Few events get fly fishers excited as the rise or roll of a fish, especially when it is in casting range.  This excitement often becomes a disadvantage as fly fisher’s may choose the wrong presentation technique.  Take the time to observe the rise form.  All too often anglers assume that when a rise form occurs it is in response to something on the surface.  Unless something was actually observed being snatched from the surface further investigation is required.  Trout often come up and over when feeding on top gulping both prey and air.  On their way back down into the depths the trout expels all that is not food.  This action leaves a tell tale air bubble at the surface and is why as fly fishers we must wait before setting the hook.

Trout feeding just beneath the surface tend to show their shoulders and dorsal area.  Knowing this makes all the difference when it comes to fly selection.  In most hatch situations trout prey upon what is easiest and insects in the midst of transformation are easy pickings.  The next time you see trout bulging the surface choose a nymph or soft hackle emerger.
