Door County Salmon Season Underway; Rowley's Bay Launch Closed Through May 31

What's Biting

What's Next

With no real-time buoy readings available to pin down current conditions, the forecast must lean on seasonal patterns for Door County and Sheboygan — but early May is typically one of the most dynamic windows of the year on Lake Michigan, and several factors point to active salmon fishing in the days ahead.

Chinook and coho salmon are the primary focus. By early May, nearshore water temperatures along this stretch are usually climbing through the upper 40s toward the low 50s°F, concentrating baitfish at or near emerging thermoclines. Trolling remains the dominant technique: spoons, body baits, and flasher-fly combinations at varying depths allow anglers to probe both the shallow warm-water shelf and the deeper cold column where larger fish suspend. As surface temps continue warming through mid-May, downrigger presentations and deeper suspended lines typically become more critical to staying on fish.

Steelhead (lake-run rainbow trout) are worth targeting around river mouths and nearshore break structure through at least mid-May. The transition from active spawners to post-spawn fish staging near tributary outflows creates a mixed-bag opportunity — drift rigs with spawn sacks or small spoons near river mouths can produce. No current charter or shop reports are available to confirm specific timing this week, so plan conservatively and check with local tackle operations before heading out.

One immediate logistical factor: the Rowley's Bay boat launch in Liberty Grove remains closed through approximately May 31, per the WI DNR Lake Michigan Fishing Report. Northern Door County anglers need to identify alternate access well in advance — options in Sturgeon Bay and along the Green Bay side of the peninsula are worth scouting before you trailer up. The shallower Green Bay nearshore also typically begins holding smallmouth bass in late spring as bay water warms ahead of the open lake.

The waning gibbous moon provides significant overnight and pre-dawn light this week. During the brightest hours, salmon can drop deeper or become more selective near the surface; first light and late afternoon tend to be the most reliable bite windows. Lake Michigan can build dangerous wave action quickly in May with northerly or northeasterly winds — verify the marine forecast before every launch. If persistent southerly winds push warm air over the next several days, nearshore waters will warm faster and could draw active fish shallower; a hard wind shift to the northwest or northeast, conversely, can upwell colder water and push fish back toward the thermocline.

Context

For Door County and Sheboygan-area anglers, early May sits squarely in the heart of the spring salmon and steelhead season — one of the most eagerly anticipated windows on the Great Lakes calendar. Chinook and coho salmon are typically feeding actively near the surface or upper water column as nearshore temperatures climb through the 50°F range, tracking alewife schools staging along thermal gradients. Steelhead runs from tributaries are usually winding down or transitioning to post-spawn fish near river mouths by the first week of May, making this a productive overlap period for multiple species.

The 2026 season carries an unusually encouraging population backdrop. The WI DNR Lake Michigan Fishing Report notes a record coho harvest in 2024 — more than 210,000 fish — alongside the strongest Chinook tally since 2012 at over 160,000. The DNR credits strong recent alewife year classes for dramatically improving stocked-fish survival rates. Those same cohorts are now mature fish available to spring 2026 anglers, and the forage base supporting them appears healthy entering this season.

The lake whitefish picture is considerably less optimistic. Both Great Lakes Now and the WI DNR Lake Michigan Fishing Report flag ongoing stock declines across the lower Great Lakes. The WI DNR convened a public meeting in October 2025 to gather input on revised Total Allowable Catch limits for Lake Michigan and Green Bay whitefish — a clear signal that management is responding to population pressure. Anglers targeting whitefish should check current regulations carefully before keeping fish, as limits and seasons may change.

The Rowley's Bay boat launch closure is a facility improvement, not a fisheries indicator — but it does restrict access along a productive stretch of northern Door County coastline during a high-value time of year. No comparative spring 2025 data is available in current reports to benchmark how this May's fishing tracks against last year's opener.
