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 Pentwater's run corridor is short for this stretch of Lake Michigan shore — 10.43 miles across 24 NHD reaches, with pierheads and harbour mouth to 0.99, river mouth to 2.34, and lower river to the end. Nothing closes it: NID lists no structure on this mainstem, so the corridor runs to the end of it, which is a claim rather than a gap. Two state boating access sites sit inside it, Pentwater Municipal and John Gurney Park.

Chinook run Aug–Oct with an October peak, coho Sept–Nov peaking October and November, and steelhead hold two runs on one calendar, Oct–May — a fall push from October that winters in the river and a spring run peaking March through April. Lake-run browns run Oct–Nov between 45 and 58°F: anglers call the ecotype a coaster brown, though the word properly belongs to Lake Superior, and there is a spring feeding push in May behind the October spawning peak. The windows are month-grained.

The questions about this river

One page each, answered from the same records as this one.

What runs the Pentwater River

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–Oct peak Oct First runners. Fish stage off the harbour through August and enter as the river cools; the run peaks in October.
Coho salmon — Sept–Nov peak Oct–Nov First runners. Overlaps the chinook run and holds later; peak October and November.
Steelhead — Oct–May peak 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.
Lake-run brown trout — Oct–Nov peak Oct45–58°F Staging, 1 day out. The lake-run ecotype anglers call a coaster brown, though the word properly belongs to Lake Superior; a spring feeding push in May and the spawning run behind the salmon, peak October.

The ceiling

No barrier inside the run. The corridor runs to the end of the mainstem, which is a claim from the National Inventory of Dams rather than a gap in the data — the NID lists no structure on this river.

No barrier inside the run. NID lists no structure on this mainstem, so the corridor runs to the end of it — a claim, not a gap.

Access

State boating access sites inside the corridor's box, from the MDNR Boating Access Sites record. A ramp is not a wade-in — these are where a boat and a car go, and the bank between them is a question for the public land layer on the live map.

Regulations

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.
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.
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.
