Summary
Lake Dam #2, also known as Dubarco South Lake Dam, is a private dam located in Decatur, Georgia. Built in 1950 for recreational purposes, this earth dam stands at a height of 21.8 feet with a hydraulic height of 18.4 feet. It has a storage capacity of 56 acre-feet and covers a surface area of 7 acres, serving as a popular spot for outdoor activities and water recreation.
Although the dam is classified as low hazard potential with a moderate risk assessment rating, it has not been inspected since October 2002. The lack of recent inspection data raises concerns about its current condition and safety measures in place. Despite being unregulated by the state, its presence in the Savannah District underscores the importance of monitoring and maintaining the structural integrity of dams to prevent potential hazards and ensure the safety of surrounding communities and ecosystems.
With limited information available on its condition assessment and emergency action plan preparedness, Coastal Lumber Co. Lake Dam #2 highlights the need for regular inspections and risk management measures to mitigate any potential threats. Its location in a densely populated area further emphasizes the importance of proactive maintenance and monitoring to safeguard water resources and address climate-related challenges effectively. As a critical infrastructure asset, this dam serves as a reminder of the interconnectedness between water resources management and climate resilience in the face of evolving environmental threats.

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.
