RIVER OF THE MONTH
Cowlitz River A mighty arm of the lower Columbia River, the Cowlitz proper begins on the glaciers of Mount Rainier and then gathers wild tributaries from both Mount Adams and Mount St. Helens before it enters the fertile “Big Bottom Valley” near Randle, Washington. Then it flows past three massive dams, turns south to receive the Toutle River—which bore the brunt of Mount St. Helens’ ash flows—and completes its 105-mile journey to the Columbia at Longview.
Why It Matters

With headwaters on the three Cascade volcanoes, the Cowlitz drains a huge area of southwest Washington. Though heavily dammed, it remains critically important to recovering imperiled native fish runs in the lower Columbia system. It’s also one of the most popular sportfishing rivers in Washington and, upstream, offers ample public access to wilderness areas, hiking, hunting, and some of the best wildlife viewing in the state.
Fish
Once a powerhouse of wild fish production, the Cowlitz still supports native runs of fall and spring Chinook salmon, coho, summer and winter steelhead (above) and cutthroat trout, which all compete with large hatchery runs. If fish passage at the dams improves, it would be a significant step toward rebuilding wild runs to spawn on the river’s healthy upper reaches.
Wildlife
Known for its elk, the Cowlitz Valley, with its wetlands, forests and bottomlands, also supports diverse wildlife like black-tailed deer, river otter, beaver, state-sensitive pileated woodpecker (above) and many raptors and waterfowl. At higher elevations, you’ll find black bear, mountain lion, mountain goat, pika and marmot.
