Lebanon Dam, located in Linn County, Oregon, is a concrete structure completed in 1925 and owned by the local government.
With a primary purpose of water supply, this dam also serves for hydroelectric power generation, irrigation, and water supply. Standing at a height of 7.5 feet and spanning 450 feet in length, Lebanon Dam holds a storage capacity of 149 acre-feet and covers a surface area of 27 acres, drawing water from the South Santiam River.
Managed by the Federal Energy Regulatory Commission, Lebanon Dam's controlled spillway with a width of 320 feet helps regulate water flow and prevent flooding in the area. Although classified as having a low hazard potential, the dam's risk assessment is marked as very high, denoting the importance of regular inspections and monitoring. Despite lacking a current condition assessment, the dam's emergency action plan was last revised in December 2021, ensuring preparedness for any unforeseen events.
For water resource and climate enthusiasts, Lebanon Dam stands as a vital infrastructure supporting various water-related activities in the region. Its historical significance and role in water management make it a noteworthy site for further study and appreciation of the complex interplay between human development and natural resources in the context of sustainable water use and climate resilience.
