Williams Fork River Report

Fishing Report

UPDATED: 6/20/24

Flow: 590 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.

Current Conditions:

Guide Tip of the Week:

We are finally seeing more water on the Willie’s tailwater. With a little more water, the fish are sure to be a little less spooky. Midges and baetis are going to be the go-to bugs for the next couple months. Don’t hesitate to throw an egg or small leech, We have been seeing good hatches of midges during the warmer parts of the day. A two or three fly nymph rig will be the best way to catch fish here. Light tippet and small flies are necessary for the low clear flows.
