This concrete gravity dam serves primarily as a water supply source, with a storage capacity of 11,610 acre-feet and a normal storage level of 9,600 acre-feet. The dam, standing at 70 feet tall and spanning 360 feet in length, also supports recreational activities along the Savannah River.
Despite its age and deteriorating condition, a risk assessment conducted by the USACE in 2014 classified the dam's risk of failure as low due to its limited downstream impacts. However, the structure displays signs of aging, with significant cracking in the spillway piers and erosion around the lock wall base. USACE actively manages these risks through regular inspections, emergency preparedness measures, and ongoing training to ensure the safety and stability of the dam.
While the consequences of a potential failure are deemed relatively minimal, the USACE remains vigilant in monitoring and maintaining the New Savannah Bluff Lock and Dam to mitigate any risks. Through collaboration with local emergency managers, updated emergency action plans, and periodic training for project personnel, the USACE is committed to ensuring the continued safe operation of this critical water resource infrastructure.
