Summary

Completed in 1998, this earth-type dam stands at a height of 30 feet with a length of 325 feet. It has a maximum storage capacity of 16.5 acre-feet and a normal storage level of 4 acre-feet, serving the purpose of mitigating potential flood hazards in the area. The dam is situated on TwentyMile Creek, under the jurisdiction of the South Carolina Department of Health and Environmental Control (DHEC), and is regulated, inspected, and enforced by state authorities.

Despite having a low hazard potential, Farming Creek Dam has not been rated for its condition assessment. It features a stone core type with a soil foundation and does not have a spillway. The dam's inspection frequency is set at every five years, with the last assessment conducted in April 2017. While the dam is not maintained by any federal agency, it plays a crucial role in flood risk reduction and offers recreational opportunities for the local community.

Overall, Farming Creek Dam serves as a vital infrastructure for flood control in the region, ensuring the safety and well-being of nearby residents. With its strategic location on TwentyMile Creek and efficient design, the dam continues to fulfill its primary purpose while also providing recreational amenities for visitors. As climate change impacts water resources, structures like Farming Creek Dam play a crucial role in managing the risks associated with extreme weather events and safeguarding the local environment.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
