Summary
Built in 1965 by the USDA NRCS, this earth dam serves a primary purpose of flood risk reduction along the Tributary of Porters Creek. With a hydraulic height of 11.5 feet and a structural height of 23.5 feet, the dam stands at 24 feet in total height and spans 1018 feet in length.
This dam has a low hazard potential and is deemed to be in satisfactory condition following its last inspection in July 2020. The Tennessee Safe Dams Program oversees the state regulation, inspection, and enforcement of Porters Creek #9, ensuring that it meets safety standards and poses minimal risk to surrounding areas. The dam has a normal storage capacity of 59 acre-feet, with a maximum storage of 572 acre-feet, covering a surface area of 17.2 acres and draining a 1.28 square mile watershed.
Despite its moderate risk assessment score of 3, Porters Creek #9 does not currently have an Emergency Action Plan in place. However, with regular inspections, state oversight, and a history of satisfactory condition assessments, this dam continues to play a crucial role in managing flood risks in the region. Water resource and climate enthusiasts can appreciate the engineering and management efforts that go into maintaining structures like Porters Creek #9 for the safety and protection of surrounding 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.
