What's swimming in the Williams Fork River
- This entry covers the tailwater reach below Williams Fork Reservoir, the stretch this page tracks for live flow.
- Blue Quill Angler calls it one of the best Brown Trout populations in the West, with Rainbow Trout also present and larger fish moving up from the Colorado River during spring and fall spawning runs (Blue Quill Angler).
- FishColorado notes trophy-class Rainbow Trout concentrate near the reservoir outlet (FishColorado).
- The tailwater is restricted to artificial flies and lures only, and every fish caught must be returned to the water immediately (Blue Quill Angler).
- The Williams Fork tailwater itself is not Gold Medal water; that designation applies to the adjacent Colorado River segment it flows into, not this tributary (Blue Quill Angler).
Getting to the Williams Fork River

- Williams Fork Dam downstream to the Colorado River confluence (the entire tailwater): artificial flies and lures only, trout returned to the water immediately (CPW special regulations). No minimum size limit or seasonal closure applies.
