Summary

Built in 1939, this earth dam stands at a height of 32.1 feet and spans a length of 348 feet, with a storage capacity of 76.7 acre-feet. Despite its age, the dam is in satisfactory condition and has a high hazard potential, prompting regular inspections every two years to ensure its safety.

Managed by the Georgia Safe Dams Program, Peppertree Lake Dam poses a moderate risk of failure, prompting the need for ongoing risk assessment and management measures. While the dam features uncontrolled spillways and outlet gates, its overall structural integrity remains intact. The dam's surrounding area covers a surface area of 4 acres and drains from a 101-acre watershed, making it an essential water resource for the local community.

With its history dating back over 80 years, Peppertree Lake Dam serves as a vital recreational site in Sandy Springs, Georgia. Despite its age and high hazard potential, the dam continues to provide valuable storage and water management capabilities within the region. As water resource and climate enthusiasts, it's crucial to monitor and support the ongoing maintenance and safety efforts for structures like Peppertree Lake Dam to ensure sustainable water management practices for future generations.

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.
