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

Wednesday, October 21
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses. The water's cold — fish it more delicately and slowly.
Rivière Anistuwach — Wednesday, October 21
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite. Peak 08:00–09:00 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. Under ice Ice cover is judged from the seasonal normal, so during a thaw the modelled water can read above freezing while the ice still holds.
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 3 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 -2°
The day is 4 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.
