Summary
The dam that forms the lake is classified as an Earth dam, with a hydraulic height of 51.6 feet and a structural height of 57 feet. Completed in 2000, the dam has a length of 800 feet and a storage capacity of 833 acre-feet, making it a significant water resource in the area.
With a surface area of 42.6 acres and a drainage area of 0.42 square miles, Tomlin Lake provides ample space for outdoor enthusiasts to enjoy activities such as fishing, boating, and wildlife observation. The dam's spillway, classified as uncontrolled, adds to the scenic beauty of the area. However, the dam is categorized as having a high hazard potential, requiring regular inspections and a moderate risk assessment score of 3.
Despite not being regulated or permitted by the state, Tomlin Lake remains a popular destination for those seeking recreational opportunities in a natural setting. The lake's condition assessment is listed as "Not Rated," emphasizing the importance of ongoing monitoring and maintenance to ensure the safety and enjoyment of visitors. For water resource and climate enthusiasts, Tomlin Lake offers a unique blend of leisure and natural beauty in the heart of Tennessee.

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.
