Summary
Managed by the Tennessee Safe Dams Program, this dam serves a critical purpose in controlling the flow of the Finley Ditch river or stream, with a drainage area of 0.1 square miles and a storage capacity of 47 acre-feet.
With a significant hazard potential and a satisfactory condition assessment, Finley Ditch dam is inspected every two years to ensure its safety and reliability. Despite its moderate risk level, the dam has no associated outlet gates and relies on an uncontrolled spillway type. The dam's emergency action plan status and risk management measures are currently undisclosed, highlighting the need for ongoing diligence and monitoring in protecting the surrounding area from potential flooding events.
For water resource and climate enthusiasts, Finley Ditch offers a fascinating case study in dam regulation and management. Its location in the Memphis District underlines the importance of state oversight in maintaining dam safety, while the dam's historical completion year and design specifications provide valuable insights into the region's water infrastructure. As a significant piece of Tennessee's water management system, Finley Ditch serves as a reminder of the critical role dams play in mitigating flood risks and ensuring water resource sustainability in the face of changing climatic conditions.

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.
