The usual nymphs and wooly buggers should work, muddler minnows. Small brown and black dries work on brookies aswell. As for salmon flies the classics such as the blue charm, thunder & lighting, with both the black moose hair wing and white wing. The most popular dryfly for salmon in NF is the orange bug tied with a tail on each end (which is called a bomber). These flies worked for me when I lived in NF, brookies are pretty easy to catch, salmon on the other hand can be a little tricky.
