The Cache la Poudre doesn’t need to shout - it whispers. October here is quiet, golden, and perfectly balanced between crisp mornings and blue-winged afternoons. The crowds are gone, the trout are wild, and the water sounds like someone exhaling after a long summer.
The Poudre is in that perfect shoulder season groove right now. Flows have leveled out, clarity is sharp, and the crowds have all but disappeared. Cold nights and crisp mornings make for quiet water early, but by late morning, trout start sliding out of cover and feeding steadily on midges and BWOs.
This week is all about small flies, long leaders, and patience. The canyon feels wide open, the cottonwoods are turning, and the fish are happy if you keep your steps light.

Pro Rig of the Week
Guide setup: Run a 9-foot 5x leader with a #18 Guide’s Choice Hare’s Ear and a #20 Black Beauty 18 inches below on 6x tippet. Add one small split shot above the lead fly and keep the indicator minimal—target seams along cutbanks and deep pocket water below boulders. Fish short and accurately — the current moves fast, and trout won’t chase far.
