Crater Lake (Saskatchewan) — one of the area's fishing spots. About 8 ha in area. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Saskatchewan: the months when each species peaks and when it goes quiet. The current month is outlined.

Crater Lake — Wednesday, October 21
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 7 °C — inside the 7–16 °C comfort range for Brook trout, so baseline activity is high.
Brook 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 9 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 peak season for Brook trout here.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like +6°
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.

Crater Lake — Wednesday, October 21
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 basin is close to regular: the bank runs smooth and natural cover is scarce, so fish hold to the few anomalies — inflows, drop-offs and weed edges.
The water is sheltered: there is almost no fetch, so wind stirs it up very little.
