Modeled from live National Weather Service data as of Oct 27, 2026 at 4:22 AM CDT, plus solunar and sun/moon times computed in-house. This is a computed report, not an eyewitness catch report.
Spruce Lake has no state survey naming Northern Pike. Its presence is an estimate inferred from 8 confirmed lakes within 40 miles — not a record of a catch.

Species context
Why this score
Good (76/100) for Northern Pike: water is estimated at 54.7°F, below Northern Pike's 60-68°F optimal range. Best window: Dusk — boosts feeding activity by about 30%, one of their peak feeding windows. That hour also overlaps a major solunar period. 30.33 inHg and falling 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 1 PM score
Light window (dusk) is doing the most for this score. The score gives up the most on water temperature — 54.7°F estimated, about 15.9 points below its best. The whole day is then scaled to 104% for pre-frontal warm sector.

Water temperature: 54.7°F estimated
29.1 of 45 pts
Optimal range 60-68°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: Dusk
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: 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: 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.
Wind: Light (5-10 mph)
9.6 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: Fall — ×1.00 (100% of the ungated score)
How catchable Northern Pike 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: Pre-frontal warm sector — ×1.04 (104% 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 83.7 of 100 points, and the two multipliers above take that to 87. 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 27, 2026 at 4:22 AM CDT. Solunar periods and sun/moon times are computed, not fetched.
When best caught
It's currently fall. Northern Pike typically hold 8-18 ft deep this time of year — at an estimated 54.7°F, this looks like a slower time of year to target them, since water temp is outside their optimal range.
Current depth
8-18 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).
