Lower Granite Lock And Dam - West Levee


May 2, 2024

Lower Granite Lock and Dam - West Levee, also known as the Lewiston Levees, is a federal structure located in Asotin, Washington, along the Snake River. Completed in 1974 by the US Army Corps of Engineers, the primary purpose of this earth dam is hydroelectric power generation, flood risk reduction, and navigation support. While specific structural details such as height and length are not provided, the dam is associated with two other structures and is maintained by the US Army Corps of Engineers.

With a high hazard potential, the Lower Granite Lock and Dam - West Levee is subject to regular inspections and risk management measures to mitigate potential flooding risks. The US Army Corps of Engineers actively monitors the dam's condition, collaborates with emergency managers, and updates emergency action plans to ensure preparedness in case of a dam-related emergency. The dam's operation involves managing water levels and releasing water as needed to maintain structural integrity, especially during severe weather events that could impact water levels in the system. More detailed information about the dam's risk assessment and management strategies will be provided in the future.
