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:


River Flow: 

Flows are currently around 270 cfs. If this flow holds somewhat steady then fishing could get good here.


Water Temperature: 

Low 40s through low 50's


Water Clarity:

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


Current Food Sources:

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

guide tip of the week:


Flows have been bumped to 270 cfs. These higher flows should do great things for fishing. Dont be afraid to try some bigger bugs with the higher flows as well (think Craneflies and leeches). A hopper dropper rig is normally the best bet here, and small midges, mayfly nymphs, and caddis larva, are usually the go to bugs to put under a hopper here. Tricos have been making their way up the river as well from the confluence with the Colorado. On cloudy and overcast days Baetis can go crazy especially once temperatures cool off a bit. BRING DEET and watch out for moose.
