The Toutle River is a 17-mile-long tributary of the Cowlitz River located in Washington state. Historically, it was known for its abundant fish populations and was a vital resource for Indigenous peoples. However, in 1980, the eruption of Mount St. Helens caused a massive mudflow that destroyed the river's ecosystem. There are two reservoirs on the river, the Swift Reservoir and the Yale Reservoir. The Swift Reservoir was created in 1958 by the Swift Dam, which is used for hydroelectric power generation. The Yale Reservoir was created in 1953 by the Yale Dam, which is also used for hydroelectric power generation. The Toutle River is used for recreational activities such as fishing, kayaking, and hiking. It also supports agriculture in the surrounding area.
