Completed in 1930, this arch dam stands at a structural height of 275 feet, with a hydraulic height of 215 feet, harnessing the power of the North Fork Skokomish River to generate electricity and provide recreational opportunities. With a storage capacity of 8,800 acre-feet and a maximum discharge of 41,050 cubic feet per second, this dam plays a crucial role in water resource management in the region.
Owned by a public utility, Cushman No 2 is regulated by the Federal Energy Regulatory Commission, with a high hazard potential due to its location and design. Despite its age, the dam remains in good condition with regular inspections and emergency preparedness measures in place. The surrounding area, including the Skokomish Indian Reservation, benefits from the dam's presence, contributing to both energy production and water recreation activities. As a key component of the region's water infrastructure, Cushman No 2 stands as a testament to the intersection of water resource management and climate resilience in the Pacific Northwest.
