What Lake Mohawksin offers anglers

Lake Mohawksin is a shallow, weedy impoundment near Tomahawk that holds walleye, northern pike, and largemouth bass in water that rarely exceeds 20 feet deep. The lake's character is defined by its vegetation—cattail marshes, lily pads, and submerged cabbage beds create ideal habitat for pike and bass but also make navigation and casting a puzzle you have to solve each season. Walleye fishing here is best in spring and fall when cooler water pushes them into slightly deeper holes and along weed edges; summer heat drives them into the deepest basins or into the marsh channels where current moves water.

The lake covers roughly 1,200 acres and sits in the heart of Wisconsin's lake country, close enough to Tomahawk for a day trip but far enough from major highways that it doesn't draw the weekend crowds you'll find on better-known Chain O'Lakes water. That solitude is part of its appeal. The trade-off is that you need to put in the work to understand where fish hold in a lake where structure is mostly vegetation rather than rock or hard bottom.

Key Takeaways

  • Lake Mohawksin is a shallow, weedy lake best suited to walleye and pike anglers who are comfortable working vegetation and adjusting to seasonal patterns.
  • Spring and fall walleye fishing focuses on weed edges and the deeper holes along the main basin; summer requires moving into marsh channels or the deepest water available.
  • Pike fishing is productive year-round in the shallows, especially around cattail edges and lily pad fields where they hunt smaller fish.
  • A Wisconsin fishing license and a trout stamp (if you plan to fish any of the nearby spring-fed streams) are required; no special lake permit is needed.
  • Public boat access is available at the Mohawksin Landing on the north shore; plan to arrive early on weekends, as the lot fills quickly during summer.

Spring walleye patterns on shallow water

Spring is when Lake Mohawksin rewards anglers who understand how walleye move in shallow lakes. As water temperatures climb from the low 40s into the 50s, walleye move out of the deepest basins and begin feeding along weed edges and in the marsh channels that connect different parts of the lake. The key is finding the transition zone where deep water meets shallow vegetation—typically 8 to 14 feet deep along the outer edge of a weed bed.

Jigging is the most effective spring technique here. Use a 1/4-ounce to 3/8-ounce jig tipped with a live minnow or a soft plastic, and work the weed edges slowly. The marsh channels that run through the middle of the lake are particularly productive in late April and May; walleye stack in these narrow corridors because they concentrate baitfish. Casting parallel to the channel edge rather than across it keeps you in the strike zone longer and reduces snags on submerged vegetation.

Trolling crankbaits along the deeper weed edges also works, especially early in the morning or late in the evening. Stick to baits that dive to 6 to 10 feet and can handle occasional contact with weeds. The water clarity on Mohawksin is moderate—typically 4 to 6 feet—so natural colors like perch and crawdad patterns outperform bright or flashy options.

Summer fishing in the heat and weeds

Summer on Lake Mohawksin is a different puzzle. Walleye retreat from the shallow weed edges into the deepest holes and into the marsh channels where water temperature stays cooler and oxygen levels remain stable. The lake's maximum depth is around 22 feet, and that's where you'll find the most consistent summer walleye action. Vertical jigging over these deep holes with live bait or soft plastics is more effective than casting.

Pike, by contrast, remain active in the shallows throughout summer. The extensive lily pad fields and cattail marshes provide cover and hunting grounds for pike that can reach 35 inches or better. Early morning and late evening are prime times; during midday heat, pike move deeper into the marsh or into the shade of dense vegetation. Casting large topwater plugs or soft plastics around pad edges can produce explosive strikes, though you'll lose some fish to the thick weeds—accept that as part of fishing this lake.

If you're targeting walleye in summer, plan to fish the deepest basin on the south end of the lake or focus on the marsh channels during low-light periods. Night fishing can be productive; many anglers fish the channels after dark with live bait rigs or slow-moving soft plastics. Bring a headlamp and watch for submerged logs and stumps that create snags in the dark.

Fall patterns and the transition back to shallow water

Fall is arguably the best season on Lake Mohawksin. As water temperatures drop from the 70s into the 50s, walleye move back into the shallower weed edges and become more aggressive. The weed beds begin to thin in late September and October, which actually makes fishing easier—you have clearer sight lines and fewer snags. Walleye feed heavily in preparation for winter, and they're less selective about lure choice and presentation.

Casting and jigging along the weed edges is highly productive in fall. Use slightly heavier jigs (3/8 to 1/2 ounce) because the water is cooler and walleye are more willing to chase. Soft plastics in natural colors—grays, blacks, and browns—work well. The marsh channels remain productive, but the outer weed edges and the transition zones between shallow and deep water are where you'll find the most consistent action.

Pike fishing in fall is also excellent. The cooler water makes them more active throughout the day, not just at dawn and dusk. Casting larger baits and lures around the remaining vegetation can produce consistent catches. Many anglers target pike in fall because the fish are in prime condition and the fishing pressure is lower than in summer.

Winter access and ice fishing

Lake Mohawksin freezes reliably by mid-December, and ice fishing for walleye and pike is a winter option for anglers comfortable on the ice. The shallow nature of the lake means ice-out can be unpredictable—some years the ice is safe by early April, other years it lingers into late April. Check current conditions with the Tomahawk area bait and tackle shops before heading out.

Walleye ice fishing focuses on the deeper holes and the marsh channels. Tip-ups with live minnows are effective, as are jigging presentations with small spoons or soft plastics. Pike can be caught through the ice as well, though they're less predictable than walleye. The shallow water means you don't need to drill as deep as you would on some Wisconsin lakes, but you do need to be patient—ice fishing on Mohawksin is slower than on deeper, clearer lakes.

Boat access and practical information

Public boat access to Lake Mohawksin is available at Mohawksin Landing on the north shore. The landing has a paved ramp, parking for roughly 30 vehicles, and a small pier. The lot fills quickly on summer weekends and holidays, so arrive early if you're planning a weekend trip. There is no launch fee, but the lot is maintained by the town and can close during maintenance or extreme weather.

The lake has no speed restrictions, so you'll encounter faster boats and jet skis, particularly on weekends. If you prefer quieter water, fish early in the morning or on weekdays. Several resorts and rental cabins border the lake, and a few offer boat rentals if you don't have your own. The nearest full-service bait and tackle shop is in Tomahawk, about 10 minutes away by car.

A Wisconsin fishing license is required for all anglers 16 and older. No special lake permit is needed. If you plan to fish any of the nearby spring-fed streams that feed into the lake system, you'll need a trout stamp in addition to your base license. Licenses are available online through the Wisconsin Department of Natural Resources website or at any bait shop in the area.

Frequently Asked Questions

What's the best time of year to fish Lake Mohawksin?

Spring (April through May) and fall (September through October) are the most productive seasons for walleye. Summer is better for pike and for anglers willing to fish deeper water or night hours. Winter ice fishing is possible but slower than other seasons.

Do I need a boat to fish Lake Mohawksin?

A boat is helpful but not required. Shore fishing is possible along parts of the north and east shorelines, though access is limited by private property and marsh vegetation. Most anglers use a boat to reach the productive deeper holes and weed edges.

What size pike and walleye can I expect to catch?

Walleye typically range from 12 to 18 inches, with occasional fish to 22 inches. Pike are more variable; 24 to 28 inches is common, and fish over 30 inches are caught regularly. The shallow, weedy habitat produces pike more consistently than trophy walleye.

Is the water clear enough to see fish?

Water clarity on Mohawksin is moderate, usually 4 to 6 feet. That's clear enough to see fish in shallow water on sunny days, but not clear enough to sight-fish consistently. Use natural-colored lures rather than bright or flashy options.

Can I fish Lake Mohawksin if I'm new to Wisconsin fishing?

Yes, but the lake rewards anglers who take time to learn its weed structure and seasonal patterns. If you're new to the area, consider hiring a local guide for a half day to learn the lake's layout and productive zones. The effort pays off in better fishing for years to come.
