Summary
Designed by USDA NRCS and completed in 1965, this earth dam with a height of 30 feet serves the primary purpose of mitigating flood risks in the area. The dam has a storage capacity of 617 acre-feet and is regulated by the Mississippi Department of Environmental Quality, ensuring proper inspection, enforcement, and permitting protocols are in place.
Situated on Sugar Creek in Holmes County, Mississippi, the Black Watershed Structure Y-36-43 Dam is owned by the local government and falls under the jurisdiction of the state regulatory agency. With a hazard potential rated as low and a moderate risk assessment score of 3, the dam plays a vital role in managing water resources and protecting the surrounding community from potential flooding events. While the condition assessment is currently not rated, the dam's design and construction by the Natural Resources Conservation Service highlight the commitment to effective water resource management and climate resilience in the region.
Overall, Black Watershed Structure Y-36-43 Dam stands as a significant infrastructure asset in Mississippi, contributing to flood risk reduction efforts and water resource management in the area. With its earth dam structure and uncontrolled spillway type, the dam's functionality and purpose align with the larger goal of safeguarding communities against potential water-related disasters. As water resource and climate enthusiasts, understanding the key role this dam plays in protecting the local environment and enhancing resilience to changing climate conditions is essential for promoting sustainable water management practices and ensuring the safety of residents 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.
