Twin Lake, located in Tipton, Tennessee, is a privately owned reservoir with a primary purpose of recreation.


Summary

The dam, completed in 1981, is an earth structure with a hydraulic height of 20 feet and a structural height of 24 feet. The lake has a storage capacity of 85 acre-feet, with a normal storage level of 55 acre-feet and a surface area of 6.9 acres.

Managed by the Tennessee Safe Dams Program, Twin Lake is subject to state regulations, inspections, and enforcement to ensure its safety and integrity. Despite being classified as having a low hazard potential, the dam is regularly assessed to be in satisfactory condition. The reservoir poses a moderate risk, with measures in place to manage any potential hazards.

Twin Lake provides a serene setting for recreational activities and wildlife habitat, with its tranquil waters offering a popular spot for fishing, boating, and nature appreciation. The reservoir's connection to Tribbig Creek adds to its ecological importance in the region, making it a valuable water resource for both human enjoyment and environmental sustainability.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
