The Animas River is flowing beautifully this October, offering anglers the perfect mix of big water, big fish, and breathtaking fall colors. With flows steady around 300-350 cfs, and the water cooling down to the mid-50s, trout are loving the consistent conditions. The brown trout are getting ready for their spawn, so you can expect some aggressive takes, especially on streamers. It’s also prime time for BWOs and midges, which are keeping the trout active all day. Whether you're wading or floating, the river is offering some fantastic action, and the crowds are starting to thin out—so it’s just you, the fish, and those gorgeous mountain views.
The Animas River near Durango is showing off its late-fall charm, with flows around 150-200 CFS, providing ideal conditions for wading and targeting deeper runs. Water clarity is high, so anglers have excellent visibility for spotting trout, but stealth is a must. As temperatures cool, midday hatches of midges and Blue Wing Olives keep the trout active, with browns and rainbows feeding consistently in slower pools and along deeper seams. This stretch of the Animas offers a mix of wild and stocked trout, adding a unique dynamic to the fishing experience.
For anglers who love a challenge, the Animas delivers in November. Nymphing is the most productive technique, but a well-timed Blue Wing Olive dry fly can yield success during the warmer midday hours. Streamer fishing can also be rewarding, especially in the early morning or late afternoon when larger trout are more likely to chase.

Seasonal Tip
Focus on warmer parts of the day for increased trout activity, particularly around midday. Approach clear water with caution, as fish are more likely to spook easily.
Dry Fly
Midday Blue Wing Olive hatches provide good opportunities for dry fly enthusiasts. Cast near the edges of slow-moving pools where trout rise cautiously.
Nymphing
Nymphing with a Black Beauty or Zebra Midge can yield good results, particularly in riffles and deeper pools. Use light tippet to present your flies naturally in the clearer water.
Streamer Fishing
Early morning and late afternoon are best for streamer fishing. A slow retrieve with an Olive Sculpzilla or small Woolly Bugger works well in deeper sections and near structure.
The Animas River near Durango has designated public access points but also runs through some private land.
