It is in the fall, however, that the big browns become more aggressive as they prepare for the spawn. The best way to get in on the action is to float the river. For fall flyfishing it's hard to beat caddis pattern dries or Gold-Ribbed Hare's Ear nymphs and small Woolly Buggers. Spin-fishermen toss small spinners or spoons. Only artificial lures are allowed and all rainbows must be released. The brown trout limit is five, only one of which may be over 18 inches.
