The run corridorThe mouthCroton Dam — the run stops hereThe piers — 9%
The pale water is where chinook were holding on
2026-09-30 — 91% of the run was still out on
Lake Michigan, which this picture does not reach.
That day's gauge and lake readings were measured. Drawn 30 September 2026, north up, and it is a map of the river rather
than of the lake it runs from.
8 state boating access sites fall inside the Muskegon River corridor in MDNR's own record, 509 parking spaces between them — Muskegon State Park - Snug Harbor, Hartshorn and High Rollway Thornapple. The run is 52.0 miles long and splits into the pier at river mile 0.0–2.1, the mouth at river mile 2.1–6.4, the lower at river mile 6.4–38.5 and the upstream at river mile 38.5–52.0; the pier and the mouth are boat and breakwall water and the miles above them are waded. The upstream end is Croton Dam, which is where the fish stop and where the water above holds resident trout instead. The nearest town we map is Newaygo, 11.8 miles from the corridor's midpoint in a straight line, with the water south-west of the town.

State access sites inside the corridor
From the MDNR Boating Access Sites record, filtered to this corridor's bounding box. 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.

Wade-in or boat, by zone
Pier — river mile 0.0–2.1
Breakwall and pier. Cast tackle and a long-handled net; no wading here.
Mouth — river mile 2.1–6.4
The harbour mouth and the first flat water. Boat and pier water, wadeable only where the river narrows above the turning basin.
Lower — river mile 6.4–38.5
The lower river — the holding water most of the run is caught in. Drift boat where it is wide enough, waded where it is not.
Upstream — river mile 38.5–52.0
Above the first holding water, up to the ceiling. Wading and bank fishing; too small or too shallow for most boats.
Zones are the corridor file's, cut on river mile. This site holds no wadeability survey, so the
note beside each zone is what the zone is and not a promise about any particular bank.
The upstream end
Croton Dam, at 43.4348,
-85.6653. Above it the water holds resident trout rather
than run fish, so it is the top of the fishery as well as the top of the corridor.
Nearest towns
