The Toutle River is a 17.2-mile (27.7 km) tributary of the Cowlitz River in the U.S. state of Washington. It rises in two forks merging near Toutle below Mount St. Helens and joins the Cowlitz near Castle Rock, 20 miles (32 km) upstream of the larger river's confluence with the Columbia River.The river was altered by the 1980 eruption of Mount St. Helens, a nearby volcano, and subsequent flows of ash and other debris. It was further altered by dredging to remove sediment, and by construction of the Toutle River Sediment Retention Structure on the North Fork Toutle River.
