Fly Fishing Cache la Poudre River - Poudre Canyon

Overview

The Cache la Poudre flows through a granite canyon west of Fort Collins, with pine-lined banks, willow thickets and rocky slopes beside the channel. Riffles and boulder pockets lead into deeper pools and runs. Brown and rainbow trout use the seams and cover, where short casts and careful mends help a fly drift through broken current.

Canyon Water and Fishing

Snowmelt changes the Poudre’s clarity and current. When the main flow is strong, look for slower margins and sheltered pockets beside boulders rather than reaching across the fastest water. As seasonal water recedes, riffle tails and pool edges become more distinct feeding lanes.

Stonefly and caddis activity provides opportunities through late spring and early summer. Nymphs reach fish below the surface; a dry-dropper can cover a pocket when insects and rising trout are visible. Summer mayfly and midge activity calls for closer attention to the size and drift of the naturals. Terrestrial patterns can work along grassy banks later in summer.

Fall brings midge and mayfly opportunities beneath changing cottonwoods and aspens. Work small nymphs through deeper runs when fish stay down, or follow individual rises along slower seams. Winter ice can narrow the available fishing positions and make banks difficult to negotiate.

Highway 14 follows much of the canyon, but a road beside the river does not make each bank or pullout a fishing entry. Named recreation sites have their own boundaries, and the fishing rules vary along the mainstem.
