Summary

Completed in 1973, this earth dam stands at a height of 32 feet and has a length of 400 feet, creating a reservoir with a storage capacity of 886 acre-feet. The dam's primary purpose is for recreation, providing a surface area of 36 acres for various water activities.

Despite its recreational benefits, Robbins Lake Dam poses a high hazard potential and has been deemed unsatisfactory in its condition assessment as of June 2020. The dam is state-regulated by the Mississippi Department of Environmental Quality, with regular inspections conducted to ensure public safety. The risk assessment for the dam indicates a moderate risk level, highlighting the importance of ongoing monitoring and management measures.

As water resource and climate enthusiasts, it is crucial to recognize the significance of maintaining and safeguarding dams like Robbins Lake Dam to mitigate potential risks and ensure the sustainable use of water resources. With its strategic location and recreational value, this dam serves as a focal point for both enjoyment and environmental responsibility in the local community.

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.
