Summary
Constructed in 1965 by USDA NRCS, this structure serves the primary purpose of flood risk reduction along TR-Black Creek. With a height of 33 feet and a NID storage capacity of 574 acre-feet, the dam helps regulate water flow and reduce the risk of flooding in the area.
Managed by the Mississippi Department of Environmental Quality, Black Watershed Structure Y-36-28 Dam is state-regulated and undergoes regular inspections and enforcement measures to ensure its safety and functionality. With a low hazard potential and a moderate risk assessment score of 3, the dam plays a crucial role in mitigating flood risks in the region. Although the condition assessment is currently not rated, the dam's construction, design, and purpose highlight its importance in water resource management and climate resilience efforts in the area.
Overall, Black Watershed Structure Y-36-28 Dam stands as a key infrastructure asset in flood risk reduction efforts in Holmes County, Mississippi. With its controlled spillway and uncontrolled outlet gates, the dam helps manage water flow and protect surrounding communities from potential inundation. As climate change continues to impact water resources, structures like this play a critical role in safeguarding local ecosystems and infrastructure from the effects of extreme weather events, highlighting the importance of sustainable water management practices 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.
