Summary
The dam, primarily funded and regulated by the Mississippi Department of Environmental Quality, was completed in 1962 and stands at a height of 30 feet with a hydraulic height of 25 feet. With a maximum storage capacity of 4200 acre-feet and a normal storage capacity of 2800 acre-feet, the dam plays a vital role in managing water levels and preventing potential flooding in the area.
The dam's spillway type is uncontrolled, with a width of 22 feet, and it has a hazard potential rated as high, alongside an unsatisfactory condition assessment as of May 2020. Despite these challenges, the dam's risk assessment is considered moderate, with ongoing risk management measures in place. The surrounding area covers 227 acres with a drainage area of 4.6 square miles, highlighting the significant impact the Long Creek Reservoir Dam has on water resource management and climate resilience in the region. For water resource and climate enthusiasts, this dam represents a key piece of infrastructure in safeguarding the community against potential flood risks.
As a local government-owned structure, the Long Creek Reservoir Dam stands as a testament to the importance of effective water resource management and infrastructure maintenance. With regular inspections and state enforcement ensuring its functionality, the dam continues to play a crucial role in flood risk reduction efforts in Lauderdale, Mississippi. Its strategic location and design underscore the significance of proactive measures in addressing climate-related challenges and protecting communities from potential water-related hazards.

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.
