River Rivière des Mille Îles (Quebec) — a popular fishing spot. About 41 km long. Flows into Rivière des Prairies, Main stem Saint Lawrence River drainage basin. Close by — Laval, Town of Mount-Royal and Côte Saint-Luc. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.

The course is moderately sinuous: pools are scoured at the bends and riffles run between them.

|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Black crappie | active | active |
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses. The water's cold — fish it more delicately and slowly.
Rivière des Mille Îles — Tuesday, October 20
The bite is strong — fish are active. Pressure is rising — activity tends to be more subdued. Peak 07:00–09:00 and 17:00–19:00.
The computed water temperature is around 4 °C — inside the 1–10 °C comfort range for Arctic char, so baseline activity is high.
Arctic char works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is dropping 1 hPa 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.
October is an active season for Arctic char here.
These are the same values the bite curve above was computed from. How the forecast works
Cloudy · feels like -5°
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.
What are solunar periods?Blue check: this species appears as a catch in reports for this waterbody.
