What You'll Find at Turtle-Flambeau Flowage

Turtle-Flambeau Flowage is a 23,000-acre impoundment in Vilas County that holds some of the most consistent walleye fishing in Wisconsin. The flowage sits where the Flambeau River was dammed, creating a sprawling system of deep basins, shallow bays, and rocky structure that walleye and northern pike use year-round. Unlike some flowages that are either deep or shallow, Turtle-Flambeau gives you both—and that's what makes it work so well.

The water is relatively clear, which matters for how you fish it. Walleye here respond to live bait and crankbaits in the traditional way, but they also see your lure clearly, so presentation counts. Pike run large and aggressive, and they're abundant enough that you'll encounter them whether you're targeting them or not. The flowage also holds decent numbers of largemouth bass and panfish, though most anglers come for the walleye.

Key Takeaways

  • Turtle-Flambeau Flowage holds walleye year-round in distinct depth zones—shallow structure in spring and fall, deeper basins in summer.
  • The flowage has two main access points: the Turtle Flambeau Scenic Waters Area on the north end and boat landings on the south end near Mercer.
  • Live bait (shiners and crawlers) and crankbaits work well in spring and fall; summer walleye move deeper and respond better to jigging and live bait on bottom.
  • Pike are plentiful and aggressive; use larger lures and steel leaders if you want to avoid losing tackle to toothy strikes.
  • The flowage is large enough that finding fish requires understanding structure—points, drop-offs, and weed edges hold walleye consistently.

Spring Walleye Fishing (April Through May)

Spring is when Turtle-Flambeau walleye move shallow to spawn and feed aggressively. The fish move into bays and along shorelines with rock and wood, and they'll hit crankbaits and live bait presentations hard. Focus on the north end of the flowage, where the Turtle River arm feeds in—that current break attracts walleye moving upstream.

Shallow-running crankbaits in the 5- to 8-foot range work well in early spring when water temps are still cold. As the season progresses and water warms into the 50s, walleye move slightly deeper but stay accessible. Live shiners under a bobber or on a simple jig-and-minnow rig will catch fish consistently. The key is covering water along structure—points, weed edges, and rocky banks. Walleye in spring are less finicky than they'll be in summer, so don't overthink it.

Summer Fishing and the Deep-Water Challenge

By mid-June, Turtle-Flambeau walleye have moved into deeper basins—typically 25 to 40 feet—where they sit on structure and feed during low-light periods. Summer is harder fishing than spring, but it's not impossible. The key is finding the right depth zones and timing your fishing for early morning, evening, and night.

Jigging with live crawlers or shiners is the most effective summer technique. Drop your jig to the bottom in the deeper basins and work it slowly, feeling for the slight tap of a walleye. The Turtle Flambeau Scenic Waters Area on the north end has some of the deepest, most consistent structure, and it's worth exploring if you have a good sonar unit. Pike will also be in these deeper zones, so expect to see them. If you want to fish during midday, focus on the deepest holes and the shadiest structure you can find—under downed trees or in the thickest weed growth.

Fall Fishing and the Second Peak

Fall (September through October) brings a second strong bite as walleye move shallow again to feed before winter. The pattern mirrors spring—shallow structure, aggressive feeding, and good response to crankbaits and live bait. Water temperatures in the 50s and 60s put walleye in a feeding mood, and they'll stay active longer into the day than they do in summer.

The south end of the flowage, near Mercer, has good shallow bays and weed edges that hold walleye in fall. Work the same presentations you used in spring: shallow crankbaits, jig-and-minnow combos, and live bait under bobbers. Fall fishing can last well into November if the weather stays mild, making it one of the best times to visit if you want consistent action.

Where to Launch and How to Navigate

The Turtle Flambeau Scenic Waters Area, managed by the Wisconsin Department of Natural Resources, sits on the north end of the flowage and offers a public boat landing, parking, and facilities. This is the most developed access point and a good starting location if you're unfamiliar with the flowage. The scenic waters designation means the north end is quieter and less developed than the south end, which appeals to anglers who want a more remote experience.

The south end has several boat landings near Mercer, including the Mercer Public Landing and private launch facilities. The south end is more developed and sees more traffic, but it gives you quick access to the shallower bays and weed edges that hold walleye in spring and fall. If you're fishing summer, the deeper basins in the middle and north end are worth the longer run from either launch.

The flowage is large enough that you need a map or GPS to navigate efficiently. Walleye structure is scattered across 23,000 acres, and random cruising will waste fuel and time. A detailed contour map or a GPS unit loaded with bathymetry will help you find drop-offs, points, and basins quickly.

Pike and What to Expect

Northern pike are abundant at Turtle-Flambeau and will strike your walleye lures regularly. Pike here run 24 to 36 inches on average, with occasional fish pushing 40 inches. They're aggressive and will hit crankbaits, spinners, and live bait presentations meant for walleye. If you're not targeting pike, use a steel leader to avoid losing tackle to their teeth.

If you want to fish for pike specifically, use larger lures—6- to 8-inch crankbaits, large spinners, and bigger live bait (6- to 8-inch shiners). Pike respond well to fast retrieves and erratic presentations. The weed edges and shallow bays in spring and fall hold pike, and they'll also be in the deeper structure during summer. Pike fishing at Turtle-Flambeau is often incidental, but it's consistent enough that you should be prepared for it.

Regulations and Seasonal Considerations

Wisconsin's walleye season on Turtle-Flambeau runs year-round, with a daily bag limit of five walleye. Pike season also runs year-round with a daily bag limit of five. Check the current Wisconsin fishing regulations before you go, as rules can change. The flowage is open to public fishing, and a Wisconsin fishing license is required.

Winter fishing is possible on Turtle-Flambeau, though it requires ice-fishing gear and knowledge of safe ice conditions. The flowage typically freezes solid by December, and walleye can be caught through the ice in the deeper basins. If you're planning a winter trip, contact the Mercer area chamber of commerce or a local bait shop for current ice conditions and recommendations.

Frequently Asked Questions

What's the best time of year to fish Turtle-Flambeau?

Spring (April–May) and fall (September–October) are the most productive times. Walleye are shallow, aggressive, and easier to locate. Summer fishing is possible but requires deeper presentations and more patience. Winter ice fishing is an option if you have the right gear and ice conditions are safe.

Do I need a guide to fish Turtle-Flambeau successfully?

No, but a guide can save time if you're unfamiliar with the flowage. The structure is scattered across 23,000 acres, and a good map or GPS unit with bathymetry will help you find walleye on your own. Local bait shops near Mercer can also point you toward current hot spots.

Can I catch pike at Turtle-Flambeau, or is it only walleye?

Pike are abundant and aggressive. You'll encounter them while walleye fishing, and they're large enough to be worth targeting. Use a steel leader if you don't want to lose lures to their teeth, and expect pike to hit your walleye presentations regularly.

What kind of boat do I need?

Any boat that can safely handle a 23,000-acre flowage will work. A 16- to 20-foot boat with a sonar unit is ideal for finding structure and deeper basins, but smaller boats work fine if you stick to the shallower bays and launch from the north end. The flowage can get rough in wind, so check the forecast before heading out.

Where should I stay if I'm visiting Turtle-Flambeau?

Mercer, Wisconsin, is the closest town and has lodging, restaurants, and bait shops. The town sits about 10 minutes from the south-end boat landings. The north end (Turtle Flambeau Scenic Waters Area) is more remote but offers a quieter experience and is worth the drive if you want fewer people on the water.
