Built in 1964 by the USDA NRCS, this earth dam stands at 37 feet tall and spans 1130 feet in length, holding a maximum storage capacity of 504 acre-feet. The dam is equipped with a controlled spillway and a single valve outlet gate, designed to manage a maximum discharge of 1920 cubic feet per second in case of emergencies.
Despite its low hazard potential, the dam is classified as having a very high risk due to its condition not being rated and lacking updated emergency action plans. The last inspection was conducted in 1980, with an inspection frequency of 5 years. The dam's risk management measures and readiness for potential inundation events are currently not specified, indicating a need for further assessment and preparation to ensure the safety and integrity of the structure and surrounding areas in the face of climate-related challenges.
