Summary

Built in 1940, this private dam stands at a height of 11.3 feet and has a storage capacity of 159 acre-feet, with a normal storage level of 48 acre-feet. The dam is primarily an earth structure with a buttress core type, providing essential water resources for the surrounding area.

Despite its low hazard potential and moderate risk assessment, Carter Lake Dam has not been rated for its condition. The dam features an uncontrolled spillway and outlet gates, with the last inspection conducted in July 2016. The dam's location in Worth County, Georgia, makes it a critical infrastructure for managing water resources and maintaining ecological balance in the region. Furthermore, its proximity to Jacksonville District adds to its importance in the overall water resource management system.

As a key feature in the local water infrastructure, Carter Lake Dam plays a crucial role in ensuring water availability for fire protection and sustaining aquatic life in the area. Its historical significance, combined with its functional design and moderate risk assessment, highlights the importance of continued monitoring and maintenance to safeguard the surrounding community and environment from potential water resource challenges. For water resource and climate enthusiasts, Carter Lake Dam represents a vital component of Georgia's water management system, contributing to the overall ecological sustainability of the region.

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.
