Summary
With a height of 28 feet and a storage capacity of 128 acre-feet, this earth dam plays a crucial role in protecting the surrounding area from potential flooding events. Despite being classified as having a low hazard potential, the dam's condition assessment is currently listed as "Not Rated," indicating a need for further evaluation.
Owned and regulated by the Mississippi Department of Environmental Quality, this dam is subject to state permitting, inspection, and enforcement protocols. The primary purpose of the Greasy Watershed Structure Lt-1a-02 Dam is flood risk reduction, aligning with its design and construction as an earth dam with a buttress core type. While the dam's risk assessment is considered moderate, with a score of 3, there is currently no Emergency Action Plan in place, highlighting a potential area for improvement in terms of emergency preparedness.
Overall, the Greasy Watershed Structure Lt-1a-02 Dam serves as a critical infrastructure in the region, safeguarding against flooding and protecting the local community. With its regulated state jurisdiction and adherence to safety measures, this dam stands as a testament to the importance of water resource management and climate resilience in the face of changing environmental conditions. As water resource and climate enthusiasts, the ongoing monitoring and maintenance of this dam present an opportunity for further study and engagement in the intersection of water management and environmental protection.

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.
