Fall Chinook Run Holds Michigan's Great Lakes Tributaries
Michigan's fall Chinook Salmon run remains the headline signal on the state's Great Lakes tributaries this week. Anglers on the Michigan Sportsman Forum report that the Little Manistee Weir egg-take operation came online the week of September 21, with the DNR's first collection day set for September 29, evidence that salmon are staged in numbers below the weir, the typical pattern for this stage of the run. The Michigan DNR's Weekly Fishing Report, which tracks conditions across the Lower and Upper Peninsulas plus a dedicated Great Lakes section, published its October 7 edition this week, landing squarely in the heart of the fall transition period.

What's next
Expect the salmon run to hold through the next several days, with fish continuing to stage below weirs and dams on West Michigan's river systems, the typical rhythm once an egg-take operation is active, with numbers usually building through mid-October. The waning crescent moon brings darker pre-dawn and dusk windows over the coming nights, conditions that often draw staging salmon into shallower runs and improve early and late sight-fishing. On the Grand River, cooling water typically pushes Walleye into deeper current breaks as fall progresses, a seasonal shift worth planning around now. Tactical Bassin's recent fall coverage frames October as a strong window for Largemouth Bass and Smallmouth Bass chasing baitfish on shallow flats and around structure, a pattern that should keep producing through the next couple of weeks as water keeps cooling. Weekend planning should center on early mornings and the hour around dusk, when tributary traffic and staging-fish visibility are both at their best.
Context
Early October sits right in the heart of Michigan's fall transition: Great Lakes surface water is cooling toward turnover, salmon runs are active on tributaries statewide, and inland lakes are shifting from late-summer patterns into the cooling-water feeding window that typically runs through November. The Little Manistee Weir egg-take timeline reported this week tracks with a normal fall run; Michigan's Chinook Salmon typically stage below weirs through late September and into October before the bulk of spawning activity. For Great Lakes anglers, this window usually marks the start of stronger nearshore activity as baitfish concentrate and predator species follow, a pattern that should continue building into late fall.
