Bringing it back home, the Metolius is fishing quite well, with good hatches of BWO #18 and Cinygmula #14-16 and American Grannom Caddis #14-16 mixed with October Caddis #8-10 and Silver Stripe Sedge #12-14
Think bottom to top approaches for the hatches. Do I have the nymph? do I have the pupa (if it pupates), do I have the adult? Will an emerger or a cripple be important? What about an egg laying stage?
When we are assembling fly selections for technical waters this is the way to do it: Nymph-Pupa (caddis and midges have a pupa stage, mayflies and stones do not), emergers (will that fly be best if it floats or is it also possible to need an emerger that fishes below the surface like a soft hackle can), a cripple (so many mayflies especially end up crippled during the emergence and this provides a helpless meal to a trout), an Adult and a final stage egg layer?
Knowing how to do this makes you a better angler. Set up your boxes like a pro.
Nymphing has been most productive and a good number of fish have been coming to Spanish Nymph, Walts Worms, Olive Perdigons, Bird of Prey October Caddis, Golden Stones and Eggs.
