Summary

The dam, with a height of 12 feet, serves the purpose of providing a storage capacity of 54 acre-feet. Classified as an Earth dam with a Buttress core type, it features an uncontrolled spillway and has been deemed to have a low hazard potential. The dam is regulated by the Mississippi Department of Environmental Quality, with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.

Despite its moderate risk assessment rating, Marlin Lake Dam has not been assigned a Dam Safety Action Classification (DSAC) date, and its condition assessment remains unrated. Emergency action plans and inundation maps have not been prepared for the dam, highlighting potential areas for improvement in emergency preparedness. However, the dam's risk management measures are currently unspecified, leaving room for further evaluation and potential enhancement of safety protocols.

In conclusion, Marlin Lake Dam stands as a recreational asset in Mississippi, providing storage for water resources and leisure opportunities for visitors. With oversight from the state regulatory agency, the dam's functionality and safety are monitored, though certain aspects such as emergency preparedness could benefit from further attention. As water resource and climate enthusiasts, it is important to stay informed about the condition and management of dams like Marlin Lake Dam to promote sustainable water usage and resilience in the face of changing climate patterns.

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.
