Upper Colorado River Fly Fishing Report

Last Update: 3/15/15- The Colorado is fishing very well for the most part. We've been getting quite a few quality reports lately from customers and I know I'm personally going to be making a trip here as soon as time allows. Stoneflies, eggs, worms and flashy attractor nymphs should all catch fish. From the sounds of it, the Brown Trout are glad winter is over and have begun to feed quite aggressively when conditions are right.

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.


Winter/Spring: Baetis, Midges

Summer: Caddis, Stoneflies, Mayflies, Terrestrials, Streamers

Fall: Caddis, Mayflies, Terrestrials, Streamers

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.
