Summary
Managed by a private owner, the dam stands at a height of 25 feet with a structural height of 23 feet, stretching 350 feet in length. With a maximum storage capacity of 317 acre-feet and a normal storage of 160 acre-feet, the dam covers a surface area of 20 acres.
Designed by the Natural Resources Conservation Service, the dam is primarily of earth type with a buttress core, serving as a key element for water resource management in the region. Despite its low hazard potential, the dam's risk assessment indicates a moderate level of risk (3). While the last inspection in 2014 found the dam to be in a condition not rated, the structure is under regular inspection with a frequency of every 5 years to ensure its safety and functionality.
Located at 33.022222 latitude and -82.069722 longitude, the Jenkins - Johnson Lake Dam plays a vital role in ensuring water security and environmental sustainability in the area. As an enthusiast of water resources and climate management, this dam presents a fascinating case study in the intersection of infrastructure development, ecological conservation, and risk mitigation.

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.
