Early-June Salmon Trolling Window Opens on Lake Michigan's Grand River Mouth

What's Biting

What's Next

With the Grand River holding at 3,670 cfs and Lake Michigan's nearshore zone typically climbing into the upper 50s to low 60s°F by early June (no buoy temperature reading is available this cycle), conditions over the next several days should remain stable and fishable at the river mouth. Anglers targeting Chinook salmon on the open lake should look for fish suspended in the developing thermocline — typically 50–150 feet down — using lead core, divers, or downriggers with spoons and meat rigs worked along the 60–100 foot contour between Grand Haven and Holland. The bite window often opens best in the first few hours after sunrise, especially with the reduced predawn light that accompanies the Last Quarter moon.

If the Grand River holds steady or edges lower into the weekend, steelhead stragglers may still be accessible near the pier heads at Grand Haven, though numbers will be thin as the spring run is well past its peak. Don't spend too much time on it — coho and Chinook are the better bets for boat anglers working open water right now.

Smallmouth bass are in post-spawn recovery mode. Tactical Bassin reported this week that the early-summer transition rewards anglers working chatterbaits across wind-exposed flats and dropping finesse presentations — shaky head worms and dropshot rigs — to fish grouped on offshore structure. Isolated current-washed rock piles near the Grand Haven breakwater and harbor mouth are worth targeting during low-light windows, particularly at first light under the Last Quarter phase.

Yellow perch should be transitioning toward their summer deep-water pattern, moving to 30–60 foot depths as surface temps climb. Vertical jigging with small blade baits or spinner rigs near bottom is the standard approach. Check current Michigan regulations before keeping perch, as zone-specific limits apply.

A legislative note worth tracking: Wired 2 Fish reports that House Bills 5801 and 5802 propose opening commercial netting for walleye and lake trout in Michigan state waters, drawing strong pushback from the recreational angling community. No immediate effect on 2026 season regulations, but worth monitoring if walleye or lake trout are part of your target list.

Context

Early June at the Grand River mouth and Lake Michigan nearshore zone is traditionally one of the year's stronger transition windows. The spring steelhead run — which typically peaks from late March through April at Grand Haven — is largely complete by the first week of June, but the Chinook and coho salmon trolling season is just hitting its stride. In a normal year, Chinook begin staging along the Michigan shoreline from Memorial Day onward and remain catchable through July, making this the opening of the early-summer salmon bite for both charter and private boat anglers.

The 2024 season provides a useful benchmark: the WI DNR Lake Michigan Fishing Report documented the best Chinook harvest since 2012 — more than 160,000 fish lakewide — alongside a record coho harvest surpassing 210,000. Both figures were attributed to strong alewife survival in recent stocking cycles. Michigan's stocked fish draw from the same forage base, so the current salmon cohort likely shares that nutritional advantage heading into the 2026 season.

The Grand River gauge reading of 3,670 cfs at Grand Rapids (USGS gauge 04119000) is consistent with a typical post-snowmelt, early-summer stabilization. Michigan rivers in this drainage generally crest in March and April and recede through June toward their low-water summer baseline. A reading in the low-to-mid thousands of cfs in early June is unremarkable and should not create hazardous conditions at the Grand Haven harbor mouth or impede boat access.

Direct comparative signal from a Michigan state agency is unavailable this week — the MI DNR Weekly Fishing Report page was inaccessible during data collection — so seasonal framing above draws on regional patterns and the broader Lake Michigan picture as reported by the WI DNR. If Wisconsin's 2025 stocking results mirrored the strong 2024 numbers, a productive early-summer bite is the reasonable expectation for Michigan nearshore waters as well.
