Summary
This earth dam stands at a height of 45 feet and spans a length of 400 feet, providing a storage capacity of 132 acre-feet. Completed in 1968, the dam overlooks the scenic Sage Mill Branch, offering a surface area of 20 acres for outdoor activities such as fishing, boating, and picnicking.
Despite its low hazard potential, the dam is regulated and inspected by the South Carolina Department of Health and Environmental Control (DHEC) to ensure its safety and compliance with state standards. The last inspection conducted in August 2017 found the dam to be in a "Not Rated" condition, indicating the need for further assessment. With a designated emergency action plan and updated contact information, the Graniteville CO Dam 1 serves as a vital infrastructure for both recreational enjoyment and water resource management in the region.
As an integral component of the local landscape, the Graniteville CO Dam 1 stands as a testament to responsible water resource management and environmental stewardship. With its commitment to safety and regulatory compliance, this earth dam continues to provide a valuable recreational space for residents and visitors alike, while also ensuring the protection of surrounding areas from potential flooding events. As climate change impacts water resources, structures like the Graniteville CO Dam 1 play a crucial role in maintaining the balance between human needs and natural ecosystems.

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.
