Strategy

UPGRADED BACK — SPFS (7/3): flows risen over the past few days to ~295 cfs, clarity improved after the heavy rains, and the fishing has been pretty good this week — dry-fly fishing has improved. Tricos prevalent early mornings; PMDs and caddis in the afternoons. Match the hatch on top, or nymph a girdle bug/stonefly trailed by a smaller mayfly nymph; smaller-diameter tippet and adjusting depth frequently are key. 5/6X fluorocarbon for nymphing; heavier split shot or larger tungsten point flies to get down at these flows. Today (Sun Jul 5) ~80°F canyon, mostly sunny — good all-day window; scattered storms return Tue–Wed. Crowds still up — walk a bit for solitude.
