About these charts

Each river page shows a 12-row × N-column hatch grid (month × active patterns), live water temp and flow from USGS streamgages, the top 3 fly picks for the current month, and FAQ-style answers to the questions we get asked most.

Hatch timing is hand-curated from regional fly shop calendars and angler logs. Always confirm current regulations with your state authority. If something's off, tell us.
