Sand River (Alberta) — a spot well known among anglers. About 189 km long. Flows into Beaver River, Churchill river basin. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Cloudy: 3–14 °C
The bite is strong — fish are active. Weather is steady, with no sharp swings — fish behave predictably.
Best time — 07:00–09:00 (dawn bite) and 20:00–22:00 (dusk bite).
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.
The water's turning murky — go with bright, noisy lures: spinner or fly.
Bring a warm jacket — it's noticeably colder on the water than on shore. Rain is expected — don't forget a rain jacket or a waterproof shell.
Worth going — it's a productive day.
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 2 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.
September is an active season for Brook trout here.
These are the same values the bite curve above was computed from. How the forecast works
Cloudy · feels like +8°
The day is 4 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
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.
