Summary

Built in 1966 by the USDA NRCS, this earth-type dam serves primarily for irrigation purposes, with a storage capacity of 132 acre-feet. The dam stands at a height of 19 feet and spans 205 feet in length, creating a surface area of 10 acres for recreational activities.

Managed by the South Carolina Department of Health and Environmental Control, the dam is regulated, inspected, and enforced to ensure its safety and functionality. Despite its fair condition assessment in 2017, the dam has a low hazard potential, with a moderate risk assessment rating. The dam's spillway is uncontrolled, and it has an uncontrolled outlet gate system, posing minimal risk to downstream communities in the event of an emergency.

With its picturesque location on Wilson Creek, Abner Stockman Dam not only provides essential irrigation water but also offers a serene recreational space for visitors to enjoy. As a vital piece of water infrastructure in the region, the dam is a testament to the importance of sustainable water resource management and climate resilience efforts in South Carolina.

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.
