The Dexheimer Sedge originates many years ago in the Savona area. A Mr. Dexheimer tied the fly for Tunkwa and Leighton Lakes. While he called it a sedge, it may in fact be more of a shrimp imitation of which both Tunkwa and Leighton have in abundance! Regardless of the feeding Tunkwa rainbow opinions, I can vouch for the success of this fly.
An Australian relative of my hunting partner, Ben Hanson, who at the time lived in Kamloops, very much wanted to catch some of BCs large trout. Morris was not concerned that it was late August when many Kamloops area lakes are still in the doldrums. I suggested that we try Tunkwa Lake for a bit of fly fishing and set up Morris with a slow sink wet line. A dexheimer sedge was fixed to his leader and off we rowed in Ben's car-top boat. The fishing gods must have smiled on us because in spite of a very warm late summer afternoon, a good 3 pound Tunkwa rainbow savagely hit the dexheimer! A new fisherman often will lose such a heavy prize but not Morris as he succeeded in boating the trout! It certainly gave the Dexheimer Sedge a vote of confidence in my mind although I cannot remember how Morris managed to solve the problem of getting the fish back to Australia!
Start by attaching a single strand of peacock herl to the hook shank. Then wind the light green phentex or wool from the hook bend to hook eye. Follow this with spaced turns of the peacock herl to form the rib. At this point, the use of invisible mending thread becomes extremely useful because you can back-wrap the thread hook eye to bend and back again to protect the ribbing against the slashing strikes of big trout! Invisible thread does not distort the body and without this back-wrap, I have found that the peacock herl ribbing will usually be torn apart with the first strike. Now form a throat hackle using a soft brown hackle feather. The final step is to tie in the wing with a whole brown mallard breast feather. Peel enough of the fibers away so that the wing lays flat about the same length as the hook. For those duck hunters out there, look for the brown breast feathers that are white tipped as this does seem to make a difference in fly effectiveness. Tie off, cement and you have finished an interesting Tunkwa Lake fly, the Dexheimer Sedge!
