Bow River Report

Brown Trout start spawning this time of year, be mindful of where you are wading and angling!

The fishing on the Bow really slowed down with the overnight temps dropping. Blue Winged Olives and Midge make up the bulk of what’s hatching right now, so if you see any rising fish later in the day it is likely eating one of those. That being said you can still get some eats on terrestrial patterns this late in the year, just keep them small. It’s sounding like the most effective rig on the bow right now is a either a leech or worm paired with a small Baetis imitation like a Hare’s Ear, Pheasant Tail or Prince Nymph. Another great option to fish in the later season is a small streamer with a Water Boatman pattern tied in behind it. You’ll want to swing that right into shore and fish tend to eat that Boatman pattern very close to shore. Keep in mind that the Brown trout are starting their spawning season. If you see fish just hanging out in the open, or in shallow water with clear patches of gravel, it’s recommended to leave them alone and let them spawn. Keep an eye out where you are wading as well, you don’t want to go stomping around on those fresh spawning beds. The forecast for the coming looks great for fishing, good luck if you head out this weekend!

How to attack the river:

Nymphing (Most Productive):

Nymphing is always a great way to fish on those hot days when the fish don't want to rise.
Where to Focus:
  • Deflections and pools close to shore 
  • Seams and inside bends and corners
  • Deep drop offs near rip rap banks
Patterns producing the most right now:
  • Bloom's Tungdart (sizes 14-18)
  • Copper John (size 12-18)
  • San Juan Worms
  • Small leeches
  • Jiggy Baetis (sizes 16-18)
  • Dee's Water Boatman (sizes 14-18)
Both indicator nymphing and Euro nymphing setups are effective. Depth control is critical — don’t hesitate to add weight.

Streamer Fishing:

Streamers can produce fish, especially larger browns, you can even try bottom bouncing a small leech. Try changing your presentation style and speed till you find what's working, some fish are looking for a chase.

Dry Flies

Dry fly eats seem to mostly be happening in the morning and evenings
Best Bet:
  • Juicy Hopper (sizes 8-12)
  • Caddis adults (size 12-16)
  • Hi-Viz BWO (14-18)
  • Hi-Viz Cinnamon Ant (14-18)
It is essential to watch closely for subtle rises during midday, when temperatures typically peak.

Things to remember no matter the fishing technique:

  • Use sink tips or heavily weighted flies
  • Focus on deflcetions and slack water close to shore
Run-off fishing on the Bow River can be technical but rewarding. You have to spend a lot fo time searching for fish, but some real big fish can be close inches from shore.

Safety Considerations:

  • Be Sure of your footing, the Bow is pretty slick this year. Felt soles or studded rubber is definitely recommended 
  • Don't forget to wear sun protection at this time of year, though it may not always be hot you can still burn easily being out all day.
