A state fisheries survey records Smallmouth Bass in Lake Lyndon B Johnson.
Species context
Why this score
Good (77/100) for Smallmouth Bass: water is estimated at 67°F, below Smallmouth Bass's 70-80°F optimal range. Best window: Dawn — boosts feeding activity by about 30%, one of their peak feeding windows. That hour falls outside any solunar period. 30.04 inHg and stable pressure modeled flat — no change from this fish's baseline. Calm (0-5 mph) wind modeled about 10% below this fish's baseline.
What's driving the 7 AM score
Water temperature (67°F estimated) is doing the most for this score, even at about 9 points below its best. Of the other factors, it gives up the most on solunar period — outside any period, about 3.5 points below its best.

Water temperature: 67°F estimated
36 of 45 pts
Optimal range 70-80°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: Dawn
30 of 30 pts
Boosts feeding activity by about 30%
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: Outside any period
1.5 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. We reviewed this evidence and cut its weight accordingly.
Barometric pressure: Stable
9.5 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)
7.8 of 10 pts
Modeled about 10% below 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: Fall — ×1.00 (100% of the ungated score)
How catchable Smallmouth Bass 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 5 factors add up to 84.8 of 100 points, and the two multipliers above take that to 85. The weights are tuning constants — solunar's was cut after peer-reviewed testing found no predictive effect, and the others are adjusted as we validate them — 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 Nov 13, 2026 at 2:17 AM CST. Solunar periods and sun/moon times are computed, not fetched.
When best caught
It's currently fall. Smallmouth Bass typically hold 20-40 ft deep this time of year — at an estimated 67°F, this looks like a workable time of year to target them: water temp is outside their optimal range, but other conditions are lifting the score.
Current depth
20-40 ft
This is the seasonal depth band from the species model, based on this species' typical behavior, not this lake's actual structure.
