LakeGrade AI Fishing Forecast
A fishing forecast that reads each lake's measured water quality — clarity, trophic state, depth, and water-body type — together with species biology and solunar timing. It predicts the spawn phase, a seasonal outlook, where the fish hold, and the techniques that fit that lake's water. Something a moon-only solunar table can't do.

What makes ours better than a solunar table
Solunar tables suggest the best days and times purely from the moon. That influences fish, but it ignores the factors that matter more — and that we actually measure:
- Water clarity decides low-light timing and finesse vs. reaction baits
- Trophic state & depth set the summer weedline and thermocline
- Natural lake vs. reservoir changes the structure fish relate to
- Species & season — spawn windows and seasonal movements
- Sun & moon — solunar major/minor periods and dawn/dusk
How the AI forecast works
Our engine reads the same water-quality data behind each lake's A–F grade, matches it to each species' documented biology, and layers on season and solunar timing to produce a per-lake, per-species outlook.
It's a transparent, multi-factor heuristic — we show every factor it weighs. It is not a live weather feed and not a guaranteed catch predictor; water temperature is estimated where no gauge exists. Grounded in real, measured data, not guesswork.

Frequently Asked Questions
What is the LakeGrade AI Fishing Forecast?
It's an AI-powered fishing forecast that analyzes each lake's measured water quality — clarity (Secchi), trophic state, depth, and whether it's a natural lake or reservoir — alongside each species' spawn temperature, seasonal movements, and the sun/moon solunar cycle. For any of 7,664 lakes across 13 states it predicts the current spawn phase, a seasonal outlook, where the fish are holding, and the techniques that fit that specific water.
How is this better than a solunar fishing table?
A solunar table only uses the position and phase of the moon. That influences fish, but season, sun, water clarity, water-body type, depth, and each species' biology matter far more. Because LakeGrade already measures the water quality of every lake, the forecast can factor in what a moon-only table can't — for example, a clear lake pushes fish onto low-light windows and finesse baits, while a stained lake rewards vibration and reaction baits. We grade the water; we don't guess it.
Does the forecast use live weather?
Not currently. The forecast is built from stable, measured inputs — the lake's water quality, species biology, season, and solunar timing — so it stays accurate offline and works for every lake. Water temperature is estimated from season and latitude unless a recent USGS gauge reading is available. It is a transparent, multi-factor outlook, not a live weather feed or a guaranteed catch predictor.
Which fish does it cover?
Walleye, largemouth and smallmouth bass, northern pike, muskie, crappie, bluegill, yellow perch, trout, catfish, and more — each with its own spawn window, seasonal depth and structure, and technique guidance conditioned on the lake's measured clarity and trophic state.
