Bow River Report

Run-off is officially here, but don’t worry because there are still opportunities to catch some nice fish in some weird places. If do you head down the river you should be bringing some big streamers with dark colours and a pretty heavy sink tip. If you’re not a fan of streamer fishing don’t worry, drifting a dark stonefly or leech along seams close to shore can also produce some nice fish. The nice thing is you don’t have to worry about casting far, but if you are willing to cover ground and make a lot of casts, you’re bound to run into a fish or two. If you don’t feel like fishing a river that looks like a double-double, you can always head out to Lower Kananaskis lake. By the sounds of it hanging a leech or a grey Chironomid under an indicator on the southeast end of the lake has been quite productive. Good luck if you get out this week!

How to attack the river:

Nymphing (Most Productive):

Nymphing continues to be the most effective method this week.
Where to Focus:
  • Deflections pools close to shore
  • Slow seams and inside bends
  • Tailouts below riffles
Patterns producing the most right now:
  • Trout Retriever (sizes 14-18)
  • Cheater Belly (size 12-16)
  • San Juan Worms
  • Small leeches
  • Tungsten Ryacophia Czech Nymph (Sizes 12-14)
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 opportunities are limited but not impossible.
Best Bet:
  • Chubby Chernobyl Purple or Patriot (sizes 6-10)
  • Caddis adults (size 12-16)
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:

  • Watch your step and try to avoid wading too deep, the current is strong right now and it is easy to lose your footing.
  • 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.
