Remote Fly Fishing on the Blue River Below Green Mountain: Wild Trout, PMDs, and Stonefly Rigs (June 2025 Report)

Welcome to a truly wild stretch of Colorado water: the Blue River below Green Mountain Reservoir. In this week’s episode of Rise Beyond, we head deep into rugged canyon country for one of the state’s most rewarding—but underfished—tailwaters.

Flows are holding around 575 CFS and clarity is solid at 3–4 feet, making this an ideal time to chase wild browns and rainbows with stonefly rigs, PMDs, and a healthy dose of grit. The hike-in nature of this fishery means fewer anglers, unpressured water, and fish that fight like freight trains. If you’re ready to trade parking lots for pine canyons and outlet bridges for eddy-hugging slabs of granite, this one’s for you.

We break down the key hatches happening this week, from mid-morning PMD risers to the early arrival of golden stones. You'll get tips on gear (bring the big net), rig setups (two-fly tungsten nymph rigs or articulated streamers), and how to approach access points like Gore Canyon, BLM roads, and the Colorado River confluence.

Other topics include:

• Why flows below Green Mountain fish better in late spring

• What makes this stretch so unique in the Colorado trout world

• Best time windows to avoid heavy sun and sudden wind shifts

• Local regulations and etiquette reminders for remote water

We also tackle FAQ-style insights like:

• Can I wade safely at this flow?

• Is there camping nearby?

• What makes this spot tougher than the tailwater in Silverthorne?

As always, our focus is on conservation-minded angling and personal responsibility in wild places. Rise Beyond exists to help modern anglers find better water, fish smarter, and connect deeper with Colorado’s rivers.
