Stream Report, Effective Patterns, & Expert Information for Fly Fishing the Colorado River

The Colorado River begins its journey in Rocky Mountain National Park and heads west offering anglers several opportunities to sample this great stream. Near the small community of Granby is the confluence of the Fraser River. At this point the river is a meandering, meadow stream flowing through lush ranchland and the river remains this way until it hit Byers Canyon. Byers Canyon is only about 3/4 mile long and this section is tough to negotiate, especially during higher flows. Below Byers Canyon the river is “as good as it gets” with many access points including Paul Gilbert, Lone Buck, Kemp-Breeze, Sun Set Ranch, Powers Unit, Reeder Creek and the Pump House to Radium stretch. The Colorado is lined with cottonwood trees and willows and is a dry fly paradise. Anglers can expect to catch a mixed bag of both browns and rainbows. The regulations in this area are flies and lures only and all fish must be returned to the water immediately.

Fishing the Colorado River should be on everyone's bucket list. Whether you're a walk/wade fisherman or prefer float-fishing, this river has something for everyone!

Tips & Other Information:

The Colorado River is starting to shape up and become manageable again. Look for the flows to continue to drop and for fishing to get better by the day. Anglers should prepare themselves for hatches of PMD’s, Yellow Sallies, Caddis, Red Quills, and Tricos. Make sure you bring plenty of Deep Woods Off!
