On July 10, 2025, the U.S. Army Corps of Engineers, Walla Walla District, celebrated the 3,200-feet-long Lower Granite Lock and Dam’s 50 years of service to the Pacific Northwest along with the generations of people who made it possible.
Lower Granite Lock and Dam, located on the Snake River in southeastern Washington, includes a dam, navigation lock, powerhouse, fish ladder, and associated facilities. The project provides hydropower, navigation, flood risk management, fish and wildlife habitat, recreation, and incidental irrigation. The dam spans approximately 3,200 feet and has an effective height of 100 feet. It is a concrete gravity structure with an earthfill right abutment embankment.
