Summary
This earth dam stands at 49 feet high and spans 770 feet, with a storage capacity of 1400 acre-feet. The dam's primary purpose is flood risk reduction, with a low hazard potential and fair condition assessment as of October 2017.
Managed by the South Carolina DHEC, this dam is state-regulated and inspected regularly to ensure its safety and functionality. Despite its low hazard potential, the risk assessment for Rocky Creek WCD Dam 9 indicates a very high risk level, emphasizing the importance of continued monitoring and maintenance. With its controlled spillway and uncontrolled outlet gates, this dam plays a crucial role in protecting the surrounding area from flooding events and showcases the collaborative efforts between local government and private entities in water resource management.
As a key structure in the region's water resource infrastructure, Rocky Creek WCD Dam 9 stands as a testament to the importance of proactive flood risk reduction measures. With its historical completion by the USDA NRCS and ongoing state regulation by the SC DHEC, this dam serves as a model for effective water management practices in the face of climate change challenges. Water resource and climate enthusiasts can appreciate the significance of this dam in safeguarding communities and ecosystems against the impacts of extreme weather events.

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.
