The Toutle River Sediment Retention Structure was built by the U.S. Army Corps of Engineers on the river in 1989 to prevent this sediment from traveling downstream and clogging the shipping channel of the Columbia River.
It was further altered by dredging to remove sediment and by construction of the Sediment Retention Structure on the river's north fork.

The United States Army Corps of Engineers dredged sediment from the river and built the $65 million Sediment Retention Structure on the North Fork Toutle River to prevent debris from continuing downstream.
