Lower Roaring Fork Fishing Report — August 17, 2026

The Lower Roaring Fork has been a pleasant surprise this week — flows running around 600 CFS and up have made for a fun, fishable float, and water temperatures have been staying cold enough to keep trout healthy and active throughout the day.

Higher flows push fish to the edges and softer seams, so focus your drifts along the banks, behind structure, and in the slower water off the main current. Float fishing has been the way to cover water efficiently and find where fish are holding. If you've been waiting for a good window to get on the lower Fork, this is it.

What to Throw on the Lower Roaring Fork Right Now

• Chubby Chernobyl — Size 8–12 — The go-to hopper pattern for float fishing the lower Fork. Fish it tight to the banks with a nymph dropper for a deadly combo in higher flows.
• Pat's Rubber Legs — Size 6–10 — With flows up, a big stonefly nymph like Pat's Rubber Legs is a great search pattern. Dead drift it through deeper runs and pockets where fish are stacking up.
• Jiggy Duracell — Purple — Size 14–18 — A killer attractor nymph that gets down fast in higher flows. Fish it as your lead dropper or on a two-nymph rig through faster runs and deeper seams.
• Jiggy Soft Hackle — Carrot — Size 14–18 — A great trailing fly with a ton of movement in the current. Fish it behind a heavier lead nymph and let it swing at the end of the drift.
• CDC Flashback Pheasant Tail — Size 16–18 — A consistent producer between hatches. Pair it with a heavier lead fly to get it into the strike zone in faster water.
• Zebra Midge — Size 20–24 — When fish get selective, a Zebra Midge as a trailing fly has been saving the day. Always worth having a few on a float.

Water temps staying cold is the big story on the lower Fork right now — it's what's making this float window possible. We'll keep monitoring conditions and update you if anything changes.
