Reservoir Cowan Lake (Ohio) — a spot well known among anglers. About 2.8 km² in area. This page shows an hourly bite forecast for today and the week ahead; the algorithm factors in the weather, atmospheric pressure, and the moon phase.
Other nearby waters
The shoreline is heavily indented — bays, points and spits. Look for pike at the mouths of the bays and on the drop-offs behind the points. The islands add structure: drop-offs around their perimeter and channels between them and the bank. The largest water around: all 9 neighbours are smaller.
The wind builds its wave along the west — east axis — 3 mi of open water; along north — south there is only 1 mi. When it runs down the main axis, the calm water sits against the bank it blows from, while the wave and the silt go to the far one — and the fish follow them there to feed.
Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots.
Cowan Lake — Tuesday, October 20
The bite is moderate — fish feed in short bursts. Weather is steady, with no sharp swings — fish behave predictably. Peak 08:00–09:00 and 18:00–20:00.
The computed water temperature is around 58 °F — inside the 57–75 °F comfort range for Black crappie, so baseline activity is high.
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 flat: it moves no more than 0.00 inHg over the day, so the weather isn't shifting today's bite.
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.
October 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 +56°
The day is 2 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
Geomagnetic fieldG1 geomagnetic storm, Kp 4.7
Kp index — NOAA data. Not part of the bite score: catches show no link between geomagnetic storms and the bite.
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.
