Lake Michigan Salmon Builds on Record 2024 Returns as Door County Summer Season Peaks

What's biting

What's next

Late June on Lake Michigan typically marks the heart of the open-water salmon season, and this year's waxing gibbous moon adds a useful planning window: increased light can extend feeding activity into the evening hours, especially for coho staging at shallower depths.

Without real-time buoy data, specific temperature breaks and thermocline depths are unknown for this report. Anglers should watch for cold-water upwelling that commonly pushes along the Sheboygan and Door County shorelines when northwest winds blow. When surface temps climb into the mid-60s range typical of late June, Chinook tend to drop to the thermocline between 60 and 120 feet, while coho often hold shallower, from 30 to 60 feet on cooler mornings.

For the next two to three days, wind direction will drive everything. Consistent south or southwest winds tend to lay the lake down and pull warm surface water toward the Wisconsin shoreline, pushing baitfish and the salmon following them deeper. North or northwest winds will blow that warm cap offshore and can stack fish near the surface at river plume lines and current edges off Door County.

Whitefish action may be limited heading into summer. The WI DNR Lake Michigan Fishing Report flagged the species for a total allowable catch review for 2026, pointing to populations that warrant conservative handling. Verify current limits before harvesting whitefish near Sheboygan or in Green Bay.

Smallmouth bass should be an increasingly productive option through the coming week. Door County's rocky reefs and cobble shorelines are classic summer smallmouth habitat, and bass typically settle into predictable post-spawn patterns by late June. Tube baits and drop shots worked along structure in 8 to 18 feet can produce consistent action when lake chop makes open-water trolling uncomfortable.

Early morning hours before lake chop builds typically offer the cleanest trolling conditions off Sheboygan. On rough Lake Michigan days, Door County's sheltered Green Bay side bays can hold calmer water and keep both salmon and smallmouth options on the table.

Context

The WI DNR Lake Michigan Fishing Report's 2024 harvest summary provides meaningful context for the 2026 season. The record coho harvest of more than 210,000 fish, combined with a Chinook total topping 160,000 (the best since 2012), reflects a recovery in alewife populations that had been suppressed for years. More alewife forage means better survival rates from stocking to catchable size, and for anglers familiar with Lake Michigan's boom-and-bust cycles tied to alewife abundance, this represents a notably positive stretch heading into the current season.

Typical for late June on this stretch of Lake Michigan, Chinook salmon are the anchor species for charter fleets running out of Sheboygan and Door County ports. The peninsula's proximity to Green Bay also opens walleye and smallmouth opportunities that the purely open-lake fishery south of Sturgeon Bay does not offer to the same degree. By late June most years, salmon have moved away from near-shore warming water and settled into offshore thermal structure, requiring downriggers or lead-core setups to reach them.

Per Wired 2 Fish, round gobies, initially considered a damaging invasive, have quietly become a critical forage base for smallmouth bass and other predators throughout the Great Lakes. In northern Lake Michigan and Green Bay, that ecological shift supports the robust smallmouth fishery around Door County's reef systems, the same population the WI DNR is now actively monitoring through public management meetings.

No comparative data from charter captains or tackle shops in the Door County or Sheboygan area was available for this report to benchmark 2026 against prior years at the same calendar date. The 2024 harvest numbers are the clearest available signal that the system is in a productive phase, though one strong season does not guarantee equivalent returns two years on.
