Salmon Trolling Season Gains Steam on Lake Michigan as Door County Access Shifts

What's Biting

What's Next

With Memorial Day weekend landing on a First Quarter moon, solunar activity will be moderate through the coming days, producing reliable but not peak feeding windows. On Lake Michigan, late May marks the transition from cooler spring conditions to early summer stratification. As upper-water layers warm, Chinook and coho that have been roaming near the surface will begin dropping toward the thermocline. Downriggers, divers, and weighted wire programs typically outperform flat lines by early June, and getting dialed into the right depth band will be the key adjustment this week.

Coho run shallower and closer to shore than kings, making them the more accessible target for smaller boats during this window. The WI DNR's 2024 harvest data, showing a historic coho return driven by healthy alewife forage, suggests the stocked population entering 2026 was in good shape. With typical stocking schedules, fresh coho should be feeding actively in nearshore and mid-lake water from Door County down through the Sheboygan area across the coming weeks. Stick to the upper 20 to 40 feet and work spoons or meat rigs on an inside-out spread.

Smallmouth bass in the Green Bay and northern Lake Michigan corridor, an area the WI DNR has been actively studying for management purposes, will be finishing the spawn or sliding into post-spawn patterns right now. Late May is historically prime for smallmouth in this region. Fish are either guarding nests in warmer bays and shallow rocky structure or moving aggressively to feed once the spawn wraps. Tube baits, drop-shots, and soft-plastic swimbaits worked along rocky points and shoals are classic late-May Door County producers.

Lake whitefish, which the WI DNR is currently evaluating for revised total allowable catch levels in Lake Michigan and Green Bay, will be settling back into deeper, cooler structure. Jigging small spoons or offering live bait near bottom in the 30 to 60 foot range is the conventional approach for this period, though success hinges on water temp at depth.

From a logistics standpoint, Rowley's Bay reopens May 31 at approximately 4 p.m. per the WI DNR. Memorial Day weekend trips to the northern Door County shoreline will need alternate launch sites until then.

Context

By late May, Lake Michigan's Door County and Sheboygan shores are typically entering the prime salmon trolling window. This is the period when stocked Chinook and coho that have been feeding on alewife through winter and spring begin concentrating at predictable temperature breaks, making them accessible to trollers working the nearshore zone. Charter fleets based from Sheboygan north through Sturgeon Bay traditionally see strong action build through June and peak in July, but late May is when early-season patterns start locking in.

What distinguishes 2026 is the strong baseline established in 2024. The WI DNR's harvest summary documented a record coho year, with over 210,000 fish, and the best Chinook performance since 2012, with more than 160,000 kings landed. The agency specifically linked those results to recent strong alewife year classes and the improved smolt survival they enabled. Lake Michigan's salmon fishery has historically cycled with alewife abundance, and a healthy forage base entering 2026 is a meaningful positive signal for the season ahead.

The WI DNR's concurrent attention to Lake Whitefish total allowable catch levels in Lake Michigan and Green Bay, as well as smallmouth bass management in the Green Bay and northern Lake Michigan corridor, reflects broader long-cycle fisheries stewardship across the full species suite Door County and Sheboygan anglers pursue. These are not week-to-week swing factors, but they underscore that the regional fish community is actively managed and monitored.

Without current buoy temperature data or direct on-water charter and tackle shop reports for this specific date, it is not possible to confirm whether this spring's bite is running early, late, or on schedule. The most reliable real-time intelligence will come from local launch ramps and captains operating out of Sheboygan and Sturgeon Bay once boats begin reporting Memorial Day weekend results.
