Souris River (Saskatchewan) — a spot well known among anglers. About 420 km long. Flows into Assiniboine River, Lake Winnipeg basin. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.
Cloudy: 15–22 °C
The bite is strong — fish are active. A thunderstorm is possible: activity rises before the front and drops after.
Best time — 19:00–21:00 (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.
No special gear needed — seasonal clothing will do. A thunderstorm is possible — bring a rain jacket, and pack up at the first rumble of thunder.
Worth going — it's a productive day.
The computed water temperature is around 16 °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 flat: it moves no more than 0 hPa over the day, so the weather isn't shifting today's bite.
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 peak season for Brook trout here.
These are the same values the bite curve above was computed from. How the forecast works
Drizzle · feels like +14°
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.
