The Lewis River Hydroelectric Projects consist of the Merwin Project, Yale Project, Swift No. 1 Project, and Swift No. 2 Projects, including the associated powerhouses, reservoirs, canals, transmission facilities, recreational facilities, fish hatcheries, and wildlife lands within the Projects’ Boundaries. PacifiCorp owns the Merwin, Yale, and Swift No. 1 Projects, while Cowlitz Public Utility District (PUD) owns the Swift No. 2 Project.

​

Per the Lewis River Hydroelectric Settlement Agreement and Federal Energy Regulatory Commission licenses for the above projects, the Utilities are completing various projects to benefit environmental and social resources.

 

The Utilities have initiated the design of additional fish passage facilities specific to aquatic resources. New facilities include Yale downstream passage and upstream passage at Yale and Swift dams. The design process is supported by experts in fish passage engineering from QRS Consulting, Kleinschmidt Associates, and Art Anderson.
