Summary

Built in 1948 by designer John Holiday, this Earth dam stands at a height of 19.6 feet and has a maximum storage capacity of 58 acre-feet. The dam, with a length of 282 feet, is classified as having a low hazard potential and a moderate risk assessment.

Although Foster Lake Dam is not regulated by the state and does not have a designated agency for inspection or enforcement, it serves as an important source of water storage in the region. The dam's uncontrolled spillway and outlet gates contribute to its recreational purpose, providing a surface area of 5.5 acres for various water activities. While the dam's condition is currently rated as "Not Rated," its risk management measures and emergency action plan status remain unknown.

For water resource and climate enthusiasts, Foster Lake Dam offers a fascinating example of a privately owned recreational dam in Georgia. Its historical significance, design characteristics, and risk assessment provide valuable insights into the intersection of water management, environmental conservation, and public safety in the region. As a key feature in the local landscape, Foster Lake Dam invites further exploration and study for those interested in understanding the dynamics of dam infrastructure and its impact on surrounding communities.

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.
