Summary
Constructed by the Soil Conservation Service (SCS), this private dam serves a vital purpose in regulating water flow and storage. With a low hazard potential and a moderate risk assessment, the dam boasts a height of 17 feet and a storage capacity of 98 acre-feet, making it a crucial component of the local water infrastructure.
Located in the Mobile District of Georgia, Johnson Lake Dam is primarily an earth dam with buttress core types. It features an uncontrolled spillway and outlet gates, reflecting its design for efficient water discharge. While the dam has not been rated for its condition, its risk management measures are in place to ensure the safety of the surrounding area. With a history dating back to the completion year unknown, Johnson Lake Dam continues to play a key role in water resource management and climate resilience efforts in the region.
As water resource and climate enthusiasts explore the significance of Johnson Lake Dam, its role as a private entity owned and managed dam in Georgia becomes clear. With no state regulation or permitting in place, the dam stands as a testament to private ownership's responsibility in ensuring water safety and security. As it continues to fulfill its purpose in water storage and flow regulation, Johnson Lake Dam serves as a vital asset in the region's water infrastructure, embodying the importance of sustainable water management practices for future generations.

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.
