Summary
This Earth dam, completed in 1900, serves primarily for recreational purposes and stands at a height of 10 feet with a length of 690 feet. The dam has a storage capacity of 1140 acre-feet, with a normal storage level of 240 acre-feet and a surface area of 150 acres.
Despite its low hazard potential and fair condition assessment, Bostwick Pond Dam 3 is subject to state regulation, inspection, and enforcement by the South Carolina Department of Health and Environmental Control (DHEC). The dam is situated on the TR-Huspa Creek in the Savannah District and is under the jurisdiction of the state for permitting and regulatory purposes. While the risk assessment indicates a very high risk level, the dam has not been modified in recent years and lacks certain emergency preparedness features such as an Emergency Action Plan (EAP) and inundation maps.
Overall, Bostwick Pond Dam 3 represents an important water resource structure in South Carolina, providing recreational opportunities while also being subject to state oversight and regulation. Climate and water resource enthusiasts may find interest in the historical significance of this dam, its design features, and the ongoing efforts to manage its risk level and ensure public 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.
