With the September new moon this year comes some beautiful weather and autumn chances to get out and enjoy the extended dry fly season on the Bow River. While the sun is shining, hopper/dropper remains our go-to rig, with smaller hoppers and beetles up top and flashy stuff beneath. Some fish are rising on small mayflies and caddis throughout the day. You can find them if you look for them. October caddis are making an early appearance, especially in the city. We are also still seeing some tricos as well as the start of the BWO hatches. As we head into fall, we should see some cloudy, rainy days and more good BWO hatches. Be ready with some smaller mayflies and lighter tippet for those opportunities. Don't be afraid to go small with your hook size.
Fish are just starting to key in on backswimmers so popular patterns like pheasant tails and prince nymphs are hot. Some streamer action can be found when fish aren't looking up. Try fishing a backswimmer or boatman in tandem with your streamer.
There are some ongoing fish population surveys happening this month, with electroshocking happening on predetermined dates.
Launch update: Ogden boat launch is upgraded and open for use. There's not a lot of space in the water at this launch for boat staging, so be respectful and patient if this launch is busy.
Flies to try:
Nymphs: Pheasant Tail, Bead Head Prince Nymph, Ultimate Water Boatman, Lightning Bug, other boatman and backswimmer patterns
Dries: White Cloud Hopper, KB's Hop Zone, black and cinnamon ants, Black Humpy, and on cloudy days, Booty's DL Cripple BWO or Klinkhammer BWO
Streamers: White Dungeons, Kreelex Minnows, Late Night with Wanda and other flashy streamers to induce a predatory grab.
