Summary
Constructed in 1965 by the USDA NRCS, this Earth-type dam serves the primary purpose of Flood Risk Reduction along Porters Creek. With a hydraulic height of 20.5 feet and a structural height of 30.5 feet, the dam has a NID storage capacity of 968 acre-feet and covers a surface area of 40.9 acres.
Managed by the Tennessee Safe Dams Program, Porters Creek #16 has a low hazard potential and is currently in satisfactory condition as of the last inspection in July 2020. The dam's spillway type is uncontrolled, and it lacks outlet gates. Despite being categorized as having a moderate risk assessment level, the structure meets state permitting, inspection, and enforcement requirements, ensuring its continued safety and functionality for flood risk reduction in the region.
Located within the Memphis District of the USACE, Porters Creek #16 plays a crucial role in protecting the surrounding area from potential flooding events. With a history of responsible management and oversight by state regulatory agencies, this dam stands as a testament to the importance of maintaining water resources in a sustainable and secure manner for the benefit of both the environment and local communities.

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.
