Incident DescriptionPrimary spillway riser had been removed prior to Hurricane Florence (without a permit/approval from the State) and pond was drained. Heavy precipitation on the watershed over approximately 72 hours completely filled the impoundment and caused overtopping of the dam. The breach occurred in line with the primary spillway barrel, and breach sides are near vertical, indicating a piping failure that likely occurred after water level had receded from overtopping.
