Despite its low hazard potential, the dam is classified as having a very high risk due to its location and potential consequences in case of failure.
Managed by the Oklahoma Water Resources Board, this dam features a controlled spillway and a single valve outlet gate for water release. While it has not been rated for condition assessment, the dam undergoes inspections every 5 years, with the last one dating back to 1980. Surrounded by a surface area of 15 acres, this structure plays a crucial role in mitigating flood risks for the local community in Harris, Oklahoma. With a comprehensive risk assessment in place, efforts are being made to ensure the safety and integrity of this vital water resource infrastructure.
