Summary

Built in 1958, this earth dam stands at a height of 32.2 feet and has a length of 210 feet, creating a reservoir with a storage capacity of 45 acre-feet. The dam is classified as a high hazard potential structure with a poor condition assessment, last inspected in February 2016.

Despite its recreational use, Tera Lee Lake Dam poses a moderate risk, with a risk assessment rating of 3 out of 5. The dam features an uncontrolled spillway and outlet gates, indicating potential issues with water discharge management. The structure is regulated by the Georgia Safe Dams Program, with state jurisdiction, permitting, inspection, and enforcement in place to ensure compliance and safety.

Water resource and climate enthusiasts interested in Tera Lee Lake Dam may find the structure's design and operational details intriguing. With its location in Sandy Springs, Georgia, this dam provides valuable insights into the management of water resources and infrastructure maintenance in the region. Further monitoring and maintenance efforts are essential to address the poor condition assessment and ensure the safety of the dam and surrounding areas for recreational users and residents alike.

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.
