Scoggins is a fascinating water resource in Forest Grove, Oregon, managed by the Bureau of Reclamation for irrigation purposes. The dam, completed in 1974, stands at an impressive 151 feet in height and holds a storage capacity of 62,540 acre-feet. This earth dam, located on Scoggins Creek, is crucial for providing water supply to the region and covers a surface area of 1,157 acres.

With a high hazard potential and very high risk assessment, Scoggins Dam has undergone modifications in 2004 to enhance its mechanical and seismic resilience. The controlled spillway, with a width of 38 feet, plays a crucial role in managing water discharge during high-flow events. Despite its critical importance, the condition assessment of the dam is currently not available, highlighting the need for ongoing monitoring and maintenance to ensure its structural integrity and safety.

Managed by the Bureau of Reclamation, Scoggins Dam is a vital infrastructure for water management in the region, serving both irrigation and water supply purposes. With its rich history dating back to the 1970s, this dam continues to play a significant role in supporting agricultural activities and water needs in the area. As a key player in the water resource management landscape, Scoggins Dam's resilience and operational efficiency are essential for safeguarding the surrounding communities and ecosystems against potential hazards and risks.
