Upper Colorado River Fly Fishing Report

Last Update 05/25/2017 - The upper Colorado run-off conditionals are very dependent on the weather right now. Currently, clarity is fair-good but as soon as we see some warmer days be on the look out. Salmonflies have been in full swing, fish are getting full so get it while you can! Fish a Pat’s or other large stone pattern and trail with a medium size (#12-#14) caddis or general attractor nymph like a pearl Crystal PT, red or chartreuse Copper John or etc. Streamers are also a great choice this time of year and if you happen to be fishing when the color is off, this is a good bet to produce some fish..

River Information

Our great state's namesake river rarely disappoints and offers anglers the chance to catch large Rainbow and Brown trout. The upper section- between Windy Gap Reservoir and Kremmling- sees abundant bug life and has earned a Gold Metal rating due to it's thriving fish population. This freestone river offers ample public access and year round fishing.

Seasonal Conditions

While the Colorado is fishable year round, the summer time, and it's abundant insect hatches are definitely what attracts many anglers to this river. Come late June, PMDs and Caddis certainly do their part in getting the trout interested, but it is the Stoneflies- particularly Salmonflies- that really get both the fish and fisherman excited. It's tough to beat spending a summer day throwing a 3" long dry fly to rising fish. Nymphs and Streamers will consistently put fish in the net here as well throughout the year. 


River Access

This section of River stretches from Windy Gap Reservoir (west of Granby) west to the confluence with Troublesome Creek (east of Kremmling).  This section is Gold Metal water and US Hwy 40 follows the Colorado for this section. You can also fish the headwaters of the Colorado River in Rocky Mountain National Park above Granby.
