Fishing Yellowstone National Park's famous Slough Creek can be a real test of skill and fly fishing knowledge. The Cutthroat trout are tough to catch and by mid-season have seen most every fly available. Knowing a few key flies and how and when to fish them can make all the difference.
There are a few flies I would not be without on Slough, this is one of them. That's why my buddy Ben named it as such. Anytime you see a fly with a creeks name, and you are going to fish that creek........... You're going to want some of those.
This spinner pattern is my go to pattern for most any mayfly... I just adjust the hook size and colors of materials.
using a size #12-14 dry fly hook with Danville Olive thread, tails formed and a biot at the ready for wrapping...
wrap the thorax with the dubbed thread using more figure 8's and then form the head and double whip finish...
I fish this fly in size #12 during the Green Drake hatch and spinner fall. I fish it greased, 12 inches or so behind a EMT Green Drake Emerger as these spinners are tough to see on the water and the EMT acts as my indicator. It's best fished to slow risers in quieter water. Also, I like to feed them to difficult fish when nothing else seems to work by fishing them as a trailer without floatant as a drowned dun... this usually does the trick.
