About the Yakima River
Central Washington — Kittitas & Yakima Counties · Canyon Section — Cle Elum to Ellensburg

The Yakima River between Cle Elum and Yakima is the finest and most celebrated trout fishery in Washington State — a tailwater-influenced river that flows east through a dramatic canyon before opening into the broad Yakima Valley, maintaining consistent cold temperatures and exceptional insect populations that have made it a Pacific Northwest dry fly institution.

The Yakima is the only Class I trout fishery in Washington, a designation reflecting its extraordinary quality and requiring catch-and-release with barbless hooks throughout most of the productive canyon and lower canyon sections. Wild rainbow averaging 14–18 inches dominate the system, with some sections holding exceptional fish over 22 inches. These are educated, selective rainbows that have seen generations of fly fishers — the kind of fish that demand good presentations and appropriate patterns.

The canyon section between Cle Elum and Ellensburg is the Yakima's finest water — a dramatic basalt canyon where the river alternates between powerful riffles and long, flat glides ideal for dry fly fishing. PMD hatches in summer and Blue-Winged Olive hatches in spring and fall provide the best dry fly opportunities, while the October Caddis emergence is the Yakima's signature fall event — massive orange caddis that trigger aggressive surface feeding from the river's largest fish.

The Yakima is Washington State's only significant freestone/tailwater trout river, making it the destination for the entire Seattle-Tacoma metropolitan area (2–2.5 hours). Despite the proximity to 4 million people, the canyon sections maintain reasonable quality due to the Class I designation and consistent angler education about catch-and-release practices.

Access & Sections
Public access points and section descriptions

Cle Elum — Upper Canyon

Cle Elum is the gateway to the upper canyon. River access from Canyon Road paralleling the river downstream. Most productive PMD and summer dry fly water.

Ellensburg — Valley Access

Multiple public access sites in the Ellensburg area. Transition from canyon to valley character. Good September and October fishing for large fish keyed on October Caddis.

Lower Canyon — Umtanum Area

Access via Umtanum Road south of Ellensburg. Remote canyon section with less pressure. Walk-in required for best access. Drift boat popular in this section.

Species & Regulations
What swims here and how you can fish for it

Rainbow Trout

Dominant species throughout. Wild fish averaging 14–18 inches with exceptional fish over 22 inches in prime sections. Highly selective — especially in flat, slow glides. Most active during PMD and October Caddis hatches.

Brown Trout

Present in lower sections. Less numerous than rainbows but larger on average. Most active during fall hatches and streamer fishing in October–November.

Regulations Summary
⚠ Washington fishing license required. The Yakima is a Class I (Wild Trout) fishery — catch and release, barbless hooks required throughout the most productive sections. Check WDFW for current section-specific regulations. Regulations are strictly enforced.
Pro Tips
Local knowledge from guides who fish this water
💡

October Caddis fishing on the Yakima (September–October) is the river's premier event — large, orange caddis trigger the year's most aggressive surface feeding.

💡

Yakima fish are educated — use 5x or 6x tippet and make drag-free presentations. The flat glides require perfect drifts.

💡

Morning mist in the canyon on fall days means BWO hatches that can be spectacular — be on the water at first light in September and October.

💡

The drive from Seattle (2.5 hours) is worth every minute — the Yakima is genuinely world-class water that most Pacific Northwest anglers underutilize.
