Assiniboine River (Manitoba) — a spot well known among anglers. About 894 km long. Flows into Red River of the North, Lake Winnipeg basin. Close by — Brandon, Winnipeg and Portage la Prairie. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure.

The course meanders heavily: the current digs a pool on the outside of every bend and builds a bar on the inside. Those pools under the undercut bank are where pike typically sits.

|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Grayling | fair | slow |
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses. The water's cold — fish it more delicately and slowly.
Assiniboine River — Tuesday, October 20
The bite is moderate — fish feed in short bursts. 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 6 °C — inside the 1–10 °C comfort range for Arctic char, so baseline activity is high.
Arctic char 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.
October is an active season for Arctic char here.
These are the same values the bite curve above was computed from. How the forecast works
Drizzle · feels like 0°
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.
What are solunar periods?Blue check: this species appears as a catch in reports for this waterbody.
