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 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:


River Flow: 

Flows are fluctuating daily from 18 cfs to over 200 cfs to provide cold water to the Colorado river. Not an ideal flow fluctuation for this tailwater and we recommend looking elsewhere. 

Water Temperature: 


Water Clarity:

Crystal Clear, barring heavy precipitation, or drastic increase in flow.

Current Food Sources:

stonefly nymphs | caddis larva | Baetis nymphs | midge larva/emergers/adults | eggs | small fish, leeches, etc. |

guide tip of the week:


Very low flows on the Williams Fork will make for tough fishing especially with the giant fluctuations in flows we are seeing daily. Right now we recommend you look elsewhere. If you do choose to fish this tailwater, it will be benificial to search out areas of the river that have 3' or more of depth, and a current that is not too swift.  These deeper areas provide good cover for trout to hold in safely while feeding, and also do not require the trout to expend energy due to the slower current.  Fish any water meeting these criteria thoroughly as trout often "pod up" in these favorable zones.  A nymph rig is normally the best bet here, and small Baetis nymphs, caddis larva, and midges will be the go to bugs here.  Also keep in mind that Larger bugs like golden stonefly nymphs can also do the trick here, and work well as a weight for your rig!
