Summary
Completed in 1979, this earth dam stands at a height of 35 feet and has a storage capacity of 1172 acre-feet. With a significant hazard potential and fair condition assessment, the dam plays a key role in flood risk reduction for the surrounding area.
Managed by the Mississippi Department of Environmental Quality, Big Creek Watershed Structure 13 Dam is state-regulated, inspected, and enforced to ensure its safety and effectiveness in flood management. With a spillway type of uncontrolled and uncontrolled outlet gates, the dam is designed to handle a maximum discharge of 410 cubic feet per second. Despite being built over four decades ago, the dam continues to serve its primary purpose effectively and has a moderate risk assessment rating.
As a vital component of the flood risk reduction infrastructure in Jasper County, Mississippi, Big Creek Watershed Structure 13 Dam plays a crucial role in protecting the local community from potential flooding events. With its strategic location and design features, the dam stands as a testament to effective water resource management and climate resilience efforts in the region. As climate change continues to impact weather patterns, structures like this dam will be essential in safeguarding communities and preserving valuable resources.

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.
