The Spring Walleye Run Below Petenwell Dam: A Local's Guide for Visiting Anglers
Late February into early March, walleye stage below Petenwell Dam in numbers that draw anglers from across the Midwest. Here is the local knowledge you need to fish it right.
How do you fish the spring walleye run below Petenwell Dam in Wisconsin?
The spring walleye run below Petenwell Dam begins in late February into early March as water temperatures climb into the low-to-mid 40s Fahrenheit. Walleye stage in back current areas and along the concrete dam face structure in 4–16 feet of water. Quarter-ounce jigs with plastics or minnows pitched to the dam face and worked back through current seams is the primary tactic. First light through mid-morning produces the most consistent action. Local guide Fish Bones Guide Service reports 50–60 fish days at the peak of the run, with 8–12 legal-sized walleye a realistic expectation on a strong day.
The spring walleye run below Petenwell Dam is one of those fisheries that locals talk about quietly among themselves and visiting anglers discover with something close to disbelief the first time they experience it. Fifty fish days during the spawn peak are not exceptional — they are normal on a good-conditions day in late February or early March when walleye are stacked in the tailwater. This guide is written from local knowledge — the kind of information that guides and longtime regulars carry and that no generic Wisconsin fishing article will give you. See the full spring fishing season guide for the broader context, and the dam-area property guide for buyers who want proximity to this fishery.
Timing the Run — When to Show Up
Water Temperature Is the Trigger
Walleye move below the Petenwell Dam to spawn when water temperatures climb into the low-to-mid 40s Fahrenheit. This typically happens from late February into early March in a normal winter — cold winters push it toward mid-March, mild winters can trigger movement in mid-February. Water temperature at the dam face can be tracked through the Wisconsin DNR's online water temperature monitoring or by contacting local guide services who track conditions daily through the spawn season.
The Window Is Short
The peak spawn concentration below the dam lasts 2–3 weeks in most years. Before the run peaks, walleye are scattered; after they spawn, they disperse back into the lake. The anglers who consistently limit out during the run are the ones who are there during the peak concentration window — not a week before it or a week after it. Following local guide reports or the Petenwell fishing community on social media is the most reliable way to know when to go.
Where to Fish — The Dam Structure
The Dam Face and Back Current
The most consistently productive area during the run is the back current area immediately downstream of the Petenwell Dam — the seam where the current from the dam face deflects and creates slack water. Walleye use this area to rest from the current and stage near the dam's concrete structure, which retains warmth that attracts baitfish. Position the boat in the back current area and pitch jigs across the current seam toward the dam face, working presentations back through the slack zone.
Depth Range
Walleye during the spawn run concentrate in shallower water than their winter holding depths — typically 4–16 feet, with the most consistent action in 6–12 feet near the dam structure. As the run progresses and water warms post-spawn, fish gradually move to deeper water and disperse. When you are finding the fish primarily in deeper water (15+ feet), the peak concentration window is typically past.
Presentations That Work
The Standard Setup
Quarter-ounce jigs in chartreuse, orange, or white with either curly tail plastics or tipped with a live minnow are the baseline approach. Pitch to the dam face, let the jig settle, and work it back through the current on a semi-tight line. Feel for the subtle tick of a walleye pick-up rather than a hard strike — spawn-run walleye often mouth a bait and spit it before committing. Keep contact with the jig through the entire presentation.
When Live Bait Outperforms
On cold-front days when walleye are lethargic and not aggressively chasing, live minnows on a jig outperform plastic tails consistently. The natural scent and movement of a live minnow is the trigger on tough days. Keep a dozen live minnows as backup even if you primarily fish plastics — the ability to switch when the bite slows is worth having.
Boat Positioning
Current management is the biggest technical challenge below the dam. Anchoring or using a trolling motor to hold position in the back current seam while pitching upstream and drifting presentations back through the zone is the standard approach. Anglers who cannot hold position drift past the productive zone before the presentation completes effectively. A quality trolling motor with current control is the most useful equipment upgrade for fishing this location consistently.
Frequently Asked Questions
The spring walleye run below Petenwell Dam peaks in late February into early March as water temperatures trigger walleye spawning staging in the dam tailwater. Back current seams in 4–16 feet near the dam face hold the highest concentrations. Quarter-ounce jigs with plastics or live minnows pitched across current and worked back through slack zones produce consistent results. The peak window is short — 2–3 weeks — and following local guide service reports is the most reliable way to know when to be there.
