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 provides strong Brown Trout support for the lower Williams Fork. Brown and Rainbow Trout are both described in the tailwater by the regional fishing guide; neither account establishes current species-specific catch odds (Blue Quill Angler; Colorado Fishing Network).
- Keep three waters distinct: the reservoir, the upper river and the tailwater. FishColorado’s Brown/Rainbow/Brook small-creek description concerns the upper river near Ute Pass, not a verified Brook Trout population below the dam (FishColorado reach descriptions).
- 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).

Species and special rules are Colorado Parks and Wildlife's. Statewide rules apply everywhere. Before you fish, check land ownership, CPW's current regulations and its temporary closures for drought and low water.
How we pick these
Species are CPW's records from its Fishing Atlas. A creek missing from this list may still hold fish; CPW simply has no record for it. The list runs in the order each one joins the Williams Fork River, from the headwaters down, and "joins" names the nearest town to where it does on the same side of the mountains: a Census place, or a town with its own post office. Flow is how USGS maps each channel, not a live reading.
Special rules are the ones CPW writes for each creek in its Fishing Atlas. Rules CPW writes for the river itself, such as closures around a creek's mouth, are not repeated on the creek, and no directions lead into water CPW closes all year.
Away from CPW access points, check land ownership before you fish.
Getting to the Williams Fork River
No official land-management agency names a public access point on the Williams Fork tailwater itself (dam to the Colorado River confluence) -- we're publishing only the confirmed regulation below rather than a guessed access list.
- 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.
