Fishing Forecast for Larson Lake

A multi-factor outlook built from Larson Lake's measured water quality — clarity, trophic state, depth, and water-body type — combined with each species' biology, seasonal patterns, and today's live weather. It flags spawn timing, where the fish hold, and the techniques that fit this lake's water, not just the moon.

Northern Pike

Game FishSummerSummer pattern

Fair

~70°F est.

Larson Lake runs 21 ft of clarity and grades B for water quality — so finesse presentations and natural colors on light line tend to out-fish reaction baits.

Because Larson Lake averages 21 ft of visibility (clear), so finesse presentations and natural colors on light line tend to out-fish reaction baits.
Its oligotrophic nutrient level puts the summer weedline near 15–20 ft — that edge is the high-percentage zone to hold northern pike through the warm months.
With a max depth of 177 ft, Larson Lake is deep enough to stratify in summer, so coldwater fish hold near the thermocline while warmwater fish stay above it.

Methodology

How this forecast works

A plain solunar table only knows the moon. The LakeQuality Fishing Forecast starts there and adds what actually decides where and how fish bite on Larson Lake — factors we measure rather than guess:

Water clarity — Larson Lake's Secchi reading flips the playbook between clear-water finesse and stained-water reaction baits, and sets the low-light bite window.
Trophic state & depth — nutrient level and max depth set the summer weedline and whether the lake stratifies, which tells you how deep to fish.
Water-body type — natural lake vs. reservoir changes the structure that holds fish.
Species & season — each species' spawn-temperature window and seasonal movements, matched to the lake's estimated water temperature.
Sun & moon — the solunar major/minor periods and dawn/dusk twilight in the calendar below.

The species outlook is a transparent heuristic weighting of these established factors, and it now also factors in today's live conditions — wind, cloud cover, and the barometric (pressure) trend, recomputed for the current day. It's not a validated catch predictor, and water temperature is still an estimate from season and latitude unless a recent USGS gauge reading exists. It's the analysis a solunar table can't do, grounded in Larson Lake's real, measured water quality.

How to read the calendar

Major periods (≈2 hours) are centered on lunar transit (when the moon is highest in the sky) and lunar opposition (when the moon is directly underfoot). These are typically the strongest feeding windows.

Minor periods (≈1 hour) are centered on moonrise and moonset. They're secondary windows that often produce well — especially when they coincide with sunrise or sunset.

Day rating combines moon phase (peak near new and full moons, when lunar gravity is strongest) with the overlap of major periods and the dawn/dusk twilight. A 4–5 star day stacks all three.

At Larson Lake (lat 47.77°N), the longest day of the year is around June 21 with 16h 1m of daylight. The shortest is around December 21 with 8h 24m. Plan summer trips around the early-morning bite (as early as 5:00 AM) and the long evening window before sunset.

Frequently asked questions

What makes this better than a solunar fishing table for Larson Lake?

A solunar table only uses the moon. The LakeQuality Fishing Forecast adds Larson Lake's measured water quality — its clear water, trophic state, depth, and water-body type — matched to each species' spawn window and seasonal movements. That measured data drives where the fish hold and which techniques fit this lake's water, then the solunar calendar below adds the sun/moon timing. It's a transparent, multi-factor outlook, not a validated catch guarantee.

What is the best time to fish Larson Lake today?

Today's solunar calendar for Larson Lake (lat 47.77, lon -93.41) shows sunrise at 5:58 AM and sunset at 8:40 PM. The strongest fishing windows are around major solunar periods at 6:44 PM–8:44 PM and 7:14 AM–9:14 AM, plus the 30-90 minutes around dawn and dusk.

What does the moon phase mean for fishing Larson Lake?

Solunar theory holds that fish activity peaks during major periods (when the moon is overhead or directly underfoot) and minor periods (moonrise and moonset). Fish feeding tends to intensify during the days surrounding the new moon and full moon, when lunar gravity is strongest. Today's moon at Larson Lake is Waning Crescent (32% illuminated).

When are the longest and shortest days at Larson Lake?

At Larson Lake's latitude (47.77°N), the longest day of the year is around June 21 with about 16h 1m of daylight. The shortest day is around December 21 with about 8h 24m of daylight. Sunrise and sunset shift by roughly 6 hours between solstices.

Are major or minor solunar periods more important?

Major periods (about 2 hours, centered on lunar transit and lunar opposition) are generally considered the strongest feeding windows. Minor periods (about 1 hour, centered on moonrise and moonset) are secondary but still productive — especially when they overlap with sunrise or sunset.
