Summary

The dam, primarily constructed for irrigation purposes, has a storage capacity of 120 acre-feet and a normal storage of 54 acre-feet. With a surface area of 15 acres, the dam is classified as an Earth type structure with a Buttress core.

Although the dam has a low hazard potential and is not currently rated for condition assessment, it has been inspected periodically, with the last inspection conducted in July 2015. The risk assessment for Ellerbee Lake Dam is moderate, indicating a level 3 risk. Despite being privately owned, the dam falls under state jurisdiction in Georgia and is subject to state inspections, with no federal regulatory involvement.

Water resource and climate enthusiasts may find Ellerbee Lake Dam intriguing due to its design and purpose, contributing to irrigation in the region. The dam's location in Turner County, Georgia, along with its moderate risk assessment, highlights the importance of maintaining and managing water resources in the face of changing climate conditions. Visitors interested in the intersection of water management, infrastructure, and environmental risk may find Ellerbee Lake Dam a fascinating case study.

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.
