Species context
Why this score
Excellent (88/100) for Yellow Bullhead: water is estimated at 79.6°F, below Yellow Bullhead's 82-84°F optimal range. Best window: Night — boosts feeding activity by about 50%, one of their peak feeding windows. That hour also overlaps a major solunar period. 30.07 inHg and falling pressure modeled flat — no change from this fish's baseline. Calm (0-5 mph) wind modeled flat — no change from this fish's baseline.
What's driving the 8 PM score
Water temperature (79.6°F estimated) is doing the most for this score. The score gives up the most on water temperature — 79.6°F estimated, about 7.2 points below its best.

Water temperature: 79.6°F estimated
37.8 of 45 pts
Optimal range 82-84°F
Well supportedWater temperature governs a cold-blooded fish's metabolism, so it is the largest term in the model (Christie & Regier 1988). The figure is a thermal-lag estimate built from forecast air temperature and the time of year — not a sensor reading, and not this lake's actual measured water.
Light window: Night
30 of 30 pts
Boosts feeding activity by about 50%
Well supportedLow-light feeding windows are the strongest timing signal inside a single day. How much each window is worth is this species' own cited response, sourced in its model file, not a generic curve.
Solunar period: Major period
5 of 5 pts
Not supported by testingPeer-reviewed testing of North American freshwater fisheries found no significant relationship between solunar values, lunar phase or lunar illumination and catch rates (SN Applied Sciences, 2023) — air temperature predicted catch better than any solunar table tested. It is shown because anglers expect it, and it is shown separately so you can discount it. The owner reviewed this evidence and demoted its weight accordingly.
Barometric pressure: Falling
10 of 10 pts
Modeled flat — no change from this fish's baseline
ContestedThe barometric effect is real to most anglers but small and contested in the literature — several of the species studies cited in this model report null results — so it carries one of the smallest weights here.
Wind: Calm (0-5 mph)
9.5 of 10 pts
Modeled flat — no change from this fish's baseline
Moderately supportedWind stacks forage on windward structure, but both the size and the direction of the effect depend on the species and the water, so it carries a modest weight.
Then the whole score is scaled
Season: Summer — ×1.00 (100% of the ungated score)
How catchable Yellow Bullhead are at this point in the year. This scales the whole score rather than competing with the factors above — a fish that is dormant this time of year cannot score well no matter how good the hour looks.
Weather front: No clear front — ×1.00 (100% of the ungated score)
A multi-hour frontal pattern read from the day's forecast trajectory. No front is classified today, so this changes nothing and the single-reading pressure factor above does its normal job.
Those five factors add up to 92.3 of 100 points, and the two multipliers above take that to 92. The weights are tuning constants — solunar's was demoted after peer-reviewed testing found no predictive effect (#456), and the rest remain under owner review — shown here rather than hidden so you can weigh them against your own judgement.
What this score does not know
- Water clarity. We have no source for it and do not estimate it.
- Measured water temperature. The figure in the breakdown is a model over forecast air temperature, not a reading from a buoy or a probe.
- Baitfish and forage activity.
- How much fishing pressure this water has had.
- Where the fish actually are. Depth bands are the species' published seasonal ranges, not an observation of this lake.
- What anyone actually caught. No catch reports feed this score.
Conditions read from the National Weather Service as of Oct 5, 2026 at 2:42 PM EDT. Solunar periods and sun/moon times are computed, not fetched.
When best caught
It's currently summer. Yellow Bullhead typically hold 2-10 ft deep this time of year — at an estimated 79.6°F, this looks like a slower time of year to target them, since water temp is outside their optimal range.
Current depth
2-10 ft
This is the seasonal depth band from the species model — relative to this species' typical behavior, not this lake's actual structure. True depth relative to this lake's bottom contours needs lake bathymetry (tracked in issue #175).
