Center Lake (Iowa) — a spot well known among anglers. About 1 km² in area. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.
The shoreline is moderately indented: bays and points alternate with even stretches. Larger than 15 of the 19 waters nearby.
The longest fetch is 1 mi along the north-east — south-west axis: wind along it builds a wave on the open water and pushes silt and food towards the lee bank.

Center Lake — Wednesday, October 21
The bite is strong — fish are active. Weather is steady, with no sharp swings — fish behave predictably. Peak 07:00–09:00 and 18:00–20:00.
The computed water temperature is around 59 °F — inside the 57–75 °F comfort range for Black crappie, so baseline activity is high.
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 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 an active season for Black crappie here.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like +65°
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.
