I was wondering if anyone truly understands the techniques behind summer fly fishing. It seems as if the trout look for oxygen and shade, but I am convinced that they mainly would like to be deep and away from the sun where the water is a bit cooler. Yet, they still seem to bite at those surface hoppers, caddis or even adams according to dry fly guys.

I am planning to fish Ramapo, and I am stuck in deciding whether to fish a small creek for little brownies, or to hit a larger one where maybe the fish would lurk in the late summer months. Lateley, the czech nymphs are the only thing working for me. I know my technique is off.... any location suggestions (not speciffic, just an idea of obstructions to look for) for dry/wet fly fishing in late summer?

Thanks,

Adam
