Summary
Constructed in 1965 by USDA NRCS, this earth dam stands at a height of 33 feet and has a storage capacity of 548 acre-feet. The dam is designed to regulate the flow of TR-Black Creek and is under the regulatory oversight of the Mississippi Department of Environmental Quality.
With a low hazard potential and a moderate risk assessment rating, Black Watershed Structure Y-36-24 Dam plays a crucial role in protecting the surrounding areas from potential flooding events. Despite being uncontrolled, the dam's spillway and outlet gates ensure the safe release of excess water during heavy rainfall periods. While the condition assessment is currently not rated, the dam remains a key asset in the state's flood risk management strategy.
As a significant piece of infrastructure in the Vicksburg District, Black Watershed Structure Y-36-24 Dam serves as a reminder of the importance of water resource management and climate resilience. Its presence highlights the collaborative efforts between local government authorities, regulatory agencies, and federal designers in safeguarding communities against the impacts of extreme weather events.

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.
