Summary
Built in 1966 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the Cub Creek. With a hydraulic height of 13.5 feet and a structural height of 26 feet, this dam has a storage capacity of 367 acre-feet and covers a surface area of 13.5 acres.
Despite not being regulated by the state, Cub Creek #3 has a significant hazard potential and is considered to have a moderate risk level. The dam, constructed with stone core and soil foundation, has not been rated for its current condition. With no outlet gates and an uncontrolled spillway type, Cub Creek #3 is inspected every 5 years to ensure its structural integrity. The dam has not been modified since its completion and does not have an Emergency Action Plan (EAP) in place.
For water resource and climate enthusiasts, Cub Creek #3 provides a fascinating example of a privately owned dam designed for flood risk reduction. Its location in Hardeman County, Tennessee, along the Cub Creek, showcases the importance of such structures in managing water resources and mitigating potential hazards. The dam's history, design features, and risk assessment highlight the complex interplay between infrastructure, natural resources, and environmental management in the region.

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.
