The explosion of vine maples along the Metolius might be enough reason to fish the Metolius in October but add in the chance of hooking a massive bull trout or a beautifully colored Rainbow and it makes the trip always worth it.
October is a good month to find some nice bows greedily eating off the surface. Blue Wing Olives and Mahogany Duns are two of the more popular hatches at this time but keep an eye out for a late PMD hatch or even a few smaller Drakes. Metolius fish are notorious late sleepers so don’t worry about getting to the river too early for a hatch. Late morning to early evening is prime time in October. Nymphing with the usual suspects will also find fish. Pheasant tails are great in October as are the larger October Caddis nymphs.
Bulls are prowling the river at this time looking for an opportunity to fatten up on the spawning kokanee that are now present. Egg patterns are great at this time of year and will also catch some rainbows. The big bulls are keying into the dying kokanee however and running a large streamer such as the Olive/White Dolly Llama will often make the bulls take notice. Bring the 7 or 8 weight rod to chase bulls and use heavy leader to help prevent breaking off a big fly in the bull’s big mouth.
