The run corridorThe mouthHarpersfield Low Head Dam — the run stops here
The colour is this river's run stage today, read off Ohio EPA
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 30 September 2026, north up, and it is a map of the river rather
than of the lake it runs from.
Spinning and float tackle for the salmon and a fly rod for the steelhead is the short answer on the Grand River, and the long one changes by species: steelhead all run this corridor and they are not fished the same way. The water splits into 4 zones over 31.5 miles — pier to river mile 1.8, mouth to river mile 3.6, lower to river mile 9.6 and upstream to river mile 31.4 — and the pier is a different fishery from the water above the first holding pool. Harpersfield Low Head Dam is the ceiling: no run fish above it, whatever the calendar says, so the whole fishery is inside those miles. Tackle guidance on this site is per species and never per river.

Tackle, by species
General guidance per species and never per 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.
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.
Fly: 7–8 weight single-hand or a switch rod, egg and nymph patterns on a dead drift, swung streamers in the fall push. 6–10 lb tippet.
Zone by zone, mouth to ceiling
The corridor's own zones, with river miles walked up the NHDPlus HR mainstem from the harbour
mouth. Fish arrive at the top of this table and work down it as the river cools and rises.
Pier — river mile 0.0–1.8
Breakwall and pier. Cast tackle and a long-handled net; no wading here.
Mouth — river mile 1.8–3.6
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 3.6–9.6
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 9.6–31.4
Above the first holding water, up to the ceiling. Wading and bank fishing; too small or too shallow for most boats.
The ceiling
Harpersfield Low Head Dam stops the run. There are no run fish above it whatever the calendar says,
so every mile of this fishery is below it — which is also why the water immediately under a
ceiling is the most crowded water on a run river in September.
