How this rating works

Solunar theory says fish feed more when the moon is overhead or underfoot (major periods, about 2 hours) and around moonrise and moonset (minor periods, about 1 hour). On a lake or river there is no tide, so instead of tide changes we score the local conditions anglers watch: the barometric pressure trend, the wind, whether the lake level is steady, and the water temperature where it is measured.

1–3 poor · 4–5 fair · 6–7 good · 8–10 excellent. Pressure and wind are the NOAA National Weather Service hourly forecast for this spot; the level/flow trend is the latest 24 hours of readings on this page. Days 2–7 score sun, moon, forecast pressure and forecast wind only (level and water temperature aren’t forecast). Solunar times are a rule of thumb, not a guarantee.

Solunar periods calculated for 39.66, -99.13 (moon times from astronomical equations, Kirwin Lake local time).
