Summary
Completed in 1970, the dam serves primarily as a flood risk reduction measure along the Coon Creek. Designed by the USDA NRCS, this earth dam stands at a height of 25 feet and spans a length of 1423 feet, with a storage capacity of 2692 acre-feet.
Managed and regulated by the Mississippi Department of Environmental Quality, Coon Creek Lake Dam has a low hazard potential and its condition was last assessed as unsatisfactory in May 2014. Despite this, the dam continues to play a crucial role in protecting the surrounding area from flooding, with a normal storage capacity of 298 acre-feet and a surface area of 99.2 acres. While it lacks controlled spillways and outlet gates, the dam's risk assessment is considered moderate, indicating the importance of ongoing monitoring and maintenance to ensure its effectiveness in flood control efforts.
In light of the dam's purpose and design, water resource and climate enthusiasts can appreciate the significance of Coon Creek Lake Dam in mitigating flood risks in the region. Its location in an area with a drainage area of 5.41 square miles highlights the importance of maintaining infrastructure like this to safeguard communities and ecosystems from the impacts of extreme weather events. As a privately owned structure, the dam's continued operation and inspection by state regulatory agencies are essential to upholding its function and protecting the surrounding area from potential flooding 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.
