Casting dark-colored lures into vegetation and working them slowly produces strikes. Pike in shallow, weedy lakes often hold tight to cover, so accuracy matters more than distance.

Access and launch facilities

Mueller's Lake has a public boat launch managed by the local county or town authority. The launch is a single-lane concrete ramp suitable for small to mid-size boats. Parking is limited, so arrive early during weekends. There are no fuel docks or rental facilities on the lake, so bring a full tank and any supplies you'll need for the day.

The surrounding area is residential and agricultural, with limited services nearby. The nearest town with gas, food, and lodging is a short drive away. Cell service is spotty on the water, so plan your route and tell someone where you're fishing before you launch.

Seasons and regulations

Wisconsin's general inland fishing season runs from the Saturday of Memorial Day weekend through March 31 the following year, though some species have different opener dates. Walleye season typically opens in early May; pike and bass follow the general season. Daily bag limits and size restrictions vary by species and change year to year, so check the current Wisconsin Department of Natural Resources (WDNR) fishing guide before you fish.

A Wisconsin fishing license is required for anyone 16 and older. Licenses are sold online through the WDNR website, at bait shops, and at many sporting goods retailers. A one-day license is available if you're visiting from out of state and don't want to commit to a full season.

What to bring and how to fish it

Pack a shallow-water tackle box: crankbaits in the 2- to 4-inch range, spinnerbaits, soft plastics (4 to 7 inches), and jigs in 1/4- to 1/2-ounce weights. Bring live minnows if you plan to jig; a small aerator keeps them fresh. A weed guard on your hooks reduces snags in the heavy vegetation. A GPS or map of the lake helps you locate the few deeper holes and identify weed-bed edges.

Polarized sunglasses help you spot structure and shallow fish, especially on clear days. Wear a personal flotation device — shallow lakes with heavy vegetation can be disorienting if you're unfamiliar with the layout. Bring more water and snacks than you think you'll need; there's nowhere to resupply on the water.

When to fish Mueller's Lake

Spring (April through May) and fall (September through October) are the most productive windows for both walleye and pike. Water temperatures are in the comfortable range for active feeding, and fish are shallow enough that you don't need specialized deep-water gear. Early morning and late afternoon produce better than midday, especially in spring and fall.

Summer fishing is possible but requires more effort and patience. If you're planning a trip in June, July, or August, fish at dawn, dusk, or after dark. Winter fishing is viable if ice conditions are safe; confirm ice thickness and current conditions with local bait shops before you go.

Frequently Asked Questions

What's the best lure for pike on Mueller's Lake?

Larger crankbaits (3 to 4 inches) and spinnerbaits in black, chartreuse, or natural colors work consistently. Pike in weedy lakes often prefer slower presentations, so work your lure deliberately rather than fast. Soft plastics rigged on jig heads also produce, especially in heavy cover.

Can I fish Mueller's Lake in winter?

Yes, if ice conditions are safe. The lake's shallow depth means ice-out can be unpredictable, so check with local bait shops or the WDNR for current conditions. Pike fishing through the ice is productive; walleye fishing requires patience and the right holes.

Do I need a boat to fish Mueller's Lake?

A boat is the most practical way to access the lake's best structure. Shore fishing is possible near the launch and along accessible banks, but you'll cover more water and find more fish from a boat. Kayaks work for anglers willing to navigate shallow, weedy water carefully.

What size fish can I expect?

Walleye typically run 12 to 16 inches, with occasional fish pushing 18 inches. Pike average 18 to 24 inches; fish over 30 inches are possible but not common. Bass are generally smaller, in the 10- to 14-inch range. Check the current WDNR regulations for minimum size requirements before you fish.

Is Mueller's Lake crowded?

Mueller's Lake sees moderate pressure, especially on weekends during spring and fall. It's less crowded than larger regional lakes, which can work in your favor. Weekday fishing and early morning trips offer the best chance to fish without competition.
