Summary
Constructed in 1963 with a height of 25 feet and a storage capacity of 833 acre-feet, this earth dam designed by USDA NRCS serves to protect the surrounding community from potential flooding events along the TR- Porters Creek stream.
Managed by the Mississippi Department of Environmental Quality, this dam is state-regulated, inspected, and enforced to ensure its structural integrity and safety. With a low hazard potential and a moderate risk assessment rating, the Porters Creek Watershed Structure 11 Dam remains a crucial piece of infrastructure in mitigating flood risks and maintaining the overall safety and well-being of the residents in Hebron.
As a part of the larger flood risk reduction system in the area, this dam plays a key role in managing water resources and mitigating climate-related hazards. With its design aimed at protecting the community and surrounding areas, the Porters Creek Watershed Structure 11 Dam stands as a testament to the importance of sustainable water resource management in the face of a changing climate.

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.
