Summary
With a low hazard potential and a moderate risk assessment, this earth and buttress dam provides a safe and enjoyable environment for water enthusiasts. Managed by the Mississippi Department of Environmental Quality, the dam is state-regulated, permitted, inspected, and enforced to ensure its structural integrity and operational efficiency.
Standing at a height of 20 feet, the Diamond D Lake Dam has a storage capacity of 448 acre-feet, making it a significant reservoir for water resources in the area. Its uncontrolled spillway type ensures controlled water release during periods of excess volume, safeguarding the surrounding ecosystem from potential flooding. With a primary purpose of recreation, the dam offers a serene retreat for locals and visitors alike, with ample opportunities for boating, fishing, and other water-based activities.
While the dam's condition assessment is currently not rated, its risk management measures are in place to address any potential issues that may arise. With a designated emergency action plan and updated contact information, the Diamond D Lake Dam is well-prepared to handle any unforeseen events. As a crucial part of the water infrastructure in Mississippi, this dam serves as a testament to the state's commitment to water resource management and climate resilience.

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.
