The Arkansas River is deep into its winter transition, and like the Colorado, each section behaves differently depending on elevation, gradient, canyon structure, and overnight temperatures. From the cold oxygen-rich pocket water above Leadville, to the more forgiving mid-elevation freestone through Buena Vista and Salida, down to the wider, warmer water near Cañon City, the Arkansas is showing its classic split personality this time of year.

The Arkansas River remains one of Colorado’s most reliable winter fisheries due to its variety of structure, elevation changes, and consistent public access. From the Upper Arkansas near Buena Vista to the canyon and tailwater-influenced stretches downstream, the river is holding in a stable winter pattern with predictable trout behavior and manageable flows.

Across all sections, trout are set up in slower winter lanes, feeding selectively during short midday windows. Midges dominate, stonefly nymphs provide weight and profile, and clean drifts matter more than fly changes. Anglers willing to adjust depth and move frequently are finding consistent success.
