Summary

This earth dam, standing at 36 feet tall and stretching 455 feet in length, holds a storage capacity of 690 acre-feet along the Sandy Creek. Managed by the Georgia-SAFE DAMS PROGRAM, the dam is regulated, inspected, and enforced by the state to ensure its structural integrity and safety.

With a high hazard potential and a satisfactory condition assessment as of January 2017, Newnan Waterworks Dam # 1 remains a crucial component of the region's water resource management. Despite its uncontrolled spillway and outlet gates, the dam has been deemed to meet guidelines and poses a moderate risk level. The dam's emergency action plan and risk management measures are under constant evaluation to mitigate any potential threats and ensure the safety of nearby communities in case of inundation events.

As water resource and climate enthusiasts, understanding the significance of structures like Newnan Waterworks Dam # 1 is essential for sustainable water management practices. With a focus on water supply and public utility, this dam serves as a lifeline for the community, highlighting the importance of regulatory oversight, regular inspections, and risk assessment protocols in safeguarding our water resources for future generations.

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.
