Flowing through Colorado’s stunning Front Range, the Cache la Poudre River is a rugged, scenic waterway known as Colorado’s only Wild and Scenic River. Beginning high in the Rockies, the river carves its way down through Poudre Canyon, offering anglers a variety of water types—from pocket water and riffles to deep pools and runs. Home to wild brown and rainbow trout, the Cache la Poudre attracts fly fishers of all skill levels. With accessible stretches near Fort Collins, the Poudre provides the rare experience of fishing in a pristine, natural environment just minutes from town.
The Cache La Poudre River offers a tranquil and scenic fly fishing experience during the winter months, with its picturesque canyons and reliable trout activity. Flows are currently 50-80 CFS, running low and crystal clear, making for technical fishing conditions. Water temperatures range from 34-38°F, with trout holding in deeper pools and slow-moving runs. The Poudre’s wild browns and rainbows are active, primarily feeding on midges and small nymphs.
Late morning to mid-afternoon is the best time to hit the water, as sunlight slightly warms the stream and triggers feeding activity. Nymphing is the most productive approach, but careful presentations with small streamers can entice larger trout. With minimal crowds and stunning winter landscapes, the Poudre remains a winter angler’s dream.
| Month | Primary Hatches | Effective Patterns |
|---|---|---|
| December | Midges | Zebra Midge (#20-24), Black Beauty (#20-24) |
| January | Midges | WD-40 (#20-24), Miracle Midge (#20-24) |
| February | Midges, Blue Wing Olives | Blue Wing Olive (#20-22), Griffith’s Gnat (#20-24) |
Seasonal Tip
Focus on the slower, deeper sections of the river where trout are holding during the cold months. A stealthy approach is essential due to the crystal-clear water.
Dry Fly
Midday midge hatches can bring trout to the surface. Use small patterns like Griffith’s Gnats for subtle rises in calmer sections.
Nymphing
A two-fly nymph rig with a Zebra Midge and a Black Beauty is highly effective. Add weight to get flies deep in slower water.
Streamer Fishing
Fish streamers like Black Woolly Buggers slowly along seams and near structure for the best chance at larger trout.
Most of the Cache La Poudre River features public access along Highway 14, though some areas are private. Be sure to respect property boundaries and adhere to catch-and-release practices to preserve the fishery.
