Summary
This earth dam, with a height of 34 feet and a length of 452 feet, serves the primary purpose of mitigating flood risks in the area by controlling the flow of the UNT of Lofomby River. With a storage capacity of 255 acre-feet and a drainage area of 0.27 square miles, the dam plays a crucial role in managing water resources in the region.
Owned by the local government and regulated by the Mississippi Department of Environmental Quality, this dam has a low hazard potential and a moderate risk assessment. While it is currently in "Not Rated" condition, the dam has not undergone recent inspections or condition assessments. Despite this, it continues to fulfill its function in reducing flood risks and protecting the surrounding community. The dam's uncontrolled spillway and outlet gates, as well as its soil foundation, contribute to its overall effectiveness in managing water flow and potential emergencies.
As water resource and climate enthusiasts, the Greasy Watershed Structure Lt-1a-15 Dam serves as a focal point for understanding the intersection of infrastructure, environmental regulation, and community safety. Its historical significance, design features, and operational parameters provide valuable insights into the management of water resources and the importance of proactive risk assessment and maintenance of critical infrastructure. By examining this dam's characteristics and functions, we can deepen our appreciation for the complex interplay between human interventions and natural systems in shaping our water landscape.

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.
