From The River's Edge:
8/5 The Yellowstone is clear and fishing well, set the alarm and get out there early to take advantage of the best fishing. Nymphing with a bugger or girdle bug trailed with a bead had been the most productive, try some of the faster riffles as it seems a lot of fish are in these. Hopper fishing has been the main action on the surface, as the hatches have died down. Fish the hopper tight to the bank, and maybe throw a beadhead dropper a couple of feet below it to increase your odds. Due to the warm water temperatures and river closure at 2, it is best to fish a heavy leader so you can bring the fish in and release them as quickly as possible.

8/5 Spruce Moths! We can't keep this pattern in stock here at the shop. Dry fly fishing has been outstanding in the canyon with spruce moths. If you don't have one try a large tan Elk Hair Caddis or any light color attractor dry fly. If the fish don't want to rise and take your dry fly hang a nymph about two feet below your dry. Don't forget about the YNP section of the Gallatin this time of the year, try a small hopper trailed with a beetle or ant in some of those slower s-turn banks. Due to the warmer temps, the lower reaches of the Gallatin from I-90 to Three Forks is closed to fishing from 2PM til Midnight. To be honest, the river is very mossy down there so I'd recommend giving those fish a break and avoid the lower river all together. Have fun and release fish as quickly as possible, it's hot outside!
