Southern Alberta

The Crowsnest:

The Crowsnest is lookin’ pretty juicy right now, water levels are back down and it’s running clear. The Caddis and Mayflies are hatching, and it sounds like some Golden Stones have been spotted here and there. A dry dropper rig would be great for searching for fish right now if you aren’t seeing consistent rising, if you do run into a pod of rising fish, they like long leaders and light tippet down there. Keep your Caddis or PMD’s on the smaller side and you might coax them eat a couple! If you head down, I hope you have a great weekend!

The Oldman:

The Oldman is running clear but still a little high, and water temps are quite low still. This means fish will be more active later in the day when the water warms up a little. I would start the day with a nymph rig for the deeper holes or throw a streamer deep and slow to try and get a hungry bull. As is it warms up you can stitch do a dry dropper rig or go straight dries if you are seeing rising fish. It’s mostly going to be PMD’s in the heat of the day and they also love some Purple Haze down there. Good Luck if you head down this weekend, and report back!



The Strategies that are getting the job done: 

The water is warming up so you will start to see fish more eager to move later in the day, technical stealthy dry fly tactics could get some fish moving. Deep nymphing will stil be the most effective method of chasing fish. 

Nymphing (The High-Percentage Play):

This will be your most productive method. Use a strike indicator or a Euro-nymphing rig.

Patterns: Cheater Belly (#6-10), San Juan Worms in red or pink; and small Pheasant Tails (#14-16), Ryacophia Czech Nymph(#10-14).

Pro Tip: You need to “hit them on the nose.” If you aren’t ticking the bottom occasionally, add more split shot. The trout won’t move far to chase a meal in winter.

Mid-Day Dry Fly Opportunity:

On these warm afternoons, keep an eye out for big bugs on the water, you could see some big eats.

  • Patterns: X Caddis Tan(#16-18), Hi-Viz Parachute PMD (#14-18) Dornan's Water Walker Golden Stone (#8-12) Purple Haze (#14-18)
  • If you see fish rising chances are they are earing Salmon Flies or Caddis. 

Streamers (For the Aggressive Rainbows):

If the wind picks up (common in the Pass), a slow-stripped streamer can trigger a strike.
  • Patterns: Small leeches (black or olive) or Woolly Buggers (#8-12).
  • Pro Tip: Use a sink-tip line and move the fly with very slow, rhythmic pulses rather than fast, erratic strips.

Important Reminders:

  • Regulations: The mainstem from the outlet of Crowsnest Lake to the Cowley Bridge is open all year, but please double-check the 2026 Alberta Guide to ensure no local emergency closures aren't in effect.

Safety Considerations:

  • It's that time of year where the bears start to wake up, I'd bring your bear spray along just to be safe.
  • Make sure you have good footing when wading in cloudy conditions, and don't wade to deep, the current is strong and you could lose your footing.
