Yampa River Fly Fishing Report – Steamboat Springs (Aug 29, 2025)

Listen to the Podcast

The Yampa is classic late-summer: cool and fishy in the mornings, too hot by mid-day. Colorado Parks & Wildlife has a voluntary closure from 2 PM–midnight on stretches through Steamboat Springs due to water temps climbing above 71°F. That means early mornings are your window.

Flows are holding around 1,250 CFS, clarity is improving quickly after monsoon bumps, and trout are keyed in on Trico spinners, PMDs, and terrestrials. Fires in Routt County have triggered Stage 2 fire restrictions, so no campfires or charcoal at riverside camps.

Fire & Closure Update – Lee Fire

The Lee Fire, burning southeast of Craig, has grown past 3,000 acres and continues to impact conditions in the Yampa Valley. While the fire itself isn’t directly affecting river access in Steamboat Springs, smoke and air quality can fluctuate daily depending on wind direction.

More importantly, Colorado Parks & Wildlife has implemented a voluntary fishing closure from 2 PM to midnight on the Yampa through Steamboat Springs due to rising afternoon water temperatures. Combined with ongoing fire danger in Routt County (Stage 2 Fire Restrictions), anglers are strongly encouraged to fish only in the mornings and to avoid stressing fish during heat spikes.

Q: Are fires affecting fishing?
A: Not directly on the river, but Routt County has Stage 2 restrictions — no campfires or charcoal.

Q: What’s the best hatch right now?
A: Trico spinner falls at sunrise are the most consistent. PMDs follow mid-morning.

Q: Is the Yampa wadeable at current flows?
A: In sections, yes. At ~1,250 CFS, wading is possible in riffles and tailouts but stay cautious.
