Summary
Built in 1970, the dam stands at a height of 9 feet and spans a length of 880 feet, creating a reservoir with a storage capacity of 170 acre-feet for recreational purposes. Situated on the Caw Caw Swamp, the dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC) with state jurisdiction and permitting in place.
Despite its low hazard potential, the dam's condition assessment is rated as poor, with the last inspection conducted in July 2017. The dam's emergency action plan (EAP) status is not specified, and there are no inundation maps prepared or risk management measures outlined. The dam is not under the jurisdiction of the US Army Corps of Engineers, and it is primarily used for recreational activities in the area. With its historical significance and importance for water resource management in the region, continued monitoring and maintenance of Wannamaker Pond 1 Dam are critical to ensuring its safety and longevity.

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.
