The pale water is where chinook were holding on
2026-09-30 — 2% 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.
1 state boating access site fall inside the Black River (South Haven) corridor in MDNR's own record — Black River. The run is 13.1 miles long and splits into the pier at river mile 0.0–1.6, the mouth at river mile 1.6–2.3 and the lower at river mile 2.3–13.1; the pier and the mouth are boat and breakwall water and the miles above them are waded. The nearest town we map is Grandville, 43.7 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 0.0–1.6
Breakwall and pier. Cast tackle and a long-handled net; no wading here.
Mouth — river mile 1.6–2.3
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 2.3–13.1
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.
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
No barrier inside the run — the corridor runs to the end of the mainstem, and the top of the
fishery is wherever the water gets too small rather than a structure you can park at.
Nearest towns
Straight-line distance from the corridor's midpoint to the towns we map. The roads are not
mapped here, so these are not drive times.
