Summary
This private dam on Whites Creek stands at 12 feet high and spans 1500 feet in length, providing storage of 631 acre-feet of water for its surrounding area. Despite its age, the dam has a significant hazard potential and is currently assessed as being in poor condition.
Managed by the South Carolina Department of Health and Environmental Control, Wallace Pond Dam is subject to state regulation and inspection to ensure public safety. The dam's emergency action plan was last revised in June 2019, highlighting the importance of preparedness in the event of a potential failure. With a designated inspection frequency of 3 years, efforts are being made to monitor and maintain the dam to mitigate risks and safeguard the local community.
As a key feature on Whites Creek, Wallace Pond Dam offers both recreational opportunities and essential water storage for the region. While facing challenges in its condition assessment, the dam remains a significant part of South Carolina's water resource infrastructure, underscoring the importance of ongoing maintenance and risk management in preserving its functionality and safety.

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.
