About Dolores River
The Dolores River in southwestern Colorado offers a remote and picturesque fly fishing experience amidst the San Juan Mountains. This river is renowned for its abundant populations of wild brown, cutthroat, rainbow, and cutbow trout, which are often less wary of offerings than those closer to populated areas. Anglers can expect excellent dry fly and nymphing opportunities, particularly in the Upper Dolores and its tributaries, though reaching these pristine waters often requires a 4-wheel drive vehicle and some hiking. Key hatches include midges, Blue Wing Olives, Stoneflies, Caddis, Pale Morning Duns, and Californicus stoneflies, making it a prime destination for prospecting. The stretch below McPhee Reservoir is known for larger fish and higher numbers, while the more secluded upper reaches promise solitude and the chance for trophy catches.
