Every FishCast call is built from live USGS gauge readings, Open-Meteo weather and pressure data, state Fish & Game regulations, and seasonal hatch and pattern signals. The score is a weighted blend of flow, water temp, weather window, dawn-to-dusk light, clarity, seasonality, and a smaller nudge from barometric pressure.
