The dam's spillway is uncontrolled, and it features outlets gates for water discharge. With a moderate risk assessment rating of 3, the dam's risk management measures, emergency action plans, and inundation maps are all critical components to ensure the safety of the surrounding community in the event of a breach or emergency situation. Overall, Dupont Lake Dam stands as a vital water resource structure in the region, providing both recreational opportunities and essential flood control functions for the Little River-Tr watershed.
