Summary
The earth dam, completed in 1997, stands at a height of 46.5 feet with a hydraulic height of 43.1 feet. The reservoir boasts a maximum storage capacity of 258 acre-feet and covers a surface area of 13.4 acres. Despite being categorized as having a low hazard potential, the dam's condition was deemed satisfactory during its last inspection in October 2018.
With its purpose and associated structures unspecified, Lake Tahoo serves as a vital component of the local water infrastructure, contributing to the drainage area of 0.18 square miles. The spillway type is classified as uncontrolled, with a spillway width of zero. While the dam has not undergone significant modifications over the years, it remains subject to regular inspections every three years to ensure its structural integrity and safety. The risk assessment for Lake Tahoo indicates a moderate risk level of 3, prompting the need for ongoing risk management measures and monitoring.
In the event of an emergency, the dam's emergency action plan status, preparedness, and contact information are not specified. Despite this, Lake Tahoo continues to provide essential water storage and resource management functions, exemplifying the intersection of water resource management and climate resilience in the region. Enthusiasts of water resources and climate change will find Lake Tahoo to be a captivating case study in dam infrastructure and environmental stewardship within the Tennessee landscape.

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.
