About Our Fly Fishing Report

Pat Dorsey's Stream and Fly Fishing Report provides anglers with up-to-date information on several of Colorado's renowned trout streams. Pat Dorsey's fly fishing report is generated from many of the Blue Quill Angler's veteran guides who frequently visit these rivers on a regular basis. The Blue Quill Angler has guides on the South Platte, Blue, Colorado, William's Fork and North Fork of the South Platte several times a week. This incredible network allows you to share their successful tips, and techniques, as well as keep you informed on effective fly patterns.

Our goal is to keep you apprised on several of Colorado's best trout streams as the conditions change on a weekly basis. We want to stack the odds in your favor--putting you in the right place, at the right time, with the right flies! Contact me - with any questions or concerns about current conditions.
