Summary
Built in 1973, this earth dam stands at 20 feet high and stretches 410 feet in length, providing a storage capacity of 80 acre-feet. Despite its recreational value, the dam is categorized as having a significant hazard potential and a poor condition assessment, making it a subject of concern for water resource and climate enthusiasts.
Managed by the Mississippi Department of Environmental Quality, Blacks Dam is inspected every five years to ensure its structural integrity and safety. The dam's spillway, with a width of 3 feet, is uncontrolled, posing potential risks in case of heavy rainfall or flooding events. While the risk assessment for the dam is moderate, the condition assessment highlights the need for maintenance and potential improvements to mitigate hazards and enhance long-term sustainability.
Given its location on the UNT of Little Bogue Homo river, Blacks Dam plays a vital role in managing water resources and providing recreational opportunities for the community. With ongoing inspections and risk management measures, there is a concerted effort to address the dam's poor condition and ensure its continued functionality in the face of changing climate conditions. As water resource and climate enthusiasts, staying informed and advocating for the proper maintenance and management of dams like Blacks Dam is crucial to safeguarding our natural resources and infrastructure.

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.
