The Upper Arkansas River, running from Leadville to Buena Vista, is an angler’s dream, especially during the fall months when the air is crisp, the water is clear, and the fish are hungry. This high-altitude section features a mix of slow meandering waters and fast, rocky runs, making it a versatile playground for fly fishers. Flows are typically between 87-207 CFS, offering ideal conditions for both wading and casting. The cooler temperatures ensure the trout are active, especially during late mornings and early afternoons.
As you move through Hayden Meadows and down to Granite, expect strong hatches of fall baetis, caddis, and the tail end of the golden stonefly hatch. These hatches bring the trout to the surface, making this section a hotspot for dry fly and dry-dropper rigs. For those who prefer nymphing, the rocky pocket water near Buena Vista provides great opportunities, especially when combined with terrestrials like grasshoppers, ants, and beetles still hanging around from summer.
The trout here are structure-oriented, hiding behind rocks, in seams, or hugging the banks, so accurate casting and stealth are key. And with the incredible views of the Collegiate Peaks in the background, even when the fishing slows, the scenery alone makes it worth the trip.
The Upper Arkansas River is a dream this October! With flows between 87-207 CFS, the river is a blend of clear riffles, deep pools, and boulder-strewn pocket water perfect for brown trout hunting. With the fall colors in full effect along the banks and temperatures cooling off, this high-elevation stretch from Leadville to Buena Vista is prime for a full day of angling adventure. Expect active browns feeding heavily on fall hatches, making for an unforgettable day on the water.

Seasonal Tip
Seasonal Tip
Fall fishing on the Upper Arkansas brings trout out in numbers. Focus on the pocket water near structures or seams, and aim for riffles during mid-morning and early afternoon for the best activity.
Dry Fly
The Blue Wing Olive (BWO) hatch is going strong on cloudy days. Use a Parachute Adams or small BWO pattern (#18-20) in riffles and seams for consistent dry fly action.
Nymphing
Nymphing is productive with a two-fly rig, pairing a Pat’s Rubber Legs as the lead fly and a Pheasant Tail as the trailer. Fish near rocks and deeper runs where trout congregate.
Streamer Fishing
With browns in pre-spawn mode, larger streamers like Mini Sculpins or small leeches are effective. Cast near structure and use slow strips to trigger aggressive takes.
