Upper Blue River Fly Fishing Report

Latest update: 6/30/2018 -- The Blue River above Lake Dillon has some quality fly fishing. Flows have bumped up a little bit to 41 cfs. which is keeping the residents happy. Use stealth and accurate casts to feed these selective trout. Midge clusters, Sprout Midges, and Low Water Beatis #16-22. Tie on a #12-14 Renegade or Foam Caddis trailed with a black Zebra Midge for a productive dry dropper rig. Search for fish on the banks and any shelf or drop off. Slender body #6-10 streamers like a Krystal Bugger work surprisingly well in these parts.

River Information

The Upper Blue River near Breckenridge, much like the Blue below Dillon Reservoir, offers anglers the chance to catch it trout year round. The river will fish much like the lower river and is a good place for beginners to learn. Bug life abounds here and sight fishing opportunities exist throughout. This can be a great option for those looking to avoid the outlet mall crowds, although given it’s proximity to Silverthorne and Breckenridge, still sees a good amount of angling pressure. Light tippets and proper presentations will put fish in the net. 

Recommended Flies

Winter/Spring: Midges, Baetis

Summer: Mayflies, Stoneflies, Midges Caddis, Terrestrials

Fall: Mayflies, Caddis, Midges

Seasonal Conditions

 This stretch is accessible for fishing year round and sees a wide variety of bug life. Anglers will find slightly warmer water temperatures here in the summertime which can produce fantastic hatches of caddis, mayflies and even some stoneflies. Nymphing will still be the go-to method for the majority of the year however. During the Spring and Fall, the river sees some very large fish move out of Dillon  reservoir to spawn. 

River Access

Just north of Breckenridge near the town’s rec center is an area known as the “Stair Steps”.  This area experienced stream improvements many years ago and has created some nice deep holding pools for fish to reside. A bike path follows the majority of the river here allowing easy walking and wading opportunities. Over 3 miles of public water exist here. The Gold Hill Access is another option for anglers in the area. This area offers considerably less water to fish, however due to its proximity to the lake, will have a better chance at holding a big lake fish that has moved into the river.
