Dry fly question
I hit a spring creek yesterday and I'm not much of a dry fly guy (yet). But I tried a few and noticed some odd trout behavior.
I tied on a light cahill. I didn't see any hatches but there were some rises to light colored insects (coulda just been plant matter) on the water.
The trout ignored the fly. Baitfish would hit and sink it. The trout would start to follow the fly as I reeled it in or it began to drag heavily in the water and then as it would pop up out of the water. Some would travel a good distance to follow the fly.
I gave up thinking the trout saw me at the last minute and turned off.
At the end of the trip I was at a different location, did the same thing. As I was reeling the fly in a dang trout came over and hit it. I caught him!
This whole event just flew in the face of what I believed was paramount to dry fly fishing—a dead drift fly, no drag is needed to take trout.
Just wondering if this behavior means:
(1) I should be fishing a different pattern, maybe swinging wets (which I haven't done)?
(2) Were the flies looking for emergers?
Should I just throw out the book on dry fly dead drifting lessons?
