Oneida Embankment, located in Idaho along the Bear River, is a significant earth dam constructed in 1921 for the primary purpose of irrigation. With a structural height of 60 feet and a hydraulic height of 40 feet, this dam plays a crucial role in water resource management in the region. It boasts a storage capacity of 19,000 acre-feet and covers a surface area of 357 acres, serving the agricultural needs of the area.

Managed by a private owner, the Oneida Embankment is regulated by the Idaho Department of Water Resources and inspected by the Federal Energy Regulatory Commission. With a high hazard potential and risk assessment rating of 'High (2)', this dam requires diligent monitoring and maintenance to ensure its integrity and safety. Despite its age, the dam has not undergone any major modifications and its condition assessment remains unavailable, highlighting the need for ongoing assessment and risk management measures.

In addition to irrigation, the dam also serves hydroelectric and recreational purposes, making it a multi-functional structure vital for the community. The Oneida Embankment stands as a testament to the engineering and foresight of its designers, contributing to the sustainable use of water resources in the region while also providing opportunities for recreation and energy generation.
