Stable flow out of Palisades Dam (around 9000 cfs) helps keep fishing success stay relatively constant. It’s a bit early in the month for BWOs and mahoganies to be important, so continue presenting bead head nymphs of choice in riffles until rise forms from PMDs and alberts appear in good numbers meaning emerger and dun patterns will become effective. Pitch hopper-dropper combos from boats back toward vegetated banks. While wading around shallows later in the day, look for baitfish concentrating there. This is a tip-off that larger trout will forage on these as sunlight leaves the river. Thus if you are on the river during evenings, streamer patterns become effective when presented near shallows as the sun sets. Patterns in somber colors (olives, browns, and ultra-violet end of the spectrum shades) are best this time of year.
The Jackson Hole One Fly Contest is ongoing along the river. No more than eight boats per section will be participating. So crowding is not an issue. This great event deserves support from all fly-fishers. Go to the Jackson Hole One Fly Contest web site to see details on organization, schedule, and purpose.
