With the salmon run not working out the way I would like I have been fishing for trout more. This is a very simple fly to make and you'll have to take my word that the combination works very well.
Hook: Tiemco 200R size 4 here
Tag & Rib: Embossed copper tinsel
Body: Olive or brown floss, I use a strand of each. Some turn out olive, some brown.
Thorax: In front of floss and under wing; dubbed gray opossum
Hackle: This fly has blue eared pheasant but ringneck or partridge / grouse will do fine.
Wing: Bronzed mallard tied flat
I took that fly to Carpenter Lake yesterday and fished with it. It caught three rainbow trout and one land locked silver salmon. None of the fish were really big ones but I had never used the fly in still water before and wanted to see if I could get a big trout to take it. The lake is very clear so the fish had a good look at the fly. I wished that I had done better but the other fishermen I talked to had caught nothing using dry fly, so I guess it was a good day.
The hook should be a little smaller for still water I think.
