Summary
Completed in 1968, this earth dam stands at a height of 39.5 feet and has a maximum storage capacity of 1631 acre-feet, serving the primary purpose of flood risk reduction along Wolf Creek. Managed by the Georgia-SAFE Dams Program, this state-regulated structure is inspected biennially to ensure its satisfactory condition and high hazard potential.
With a drainage area of 1931 acres and a normal storage capacity of 216 acre-feet, Rc&D Watershed Structure Y-14 plays a crucial role in managing water resources and mitigating flood risks in the region. The dam, designed by SCS and owned by the state, is equipped with uncontrolled spillways and outlets gates to handle excess water flow during peak discharge events. Despite its moderate risk assessment rating, the structure has been deemed to meet regulatory guidelines and is actively monitored for any necessary risk management measures.
As water resource and climate enthusiasts, understanding the significance of structures like Rc&D Watershed Structure Y-14 is essential in safeguarding communities and ecosystems from potential flooding disasters. With a focus on sustainable water management and infrastructure resilience, it is crucial to support efforts in maintaining and improving such critical facilities to ensure the safety and well-being of all those who rely on them for flood protection and water resource management.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
