Now your fly is just below the surface and directly downstream. Let it hang there for at least 10 seconds. Now the lift--simply lift your rod tip a few inches. This brings the fly closer to the surface and the trout thinks it is emerging. Now allow the rod tip to drop back down for a few seconds more. Now lift again. If you are a purist, rather than lifting the rod, you can slowly strip a few inches and accomplish the same thing. I would encourage you though to avoid the temptation to recast every time your fly reaches the end of a drift and instead try a lift. You will be surprised how many times you will get a strike. SEE DIAGRAM TO THE RIGHT ABOVE. I do this several times at the end of each drift.
PS-I have also found that even if I get a nibble, I can frequently leave the fly in place and lift again drawing another hit. I believe this is because the fish frequently hits “short” and does not get stung by the hook, so they are frequently ready to try again.
Good luck. If you have questions or comments, please post a comment or email me directly.
