Summary
The dam stands at a height of 22 feet and has a storage capacity of 646 acre-feet, serving the primary purpose of flood risk reduction. It is classified as an earth dam with a buttress core type, built on a soil foundation along the TR-Tallashua Creek.
Managed by the Mississippi Department of Environmental Quality, the dam is state-regulated and subject to regular inspections, with a fair condition assessment as of 2014. Despite a low hazard potential, the risk assessment shows a moderate level of risk, highlighting the importance of ongoing monitoring and maintenance. Chunky Creek Watershed Structure 18 Dam plays a crucial role in safeguarding the surrounding area from flooding, showcasing the collaboration between local government and federal agencies in water resource management.
With its uncontrolled spillway and outlet gates, this dam provides essential flood protection for the Neshoba County area. As a part of the Vicksburg District under the USACE, it exemplifies the commitment to environmental stewardship and public safety in water resource infrastructure. Chunky Creek Watershed Structure 18 Dam stands as a testament to the dedication of its designers and regulators in ensuring the resilience of the community against natural disasters.

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.
