Colorado River near Parshall | Overview
Just below the confluence of the Colorado River and the Williams Fork River, the Parshall section offers some of the finest year-round trout fishing in Grand County. This productive stretch flows through wide meadows and cottonwood-lined banks, providing a mix of riffles, deep runs, and long, gentle glides that make for classic western fly-fishing. The steady flows from the Williams Fork tailwater help keep this water cool and fishable even through the heat of summer and into the heart of winter. Public access is excellent thanks to the Kemp–Breeze State Wildlife Area and Sunset access points, both managed by Colorado Parks & Wildlife. The Kemp–Breeze unit features several miles of restored stream habitat, with improved structure and deeper holding water for trout. Just upstream, the Sunset access offers easy wading and a quieter experience for anglers looking to explore away from the crowds. Together, these access points provide some of the best public fishing on the upper Colorado.
Current Conditions
Cold weather has the Colorado at Parshall firmly in its winter rhythm. Nymphing with smaller patterns is the most reliable approach, and trout have shifted into softer holding water now that the brown trout spawn has wrapped up. Focus on deeper riffles, slow pockets, and longer tail-outs where fish can conserve energy. Stonefly nymphs, midges, and baetis patterns are all producing, and going smaller—sizes 20–22—can make a big difference. If you’re not finding fish, adjust your depth and keep working the slower winter seams.
