Summary
Managed by the Tennessee Safe Dams Program, this earth dam was completed in 1977 and has a hydraulic height of 25 feet, a structural height of 30 feet, and a storage capacity of 61 acre-feet. With a surface area of 2.5 acres and a drainage area of 0.09 square miles, Anna Lake plays a crucial role in managing water flow and providing recreational opportunities in the area.
Despite being classified as a low hazard potential structure, Anna Lake is regularly inspected to ensure its safety and functionality. The dam is equipped with an uncontrolled spillway and has a satisfactory condition assessment as of September 2020. In case of emergencies, the dam has established protocols for risk assessment and management, reflecting a proactive approach towards ensuring the safety of the surrounding community. The reservoir's moderate risk level is monitored and managed through regular inspections and adherence to safety guidelines.
With its scenic location and important role in water resource management, Anna Lake stands as a testament to effective dam regulation and maintenance in Tennessee. Climate and water enthusiasts can appreciate the balance between environmental preservation and infrastructure development that this reservoir represents, making it a noteworthy site for those interested in sustainable water resource management practices in the region.

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.
