Cache la Poudre River at Fort Collins
Seasonal notes
The Cache la Poudre is Colorado's only federally designated Wild and Scenic River, and the segment through Fort Collins and the Poudre Canyon earns that designation on the strength of a genuinely wild brown and rainbow trout fishery sustained by a self-reproducing population rather than hatchery stockings. The canyon section (US-14 above Ted's Place) is classic Rocky Mountain freestone — deeply shaded, swift-running, and full of steeply undercut banks where large browns shelter. Fort Collins itself provides accessible urban water with fish visible in the clear green pools. Summer flows are heavily managed by upstream diversions for agriculture and municipal supply, which means August can push the river to precarious lows — the app's flow data is particularly important here. September through October is the best all-around window: stable flows, active browns staging for fall, and the cottonwoods along the canyon blazing orange.

Special regulations
Wild and Scenic River designation means no new water diversions or impoundments in the corridor, which is good for the fishery. Standard Colorado fishing regulations apply through most of the Poudre; there are no Gold Medal or catch-and-release restrictions on this segment, which surprises many visitors given the quality of the wild population. CPW does not actively stock the canyon as a management choice to preserve the wild population's genetic integrity. Check for any emergency closures during drought years, as CPW has issued low-flow fishing advisories on the Poudre in severe drought seasons.
Quick ref: Colorado's only Wild & Scenic river; wild brown + rainbow; upstream diversions reduce summer flow
