Current River Flow Updates

Latest update: 10/1/19 -- Starting October 1st, and last somewhere in the 4-8 week range, Colorado Parks and Wildlife will be operating a stream restoration project on the Williams Fork River from the dam to the confluence of the Colorado River. It is suggested that you avoid this area until the restoration process is completed. Note- Due to the project, there will be an excessive amount of sediment being kicked up in the Williams Fork. All of this sediment will flow down to the Colorado River, resulting in off color water from the confluence downstream until the sediment has had enough time to settle. We will make sure to post any updates we receive from CPW and inform you when the river is back open for business.

River Information

The Williams Fork river is another tributary of the Colorado worth exploring. The river is divided by Williams Fork Reservoir. The upper section is a classic high mountain stream ideal for a small 1-3wt fly rod and a box of bushy dry flies. The tailwater section below the reservoir is where most people head when fishing the "Willy's Fork". This tailwater can be quite susceptible to annual flows and the fishing can be very tough during low water years. During normal to high water years, the fishing can be superb, offering anglers the chance to catch sizeable, hard fighting Rainbow and Brown trout. This tailwater section is fairly short, coming in at about 2 miles long, before it reaches the Colorado River in the town of Parshall.

Seasonal Conditions

The Williams Fork can be fished 12 months a year, however, Summer and Fall will certainly be the most productive seasons. Come summer, hatches abound and the dry fly fishing can be phenomenal. Mayflies, Caddis, Terrestrials, and small Stoneflies will all catch fish in both their dry and nymph varieties.

River access

The tailwater section of the Williams Fork can be accessed in two locations - both of which require approximately a 20 minute hike so make sure to bring some hydration. The river can be accessed off Hwy 40 at the town of Parshall by crossing the Colorado River and walking to the confluence. The other option is to head down County Rd 3, just east of Parshall, like you're headed to Williams Fork Reservoir. There is a DOW parking area on the west side of the road, approximately 1/3 mile south of the Colorado RIver. From here, follow the foot path to the river which is about 1 mile away.
