River Eldridge Slough (Iowa) — a popular fishing spot. About 2 km long. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.
Recorded 1 catch here. Most commonly caught: Smallmouth bass. Peak season: May.
The bite is moderate — fish feed in short bursts. Weather is steady, with no sharp swings — fish behave predictably.
Best time — 06:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.
The water's turning murky — go with bright, noisy lures: small jig or minnow bait.
It's a hot day — a hat, sunglasses, and plenty of water are a must. Winds will be strong — wind protection helps, and be careful if you're in a boat.
An average day — best chances during peak windows.
The computed water temperature is around 79 °F — warmer than the 57–75 °F comfort range for Black crappie: in the heat it drops deeper and feeds less often.
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 rising 0.09 inHg over the day — the bite usually settles down after a rise.
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.
September 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 +98°
The day is 3 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
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.
