What You'll Find at South Twin Lake

South Twin Lake is a shallow, weedy walleye and pike lake in Vilas County that rewards anglers who understand structure and timing. The lake runs roughly 800 acres and averages 20 to 25 feet deep, with extensive weed beds, a soft bottom, and scattered rock piles that hold fish. Walleye are the primary target here—they're abundant and willing—but the pike population is strong enough that you'll hook them regularly, especially in spring and fall.

The character of South Twin is different from the deep, clear lakes Vilas is also known for. This is a lake where you're reading vegetation, working shallow structure, and often fishing in water you can see into. That makes it excellent for anglers who want to understand what's happening beneath the surface and less ideal for those who prefer deep-water jigging or trolling open water.

Key Takeaways

  • South Twin holds abundant walleye in shallow water and weed beds, with pike as a regular secondary target.
  • Spring and fall are peak seasons; summer requires early morning and evening fishing because midday heat pushes fish deep into weeds.
  • Soft bottom and extensive vegetation mean live bait (shiners, crawlers) often outperforms artificials, though jigs and crankbaits work the weed edges.
  • Public boat access is available at the South Twin Lake public landing on the south shore; the lake has no size restrictions on motors.
  • Walleye season runs year-round in Vilas County, but ice-out through May and September through freeze-up are the most productive periods.

Spring and Fall: The Prime Seasons

Spring fishing—from ice-out through May—is when South Twin produces its best action. Walleye move shallow to spawn and feed aggressively in the warming water. Fish the weed edges in 6 to 12 feet of water, and work live shiners on simple slip-sinker rigs or jig-and-minnow combinations. Early morning and late evening are most productive, but spring's longer daylight means you can fish effectively from dawn until well after sunrise.

Fall mirrors spring in many ways. September through freeze-up, walleye move shallow again as water cools, and pike become more aggressive. The weed beds thin as vegetation dies back, which actually makes fish easier to locate—they concentrate along the remaining green edges. This is also when you'll see the most consistent pike action; throw larger baits and expect hookups in the 24- to 30-inch range.

Summer Fishing: Early and Late

Summer on South Twin requires a shift in strategy. Midday heat pushes walleye deep into the densest weed beds or to the few deeper holes the lake offers. Fishing from 10 a.m. to 4 p.m. is often slow and frustrating. Instead, focus on the first two hours after sunrise and the last two hours before sunset, when walleye move into shallower water to feed.

Early morning, work the weed edges in 8 to 15 feet with live bait or small jigs. As the sun climbs, follow the fish deeper into the vegetation. If you're willing to fish the middle of the day, target the thickest weed beds with a weedless jig or a soft plastic rigged to slip through vegetation without snagging. It's technical fishing, but it works when everything else is slow.

Winter and Ice Fishing

South Twin is a solid ice-fishing lake, though the shallow depth and soft bottom mean you need to find the right spots. Walleye congregate around the deeper holes and along the edges of the weed beds, which remain visible under the ice. Tip-ups with live shiners work well, as do small jigging spoons tipped with minnow heads.

The lake typically freezes by mid-December and remains fishable through March, depending on snow cover and weather. Check current ice conditions before heading out—the Vilas County Sheriff's Department maintains ice-thickness reports during winter. Bring a good auger and a depth finder; the soft bottom can be deceptive, and you may drill through 18 inches of ice only to find 4 feet of water where you expected 12.

Tackle and Bait That Works

Live bait is your most reliable option on South Twin. Shiners in the 3- to 4-inch range work year-round for walleye; crawlers are excellent in spring and fall. Pike will take both, but they also respond well to larger shiners (5 to 6 inches) and small suckers. A simple slip-sinker rig with a live bait hook and a 12-inch leader is all you need for drifting or anchoring.

If you prefer artificials, jigs in the 1/8- to 1/4-ounce range tipped with minnows or soft plastics work the weed edges effectively. Crankbaits that dive to 8 to 12 feet are useful for covering water along the weed lines. Spinnerbaits and buzzbaits can produce pike in shallow water, especially in spring. The key is working structure deliberately rather than casting randomly—this lake rewards precision.

Public Access and Facilities

The South Twin Lake public boat landing is located on the south shore and offers a paved ramp, parking for trailers, and a small pier. The landing is maintained by Vilas County and is open year-round. There are no size restrictions on boat motors, so you can run a full-power rig if you choose, though the shallow water and vegetation mean a smaller, more maneuverable boat is often more practical.

The nearest services—fuel, bait, and lodging—are in Eagle River, about 15 minutes away. Several resorts and rental cabins dot the Vilas County area, and many cater specifically to anglers. If you're planning a multi-day trip, book lodging in advance during peak seasons (May and September).

Understanding the Regulations

Walleye season in Vilas County runs year-round with a daily bag limit of five fish and a 15-inch minimum size. Pike season also runs year-round with a daily bag limit of three fish and a 24-inch minimum size. These regulations are current as of this writing, but Wisconsin Department of Natural Resources rules can change; check the current Wisconsin fishing guide before you go.

The lake is open to public fishing, and no special permits are required beyond a valid Wisconsin fishing license. If you're from out of state, you can purchase a short-term license (three-day or annual) through the Wisconsin DNR website or at most bait shops in the area.

Frequently Asked Questions

Is South Twin Lake good for beginners?

Yes, if you're comfortable with live bait and simple rigs. The walleye are abundant and not particularly selective, and the shallow water means you can see structure and understand what's happening. The main challenge is the vegetation—you'll lose some tackle to weeds—but that's part of learning a shallow lake.

What's the difference between South Twin and North Twin?

North Twin is deeper, clearer, and more structured with rock. South Twin is shallower, weedier, and softer-bottomed. North Twin suits deep-water jigging and trolling; South Twin suits shallow-water live bait and weed-edge fishing. Both hold walleye, but they fish very differently.

Can I fish South Twin in summer, or is it too warm?

You can fish it, but you have to adjust your timing and location. Fish early morning and evening, and focus on the weed beds and deeper holes during the day. Summer is the slowest season, but it's not impossible—it just requires more effort and patience.

Do I need a guide to fish South Twin Lake?

No, but a guide can accelerate your learning curve, especially if you've never fished a shallow, weedy lake before. Many Vilas County guides specialize in walleye and know South Twin well. If you're confident reading a map and using a depth finder, you can figure it out on your own.

What should I do if I get snagged in the weeds?

Reverse slowly and try to back out the way you came in. If that doesn't work, cut your line and retie—fighting a snag often breaks your rod or damages the boat. Bring extra tackle and accept that weed fishing means losing some gear. It's the cost of fishing shallow, productive water.
