Flows are dropping and some spots are beginning to be fishable on foot. Crossing Rock Creek, the Rosebuds or the Stillwater is impossible, so be content with the water on your side of the river. The bite is good on both sides!
Fish are looking up for Stimulators, PMX, Chubbies, etc. Yellow is the best color. PMD’s are around on the Stillwater and fish are eating them in flat spots and along banks.
Dropper flies are deadly. Use a long dropper line because the flows are still high and fast. Two to three feet, depending on depth and speed. Prince, pheasant tail and Montana prince are getting hammered.
The Yellowstone is marginal right now. People are floating it and catching fish nymphing deep. Throw something big and ugly with rubber legs. Streamer fishing is fair to slow. The water is still pretty dirty.
The high mountain lakes have turned on. Try a black or olive bugger with a prince trailing it. A size 16 parachute Adams is a good choice for dry fly fishing. Black ants are always a winner.
