Species context

Why this score

Good (73/100) for Yellow Perch: water is estimated at 71.3°F, below Yellow Perch's 72-76°F optimal range. Best window: Daytime — has no measurable effect on feeding activity. That hour also overlaps a major solunar period. 30.23 inHg and rising pressure modeled flat — no change from this fish's baseline. Light (5-10 mph) wind modeled about 15% above this fish's baseline.

What's driving the 11 AM score

Water temperature (71.3°F estimated) is doing the most for this score. The score gives up the most on light window — daytime, about 5.8 points below its best. The whole day is then scaled to 88% for post-cold-front high.

Show the numbers behind this
  1. Water temperature: 71.3°F estimated

    38.1 of 40 pts

    Optimal range 72-76°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.

  2. Light window: Daytime

    19.2 of 25 pts

    Has no measurable effect on feeding activity

    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.

  3. Solunar period: Major period

    15 of 15 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. Its weight is under owner review.

  4. Barometric pressure: Stable (held neutral by the front)

    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.

  5. Wind: Light (5-10 mph)

    10 of 10 pts

    Modeled about 15% above 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 Perch 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: Post-cold-front high — ×0.88 (88% of the ungated score)

A multi-hour frontal pattern read from the day's forecast trajectory. Because a front IS a barometric event, it replaces the single-reading pressure factor above, which is held neutral — the barometer is never counted twice.

Those five factors add up to 92.4 of 100 points, and the two multipliers above take that to 81. The weights are v1 tuning constants under owner review — they are 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 Aug 10, 2026 at 8:48 AM MDT. Solunar periods and sun/moon times are computed, not fetched.

When best caught

It's currently summer. Yellow Perch typically hold 10-25 ft deep this time of year — at an estimated 71.3°F, this looks like a slower time of year to target them, since water temp is outside their optimal range.

Current depth

10-25 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).

Best times

When do yellow perch feed during the day?

Yellow Perch feed most actively at Dawn and Dusk, when activity runs about 30% above the daily average across all four light windows.

  • Dawn1.30x

    Boosts feeding activity by about 30%.

    Has no measurable effect on feeding activity.

  • Dusk1.30x

    Boosts feeding activity by about 30%.

  • Night0.40x

    Suppresses feeding activity by about 60%.

Where to find Yellow Perch right now

Typical Summer depth: 10-25 ft

Yellow Perch feed most actively at Dawn and Dusk, when activity runs about 30% above the daily average across all four light windows.

No depth survey or measurement is on record for Newman Lake, so these bands are the species' published seasonal ranges rather than a reading of this water.
