CURRENT BIG THOMPSON RIVER FLOWS
The tailwater below Lake Estes is fishing well, with trout actively feeding on small subsurface patterns. Expect technical fishing with selective fish due to clear water and pressure.
Midge and Blue-Winged Olive activity is steady, especially during midday windows when temperatures rise.
You’ll find fish holding in:
- Slower seams
- Deeper runs
- Soft edges near structure
Fish are spread out, so covering water methodically is key.
Big Thompson Canyon
Fishing in the canyon is improving but remains slightly more variable.
- Mixed conditions depending on sun exposure
- Some cold water and shaded ice still lingering
- Best success comes midday into early afternoon
Focus on:
- Pocket water
- Protected seams
- Slower pools
When flows stay stable (around 80–90 cfs), the canyon becomes very productive and ideal for wading.
Rocky Mountain National Park
Fishing is starting to open up but is still limited overall.
- Lower elevation water is becoming fishable
- Moraine Park can produce during warm afternoons
- Most high-elevation water remains partially frozen
Expect:
- Technical fishing
- Light tippet (5x–6x)
- Smaller fish but wild and rewarding
What’s Working
Nymphs (Primary Game)
- Zebra Midge (#20–24)
- Black Beauty (#20–24)
- RS2 (#20–24)
- Pheasant Tail (#18–22)
These smaller patterns are critical right now as fish are keyed in on midges and small mayflies.
Dry Flies (Afternoon Windows)
- Blue-Winged Olive (BWO) (#18–22)
- Midge clusters
Look for rising fish on overcast afternoons when BWOs are active.
Streamers
- Small Woolly Buggers
- Mini sculpin patterns
Best during:
- Cloud cover
- Slightly off-color water
- Early/late in the day
Techniques That Are Producing
Right now, success is less about fly choice and more about execution.
Focus on:
- Fishing deep, slow water
- Maintaining a drag-free drift
- Adjusting weight frequently
Clear water means fish are cautious—presentation matters more than anything.
Guide Tips for Right Now
- Fish later in the day as temps rise
- Use longer leaders and lighter tippet
- Slow down—fish are holding in specific lanes
- Don’t overlook water close to you
Outlook
Fishing will continue to improve as temperatures rise and insect activity increases. Expect:
- More consistent BWO hatches
- Increased fish movement
- Better dry fly opportunities in the coming weeks
The Big Thompson is already fishing well and will only get better as we move toward early summer.
