Summary
Built in 1963 by USDA NRCS, this earthen dam serves primarily for flood risk reduction on the Porter Creek river. With a height of 24 feet and a storage capacity of 1696 acre-feet, it is designed with a buttress core and soil foundation, making it a crucial asset in managing water resources in the area.
Managed by the Mississippi Department of Environmental Quality, this dam is regulated and inspected regularly to ensure its safety and effectiveness. Despite being classified as having a low hazard potential, it is considered to have a moderate risk level, indicating the need for ongoing risk management measures. The dam features an uncontrolled spillway and outlet gates, contributing to its flood risk reduction purpose while posing minimal risk to the surrounding community.
As a part of the Memphis District, this dam plays a vital role in protecting the Tippah County area from potential flooding events. While its condition assessment is currently not rated, ongoing inspections and risk assessments are crucial to maintaining its functionality and ensuring the safety of the residents in the watershed. Porters Creek Watershed Structure 10 Dam stands as a testament to the collaborative efforts between local authorities and federal agencies in safeguarding water resources and mitigating climate-related risks in the region.

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.
