Blue River Below Green Mountain Fly Fishing Report – August 6, 2025Cold Water, Hot Window

The Blue below Green Mountain is a tailwater that rewards persistence—and right now, it’s in prime summer form. Flows are around 400 CFS, keeping water temps in the sweet spot and trout feeding steadily through late morning and early afternoon.

PMDs are the main event mid-morning, with Tricos making an early showing and caddis filling in the gaps. Terrestrials are starting to pull fish from the edges, especially ants and beetles in the softer seams.

The clarity is excellent, the crowds are moderate, and this stretch is fishing better than most in Colorado right now

Canyon Mode: Stealth or Bust

Cheesman Canyon doesn’t give up fish in August—you earn every eat. Flows are holding around 210 CFS, the water is gin-clear, and the trout are in graduate school mode. This is a long-leader, small-fly, stealth approach fishery right now.

Your best window is early morning through 11 AM, with Tricos in full swing, PMDs still around, and terrestrials heating up. Midday, the Canyon becomes a chess match: subtle emergers, 6X fluoro, and perfect drifts are the only way you’re getting smiles.

Target tailouts, mid-depth riffles, and the undercut slots behind large boulders. If you want a technical challenge with the payoff of sight-hooking a truly wild South Platte rainbow, this is your arena.

Summer Reset Mode – Yampa Back to Business

After a push of high water, the Yampa through Steamboat is sliding into perfect late-summer shape. Flows are ~1,650 CFS and dropping, clarity is improving daily, and trout are shaking off the runoff hangover. Mid-morning through early afternoon is producing the best action, especially on the upper river and tailwater stretches.

Town water has some tuber traffic after 11 AM, but if you hit it early or head upstream, you’ll find plenty of open runs and happy fish. Caddis and PMDs are the stars right now, with terrestrials becoming more i

Wild, Cold, and Full of Opportunity

The Cache la Poudre is in prime late-summer form—steady 185 CFS flows with clear water and cold temps that keep the trout feeding all day. While midday sun will slow surface action, mornings are producing steady takes on PMDs, caddis, and Tricos, with terrestrials playing a bigger role as August rolls on.

The canyon water is your friend right now—pocket water, riffles, and deep seams are stacked with fish. Dry-dropper rigs are the most versatile option, but a tight-line nymph approach will crush in faster runs. If you’re looking for a break from pressured metro rivers, the Poudre is worth the drive.
