Summary
Completed in 1964, this earth dam stands at a height of 38 feet and stretches 622 feet in length, with a storage capacity of 1670 acre-feet. Despite its low hazard potential and satisfactory condition assessment, the dam is regulated by the Mississippi Department of Environmental Quality, ensuring regular inspections and enforcement of safety measures.
Owned by the local government, Black Creek WS Str Y-36-56 Dam plays a crucial role in protecting the surrounding area from potential flooding, with a drainage area of 4.35 square miles. The dam's uncontrolled spillway type and outlet gates demonstrate its reliance on natural discharge mechanisms, while its moderate risk assessment rating reflects the ongoing management measures in place to mitigate any potential hazards. With a history of regular inspections and compliance with state regulations, this dam stands as a testament to effective collaboration between government agencies and environmental conservation efforts in Mississippi.
For water resource and climate enthusiasts, Black Creek WS Str Y-36-56 Dam offers a fascinating case study in dam infrastructure management and flood control strategies. Situated within the Vicksburg District and overseen by the Natural Resources Conservation Service, this earth dam stands as a testament to sustainable engineering practices and the importance of ongoing monitoring and maintenance to ensure the safety and integrity of water resource structures. As climate change continues to pose challenges to water management systems, the lessons learned from dams like Black Creek WS Str Y-36-56 Dam serve as valuable insights into the intersection of infrastructure, environmental protection, and community resilience in the face of a changing climate.

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.
