Staging · Steelhead as of 1 October 2026, 1 day out
31.5 miles of run water on the Grand River, from Lake Erie up to Harpersfield Low Head Dam. 1 species run it, on windows curated from Ohio EPA guidance.
The Grand runs 42.2 miles of corridor over 60 NHD reaches to a hard ceiling at the Sixth Street Dam. The pierheads and harbour mouth hold the first 3.08 miles, the river mouth reaches 13.22, the lower river runs to 33.81, and the last 8-odd miles above the first holding water climb to 42.19. Eight state boating access sites sit in that corridor, among them Pigeon Lake, Robinson, Bass River Recreation Area and Grand River Park.
The windows here are written out as dates rather than months, though they are the staging estimator's statewide set and not a Grand-specific reading: chinook 15 Aug – 31 Oct, coho 1 Sep – 30 Nov, steelhead 1 Oct – 31 Dec, and lake-run brown trout 20 Oct – 31 Jan with a peak of 1 Nov – 15 Jan. The Grand's distinguishing fish is lake sturgeon, spawning on the gravel immediately below the Sixth Street Dam in the middle of Grand Rapids from April into June, peaking in May. Temperature rather than the date is the trigger — the run starts around 55°F and is finished above about 64°F. It is catch-and-release only, a state-threatened species with the possession season closed on this water.
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.
Harpersfield Low Head Dam is where the run stops. Everything above it is upstream of the fishery — a fish cannot pass it, so the water above holds resident trout and not run fish, whatever the calendar says.

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.
No state boating access site falls inside this corridor's box. That is the record saying nothing, not this page saying there is no way in — the public land layer on the live map is the better answer for a river fished from the bank.

The Grand River river page — gauges, temperature and regulations by reach →
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. Ohio's regulation summary is here, and the state's own guide is the regulation.
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.
