Abstract: This analysis addresses only the permanent solution to potential flooding on the Cowlitz River and disruption of navigation on the Columbia River caused by sediment buildup. A Decision Document (February 1984) dealt with the potential flooding due to a failure of the debris embankment at Spirit Lake. The solution to the Spirit Lake problem, a tunnel to North Fork Toutle River, currently is under construction. The present report also identifies the National Economic Development (NED) plan and its methodology, describes the preferred plan, includes an environmental impact statement, provides a possible cost-sharing formula, and recommends procedures for implementing the long-term solution to the sediment problem.
