Bay Foster Arm (Alberta) — a spot well known among anglers. About 3.7 km² in area. A coastal water: the bite here is modelled for the sea, not for a river or a lake. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.
Alberta: the months when each species peaks and when it goes quiet. The current month is outlined.
| Fish | January | February | March | April | May | June | July | August | September | October | November | December |

Look for structure — reefs, flats, channel edges; work them slowly near the bottom. The water's cold — fish it more delicately and slowly.
Foster Arm — Tuesday, October 20
The bite is strong — fish are active. 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 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 rising 4 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 Brown trout here.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like -4°
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 fieldunsettled, Kp 4
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.

The shoreline is moderately indented: bays and points alternate with even stretches. The largest water around: all 5 neighbours are smaller.
The wind builds its wave along the west — east axis — 5 km of open water; along north-west — south-east there is only 2 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.
