Mutant Stone action on the surface in the mornings and subsurface in the afternoons with small stonefly nymphs
Conditions
Flows have moderated since mid-August and measured 5,930 cfs at Lorenzo as of August 26, though dam releases were reported at 9,500 cfs—a shift worth noting if you're checking upstream gauges. Light turbidity near the source clears quickly downstream. Mutant Stones are active on the surface in mornings and subsurface in afternoons, with Blue Winged Olives and Mahoganies likely as cooler weather moves in. Overcast skies and stable conditions favor a mix of dries, nymphs, and small streamers.

Techniques
- Fish Mutant Stone dries early while light is low, then switch to small stonefly nymphs subsurface as afternoon wears on
- Smaller streamer patterns have been moving fish, especially during the bright sun
- On sunnier, brighter days use hopper dropper or run a double nymph rig through the deeper water
- When clouds and rain arrive, be ready with BWO and Mahogany patterns and give the streamer rod real time on the water
