Griggs Reservoir (Ohio) — one of the area's fishing spots. About 1.5 km² in area. The town of Columbus is nearby. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Recorded 3 catches here. Most commonly caught: Channel catfish, Black crappie, Flathead catfish. Peak season: year-round.
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite.
Best time — 06:00–08:00 (dawn bite) and 20:00–21:00 (dusk bite).
Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots.
In clear water, natural colors work best: small jig or minnow bait.
It's a hot day — a hat, sunglasses, and plenty of water are a must.
Worth going — it's a productive day.
The computed water temperature is around 76 °F — warmer than the 57–75 °F comfort range for Black crappie: in the heat it drops deeper and feeds less often.
Black crappie works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is dropping 0.03 inHg over the day — fish are usually more active ahead of a weather change.
One more input — the moon's feeding windows: within their hours the score sits higher than across the rest of the day. The window times are in the “Solunar feeding periods” card below.
September is an active season for Black crappie here.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like +97°
The day is 3 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
The windows are set by the moon's transit and rise, and the forecast above already accounts for them: within these hours the bite score sits higher than across the rest of the day, while the day's overall level still comes from the catch-calibrated model.
