Summary
This private-owned earth dam stands at a height of 19 feet and stretches 620 feet in length, with a storage capacity of 117 acre-feet and a surface area of 10 acres. Despite its historical significance, the dam's condition assessment is rated as poor, with a low hazard potential and moderate risk level.
Managed by the South Carolina Department of Health and Environmental Control (DHEC), Johnsons Pond Dam is state-regulated and undergoes regular inspections to ensure compliance with safety standards. The dam's primary purpose is for recreation, attracting visitors to enjoy the waters of Jordon Creek. However, with a risk assessment rating of moderate and a history of poor condition, there may be a need for increased risk management measures to maintain the safety and integrity of the structure. For water resource and climate enthusiasts, monitoring the ongoing maintenance and potential updates to Johnsons Pond Dam can provide valuable insight into the intersection of environmental preservation and recreational activities.

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.
