About This Water

Southwest Washington steelhead river with summer and winter runs. Excellent fly water throughout.

Fishing Recommendations

The Kalama River is a crown jewel of Southwest Washington fly fishing. Flowing from the western slopes of Mount St. Helens to the Columbia River, it offers some of the most classic "swing water" in the Pacific Northwest. It is a river of basalt ledges, deep emerald pools, and a storied history that has shaped modern steelhead fly fishing.


🎣 Location Overview

The Kalama is a quintessential freestone-style river characterized by its clarity and rugged beauty. Unlike its larger neighbor, the Cowlitz, the Kalama is smaller and more intimate, making it a favorite for fly anglers who prefer wading and Spey casting.

What makes it special is the gradient and structure. The river is littered with basalt shelves and "buckets" where steelhead love to rest. The water stays remarkably clear even when other rivers are blown out, thanks to its forested drainage and volcanic rock base. It feels like a "stepped" river, with distinct pools separated by beautiful riffles and runs.
