One of my most productive patterns for smaller streams out west such as high elevation cutthroat streams is a variation on the Copper John. I call it the Mustard John. The fly is also extremely successful on rivers like the Gunnison during Yellow Sally times. I'll always fondly remember fishing the Gunnison River immediately below the NP visitor center for 2-3 hours and catching trout after trout. Most of them were browns in the 14-18" range with one or two pushing 19" and a beautiful rainbow trout thrown in for good measure. All fish came on the Mustard John.
I'm currently preparing for a Smokies adventure this next weekend and was tying a few flies last night. It occurred to me that some of you may enjoy using this fly so without further discourse, I give you.........the Mustard John!!!
Hook: TMC 5262 #14

Thread: 8/0 Yellow and Black
Tail: Brown Biots

Tie it the same as you would a regular Copper John, just using the different colors mentioned above. For a good tutorial on tying the Copper John, refer to this page on Charlie's Fly Box. If you don't already tie and fish Copper Johns, I highly recommend that you add them to your arsenal immediately. Don't hesitate to experiment with colors. Other proven colors to try are red and green but don't let yourself be limited.
FISHING REPORT AND SYNOPSIS: 5/22/2017
Fishing is good to excellent across the area. The Caney Fork River continues to shine on both high and low water. In the Smokies, strong hatches have been keeping fish looking up.
Yesterday, Blue-winged Olives hatched for hours during the light rain and drizzle. Fish were looking up but also took nymphs well. Streamers were moving some quality fish as well. The summer hatches are well under way now. Expect Golden and Little Yellow stoneflies and Isonychia (Slate Drake) mayflies. Light Cahills and Sulfurs have been around as well.
The Caney Fork River continues to fish anywhere from good to great on high water streamer floats. Anyone who wants to target trout with streamers will find this to be exciting fishing. Low water is becoming more and more likely, and if that trend continues we will see some great low water floats. The fish are hungry and we are going into some of the best fishing months on this fine tailwater.
Cumberland Plateau smallmouth streams are rounding into fine shape now. Rain will bump flows up again, but in between the fish are hungry and willing to hammer a fly! Musky floats are about over for the year unless we get more rain.
