Colorado River:       

Upper Section

Weekly Overview:

February 24, 2020:

  • Technicality: 2/5

  • You’re in for another moderately productive week on the Upper Colorado. Most of the water is covered in ice, but you can still manage to fish at or below the confluence of the Williams Fork. Trout here are not terribly selective when it comes to your flies, but have been fairly sluggish with low flow and sub-freezing air temps. The heavy nymph rig with flashy lead flies will produce the best results this week. Lead with a red Copper John, Rainbow Warrior or Flashback Pheasant Tail followed by one or more smaller midge or egg patterns. When it comes to midges, we’ve found darker colors to be the most productive. This week will be cold, yet again, so give the water time to warm up before hitting the water. 10 am to 3 pm has been the most productive window to fish. In the early hours, look to fish the outer seams and large drop offs and as the day goes on, shift your attention to the deep pools and slow runs.

Detailed River Info:

Background:


The Colorado River, which flows through seven US states and two Mexican states originates in Colorado's Rocky Mountain National Park. There are three sections of river as it pertains to the state of Colorado, the Upper, Middle and Lower. The Upper Colorado is a comparatively large freestone river that originates at the confluence of the Frasier River west of Granby and stretches to the confluence with Troublesome Creek west of Parshall. This picturesque stretch of river, which is lined with cottonwoods and willows, earned its Gold Medal status for its plethora of medium to large sized brown and rainbow trout. 

Angling:
Fishing on this smooth and meandering section of the Colorado is great for anglers of all skill sets and can be fished most of the year. Feature wise, this section provides everything from shallow riffles and slow runs to deep pools. Nymphing and streamer fishing are both effective, but it is most known for its summer dry fly fishing. During this time, there is an abundance of PMD, Caddis and Stoneflies. However, the Salmon fly hatch is arguably what entices anglers the most.

There are a number of great public access points. The following access points reference Granby as the starting point.
