Clark’s Stonefly is a great pattern for fly fishing our McKenzie and Willamette Rivers. This is an easy golden stonefly imitation — it only takes Barrett four and a half minutes to tie it. FYI… if you click on the “HQ” button on the player you can watch this in video higher quality if you have a fast internet connection.
Scott Richmond at Westfly has a great article on fishing big dry stonefly patterns:
Generally, a short, heavy tippet–3X or even 2X–will help you cast big, bulky flies more accurately. You also want a strong leader because a few errant flies are going to land in the trees and grass along the riverbank. A heavy leader gives you a better chance of pulling the fly out of the brush.
