Lake Michigan salmon strong as DNR reviews smallmouth, whitefish rules

What's biting

What's next

With no fresh buoy or gauge readings in today's feed, we can't call an exact thermocline depth for the next few days, but the standard early-August pattern on Lake Michigan off Door County and Sheboygan holds: surface temps near their yearly peak, forcing Chinook, coho, and lake trout down into cooler water, typically well below the top 20-30 feet. Expect trollers running deep with downriggers, spoons, and flasher-fly combos to keep finding fish in that zone through the next few days, with early-morning and late-evening windows offering the best shot at fish pushed slightly shallower by low light.

Given the WI DNR's report of a record 2024 coho harvest and the strongest Chinook numbers since 2012, this season's salmon fishery is coming off healthy stocked and wild year classes, so there's no reason to expect the deep-water bite to taper off through the rest of August. If that strength carries forward, look for consistent action to continue into the fall run as fish start staging closer to river mouths.

Smallmouth bass should stay a solid nearshore option through this stretch, working rock piles, gravel, and drop-offs in the mid-depths. The DNR's active public-meeting process on Green Bay and northern Lake Michigan smallmouth management is itself a signal that this fishery is drawing enough pressure to warrant a closer regulatory look, which is generally a sign of a fishery holding up well rather than declining.

Weekend planning should account for typical August boat traffic on popular Door County and Sheboygan launches; no specific closures are noted in today's feed (the earlier-season Rowley's Bay boat launch closure was scheduled to lift by May 31, well before this window). Anglers pursuing whitefish should watch for updates out of the DNR's ongoing lake whitefish total allowable catch process, since any near-term rule changes could affect access or limits later this year.

Without direct captain or shop reports for this specific window, treat the above as seasonal expectation rather than a confirmed pattern. Check back as fresh on-the-water intel comes in, and always verify current regulations and any access notices directly with the WI DNR before heading out.

Context

Door County and Sheboygan's Lake Michigan fishery has followed a well-documented recovery arc in recent years, and the WI DNR's data points to that trend continuing. The 2024 season produced a record coho salmon harvest (over 210,000 fish) and the strongest Chinook harvest since 2012 (over 160,000 fish), which the DNR attributes to improved alewife year-class survival feeding stocked and wild salmon. That's a meaningfully stronger baseline than the leaner Chinook years earlier in the 2010s, when forage-base crashes suppressed salmon numbers across the lake.

Smallmouth bass management is getting fresh attention too. The DNR's public meetings on Green Bay and northern Lake Michigan smallmouth bass reflect a fishery that has grown popular enough to need a closer regulatory look, which tracks with how smallmouth fishing on Lake Michigan's Wisconsin waters has trended over recent seasons.

Today's feed doesn't include direct comparative signals for this exact week (no captain, charter, or shop "what's biting" reports came through for Door County or Sheboygan specifically), so we can't say definitively whether this week's bite is running early, late, or on the typical early-August schedule for the region. What is available, the DNR's harvest data and ongoing management discussions on salmon, smallmouth, and whitefish, points to a fishery under active stewardship and coming off strong recent seasons, a reasonable baseline for anglers planning trips this month. We'll have sharper week-to-week comparisons once more granular on-the-water reports come through.
