Colorado River:       

Upper Section

Weekly Overview:

October 1, 2018: 

  • Technicality: 2/5

  • Fall on the Upper Colorado often presents some incredible fishing. Currently, water clarity is pristine making for great sight fishing. Additionally, the browns are in spawning mode and feeding more aggressively. We’re continuing to see some great hatch activity throughout much of the day. Caddis and BWOs have been the variety of choice when fished along the banks and through the slower water. Streamers, as well, have produced some great takes and fun fights. This week will generally be slow from a streamer perspective, but a dark colored Wooly Bugger stripped solely through the water will be tough for fish to turn down. With inclement weather and consistently low air pressure you’re going to want to spend most of your time fishing sub-surface nymphs making sure you’ve applied enough weight to find the appropriate feeding lanes.

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. 

River Access:

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