Summary
This Earth-type dam, with a height of 25 feet and a length of 2000 feet, plays a crucial role in controlling water levels and ensuring the safety of surrounding areas. However, recent assessments have categorized the dam as having a high hazard potential and poor condition, emphasizing the need for regular inspections and maintenance to mitigate risks.
The dam's primary purpose and design as an Earth dam with a buttress core underscore its importance in water storage and flood control. With a storage capacity of 1013 acre-feet and a normal storage of 315 acre-feet, Mantee Lake Dam serves as a key component in managing water resources in the area. Despite its critical role, the dam's current condition assessment and hazard potential highlight the importance of continued monitoring and potential rehabilitation efforts to ensure its long-term effectiveness and safety for the community.
Located in Webster, Mississippi, Mantee Lake Dam falls under state regulation and oversight by the Mississippi Department of Environmental Quality. Its proximity to the city of Mantee underscores its significance for local residents and the importance of maintaining its structural integrity to safeguard against potential risks and ensure sustainable water resource management in the region. As climate change impacts continue to affect water resources, the management and maintenance of dams like Mantee Lake Dam become increasingly crucial for adapting to changing conditions and ensuring water security for the future.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
