Summary

The dam stands at a height of 34 feet and stretches 550 feet in length, creating a reservoir with a storage capacity of 378 acre-feet. Situated on the Little Mulberry River, the dam poses a high hazard potential but was deemed to be in satisfactory condition during its last inspection in March 2017.

Managed by the Georgia SAFE DAMS program, Mulberry Lake Dam is subject to state regulation, inspection, and enforcement, ensuring its continued safety and compliance with standards. Despite its moderate risk assessment, the dam has not required any major modifications or emergency action plans as of the last assessment date. With its uncontrolled spillway and outlet gates, the dam provides recreational opportunities and helps regulate water flow in the area, contributing to the local ecosystem and water resource management efforts.

As a focal point for water enthusiasts and climate advocates, Mulberry Lake Dam serves as both a recreational attraction and a crucial infrastructure component in the region. With its strategic location on the Little Mulberry River, the dam plays a vital role in flood control and water storage, highlighting the importance of sustainable dam management practices in the face of changing climate conditions.

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.
