Fly Fishing Conditions & Tips from Pat Dorsey for the Williams Fork River

The Williams Fork River is a top-notch fishery of its own. This beautiful fishery is nestled between the Williams Peaks and Middle Park and is truly a fly-fishing paradise. The two-mile stretch between the upper boundary of the Kemp Unit and the confluence of the Colorado River is a mixture or riffles, runs, and pocket water with one of the best populations of brown trout in the “west”. A 30-minute hike to the river keeps the crowds to a minimum. Anglers can catch trout with a variety of methods including nymphs, streamers, and dry flies. The hatches include caddis, blue-winged olives, midges, Tricos, and red quills. Being a tributary of the Colorado River-spring and fall-spawn runs bring some “lunkers” into the stream. Ideal flows for the “Fork” are between 100 and 250 cfs. The regulations are flies and lures only and all fish must be returned to the water immediately.

The Williams Fork is one of the prettiest places on the planet. This Williams Fork is proof that trout don't live in ugly places.

Tips & Other Information:

The Williams Fork is starting to shape and fish nicely. Mosquitoes are still a big problem so plan accordingly. Plan on reliable hatches of caddis, red quills, PMD’s,  Tricos, and  blue-winged olives. It’s hard to go wrong with a San Juan Worm trailed by a size 18 Mercury Flashback Pheasant Tail, #18 Buckskin, or #20 Sparkle Wing RS 2 during the non-hatch periods. Mathew’s Sparkle Duns, Stalcup’s CDC Biot Comparadun, and Elk Hair Caddis have been the best dry flies when a hatch becomes evident.
