Summary
This earth dam, with a height of 28 feet and a storage capacity of 204 acre-feet, is primarily owned and regulated by the local government and the Mississippi Department of Environmental Quality. Despite being classified as low hazard potential, the dam's condition remains unrated, highlighting the need for ongoing monitoring and maintenance to ensure its continued effectiveness in mitigating flood risks.
The dam's design features a buttress core and is founded on soil, with an uncontrolled spillway and outlet gates. While the dam has not been modified in recent years and has no associated locks, it plays a vital role in managing the drainage area of 0.56 square miles. With a moderate risk assessment rating of 3 out of 5, there is a need for proactive risk management measures to be put in place to address potential vulnerabilities. The dam's location in Batesville, Mississippi, underscores its importance in protecting the surrounding community from flood events and highlights the collaborative effort between local and state agencies in ensuring its functionality and safety.
Overall, the Greasy Watershed Structure Lt-1a-03 Dam stands as a critical infrastructure asset for flood risk reduction in Lafayette County, Mississippi. With its historic significance dating back to the 1960s, the dam continues to play a vital role in managing water resources and protecting the local community from potential flood hazards. As climate change continues to impact weather patterns and increase the frequency of extreme events, the importance of maintaining and monitoring this dam to uphold its resilience and effectiveness in safeguarding the surrounding area becomes increasingly apparent.

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.
