Upper Colorado River Fly Fishing Report

Last Update 02/01/2017 - Winter still holding steady in Middle park, look for available fishing spots to be a toss up until you get below the Williams Fork confluence. Midges are just about all that's going on with these colder water temps, so look for fish to hold in deeper runs and pools/eddies until midge’s begin to pupate and fish start to move into the slower/mid-speed runs to feed. A great starting rig here will consist of an stonefly or worm dropped with a #20 zebra midge, mercury blood midge, brassie or bling midge. 4X and 5X tippet will get you through the day here just be sure to adjust your weight and length until you are occasionally tapping the river bottom. Some warmer days may produce a good midge hatch with plenty of fish eating on top so bring a few midge dries with you, such as a Griffiths gnat or Morgans midge in size #18 - #24. - Mike Price, Professional Fly Fishing Guide Trouts Frisco

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.
