Summary

This privately owned earth dam stands at a height of 32 feet and has a length of 840 feet, with a storage capacity of 235 acre-feet. While the dam is primarily used for water supply purposes, it also helps regulate water flow through an uncontrolled spillway and outlet gates.

Despite being classified as low hazard potential, the dam has a moderate risk assessment rating. Its condition is currently not rated, and it has not undergone recent inspections or maintenance. The dam's risk management measures and emergency action plan status are also unclear. With its location in a growing area like Henry County, ensuring the safety and stability of Hardeman Lake Dam is crucial to protect the surrounding community and water resources.

Water resource and climate enthusiasts interested in the infrastructure and management of dams will find Hardeman Lake Dam's details intriguing. From its construction history to its current risk assessment and emergency preparedness status, this dam highlights the importance of proactive maintenance and monitoring to safeguard water resources and communities in Georgia. As climate change continues to impact water availability and quality, understanding and addressing the risks associated with dams like Hardeman Lake Dam are vital for sustainable water management practices.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
