Stoneflies are making an appearance on the Yellowstone and Stillwater rivers. The shucks are everywhere on the rocks at waterline. Browns on the Stillwater were hammering them in the bright sunshine earlier this week.
Small caddis and smaller grey mayflies are also popping on the Stillwater and Rock Creek. The caddis are hatching a few at a time, but good numbers can be seen laying eggs. Fish are keying on them in foam lines, so keep you eyes peeled for risers.
The Stillwater and Rock Creek are dropping fast. Wade fishing is getting better and better. Crossing is a challenge on the Stilly. Rock Creek can be crossed in certain places, but choose your spot carefully.
The Yellowstone is clearing. It hasn’t reached optimum condition yet. Some fish are on the big stonefly dry, but nymphs are taking the most fish. Hoppers are around and fish are eating them on windy days. This should only get better as the water comes down and clears.
Here’s your list of must have flies:
Yellowstoner Chubby, brown, #8 (Remember that our stoneflies are not orange)
Parachute Adams, #16
Elk Hair Caddis, black body, #16. I tie mine with no hackle and a little antron trailer. Good for both emerging or egg laying caddis. The traditional dressing is working, but the antron really seems to seal the deal.
Drop a beadhead Prince, Pheasant Tail, Montana Prince or any other dark pattern off the big dry to maximize your catch.
