Summary
Built in 1976 by the USDA NRCS, this earth dam stands at a height of 28 feet and spans 2110 feet along Little Creek. With a storage capacity of 2643 acre-feet, the primary purpose of this dam is flood risk reduction in the area.
Managed by the Mississippi Department of Environmental Quality, the dam is classified as having a high hazard potential and is inspected every five years. Despite being rated in fair condition as of 2016, the dam poses a moderate risk due to its uncontrolled spillway type and outlet gates. The emergency action plan for the dam was last revised in February 2016, ensuring that measures are in place to respond to any potential incidents effectively.
For water resource and climate enthusiasts, Big Creek Water Park Dam serves as a vital structure in Jones County, Mississippi, providing flood risk reduction along with recreational opportunities at the water park. The dam's strategic location on Little Creek and its significant storage capacity make it a crucial element in the region's water management system. Ongoing inspections and risk assessments help to ensure the safety and effectiveness of this important infrastructure for both the local community and the environment.

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.
