Summary
Built in 1963 by the USDA NRCS, this dam serves primarily for flood risk reduction along the TR- Fannegusha Creek. With a height of 30 feet and a storage capacity of 1718 acre-feet, this structure plays a crucial role in managing water flow in the area.
The dam is regulated by the Mississippi Department of Environmental Quality and undergoes regular state inspections and enforcement to ensure its safety and functionality. Despite being classified as having a low hazard potential, the dam's risk assessment is moderate due to its age and condition not being rated. The spillway type is uncontrolled, with uncontrolled outlet gates, indicating a simpler structure designed to manage water flow without complex control mechanisms.
For water resource and climate enthusiasts, Black Watershed Structure Y-36-12 Dam presents an interesting case study of a locally owned flood risk reduction infrastructure in Mississippi. With its historical significance and role in managing water flow along the TR- Fannegusha Creek, this earth dam showcases the importance of proactive maintenance and regulation to ensure the safety and effectiveness of such structures in mitigating the impacts of extreme weather events and climate change 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.
