Fly Fishing Colorado River - Parshall

Fly fishing Colorado River Parshall section begins just below the Williams Fork confluence and flows gently through broad high‐mesa meadows and extensive cottonwood groves before angling toward Parshall, Colorado. This Gold Medal stretch features cold, clear, freestone water that supports vibrant populations of wild brown trout and rainbow trout, often topped by occasional cutthroat in back eddies. The river here traverses open sagebrush flats backed by distant fourteen‐thousand‐foot peaks of the Never Summer Range, creating a panoramic Western riverscape filled with willow‐lined banks, sage‐choked terraces, and stands of quaking aspen that shimmer in the breeze. Rocky islands and gravel bars emerge at low flows, while deeper runs and gently sloping riffles offer prime feeding lanes for trout.

From late April through early June, rising snowmelt pushes flows into the 150–400 CFS range, drawing prolific blue‐winged olive hatches to shallow riffles near the Parshall boat ramp and Chapel Pond area. Anglers employing tight‐line nymphing with slender zebra midge and pheasant tail patterns consistently hook trout holding in mid‐river seams. By mid‐June, caddis hatches become dominant, lighting up shallow flats under willow overhangs where trout sip emergers and duns. Summer (July–August) brings PMD (Pale Morning Dun) activity in early mornings, followed by hopper and terrestrial fishing as hoppers drop onto sandy bars and grassy benches across open meadows. Late summer afternoons reward dry‐dropper rigs fished beneath cottonwood canopies, while evening mayfly swarms spark surface takes in deeper runs near the Highway 40 bridge. Fall (September–October) sees stable flows under golden aspens, with sporadic midge clouds and late‐season mayfly hatches making tight‐line nymph rigs and micro‐dry flies deadly on calm stretches.

Access is straightforward via Highway 40 frontage roads. Wade anglers can slip in at multiple pullouts near the Parshall boat ramp and the North Fork Road bridge. Rustic parking areas along County Road 11 provide additional roadside entry points to long wade sections. Anglers should be prepared for variable flows; under 200 CFS, target shallow riffles and gravel bars, while flows above 350 CFS require deeper runs and streamer tactics.
