park lake (Alberta) — a popular fishing spot. About 87 ha in area. Nearest town — Lethbridge. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.
Cloudy: 1–11 °C
The bite is strong — fish are active. A thunderstorm is possible: activity rises before the front and drops after.
Best time — 06:00–09:00 (dawn bite) and 20:00–22:00 (dusk bite).
Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots.
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. 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 9 °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 5 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 +10°
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.
