Summary
The dam, standing at a height of 15.8 feet with a hydraulic height of 13.2 feet, has a storage capacity of 141.8 acre-feet and covers a surface area of 14 acres. Despite its low hazard potential and moderate risk assessment rating, the dam is unregulated by the state and lacks official inspections and enforcement measures.
Owned privately, Twin Oaks Plantation Lake Dam is primarily made of earth with a buttress core type and an uncontrolled spillway. The dam's design and construction details remain unknown, reflecting a lack of regulatory oversight and documentation. While the dam's condition assessment is listed as "Not Rated," its last inspection in August 2019 indicated a low hazard potential. The dam's emergency action plan status and risk management measures are also unspecified, raising questions about its safety and preparedness.
With its location in Thomasville, Georgia, Twin Oaks Plantation Lake Dam presents a unique case study for water resource and climate enthusiasts. The dam's historical significance, multi-functional purpose, and lack of regulatory oversight highlight the complexities of managing and maintaining water infrastructure in a changing climate. As efforts to address dam safety and resilience continue to evolve, Twin Oaks Plantation Lake Dam serves as a reminder of the importance of proactive monitoring and maintenance to protect communities and ecosystems from potential risks and impacts.

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.
