Despite being classified as having an undetermined hazard potential, the dam is currently in a condition assessment status of "Not Available." The risk assessment for the dam is moderate, with a DSAC assigned date still pending. The spillway type is uncontrolled with a width of 36 feet, and the outlet gates are also uncontrolled. The dam is owned privately and falls under the jurisdiction of the USDA NRCS, with no state regulatory agency overseeing its operations.
