The run corridorThe mouthBoyne River — the run stops here
The colour is this river's run stage today, read off MDNR
run-timing guidance. Where along the corridor the fish are is not
modelled here — only the sixteen rivers the staging estimator covers
carry that.
Drawn 1 October 2026, north up, and it is a map of the river rather
than of the lake it runs from.

The Boyne is a short run off Lake Michigan — 4.0 corridor miles across four NHD reaches, ending at
the Boyne River dam, which USACE NID records as MI00515 on the Boyne River with the Federal Energy
Regulatory Commission as source agency. Most of that length is harbour rather than river: the
pierheads and harbour mouth run from 0.0 to 1.61 river miles, the river mouth from 1.61 to 3.95,
and the lower river occupies only the sliver from 3.95 to 3.99.
Steelhead carry two runs on one calendar, October through May, with a fall push that winters in the
river and a spring peak in March and April. Chinook stage off the harbour through August and enter
as the river cools, peaking in October; coho overlap them and hold later, peaking October into
November. Lake-run brown trout run September to November and stay after the salmon. The windows are
month-grained.
The questions about this river
One page each, answered from the same records as this one.
Each window is calendar guidance curated from the state's own run-timing prose, not a
regulation and not an observation. The stage beside it is this site's reading of that
window against 1 October 2026.
Chinook salmon — Aug–Octpeak Oct
First runners.
Fish stage off the harbour through August and enter as the river cools; the run peaks in October.
Coho salmon — Sept–Novpeak Oct–Nov
First runners.
Overlaps the chinook run and holds later; peak October and November.
Lake-run brown trout — Sept–Novpeak Oct
First runners.
Runs with the salmon and stays after them; peak October.
Steelhead — Oct–Maypeak Mar–Apr
Staging, 1 day out.
Two runs on one calendar — a fall push from October that winters in the river, and the spring run that peaks March through April.
The ceiling
Boyne River is where the run stops. Everything above it is upstream of the
fishery — a fish cannot pass it, so the water above holds resident trout and not run fish,
whatever the calendar says.

Access
No state boating access site falls inside this corridor's box. That is the record saying
nothing, not this page saying there is no way in — the public land layer on the live map
is the better answer for a river fished from the bank.
Great Lakes tributary rules are their own rules: seasons, gear and possession on run water
differ from the inland trout regulations, and they differ by river and often by reach.
Michigan's regulation summary is here, and the
state's own guide is the regulation.
Tackle
General guidance by species, not by river — there is no record of what a given river fishes
best with, and a page that invented one would be worse than a page that says so.
Chinook salmon
Spinning: a medium-heavy 8'6"–9' rod, 15–20 lb line, heavy spoons and crankbaits off the pier, skein or spawn under a float in the river.
Coho salmon
Spinning: a medium 7'–8'6" rod, 10–14 lb line, small spoons and spinners. Coho chase, and a moving bait outfishes a still one.
Lake-run brown trout
Spinning: a medium 7'–8' rod, 8–12 lb line, minnow plugs and spoons fished at dusk and after dark, which is when these fish move.
Steelhead
Float fishing: a long 10'6"–13' rod, 8–12 lb main line, spawn bags, beads or jigs under a slip float — the method that covers a run without wading it.
