Little Tilston Lake (Ontario) — a popular fishing spot. About 4 ha in area. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Other nearby waters
The shoreline is moderately indented: bays and points alternate with even stretches. The islands add structure: drop-offs around their perimeter and channels between them and the bank. Smaller than 17 of the 19 waters nearby.
The water is sheltered: there is almost no fetch, so wind stirs it up very little.
Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots. The water's cold — fish it more delicately and slowly.
Little Tilston Lake — Wednesday, October 21
The bite is moderate — fish feed in short bursts. Pressure is rising — activity tends to be more subdued. Peak 08:00–10:00 and 18:00–20:00.
The computed water temperature is around 8 °C — colder than the 14–24 °C comfort range for Black crappie: the fish conserves energy and takes more cautiously.
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 rising 1 hPa over the day — the bite usually settles down after a rise.
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
Drizzle · feels like +7°
The day is 3 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 forecast. 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.
