Live conditions for every trout river in the U.S.
Angler Tech pulls real-time USGS streamflow, water temperature, solunar bite windows, and AI fly recommendations into one map — so you know if it's worth driving before you go.
What you get
Live USGS streamflow
Real-time CFS, gauge height, and water temperature for every gauged river in the country — refreshed every few minutes.
Strike Zone forecast
Solunar feeding windows, sun times, and a confidence score that tells you whether today is worth it.
AI Fly Guide
Fly picks tuned to the water temp, hatch calendar, and season for the river you're actually fishing — not a generic top-10 list.
Access & wading safety
State DWR access points and boat ramps mapped, plus wading safety derived from live gauge readings.
