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.
Nymphs To Try: Shot Glass Baetis olive size 18-20, Darth Baetis olive size 20-22, Ju-Ju Baetis natural or red size 20-22, RS2’s size 18-22, Buckskin Caddis size 16-18, K's Latex Caddis size 18, Zebra Midge black or olive size 18-22, UV Midge black or brown size 20-22, Desert Storm red or chartreuse 20-24, pegged eggs, TDJ Golden Stone size 14-16
Dries To Try: Matthew's Sparkle Dun olive size 18-22, Parachute Adams size 18-22, CDC Morgan's Midge size 18-22, black/grey/cream Brook Sprouts Midge size 20-24,
Streamers To Try: Think small to medium when chucking meat here.... Slump Busters, Wooly Buggers, Meat Whistles, Baby Gonga, and leach patterns.
At 350 CFS the Williams Fork tailwater is a bit higher than our preferred stream flow, but it is still not a bad option for the time being. Higher flows do mean that there is plenty of water for fish from the colorado to move up and hold in. Expect caddis, Blue Wing Olives, yellow Sallies, worms, and midges to be on the menu. A nymph rig will probably buyout best bet for the time being, unless you prefer to strip some small to medium sized streamers, which could also be effective.
The flows on the Williamsfork tailwater have been fluctuating quite a bit recently. Keep an eye out for stable flows between 100 and 200CFS, which we believe are ideal for this stretch of water. Blue Wing Olive Mayflies, Caddis Larva, and Midges have been our go to bugs for the time being. Also keep larger Stonefly patterns in mind if you are fishing the confluence area with the Colorado River.
