Yellowstone River Report 8/7/2017
Clarity has improved. Dark colored buggers, as well as the Grinch dead, drifted under an indicator has been a good producer. Rubber leg nymphs like a girdle bug drifted along the bank water and riffles have been working too. Fish it on a long dropper off of a big dry like a Chubby Chernobyl. Other rubber leg patterns or a prince nymph in a size 10-14 are good choices too.
There are plenty of hoppers on the banks in the afternoon and fish are starting to hit them. Start throwing hopper and large dry fly patterns like Chubby Chernobyls, Jack Cabe, PMXs, Yeti Hoppers, Fat Franks and Yellowstoner Chubbys in the afternoon. Use a dropper nymph too, but if there’s no action on it just go with the single hopper pattern. Try giving them a twitch every now and then, particularly when drifting calmer water.
Also, as the water warms this time of year, look to fish water other than the banks too. If getting out early to beat the heat, try throwing streamers early.
