The pale water is where chinook were holding on
2026-09-30 — 91% of the run was still out on
Lake Huron, which this picture does not reach.
That day's gauge and lake readings were measured. Drawn 1 October 2026, north up, and it is a map of the river rather
than of the lake it runs from.

The Rifle is a Saginaw Bay river, one of the few long lake-run corridors that answers to Lake Huron
rather than Lake Michigan: 55.0 miles across 94 NHD reaches, free-flowing through the whole of it.
Nobody has published where the run stops, and no upstream zone is drawn — the reach is long and
low-gradient rather than ending at a wall. The pierheads and harbour mouth carry to river mile 3.21,
and lower river runs from there to 54.99.
The calendar is Huron's, not Michigan's west shore. Steelhead are the run that carries these rivers
now, 1 Oct – 31 Dec with a spring peak in April. Chinook are thin and variable, 15 Aug – 31 Oct:
Lake Huron's alewife collapsed in 2003-04 and the chinook fishery went with it. Lake-run browns run
20 Oct – 31 Jan, entering between 45 and 58°F. Pink salmon are month-grained, Aug–Sept, heaviest in
odd-numbered years.
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.
This river is one of the sixteen the staging estimator models, so the window is shown in
the estimator's dated form. Those dates are one statewide set, the same on all sixteen
rivers, and no more river-specific than the months they restate — what the estimator adds
here is the daily staging read, not a sharper calendar.
Chinook salmon — 15 Aug – 31 Octpeak 15 Aug – 15 Oct
Peak run.
Thin and variable; peak September. Lake Huron's alewife collapsed in 2003-04 and the chinook fishery went with it. Carried as a thin run rather than dropped, because fish still return to the stocked rivers — but a Huron chinook run is not a Lake Michigan one and this layer will not draw it as though it were.
Pink salmon — Aug–Sept
Tail-off.
Naturalised, and heaviest in odd-numbered years — the two-year life cycle is what makes the run alternate.
Steelhead — 1 Oct – 31 Decpeak 15 Oct – 15 Dec
Staging, 1 day out.
The run that carries these rivers now. Fall push from October, spring peak in April.
Lake-run brown trout — 20 Oct – 31 Janpeak 1 Nov – 15 Jan45–58°F
Off-season.
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 coordinate is cited for the top of this run. Free-flowing through its lake-run reach off Saginaw Bay, and nobody publishes where the run stops. The corridor is drawn to the end of the mapped mainstem, which is where the record stops.

River miles from the harbour mouth, walked up the NHDPlus HR mainstem. Fish arrive at the
bottom of this table and work up it as the river cools and rises.
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.
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.
Pink salmon
Light spinning tackle is enough — a 6'6"–7' rod and 6–10 lb line. Small pink and orange spinners, spoons and flies.
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.
