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 gone down to 54 cfs. This is a low flow to fish this tailwater but it is an excellent option for late winter. A nymph rig is normally the best bet here, and small midges, mayfly nymphs, and caddis larva, are usually the go to bugs. Size down your tippets and flies. On cloudy and overcast days Baetis can go crazy especially once temperatures cool off a bit. It has been much colder in Parshall compared to Silverthorne as of late so keep that in mind. We have been finding more fish lower down rather than higher up in the system.

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!
