Summary
This earth dam stands at a height of 30 feet and has a storage capacity of 225 acre-feet. Despite its low hazard potential, the dam is regulated by the Mississippi Department of Environmental Quality and undergoes regular inspections to ensure its structural integrity.
Owned by the local government, the Greasy Watershed Structure Lt-1a-01 Dam plays a vital role in protecting the surrounding Panola County from potential flooding events. With a primary purpose of flood risk reduction, the dam has an uncontrolled spillway type and outlet gates. While it is not currently rated for its condition, the dam is considered to have a moderate risk level, prompting the need for ongoing risk management measures to be implemented.
The dam, designed by the Natural Resources Conservation Service, is an essential component of the water resource management infrastructure in the area. With its strategic location and design features, the Greasy Watershed Structure Lt-1a-01 Dam stands as a testament to the importance of proactive climate adaptation and disaster risk reduction efforts in safeguarding communities and ecosystems against the impacts of extreme weather events.

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.
