Williams Fork River | Colorado

Williams Fork River Fly Fishing Information

The Williams Fork River one of the most beautiful trout streams in the Colorado River Valley.  The Williams Fork River flows out Williams Fork Reservoir and flows roughly 2 miles downstream to meet the mighty Colorado River.  The Williams Fork is a small to medium sized stream.  Much smaller than the Colorado, the Williams Fork can be casted across with a fly rod in any spot.  Cottonwoods, Mule Deer and Elk line the banks of the Williams Fork River, making it the ideal Colorado Fly Fishing experience.

The Williams Fork River can be accessed from HWY 40 at Parshall, Colorado.  At this access area, you must cross the Colorado River at Parshall and then proceed to walk to the confluence of the Williams Fork and Colorado River.  The walk into the Williams Fork usually takes about 20 minutes on a normal day.  The Williams Fork River is a small river and is best fished when flows are between 100-300 CFS.  The Williams Fork River is extremely susceptible to drought and should not be fished when flows are 40 CFS or less.  Healthy populations of brown and rainbow trout call the Williams Fork River home.  Browns naturally make up the majority of the population and the rainbow trout can often be very sizable!

The Williams Fork Reservoir is a tailwater fishery.  Water is released from the bottom of the dam, meaning the Williams Fork River can be fished year around.  The Williams Fork is an extremely high gradient river, meaning the water runs fast and strong!  A wading staff will aid in navigating the current and slippery rocks, especially when flows are above 250 CFS.  Summer and Fall are prime time for the Williams Fork.  Amazing hatches and prime flows mean that the trout fishing can be epic!  This is also irrigation season in the valley, which meant he mosquitoes come out to play!  Bug spray is a must during the summer months, do not leave home with out it.  Access into the Williams Fork can be difficult in the winter.  Snowshoes are needed after a large snow storm and the fishing is often worth it!  Spring time is the runoff period for the Colorado drainage, and that includes the Williams Fork.  Flows can reach an excess of 1000 CFS and fly fishing is not feasible at this point.
