Summary
The dam, with a height of 18 feet and a length of 375 feet, impounds Beaverdam Creek, providing storage of up to 60 acre-feet of water. Despite its low hazard potential, the dam's condition assessment is rated as poor, with the last inspection taking place in October 2017.
Managed by the South Carolina Department of Health and Environmental Control (DHEC), the dam is subject to state regulation, permitting, inspection, and enforcement. While the dam's purpose is for recreation, its poor condition raises concerns about its long-term safety and maintenance. The surrounding area offers six acres of surface water for recreational activities, making it a popular spot for water resource and climate enthusiasts.
With its unique design as an earth dam with a buttress core type, James and John Henderson Dam presents both a picturesque recreational opportunity and a potential challenge for ongoing maintenance and risk management. The presence of a low hazard potential warrants attention to address the poor condition assessment and ensure the safety of the dam for both recreational users and the surrounding environment.

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.
