What Lake Thompson offers walleye and pike anglers

Lake Thompson is a shallow, weedy 1,100-acre lake about 15 minutes south of Rhinelander that holds solid populations of walleye and northern pike. The lake averages 20 feet deep with a maximum depth around 40 feet, and the bottom is heavy with vegetation — cabbage weeds, coontail, and lily pads dominate the structure. That weed growth makes it a different kind of fishery than the deeper, cleaner lakes nearby. You are not casting to rock structure or suspended fish; you are working the edges and holes in the vegetation, and the fish respond to that environment.

Walleye here run smaller on average than in clearer lakes — most fish in the 15- to 20-inch range, with keepers in the 18- to 22-inch zone. Pike are more abundant and often larger, and they thrive in the weedy cover. The lake is also home to largemouth bass and panfish, though most anglers target the walleye and pike. Because the lake is shallow and weedy, it warms quickly in spring and can be productive from May through October, with a strong bite in early summer and again in fall.

Key Takeaways

  • Lake Thompson is a shallow, weedy 1,100-acre lake best fished from May through October, with peak walleye and pike activity in early summer and fall.
  • Work the weed edges, holes, and transitions rather than open water — the vegetation is the structure that holds fish.
  • Walleye average 15 to 20 inches; pike are more abundant and often larger, making this lake better for pike hunters than trophy walleye seekers.
  • Public boat access is available at the Thompson Lake public landing on the north shore, and the lake has several resorts and rental options nearby.
  • Early morning and evening are most productive, especially in summer when midday weed growth and heat slow the bite.

How to fish the weed structure

The weed beds on Lake Thompson are not obstacles — they are the fishery. Walleye and pike both use the vegetation as cover and hunting ground, and your success depends on working the edges and openings rather than casting into the thick stuff. The most productive approach is to motor slowly along the weed line, casting parallel to the edge or into small holes and pockets within the weeds. A 1/4-ounce jig tipped with a live minnow or soft plastic works well for walleye; pike respond to larger presentations like 3- to 4-inch soft plastics or small crankbaits.

Early morning and evening are prime times, especially in summer. During the heat of the day, the weeds thicken and the fish move deeper or into the thickest cover. If you are fishing midday, focus on the deepest holes you can find — the 35- to 40-foot zones — and work them slowly. Spring and fall offer more consistent all-day fishing because the water is cooler and the weeds have not yet filled in (spring) or have begun to die back (fall).

Trolling can also be effective on Lake Thompson, particularly for walleye. A slow troll along the weed edges with a crankbait or live-bait rig will cover water and locate active fish. Many anglers also use a slip-sinker rig with a live minnow, drifting along the weed line and letting the current or a slow motor push them through productive zones.

Seasonal patterns and timing

Spring (May through early June) is when Lake Thompson wakes up. The water is still cool, the weeds are not yet fully grown, and walleye move shallow to feed. Focus on the 8- to 15-foot zone along the weed edges and in the holes. Early morning is best, and live minnows or small jigs produce consistently. Pike are also active and aggressive in spring, and they will chase larger presentations.

Summer (late June through August) brings the strongest weed growth and the warmest water. The bite is still good in early morning and evening, but midday fishing is slow. If you are on the lake during the day, fish deep or focus on the thickest weed cover where walleye retreat from the heat. Pike, being more aggressive, will still hunt in shallower weeds even in heat, but they too slow down in the afternoon.

Fall (September and October) is excellent. The water cools, the weeds begin to thin, and walleye move back into shallower zones to feed heavily before winter. The bite is consistent throughout the day, and you can cover more water because the weed structure is less dense. This is the best time for anglers who want a more straightforward, less technical bite.

Public access and where to launch

Lake Thompson has a public boat landing on the north shore, operated by the Wisconsin Department of Natural Resources. The Thompson Lake public access site includes a paved ramp, parking for vehicles with trailers, and a courtesy dock. It is the main entry point for most anglers and is well-maintained. From Rhinelander, take Highway 8 south and follow the signs to the landing — it is clearly marked and easy to find.

Several resorts and rental operations are located on or near Lake Thompson, offering cabins, boat rentals, and guide services. If you do not have your own boat, renting is straightforward and affordable. Many resorts also have docks and can point you toward current hot spots or recent catch reports.

Tackle and technique for Lake Thompson walleye

Walleye on Lake Thompson respond well to live-bait presentations and small jigs. A 1/4-ounce jig in white, chartreuse, or natural colors, tipped with a live minnow (fathead or shiner, 2 to 3 inches), is a reliable choice. Cast along the weed edges and work the jig with a slow, subtle lift-and-drop motion. Patience is key — let the jig sit in the holes and let the minnow do the work.

Soft plastics also work, particularly 3- to 4-inch paddle-tail swimbaits or curly-tail grubs in natural colors. Fish them on a 1/4- to 3/8-ounce jig head and use the same edge-and-hole approach. A slip-sinker rig with a live minnow is another solid option, especially if you are drifting or trolling. Use a 1/0 to 2/0 hook and keep the sinker light enough that you can feel the bottom and the weeds without getting snagged constantly.

For pike, upsize everything. Use 3- to 4-inch soft plastics on 3/8- to 1/2-ounce jig heads, or cast small crankbaits (2 to 3 inches) along the weed edges. Pike are not subtle — they will hit a moving lure aggressively, so do not be afraid to work the bait with more energy than you would for walleye. Spinnerbaits and buzzbaits can also be effective, especially in the early morning when pike are hunting in shallow weeds.

What to expect in terms of catch and regulations

Lake Thompson is not a trophy lake, but it is a solid producer for numbers and keeper-size fish. Most walleye caught are in the 15- to 20-inch range, with a good number of 18- to 22-inch keepers. Pike are more abundant and often larger — 24- to 30-inch fish are not uncommon, and the lake holds some larger specimens. Largemouth bass and panfish (bluegill, crappie) are also present and can provide good action if you want a break from targeting walleye and pike.

Wisconsin's current walleye regulations allow a daily limit of five fish with a 15-inch minimum size. Pike have a daily limit of three fish with a 24-inch minimum. These regulations can change, so check the current Wisconsin DNR fishing guide before you go. The lake is open year-round, but winter access requires ice fishing, and the ice season is typically December through March depending on weather.

Nearby water and alternative options

If Lake Thompson is not producing or you want to explore other options, several lakes within 20 minutes of Rhinelander offer different fisheries. Boom Lake, just north of Thompson, is deeper and cleaner, with a different walleye population and better structure for suspended fish. Pelican Lake, also nearby, is larger and offers both walleye and pike in a less weedy environment. Crescent Lake, to the east, is another solid option for walleye and pike.

The Wisconsin River system, which runs through Rhinelander, also holds walleye and pike and offers a different kind of fishing — current-driven structure and a more dynamic environment than a lake. If you are spending time in the Rhinelander area, having a backup plan for a second lake or a river section can make your trip more flexible and productive.

Frequently Asked Questions

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

Early morning (sunrise to mid-morning) and evening (late afternoon through sunset) are most productive, especially in summer when the weeds are thick and the water is warm. In spring and fall, the bite is more consistent throughout the day because the water is cooler and the weed structure is less dense.

Do I need a guide to fish Lake Thompson successfully?

No, but a guide can accelerate your learning curve, especially if you are unfamiliar with weedy lakes. Many resorts on Lake Thompson offer guide services, and a half-day trip can teach you the weed structure and productive zones. If you prefer to fish on your own, start by working the weed edges on the north and east shores, where the public landing is located.

Can I catch pike on Lake Thompson?

Yes, pike are abundant and often larger than walleye. They are more aggressive and easier to catch for anglers new to the lake. Use larger presentations (3- to 4-inch soft plastics or small crankbaits) and work the weed edges with more energy than you would for walleye.

What should I do if I get snagged on weeds?

Snagging is part of fishing a weedy lake. Use a weed guard on your jig or soft plastic to reduce snags, and keep your drag set so that you can break free without losing the entire rig. If you do get stuck, try backing up slowly or shaking the rod tip to work the lure free. Carry extra jigs and soft plastics — you will lose some.

Is Lake Thompson good for a family fishing trip?

Yes. The lake has panfish and largemouth bass in addition to walleye and pike, so younger or less experienced anglers can catch fish on simple presentations. The resorts nearby offer rentals and accommodations, and the public landing is easy to use. The shallow, weedy environment also means you can fish in a smaller boat or even from shore in some areas.
