Chinook and coho primed along Door County and Sheboygan as June peaks

What's Biting

What's Next

The waning crescent moon this week means minimal overnight illumination, which tends to push salmon feeding into the dawn and dusk windows rather than overnight surface activity. On open Lake Michigan, standard trolling setups deserve priority attention: downriggers for precise depth control at the thermocline, divers for intermediate-depth coverage, and copper line for additional versatility are all worth having rigged as fish transition from spring staging into early-summer offshore patterns.

No buoy data is currently available for this stretch of the lake. As June surface temperatures climb, salmon typically suspend near the thermocline, often anywhere from 40 to 80 feet down depending on how quickly summer stratification sets in. Checking with a local marina or connecting with another boat already on the water before committing to a depth program will save time. Once the productive band is dialed in, action can hold through the morning hours before surface heat pushes fish deeper.

For smallmouth bass, mid-June typically marks the post-spawn transition, with fish moving off gravel beds and onto adjacent rocky points and hard-bottom structure. Tactical Bassin reported strong Great Lakes smallmouth action on swimbaits in windy conditions, specifically calling out the Dark Sleeper as the power option and the Spark Shad as the finesse follow-up when fish need a more natural presentation. Rocky transition zones off Door County points and Sheboygan harbor structures are worth covering systematically.

Looking at the weekend window: open-water trolling on Lake Michigan is most productive when seas are manageable, ideally under 2 to 3 feet. Anglers in Sheboygan and Door County should pull a NOAA marine forecast before trailering a boat. Shore-based opportunities near harbor entrances and pier heads typically improve during calmer morning hours, with coho and brown trout occasionally working near the surface during low-light periods.

Lake whitefish are present in northern Lake Michigan and Green Bay, though the WI DNR is actively working through a proposed new total allowable catch framework for 2026. Anglers should confirm current regulations before targeting whitefish, as the new management structure may affect limits this season.

Context

Lake Michigan's 2024 salmon season was exceptional by any recent measure. The WI DNR Lake Michigan Fishing Report documented record coho harvests exceeding 210,000 fish alongside 160,000-plus Chinook, the highest Chinook total since 2012. The DNR attributed the strong returns to robust recent alewife year-classes that improved survival rates for stocked salmon. Alewife abundance is the single biggest driver in Great Lakes salmon dynamics: when forage is plentiful, stocked Chinook and coho convert efficiently and reach harvestable sizes faster. For Door County and Sheboygan anglers, that forage baseline provides a favorable structural backdrop heading into the 2026 season.

Historically, mid-June sits at the transition between spring staging and full summer offshore patterns on this stretch of Lake Michigan. Surface temperatures that begin the month in the upper 40s to low 50s typical for the region generally push into the mid-50s by the third week of June, triggering the thermocline-chasing behavior that defines summer salmon trolling. Whether 2026 surface temps are running ahead of or behind that historical average cannot be confirmed without current buoy data, and no charter or tackle-shop reports are included in this feed to offer a local ground-truth comparison. That gap is worth noting honestly.

For smallmouth management context: the WI DNR hosted public meetings in late 2024 on the future of smallmouth bass management in Green Bay and northern Lake Michigan, signaling active regulatory attention to a fishery that Door County anglers have long relied on. No new restrictions have been flagged in available reports, but the management conversation reflects the DNR's awareness of the species' long-term importance in this corner of the lake.

On access: the Rowley's Bay boat launch in Door County, taken offline for structural improvements and closed through approximately May 31, adds recent context for anglers who may have planned early-season trips and found the ramp unavailable. That closure is now behind us, and the improved ramp should be in better shape for the balance of the summer season.
