Bay Columbia Reach (Alberta) — a popular fishing spot. About 175.8 km² in area. This is a sea water — its bite forecast is a marine one, computed apart from rivers and lakes. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.
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 largest water around: all 5 neighbours are smaller.
The wind builds its wave along the north-west — south-east axis — 96 km of open water; along north-east — south-west there is only 14 km. 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 structure — reefs, flats, channel edges; work them slowly near the bottom. The water's cold — fish it more delicately and slowly.
Columbia Reach — Wednesday, October 21
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite. Peak 08:00–10:00 and 18:00–20:00.
The computed water temperature is around 3 °C — colder than the 6–17 °C comfort range for Brown trout: the fish conserves energy and takes more cautiously.
Brown trout works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is dropping 6 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 Brown trout here.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like -5°
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.
