Summary
Completed in 1949, this dam stands at a height of 20 feet and has a storage capacity of 160 acre-feet, making it a vital resource for water management in the area. The dam spans 530 feet in length and covers a surface area of 23.5 acres, serving as a popular spot for outdoor enthusiasts to enjoy activities such as fishing and boating.
Managed by the Mississippi Department of Environmental Quality, Pennington Lake Number 4 Dam is inspected regularly to ensure its structural integrity and safety. With a high hazard potential but a fair condition assessment as of August 2019, the dam's risk assessment is categorized as moderate. In the event of an emergency, the dam's emergency action plan is in place to mitigate risks and protect surrounding communities, although details on its last revision date and adherence to guidelines are not specified. Overall, Pennington Lake Number 4 Dam is a key feature in the local landscape, supporting both recreational opportunities and water resource management efforts in the region.

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.
