Williams Fork River Report

Fishing Report

UPDATED: 6/14/2022

Flow: 528 cfsRiver Graph

The Williams Fork River is best known for its tailwater section, which is released from the Williams Fork Reservoir, and flows into the Colorado River a few miles downstream of its origin. The Williams Fork tailwater fishes best when it has enough CFS to entice fish from the Colorado River to run up it ( lets say between 100-200 CFS). A very solid population of midges, Baetis, PMD’s, and caddis exist in the Williams Fork below the dam. Also notable are mosquito’s that develop in this area, they are second only to the mighty mosquitos of Muddy Creek. Bring DEET, cover all skin, and wear bug nets during peek mosquito season. A light nymph rig is the norm for fishing this stretch of water, although strong hatches can produce solid dry fly fishing at times. Streamer fishing can also be good here in the fall.

Guide Tip of the Week:

Flows have shot up to 600 cfs. This is a high flow to fish this tailwater but can be productive using bigger nymphs and streamers. Use large stonefly or worm patterns with a hefty amount of weight to cut down through the fast flows. Use heavy streamer patterns like Sculpzillas and Gongas.

Bugs, fish, and water temps:
Guides Jack Specht and Davis Murane recently got out with owner Ben McCormick for a day on the Williams Fork Tailwater. There are lots of Brown trout still spawning in the system (as of 12/7) but we found plenty of healthy rainbow trout in the heads of runs. 


Small pheasant tails, midges and eggs were the main ticket for the day!

42 Degrees at 2 PM.

A healthy rainbow that ate a Poison Tung.

Yum, Midges!
