Summary
Built in 1976, this dam stands at a height of 15 feet and stretches 420 feet in length, with a storage capacity of 74 acre-feet. Primarily used for recreation, the dam provides a picturesque setting for outdoor enthusiasts to enjoy activities such as boating, fishing, and picnicking.
Despite its low hazard potential, the dam's condition assessment is rated as poor, with the last inspection conducted in November 2017. The inspection frequency is set at every five years, raising concerns about the structural integrity and maintenance of the dam. With its location in a state-regulated area and under the jurisdiction of SC DHEC, there is a need for ongoing monitoring and potential risk management measures to ensure the safety and functionality of this recreational water resource.
For water resource and climate enthusiasts, R Holliday Lower Dam presents an opportunity to explore the intersection of environmental conservation and recreational enjoyment. As discussions around dam safety and maintenance continue to evolve, understanding the complexities of managing water infrastructure like R Holliday Lower Dam becomes crucial in safeguarding both natural ecosystems and human activities that rely on these resources.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
