Summary

The dam serves primarily for recreational purposes, providing a storage capacity of 151 acre-feet and a normal storage of 113 acre-feet. The dam, situated on Limestone Creek, features an uncontrolled spillway and outlet gates.

Despite being deemed to have a low hazard potential, the dam's condition has not been rated since its last inspection in 1989. With a risk assessment rating of moderate (3), there is a need for further evaluation and potential risk management measures to ensure the safety and stability of the structure. The dam is privately owned and has not undergone state regulation or permitting.

For water resource and climate enthusiasts, Brenau Lake Dam presents an intriguing case study in dam infrastructure management and the importance of regular inspection and maintenance. As the dam continues to age, there is a growing need for updated assessments and potentially improved risk management measures to mitigate any future hazards or failures that may arise. The dam's location, design, and historical significance make it a valuable site for studying the intersection of water resource management and climate resilience.

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.
