Summary

Built in 1965, this earth dam stands at a height of 26 feet and has a storage capacity of 735 acre-feet, serving a drainage area of 1438 acres. With a high hazard potential, the dam's condition was assessed as satisfactory during its last inspection in January 2017.

Owned by the state of Georgia and regulated by the GA-SAFE DAMS PROGRAM, Marbury Creek WS Str # 22 is designed by the Natural Resources Conservation Service. The dam features an uncontrolled spillway and outlet gates, emphasizing flood risk reduction as its primary purpose. Despite its moderate risk assessment, the structure has not been modified in recent years and is subject to biennial inspections to ensure its continued effectiveness in mitigating flood events.

Located in Barrow County, Marbury Creek WS Str # 22 is a significant asset in the region's water management infrastructure, providing valuable protection against potential flooding. As climate change continues to impact weather patterns, structures like this play a crucial role in safeguarding communities and ecosystems from the increasing threats of extreme weather events. With its strategic design and maintenance, this dam exemplifies the importance of proactive water resource management in the face of a changing climate.

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.
