Let's start with it spawning season for the browns. So if you don't know what redds are stay out of the riffles. If you do use commen sense and let the fish flirt.
Bwo's and midges are the surface game. Make sure you have a good selection of emergers, cripples, and adult patterns. You can nymph hairsears, pheasant tails, caddis, and zebra midges. Typically size 16-22.
