    Great color pop under bright light. The bead gets it down quickly and holds up in current.
  • Dry-Dropper Combo: Chubby Chernobyl + Perdigon (#14 + #18)
    Floaty up top, tactical down low. Ideal in Clear Creek and Bear Creek.
  • Terrestrial: Black Ant or Hi-Vis Beetle (#16)
    Especially effective mid-day when shade lines get active.
  • Streamer: Thin Mint Bugger (#10)
    Best in the first hour of light or during sudden cloud cover. Slow swing near cut banks.

 

 

 


Pro Tips for the Week

1. Get There Early
By 10:30 AM, most spots start getting foot traffic or wind. Early risers will get the best water and the most aggressive fish.

2. Drift Matters More Than Fly Choice
Even the best fly won’t eat if it's dragging. Focus on angles and current seams.

3. Go Small and Natural
Especially in Bear Creek and Boulder Creek, fish are tight-lipped unless you size down and stay subtle.

4. Stay Low
These fish are spooky right now. Wear muted colors and approach from downstream whenever possible.

5. Clouds = Opportunity
If a storm rolls in or the clouds build, switch to a bugger or soft hackle and cover water quickly.


FAQ: Fly Fishing Near Denver This Week

1. What’s fishing the best right now?
South Boulder Creek is fishing best—steady flows, cold water, and active fish on dries and droppers.

2. Are dry flies producing yet?
Yes. Caddis, PMDs, and ants are all seeing surface eats, especially mid-morning and near shadows.

3. What’s the best all-around setup?
A dry-dropper rig: Chubby on top, Perdigon or Rainbow Warrior underneath. Versatile and productive everywhere this week.

4. Is Deckers worth fishing right now?
Yes—if you're willing to fish early or late. Midday is a grind.

5. What’s the water clarity like?
Most creeks are running clear to lightly stained—especially good early in the day before runoff snowmelt hits.

6. Do I need to change flies often?
Only if your drift is clean and you’re getting no takes. Start with proven patterns and adjust your depth first.
