Cache La Poudre River, Colorado
Poudre Canyon — Colorado's only designated Wild and Scenic River
The Cache La Poudre River holds the distinction of being Colorado's only river designated as a National Wild and Scenic River — a recognition of its exceptional natural character, scenic quality, and the historic significance of its canyon corridor west of Fort Collins. The Poudre Canyon has been settled, farmed, and fished since the mid-19th century, and the river's Wild and Scenic designation protects the last free-flowing stretch of the Front Range's primary mountain drainage.
The canyon section — accessible via CO-14 from Fort Collins — provides approximately 50 miles of fishable water through the Roosevelt National Forest, with a variety of character from intimate pocket water in the upper canyon to broader riffle-pool sequences in the lower canyon near Fort Collins. The river's gradient varies considerably: steep, technical pocket water in the upper canyon gives way to more moderate terrain below, creating habitat for wild rainbow and brown trout throughout the accessible length.
The Poudre is the Front Range's answer to the South Platte — a quality wild trout fishery within easy reach of the Fort Collins-Denver metro area (30–90 minutes depending on section). While it doesn't match the South Platte's density of trophy fish, the Poudre offers a more intimate, mountain stream experience with beautiful canyon scenery and less pressure than the better-known fisheries to the south.
Runoff from the Cameron Peak and other watershed areas can color the river through May and into June in high snow years — check USGS flows before making the drive, as the river can be unfishable for weeks following major runoff events. Post-runoff fishing from mid-June through October is consistently excellent.
Lower Canyon — Fort Collins to Rustic
CO-14 provides continuous access from Fort Collins west through the lower canyon. Multiple pull-offs and designated fishing access sites. Most accessible and most pressured section.
Rustic to Mishawaka — Mid Canyon
Better balance of access and solitude. Several campgrounds provide base access. Good summer Caddis and PMD water.
Upper Canyon — Above Poudre Park
Higher elevation, smaller water. Wild cutthroat and brook trout present in upper reaches alongside rainbow and brown. More remote character.
Rainbow Trout
Dominant species throughout. Wild fish averaging 10–15 inches. Respond well to Caddis and attractor dry fly patterns in summer.
Brown Trout
Present in lower and mid-canyon sections. Larger average size than rainbows. Best during fall BWO hatches and streamer fishing.
Cutthroat Trout
Present in upper canyon reaches. Colorado River Cutthroat — the native subspecies. Less common but highly valued for conservation significance.
The Poudre Canyon's mid-week access is dramatically better than weekends — Fort Collins proximity means significant weekend pressure on the lower canyon.
Post-runoff fishing in mid-June is exceptional — fish are hungry after weeks of high water and the canyon is at its most lush and beautiful.
The upper canyon above Poudre Park holds Colorado River Cutthroat — one of Colorado's rarest native fish subspecies. Handle with extreme care and release immediately.
The canyon section between Mishawaka and Rustic has the best balance of quality water and solitude — plan your access points before driving up.
