Summary
The dam stands at a structural height of 25.5 feet and a hydraulic height of 10 feet, with a length of 1833 feet and a storage capacity of 1769 acre-feet. Despite its significant hazard potential, the dam is currently in satisfactory condition, as assessed during the last inspection in February 2020.
Managed by the Tennessee Safe Dams Program, Cub Creek #2a serves as a crucial infrastructure for flood control in the region, with a normal storage capacity of 160 acre-feet and a surface area of 39 acres. The dam's spillway type is uncontrolled, and it is monitored and inspected by the state regulatory agency on a regular basis. Additionally, the dam has no outlet gates and is primarily funded and operated by the state of Tennessee.
For water resource and climate enthusiasts, Cub Creek #2a represents a vital component of the region's water management infrastructure, providing essential flood risk reduction capabilities along the Cub Creek. With its earth structure and stone core, the dam has demonstrated its effectiveness in mitigating potential hazards, despite being classified as having a moderate risk level. The continued monitoring and maintenance of Cub Creek #2a highlight the importance of proactive dam management to ensure the safety and security of surrounding communities and ecosystems.

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.
