What Korth Lake offers anglers

Korth Lake is a shallow, 200-acre impoundment in Shawano County that holds walleye, northern pike, and largemouth bass. The lake averages 8 to 10 feet deep with a maximum depth around 20 feet, making it a classic warm-water reservoir where fish relate closely to structure and vegetation. Because it's shallow and productive, Korth responds quickly to seasonal changes—spring and fall are often more reliable than summer, when the fish move deeper or suspend in the thermocline.

The lake sits in agricultural country with limited public access, so knowing where you can launch and fish legally matters before you go. The character of Korth is different from the deeper, clearer lakes elsewhere in Shawano County; it's murkier, more weedy, and better suited to anglers who fish structure deliberately rather than those who prefer open-water trolling.

Key Takeaways

  • Korth Lake is a 200-acre shallow reservoir averaging 8 to 10 feet deep, best for walleye and pike in spring and fall when fish are active in the shallows.
  • Public access is limited; confirm launch locations and parking before you arrive, as the lake is surrounded mostly by private land.
  • Vegetation, fallen timber, and the transition zones between shallow and deeper water hold the most fish year-round.
  • Wisconsin fishing regulations apply; you will need a current Wisconsin fishing license and must follow walleye and pike harvest limits for Shawano County.

When to fish Korth Lake

Spring (April through May) is often the most productive season. Walleye move into shallow water to spawn and feed heavily before and after the spawn. Pike are also active and aggressive, and you can find both species in 4 to 8 feet of water near vegetation and woody cover. Early morning and evening are best, but overcast days can produce all day.

Summer (June through August) is slower. The lake warms quickly because of its shallow profile, and fish move to deeper holes, suspended structure, or the thickest vegetation. If you fish summer, focus on early morning before the sun climbs, or fish at night when walleye move back into the shallows to feed. Jigs tipped with live bait or soft plastics work better than crankbaits in the heat.

Fall (September through October) is nearly as good as spring. Water cools, fish become active again, and they move back into shallow feeding zones. This is an excellent time for pike, which are aggressive and visible in the shallows. Winter (November through February) is possible but challenging; ice fishing requires current conditions and safety gear, and the bite is typically slower than on deeper lakes.

Structure and habitat on Korth Lake

Vegetation is the dominant feature. Korth has extensive beds of coontail, milfoil, and emergent cattails, especially along the north and west shorelines. These weeds hold walleye and pike year-round, but they also make fishing difficult if you're not prepared for snags. Use weedless jigs, Texas-rigged soft plastics, or topwater lures that can be worked through the vegetation without hanging up constantly.

Fallen timber and brush piles are scattered throughout the lake, particularly in the deeper basins. These are prime ambush points for pike and holding areas for walleye during the day. If you know where trees have fallen or where old structure exists, mark those spots and return to them in different seasons.

The transition zone between shallow flats (4 to 6 feet) and the deeper basin (15 to 20 feet) is a natural travel corridor. Fish move along these edges to feed and rest. Early and late in the day, work the shallow side of the transition; during midday, focus on the deeper side where fish retreat from light and heat.

Access and launch points

Public access to Korth Lake is limited. The most reliable launch point is the Korth Lake public boat landing, located on the south side of the lake. This is a small, basic facility with a gravel ramp and limited parking. Arrive early during peak seasons, as spaces fill quickly on weekends.

Confirm current access conditions before you go, as water levels, ramp conditions, and parking availability can change seasonally. Contact the Shawano County Parks Department or check the Wisconsin Department of Natural Resources website for updates. Some anglers fish from shore along public rights-of-way, but most of the shoreline is private; do not trespass.

Tackle and techniques for Korth Lake

For walleye, jigs are the most consistent choice. Use 1/4- to 3/8-ounce jigs tipped with live minnows (shiners or chubs) or soft plastics in natural colors—white, chartreuse, or brown. Work the jigs slowly along the bottom and through vegetation, pausing frequently to let the bait sit. Slip sinker rigs with live bait are also effective, especially in spring when fish are shallow and feeding actively.

For pike, larger presentations work better. Spinnerbaits, crankbaits, and topwater lures in bright colors (chartreuse, orange, white) draw strikes. Pike are less selective than walleye and will chase moving baits. Cast near vegetation and along the edges of deeper water, and work the lure with steady retrieves or jerky, erratic movements that trigger aggression.

Soft plastics rigged on 1/2-ounce jigs are versatile for both species and work well in weedy conditions. Stick baits and swimbaits in 4- to 6-inch lengths are particularly effective for pike. Use a rod with a sensitive tip so you can feel the bottom and detect strikes in heavy cover.

Regulations and licensing

Wisconsin fishing regulations apply to Korth Lake. You must have a current Wisconsin fishing license, which you can purchase online through the Wisconsin Department of Natural Resources website or at most bait and tackle shops. Licenses are available for one day, three days, or a full year.

Walleye and pike harvest limits vary by waterbody and season. For Shawano County, check the current Wisconsin fishing regulations guide or the DNR website before you fish to confirm the daily bag limit, minimum size, and any special restrictions. Regulations change, so do not rely on information from previous years.

Catch-and-release is always an option and is encouraged on lakes where populations are recovering or where anglers want to preserve the fishery for future trips. If you keep fish, handle them carefully and keep them on ice or in a livewell to maintain quality.

Frequently Asked Questions

What is the best time of day to fish Korth Lake?

Early morning (one hour before sunrise to mid-morning) and evening (two hours before sunset through dark) are most productive. Walleye and pike are most active during low-light periods. Overcast days can produce throughout the day because cloud cover reduces light penetration and keeps fish active in the shallows.

Can I fish Korth Lake in winter?

Yes, ice fishing is possible when the lake is safely frozen, typically from December through February. Check ice thickness (at least 4 inches for walking, 5 to 7 inches for small equipment) before you venture out. Winter walleye fishing can be productive, but the bite is often slower than in spring and fall. Jigging with live minnows under the ice is the most common technique.

What size fish can I expect to catch?

Walleye typically range from 12 to 18 inches, with occasional fish over 20 inches. Pike are often larger, with many fish in the 18- to 28-inch range and some exceeding 30 inches. Largemouth bass are present but less abundant; most run 12 to 16 inches. Actual sizes vary year to year depending on water conditions and fishing pressure.

Is Korth Lake good for beginners?

Korth can be challenging for beginners because of heavy vegetation and limited access, but it is not impossible. Start in spring when fish are shallow and active, use simple jig-and-minnow presentations, and fish the edges of weed beds rather than trying to work through dense cover. Consider hiring a local guide for your first trip to learn the lake's structure and productive areas.

Do I need a boat to fish Korth Lake?

A boat gives you access to more water and structure, but shore fishing is possible along public areas. From shore, focus on the public landing area and any accessible points where vegetation is thinner. A boat allows you to reach deeper water, navigate around weeds, and cover more ground, which increases your chances of finding active fish.
