Flat River Reservoir (Rhode Island) — a spot well known among anglers. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure.
Wednesday, October 21
Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots.
Flat River Reservoir — Wednesday, October 21
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite. Peak 07:00–09:00 and 17:00–19:00.
The computed water temperature is around 54 °F — colder than the 57–75 °F comfort range for Black crappie: the fish conserves energy and takes more cautiously.
Black crappie works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is dropping 0.06 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 active season for Black crappie here.
These are the same values the bite curve above was computed from. How the forecast works
Cloudy · feels like +40°
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 fieldquiet, Kp 3.7
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.
What are solunar periods?Partly cloudy: 48–68 °F

The shoreline is heavily indented — bays, points and spits. Look for pike at the mouths of the bays and on the drop-offs behind the points.
The longest fetch is 4 mi along the north-west — south-east axis: wind along it builds a wave on the open water and pushes silt and food towards the lee bank.
Blue check: this species appears as a catch in reports for this waterbody.
