Post-spawn bass and walleye settling into summer patterns on Michigan waters

What's Biting

What's Next

With the Grand River at 3,700 cfs and entering typical early-June stability, the system should remain fishable through the week barring significant rainfall upstream. At this level the Grand runs at a pace that concentrates walleye and smallmouth in slower seams behind current breaks: inside bends, log jams, and deeper channel edges are worth probing with jigs and soft plastics.

Wired 2 Fish flags the post-spawn period as one of fishing's more demanding windows for smallmouth. The fish have scattered off beds, and their movements can seem random. One day they're active on shallow flats; the next they've pushed to deeper rock structure. The consistent producers right now, per Wired 2 Fish, are baits that cover water efficiently: tubes, drop shots, and finesse rigs around rocky transitions. On the Great Lakes nearshore flats, smallmouth that haven't fully committed to summer depth will still respond to presentations worked through the 8 to 15 foot range.

Tactical Bassin leans into the offshore angle for June bass, advocating for a wobble head jig and shaky head worm combination as the go-to two-bait rotation on unfamiliar lakes. The approach: use electronics to mark structure, drift the flats outside spawning areas, and work both baits through the same zone to identify the day's preferred presentation.

Fishing the Midwest points out that weedlines are filling in across Midwest waters now that the open-water season is in full swing. In Michigan's inland lakes and along the shallower Great Lakes bays, the developing green edge is worth targeting as a morning bite window. Topwater and shallow crankbaits along the outer weed edge work well before light penetration pushes fish deeper; afternoons favor soft plastics worked along the deeper edge of the mat.

June is traditionally the window when Great Lakes walleye shift from post-spawn staging to summer feeding grounds. Trolling with divers and spinners along soft-bottom breaks parallel to the main river channel is a standard approach this time of year. No charter or tackle-shop intel was available this cycle to confirm the specific current bite, so treat this as a seasonal framework rather than a confirmed report.

Context

Without detailed condition data from the MI DNR Weekly Fishing Report snapshots captured in this cycle's feed, a direct comparison to prior seasons isn't possible. The MI DNR published reports every week from May 6 through June 3, suggesting routine monitoring has continued through the pre-summer transition, but specific regional breakdowns weren't available in the pipeline.

A 3,700 cfs reading on the Grand River in early June is consistent with the river's typical late-spring profile. The Grand historically runs higher in May from snowmelt and spring rain, then tapers toward lower summer base flows through June and July. A reading in the low thousands of cfs in the first week of June is normal and indicates conditions moving through transition: past the high, off-color runoff of late spring, but not yet at the low-clear summer levels that call for finesse presentations and early-morning timing.

Anglers who fished the Grand River during the earlier MI DNR report windows, from May 6 through May 27, would have been targeting the tail end of the spring walleye run. By early June, that post-spawn transition is well underway and walleye are shifting toward their summer structure.

The waning crescent moon on June 9 typically favors more concentrated daytime feeding windows, with fish less active overnight and more responsive during mid-morning hours. On the Great Lakes proper, June historically marks the beginning of salmon and steelhead staging in open water, though tributary fishing for those species is typically winding down as water temperatures rise. Fishing the Midwest frames the current moment as the heart of the open-water season: a time when versatility pays off and anglers willing to probe weedlines, work rivers, or target offshore structure tend to find the most consistent action.
