The Cache la Poudre River offers some of the most rugged fly fishing near Fort Collins, and winter pushes it into a lean, honest freestone fishery. Flowing out of the Front Range foothills, the Poudre runs cold, fast, and clear this time of year, rewarding anglers who focus on structure, depth, and timing.

May 19th 2026
The Cache la Poudre is moving into pre-runoff mode. The main Fort Collins USGS monitoring site is active and operated in cooperation with the City of Fort Collins, which makes it the key gauge to check before heading into the canyon.
The Poudre fishes best right now when you treat it like changing pocket water, not a stable tailwater. Early and late morning should offer better clarity and control, while warmer afternoons can bring more bug activity but also more push and stain. The river is also a major recreation corridor through Poudre Canyon, so expect increasing rafting, kayaking, and roadside traffic as spring turns toward summer.

Tips Fly Fishing on the Cache la Poudre
Seasonal Strategy
Fish lower elevations early in the season. As temps rise, more of the river becomes productive.
Dry Fly
Limited but improving. Watch for short BWO windows.
Nymphing
Primary method. Pocket water requires tight drifts and good positioning.
Streamer Fishing
Underrated. Works well in deeper pockets and during lower light.
