Bow River Report

Just a reminder Rainbows are spawning, so watch your step!

With the fluctuation in the river levels, the past week has been a bit of grind. The BWO’s are still heatching and we are starting to see some Caddis hatches, but they fish don't seem to be looking up yet. Skwala’s are still hatching and fishing the nymph forms of those bugs has also been productive. If you are willing to streamer fish and pull rock snot off your fly every other cast, you have a chance of running into some big predatory browns right now. We have had lots of reports of Rainbow trout on Redds, so be mindful where you are walking, keep an eye out for round spots of gravel that are clean compared to the rest of the stream. If you see spawning fish I urge you to leave them be.

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:
  • Baetis and Blue Winged Olives (sizes 14-18)
  • Caddis Nmphs (size 12-16)
  • San Juan Worms
  • Small leeches
  • Bloodworms
  • Black Copper John
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:
  • Blue Winged Olive adults or emegers
  • 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 deep bends, structure, and winter holding water
  • Slow, deliberate retrieves are key
Spring fishing on the Bow River can be technical but rewarding. While peak dry-fly fishing typically occurs from mid-May through October, spring anglers who focus on subsurface techniques can still find consistent success.

Safety Considerations:

  • Dress appropriately for it may not be cold weather wise, but prolonged wading can wear on you.
  • 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.
