Summary

The dam, designed by James Yagadics of Mayes, Sudderth & Etheredge, Inc., serves as a vital structure for flood control and water resource management in the area. Despite being unlisted on federal databases, the dam has a low hazard potential and a moderate risk assessment rating.

Located in Fulton County, the Lafitte Lake Dam is not regulated by the state but undergoes regular inspections to ensure its structural integrity. The dam features an uncontrolled spillway and outlet gates, with a primary purpose of water storage and management. With a designer who is a reputable figure in the field, the dam stands as a testament to effective engineering practices in ensuring water security and climate resilience in the region.

Although the dam has not been rated for its condition assessment, its risk management measures and emergency preparedness are essential components in safeguarding the surrounding community from potential hazards. With a moderate risk assessment rating and a low hazard potential, Lafitte Lake Dam stands as a reliable structure for water resource management and flood control in the region. Enthusiasts of water resources and climate resilience can appreciate the significance of this dam in maintaining the balance between human development and environmental sustainability.

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.
