This is a seasonal guide compiled from long-run Rogue River hatch patterns, last reviewed May 2026. Exact timing shifts every year with water temperature and flow — a cold spring pushes the salmonflies late, a warm one pulls the caddis early. Treat the months as a window, not a date, and confirm against live water temps and recent reports before you commit to a pattern.
