At some point it stops being luck.

We’re also starting to see PMDs show up. Keep an eye on tomorrow’s conditions report—we may be talking more about those.

The Upper Poudre is shaking off runoff and coming into its prime early-summer form. Flows are settling, insect activity is ramping up, and fish are becoming increasingly willing to feed on the surface as the river finds its seasonal rhythm.
We’re finding fish on dry dropper rigs, and caddis and stonefly activity is building and fish are starting to look up more consistently.
What we’re fishing this week:
• 12 Thingymarob
• 16 Electro Penguin
• 14 EC Caddis
Start high. Cover water. Keep an eye on the caddis windows.
See you out there.

1 Fly We Trust This Week: •12 Thingymarob
Some flies make sense.
The Thingymarob isn’t one of them.
It doesn’t match much. It doesn’t look like much. Yet somehow it keeps finding fish.
High water. Deep seams. Pocket water.
We quit asking why a long time ago.
Don’t ask questions.
Just fish it.

Here’s what we’re reaching for this week:
• 14 EC Caddis
• 16 Electro Penguin
• 12 Thingymarob
• 18 BWO Cripple

1 Fly We Trust: •16 Electro Penguin
On most days on the Poudre, this fly earns its place below a •12 Thingamabob as one of our most reliable droppers.
It sinks quickly, fishes clean, and continues producing when conditions shift.
The Thingymarob grabs the attention.
The Electro Penguin seals the deal.
Available only at .
See you out there.
