Fishing Report

Report conditions: 88 cfs · — 0.0% 24h · ↓28% median

Flows on the Upper Ruby are running well below median (88 cfs vs 122 cfs normal) but holding steady, and cool morning temps have water fishing clean and clear. With no shop intel specific to the Ruby, lean on the active hatch data: hoppers and ants along grassy banks during the warmer afternoon hours, Yellow Sallies and caddis for a morning dry fly bite, and midges for consistent subsurface action. Low flows mean fish are concentrated in deeper runs and undercuts, so target those areas carefully and consider fishing early to beat afternoon warmth.
