What Island Lake offers and who should fish it

Island Lake is a shallow, weedy 1,100-acre lake in Vilas County in northeastern Wisconsin, roughly 30 minutes south of Eagle River. The lake holds walleye, northern pike, and largemouth bass, with walleye as the primary draw. The water is stained to dark, depths rarely exceed 30 feet, and the lake is choked with aquatic vegetation — lily pads, coontail, and cabbage beds dominate the structure. This is not a lake for open-water trolling or sight-casting to clear-water structure. It rewards anglers who work shallow cover methodically, understand weed-edge transitions, and fish early morning or late evening when walleye move into the shallows to feed.

Island Lake is best suited to anglers with experience in weedy systems and comfort working around dense vegetation. Beginners or anglers expecting clear water and deep structure will find it frustrating. The lake's shallow profile and heavy weed growth mean that summer fishing is most productive in the first two hours after sunrise and the last two hours before sunset, when walleye leave the deep weed sanctuaries and hunt in shallower transition zones.

Key Takeaways

  • Island Lake holds walleye, pike, and bass in shallow, heavily weeded water where vegetation is the primary structure.
  • Early morning and late evening are the most productive times, especially in summer, because walleye feed in shallow water during low-light periods.
  • Soft plastics, live bait rigged on jig heads, and shallow-running crankbaits work better than deep-diving lures in this system.
  • Wisconsin requires a fishing license and inland trout stamp (if you plan to fish trout waters); walleye and pike have no special endorsement but are subject to daily bag limits and size restrictions.
  • Public boat access is available at the Island Lake public landing on the north shore; several resorts and rental properties offer lodging and boat rentals nearby.

Seasons and water conditions

Island Lake's fishing calendar is shaped by its shallow profile and heavy vegetation. Spring (April through May) is productive as walleye move into shallow water to spawn and feed. Water temperatures in the 45–55°F range trigger feeding activity, and anglers can find fish in 4–10 feet of water along weed edges and in bays. Jigs tipped with live minnows or soft plastics work well during this period.

Summer (June through August) is the most challenging season. Walleye retreat into deeper weed beds and the darkest water during daylight hours. Early morning (first two hours after sunrise) and late evening (last two hours before sunset) are the only reliable windows. Night fishing under lights can be productive for pike and bass. Water temperatures climb into the 70s, and the weed growth becomes dense enough to make navigation difficult without a detailed map.

Fall (September through October) is excellent. Walleye move back into shallower water as water temperatures drop, and they feed more actively throughout the day. Weed edges, shallow bays, and transition zones between shallow and deeper water hold fish. This is often the most consistent time to fish Island Lake.

Winter (November through March) is closed to fishing under Wisconsin regulations for most species, though some anglers pursue pike through the ice in late winter. Check current Wisconsin Department of Natural Resources (WDNR) regulations before planning an ice-fishing trip.

Species, regulations, and daily limits

Island Lake's primary species is walleye. The lake is managed under Wisconsin's statewide walleye regulations: a daily bag limit of 5 fish, with a 15-inch minimum size. Walleye under 15 inches must be released. The lake does not have special slot limits or reduced bag limits, so standard statewide rules apply.

Northern pike are abundant and often incidental catches while targeting walleye. Wisconsin's pike regulations allow a daily bag limit of 1 fish with a 24-inch minimum size. Pike under 24 inches must be released. Pike in Island Lake tend to run smaller than in some other northern Wisconsin lakes, so the 24-inch minimum is a meaningful restriction.

Largemouth bass are present but not the primary target. Wisconsin's bass regulations allow a daily bag limit of 5 fish with a 12-inch minimum size. Bass under 12 inches must be released.

All anglers must carry a valid Wisconsin fishing license. No special endorsements are required for walleye or pike, but you must follow the daily bag limits and size restrictions listed above. Regulations change periodically, so check the WDNR website or the current Wisconsin fishing regulations pamphlet before your trip.

Access and boat launch information

Island Lake has one public boat landing: the Island Lake Public Access on the north shore, managed by Vilas County. The landing has a paved ramp, parking for roughly 20 vehicles with trailers, and a courtesy dock. The ramp is well-maintained and suitable for most trailers, though the parking lot can fill on summer weekends. There is no fee to launch.

Several resorts and private rental properties on Island Lake offer boat rentals, lodging, and guide services. The nearest town with services is Eagle River, about 30 minutes north, which has gas stations, restaurants, and tackle shops. Vilas County also manages several public campgrounds within 15 minutes of the lake, including Anvil Lake and Crescent Lake campgrounds, both of which offer water access and basic amenities.

The lake is accessible year-round by vehicle, though winter road conditions in northern Wisconsin can be severe. Summer is the most reliable season for access. If you are planning a fall or spring trip, check road conditions and weather forecasts before departing.

Tactics and lure selection for shallow, weedy water

Island Lake's shallow, vegetation-heavy structure demands a different approach than clear-water lakes. Jigs and soft plastics are the most effective lures. A 1/8-ounce to 1/4-ounce jig head tipped with a 2–3 inch soft plastic (paddle-tail or shad-shaped) allows you to work weed edges, drop into pockets, and maintain contact with the bottom. Fish these along the outside edge of weed beds, in channels between vegetation, and in shallow bays during low-light hours.

Live bait rigs are equally productive. A simple jig head with a live minnow (2–3 inches) or leech works well in spring and fall when walleye are more aggressive. Drift these along weed edges or cast to visible structure. In summer, live bait fished at dawn and dusk is often more effective than artificials.

Shallow-running crankbaits (diving to 4–8 feet) can work along weed edges, but they foul easily in dense vegetation. Use them in open pockets or along the outside edge of weed beds rather than trying to fish through thick cover.

Avoid deep-diving lures, trolling, and open-water presentations. Island Lake rewards patience and precision in shallow cover. Slow your retrieve, make accurate casts to specific targets, and expect to lose lures to vegetation — it is part of fishing this system.

Nearby lodging and services

Eagle River, the nearest town, is about 30 minutes north of Island Lake and offers the most reliable selection of lodging, restaurants, and tackle shops. The Eagle River area is a hub for northern Wisconsin tourism and has motels, vacation rentals, and resorts ranging from budget to upscale. Several tackle shops in Eagle River stock walleye and pike lures, live bait, and local knowledge.

On or near Island Lake itself, several small resorts and cabin rental properties offer direct water access and boat rentals. These tend to be family-oriented and book up quickly during summer and fall weekends. Vilas County public campgrounds (Anvil Lake, Crescent Lake, and others) offer affordable camping with basic amenities and are within 15 minutes of Island Lake's public landing.

Gas, groceries, and general supplies are available in Eagle River. If you are planning a multi-day trip, stock up before heading to the lake, as services on the water are limited.

Frequently Asked Questions

Can I fish Island Lake in summer, or is it only good in spring and fall?

You can fish in summer, but success requires fishing early morning (first two hours after sunrise) or late evening (last two hours before sunset). Walleye retreat into deep weed beds during the day when water temperatures are warm. Night fishing under lights can also be productive. Midday fishing in summer is rarely worthwhile.

What is the best way to navigate the weeds without getting stuck?

Use a detailed lake map (available from the WDNR or tackle shops in Eagle River) to identify channels, deeper pockets, and weed-edge transitions. A GPS unit or smartphone app with lake mapping helps. Move slowly, watch your depth finder, and learn to recognize the difference between shallow weeds and deeper water. Many local guides know the best routes and can save you time and frustration.

Do I need a guide to fish Island Lake successfully?

A guide is not required, but the lake rewards local knowledge. Guides know the best weed edges, seasonal patterns, and low-light feeding zones. If you are new to weedy systems or unfamiliar with the lake, a half-day guide trip can accelerate your learning curve. Several resorts on Island Lake offer guide services.

What size boat do I need?

A 16–18 foot boat with a shallow-draft hull works well. Avoid large, deep-draft boats that draw more than 2 feet of water, as you will run aground in many areas. A trolling motor is useful for precise positioning along weed edges. Many rental boats at Island Lake resorts are sized appropriately for the lake's shallow profile.

Is Island Lake good for pike fishing?

Yes, pike are abundant, but they tend to run smaller than in some other northern Wisconsin lakes. Pike under 24 inches are common, and the 24-inch minimum size limit means many pike must be released. Pike fishing is often incidental to walleye fishing, but targeting pike with larger lures and live bait can produce results, especially in spring and fall.
