Squannacook River (Massachusetts) — a spot well known among anglers. About 28 km long. Flows into Nashua River. Close by — Fitchburg and Leominster. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Nearest towns and cities
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. Longer than 3 of the 4 rivers nearby.

Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.
Squannacook River — Wednesday, October 21
The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite. Peak 07:00–09:00 and 17:00–19:00.
The computed water temperature is around 56 °F — inside the 39–57 °F comfort range for Atlantic salmon, so baseline activity is high.
Atlantic salmon works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is dropping 0.09 inHg 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 average month for Atlantic salmon here.
These are the same values the bite curve above was computed from. How the forecast works
Cloudy · feels like +42°
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.
