Knudson's Bay (North Dakota) — one of the area's fishing spots. About 58 ha in area. Salt water, not fresh — so this page carries its own marine bite forecast. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Other nearby waters
The shoreline is moderately indented: bays and points alternate with even stretches. The islands add structure: drop-offs around their perimeter and channels between them and the bank. Smaller than 9 of the 11 waters nearby.

Look for structure — reefs, flats, channel edges; work them slowly near the bottom.
Knudson's Bay — Wednesday, October 21
The bite is weak — fish are sluggish. 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 53 °F — inside the 43–59 °F comfort range for Chinook salmon, so baseline activity is high.
Chinook salmon 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 0.03 inHg 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.
October is a slow season for Chinook salmon: the best months fall at another time of year.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like +46°
The day is 3 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.
