Cowlitz Falls Dam
Cowlitz Falls Dam is a 70 megawatt hydroelectric dam in Lewis County, Washington. It was constructed in the early 1990s and completed in 1994. The dam is 140 feet (43 m) high and 700 feet (210 m) wide.
The Cowlitz Falls Project impounds the Cowlitz River and produces on average 260 gigawatthours annually for the local public utility, the Lewis County Public Utility District, or about one-third of its annual electrical needs. The facility was developed jointly with the Bonneville Power Administration, and the BPA bears the direct cost of operating and maintaining the dam.
