The Dolores River, winding through the remote and scenic canyons of southwestern Colorado, offers some of the best tailwater fishing in the state. Below McPhee Reservoir, the cold water release creates excellent year-round fishing conditions for brown and rainbow trout. With fall in full swing, the cooler water temperatures and lower flows have brought trout into feeding mode, making October one of the prime times to fish this beautiful river. The river’s solitude and rugged landscape offer an immersive fishing experience, where you’re more likely to see a few big browns than other anglers.
The Dolores River in November offers a serene and scenic fishing experience. With flows at a steady 40-100 CFS, anglers can enjoy excellent wading conditions and crystal-clear water, perfect for sight fishing. Trout are still active, particularly in deeper pools and undercut banks, as they prepare for the colder months. Midges and Blue Wing Olives remain the primary hatches, providing subtle but consistent action throughout the day. The Dolores is known for its wild browns and rainbows, making it a rewarding choice for those who favor technical nymphing.
While this river can be challenging due to its low, clear water, a stealthy approach and small patterns pay off. For the best success, plan to fish midday when the water is at its warmest and the trout are feeding most actively.

Seasonal Tip
In November, aim for warmer midday hours, and use a subtle approach to avoid spooking fish in the low, clear water.
Dry Fly
Look for BWOs in the late morning. Trout will rise for small dries in calmer waters, especially in slower pockets.
Nymphing
A double-nymph rig with a Zebra Midge and small Baetis pattern is very effective in riffles and tailouts. Fish deeper pools with light tippet for best results.
Streamer Fishing
Use an Olive Sculpin or small Woolly Bugger, targeting deep pools and undercut banks. Keep retrieves slow and steady for a chance at larger browns.
The Dolores River includes stretches with designated public access, but certain sections may be adjacent to private property. Respect property boundaries, and always fish at designated access points. Barbless hooks are recommended to protect the trout population, and a Colorado fishing license is required. This is a treasured river, so practicing Leave No Trace principles is essential to preserve its pristine condition.
