What You'll Find at South Twin Lake

South Twin Lake is a shallow, 181-acre impoundment in Vilas County in far northern Wisconsin, roughly 15 miles south of Eagle River. The lake sits at about 1,600 feet elevation and holds a mix of walleye, northern pike, and panfish in a basin choked with aquatic vegetation — lily pads, coontail, and wild rice beds dominate the structure. The water clarity is moderate to stained, and depths rarely exceed 20 feet, with most of the productive water between 8 and 15 feet.

This is a lake built for shallow-water techniques and for anglers who don't mind working through weeds. The shoreline is largely undeveloped, with public access via a Wisconsin Department of Natural Resources boat landing on the north end. South Twin sits in the heart of Wisconsin's lake country, where dozens of similar basins cluster within an hour's drive, so many anglers fish it as part of a larger trip rather than as a destination unto itself.

Key Takeaways

  • South Twin Lake holds walleye and northern pike in shallow, weedy water between 8 and 15 feet deep, requiring weed-tolerant presentations like jigs and soft plastics.
  • Public boat access is available at the DNR landing on the north shore; the lake is open year-round for both open-water and ice fishing.
  • Walleye fishing peaks in spring (April–May) and fall (September–October), while pike are active throughout the season in the weed edges.
  • Wisconsin fishing regulations apply: a current fishing license is required, and daily bag limits are five walleye and five northern pike per person.
  • The lake is small enough to fish thoroughly in a half day, making it a practical stop on a multi-lake trip through Vilas County.

Seasons and What to Expect

Spring (April through May) is the strongest walleye period. As the ice clears and water temperatures climb into the 40s and low 50s, walleye move into the shallower weed edges to feed before spawning. Jigs tipped with live minnows or soft plastics work well along the weed lines and in the deeper pockets within the vegetation. Early morning and late evening produce the most consistent bites.

Summer (June through August) slows the walleye bite considerably as the fish move deeper and the weed growth becomes dense. Pike, however, remain active in the thicker weed cover, especially in early morning and late evening. Topwater lures and weedless spoons can draw strikes in the densest vegetation. Panfish — bluegill and crappie — remain steady throughout the summer in 6 to 12 feet of water.

Fall (September through October) brings another strong walleye window as water temperatures drop and fish move back into the shallows to feed before winter. The weed beds begin to thin, making presentations easier and bite rates more predictable. Pike also feed aggressively in fall, and both species can be caught on the same presentations.

Winter ice fishing runs from December through March, depending on ice thickness and safety conditions. Walleye and pike are caught through the ice in 10 to 15 feet of water using live minnows under tip-ups or small jigging presentations. Check current ice conditions with the Vilas County Sheriff's Department or a local bait shop before heading out.

Access and Launch Information

The primary public boat access is the Wisconsin DNR landing on the north shore of South Twin Lake, accessible via County Road M. The landing has a paved ramp, parking for roughly 15 vehicles, and vault toilets. No fuel or concessions are available at the landing, so plan accordingly.

The nearest services — gas, food, and lodging — are in Eagle River, about 15 miles north. Several resorts and cabins dot the surrounding lakes, and many offer boat rentals if you don't have your own. The area is well-served by state highways, and the drive from Milwaukee or Madison is roughly four to five hours.

South Twin Lake is open to public fishing year-round. No special permits or reservations are required beyond a valid Wisconsin fishing license. The lake is small enough that a canoe or kayak can be effective if you prefer a quieter approach to the weed edges, though a small motorboat is more practical for covering water and working the deeper basins.

Walleye Fishing Tactics

Walleye in South Twin Lake respond best to presentations that work through or near weed cover. Jigs in the 1/8- to 3/8-ounce range, tipped with live minnows (shiners or chubs) or soft plastics, are the standard approach. Cast along the weed edges, work the deeper pockets within the vegetation, and pause the jig to let it flutter — walleye often strike on the fall.

Crankbaits that reach 6 to 12 feet are effective in spring and fall when the weeds thin slightly. Shallow-running cranks work the edges; deeper-diving models can probe the open basins. Retrieve slowly and be prepared for snags in the vegetation — this is not a lake for light line or finesse equipment.

Live-bait rigs — a slip sinker, swivel, and 18-inch leader with a size 2 or 4 hook — work well if you prefer a stationary approach. Anchor near a weed edge in 8 to 12 feet of water, use a live minnow, and wait. This method is especially productive at dawn and dusk.

Northern Pike and Panfish

Northern pike in South Twin Lake are abundant and aggressive, particularly in the thickest weed cover. Weedless spoons, topwater lures, and soft plastics on weedless jigs all draw strikes. Pike are less time-sensitive than walleye, so you can fish for them throughout the day. Early morning and late evening still produce the most consistent action, but midday bites are common in summer.

Panfish — bluegill, crappie, and pumpkinseed — are present in good numbers and provide a reliable option when walleye and pike are slow. Small jigs (1/16 to 1/8 ounce) tipped with live minnows or wax worms work in 6 to 12 feet of water. A simple bobber-and-minnow setup is equally effective and requires no special technique.

Regulations and Licensing

Wisconsin fishing regulations apply to South Twin Lake. You must have a current Wisconsin fishing license, available online through the Wisconsin DNR website or at any bait and tackle shop. A license is valid for one year from the date of purchase.

Daily bag limits are five walleye and five northern pike per person. Size limits vary: walleye must be at least 15 inches, and northern pike must be at least 24 inches. Panfish have no minimum size and a daily limit of 25 per person. Check the current Wisconsin fishing regulations guide before you fish, as rules can change year to year.

The lake is open to both open-water and ice fishing. No special permits are required beyond the fishing license. Catch-and-release is always an option if you prefer to fish without keeping fish.

Nearby Waters and Multi-Lake Trips

South Twin Lake is one of dozens of fishable lakes within a short drive in Vilas County. North Twin Lake, just north of South Twin, holds similar species and is equally accessible. Crystal Lake, Presque Isle Lake, and Anvil Lake are all within 20 minutes and offer similar shallow, weedy structure with walleye and pike.

Many anglers use South Twin as a morning or afternoon stop on a larger trip, fishing two or three lakes in a single day. The small size of the lake — 181 acres — means you can cover the productive water thoroughly in three to four hours. This makes it practical to fish South Twin early, move to a larger lake for midday, and return to South Twin or a neighboring lake for the evening bite.

Frequently Asked Questions

What's the best time of day to fish South Twin Lake?

Early morning (sunrise to mid-morning) and late evening (two hours before sunset through dark) are most productive for both walleye and pike. Midday fishing is slower but not impossible, especially for pike in heavy weed cover. Summer panfish can bite throughout the day in deeper water.

Do I need a boat, or can I fish from shore?

A boat is practical because the productive water is spread across the lake and weed beds are dense. Shore fishing is possible near the boat landing and along accessible shoreline, but you'll cover far less water and encounter more vegetation. A canoe or kayak is a quieter alternative to a motorboat and works well for working weed edges.

What size boat works best on South Twin Lake?

A 16- to 20-foot boat with a trolling motor is ideal. The shallow water and dense weeds make a large, deep-draft boat impractical. A small aluminum boat or even a canoe is sufficient if you're comfortable navigating the weed beds and don't mind slower travel.

Can I fish South Twin Lake in winter?

Yes, ice fishing is open from December through March, depending on ice thickness. Check ice conditions with the Vilas County Sheriff's Department or a local bait shop before heading out. Walleye and pike are caught through the ice in 10 to 15 feet of water using live minnows and small jigs.

What should I bring that I might not have at home?

Weedless jigs, soft plastics, and spoons are essential — standard open-water lures snag constantly. Bring extra line and be prepared to re-tie often. A landing net helps with pike. Sunscreen and insect repellent are important in summer. In spring and fall, layers and a rain jacket are necessary.
