Carey–Lake Mead Detention Basin (Nevada) — a popular fishing spot. About 23 ha in area. Nearby towns: Las Vegas and Spring Valley. This page shows an hourly bite forecast for today and the week ahead; the algorithm factors in the weather, atmospheric pressure, and the moon phase.

The basin is close to regular: the bank runs smooth and natural cover is scarce, so fish hold to the few anomalies — inflows, drop-offs and weed edges. Larger than 14 of the 16 waters nearby.
The water is sheltered: there is almost no fetch, so wind stirs it up very little.

Carey–Lake Mead Detention Basin — Tuesday, October 20
The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite. Peak 07:00–08:00.
The computed water temperature is around 61 °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
Cloudy · feels like +55°
The day is 2 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 data. 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.
