    What's working on Cub River

    1. 01Blue-Winged Olives (BWOs) and Pale Morning Duns (PMDs) are the most prominent hatches you'll encounter in October, particularly on cloudier days.
    2. 02The Cub River should be seeing the tail end of the substantial October Caddis hatch, making adults a viable target for rising trout.
    3. 03Midges are a year-round staple and become increasingly important as water temperatures cool.
    4. 04Fall is spawning season for some trout species, so egg patterns will also be highly effective for opportunistic feeders.
    5. 05Focus your efforts on the deeper runs, current seams, and the heads and tails of pools where trout tend to congregate in the cooler fall water. Look for slower, calmer pockets for rising fish during hatch windows. Access near Willow Flats Campground typically offers good walking access to prime fishing spots.
    6. 06With potentially lower and clearer fall flows, focus on a stealthy approach. Employ long leaders and fine tippets, especially when fishing dry flies or emergers to the more selective Cutthroat and Rainbow Trout. For nymphs and streamers, dead-drift them through likely holding water or use a slow, subtle retrieve to imitate lethargic prey.
