Summary
Owned by the local government and designed by USDA NRCS, this earth dam with a height of 25 feet provides a storage capacity of 143 acre-feet. Despite being uncontrolled, the dam's hazard potential is rated as low, with a moderate risk assessment score of 3.
Managed by the Mississippi Department of Environmental Quality, the dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. With a buttress core type and soil foundation, the Greasy Watershed Structure Lt-1a-13 Dam plays a vital role in protecting the surrounding area from potential flooding events. Its location, design, and purpose make it a key component of water resource management in the region, contributing to the overall resilience of the watershed and climate adaptation efforts in the area.
As water resource and climate enthusiasts, understanding the role of structures like the Greasy Watershed Structure Lt-1a-13 Dam is crucial in managing water resources effectively and mitigating the impacts of extreme weather events. By recognizing the importance of flood risk reduction measures and the regulatory framework in place, we can work towards a more sustainable and resilient future for our water systems and communities.

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.
