This private dam stands at a height of 22 feet and has a storage capacity of 70 acre-feet, serving various other purposes besides flood control. The dam is primarily made of earth and stone materials, with a spillway width of 75 feet and a surface area of 9.2 acres.
Managed by the North Dakota State Water Commission, Amoco Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. Although its hazard potential is classified as undetermined and its condition assessment is not rated, the risk assessment for the dam is moderate. While no emergency action plan or inundation maps are currently in place, the dam meets state guidelines and is inspected regularly.
For water resource and climate enthusiasts, Amoco Dam presents an intriguing case study in dam management and regulation. Its location along the Missouri River and its history of seismic modification in 1974 add to its significance in the region. With a moderate risk assessment, the dam serves as a focal point for ongoing monitoring and potential risk management measures in the future.
