Summary
Built in 1977, this earth dam stands at a structural height of 27 feet and has a hydraulic height of 17 feet. It serves a primary purpose of water storage, with a capacity of 459 acre-feet and a normal storage level of 183 acre-feet. The dam covers a surface area of 22 acres and has a drainage area of 0.63 square miles.
The dam's hazard potential is classified as significant, but its condition assessment as of October 2020 was deemed satisfactory. The inspection frequency for Moss Creek #3 is every two years, with the last inspection conducted in October 2020. In case of emergencies, there are no outlet gates or an emergency action plan prepared for this dam. The risk assessment for Moss Creek #3 is categorized as moderate, with a DSAC assigned date currently unavailable.
Overall, Moss Creek #3 is a vital structure for water resource management in Tennessee, providing storage capacity and flood control along the Moss Creek river. With its state-regulated status and satisfactory condition assessment, efforts are in place to ensure the safety and integrity of this dam for the surrounding community and environment.

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.
