Summary
Built in 1967, this earth dam stands at a height of 39 feet and has a length of 475 feet, with a storage capacity of 332 acre-feet. Situated on Slatstone Creek, this dam is regulated by the South Carolina Department of Health and Environmental Control (SC DHEC) and undergoes regular inspections to ensure its safety and integrity.
Despite its fair condition assessment and high hazard potential, the 321 Assoc Asc Dam continues to provide valuable recreational opportunities for the local community. The dam's reservoir covers a surface area of 13.9 acres and offers a picturesque setting for activities such as fishing, boating, and wildlife viewing. With a commitment to inspection, enforcement, and permitting, the state of South Carolina maintains a proactive approach to managing this vital water resource in order to mitigate potential risks and protect public safety.
As climate change impacts water resources and infrastructure, the importance of maintaining and regulating dams like the 321 Assoc Asc Dam becomes increasingly evident. By staying informed about the condition of these structures, advocating for necessary upgrades, and promoting responsible water usage, enthusiasts can contribute to the sustainability and resilience of these essential assets in the face of evolving environmental challenges.

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.
