Summary
Standing at a height of 20 feet and with a storage capacity of 198 acre-feet, this dam offers a serene surface area of 12 acres for visitors to enjoy. Despite its uncontrolled spillway and outlet gates, the dam has a low hazard potential and a moderate risk assessment rating.
Owned privately and not regulated by the state, Post Road Lake Dam has not undergone recent assessments for its condition and emergency action plans. However, it has been inspected as of November 2018, with an inspection frequency of every five years. The dam's risk management measures and risk characterization summary have not been specified, indicating a potential area for improvement in ensuring the safety and integrity of this recreational water resource.
With its picturesque location and modest risk assessment, Post Road Lake Dam presents an opportunity for water resource and climate enthusiasts to appreciate the beauty of nature while also advocating for sustainable dam management practices. As a private structure with limited regulatory oversight, there is room for increased monitoring and assessment to ensure the long-term safety and functionality of this recreational gem in Jasper County, Georgia.

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.
