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:

Flows are a fuzz high on the William’s Fork, but still very fishable.  Williams Fork Reservoir is 100 percent full, so look for Denver Water to match incoming flows.  Anglers are catching mostly browns, with the occasionally rainbow. It’s hard to go wrong with a San Juan Worm, trailed by a Buckskin or Mercury Flashback Pheasant Tail right now. A Sparkle Wing RS 2 is another great fly. For dry flies, a Mathew’s Sparkle Dun (PMD) or Elk Hair Caddis is a good choice. Dry and droppers are never a bad idea in the skinny riffles where trout are feeding voraciously on PMD nymphs or caddis larvae.  The mosquitoes are really bad, so plan accordingly…
