Agency Valley in Oregon, managed by the Bureau of Reclamation, is a vital water resource infrastructure along the North Fork Malheur River. This Federal-owned dam, completed in 1934, stands at a height of 110 feet and serves primarily for flood risk reduction and irrigation purposes. With a storage capacity of 66,000 acre-feet and a surface area of 1912 acres, the dam plays a crucial role in managing water resources in the region.
The dam's controlled spillway, with a width of 60 feet, helps regulate the maximum discharge of 12,100 cubic feet per second, ensuring the safety of downstream areas. Despite its high hazard potential, the dam has not undergone a recent condition assessment. However, emergency action plans have been prepared, and the risk assessment indicates a very high risk level. With a history of serving the local community for decades, Agency Valley remains a key infrastructure for water management and flood control in the area.
Located in Malheur County, Oregon, the Agency Valley dam is a prominent feature in the landscape, providing essential flood protection and irrigation water for the region. Managed by the Bureau of Reclamation, this earth dam stands as a testament to the importance of sustainable water resource management in the face of climate change challenges. As water resource and climate enthusiasts, it is crucial to acknowledge and appreciate the role of such infrastructure in ensuring the resilience and sustainability of our water systems.
