Summary

Built in 1970, Reed stands at a structural height of 21.2 feet and has a hydraulic height of 18.7 feet. With a storage capacity of 136 acre-feet, Reed serves a vital role in water resource management in the region, covering a surface area of 12.8 acres and draining an area of 0.42 square miles. Despite being classified as low hazard potential, Reed is subject to moderate risk and undergoes inspections every five years to ensure its structural integrity.

Managed by the Tennessee primary source agency, Reed does not fall under state jurisdiction or regulation. The dam features an uncontrolled spillway and no outlet gates, emphasizing its simplistic design. Although its condition is currently not rated, Reed meets guidelines for emergency action plans, with updated emergency contacts and regularly scheduled inspections. The risk assessment for Reed indicates a moderate level of risk, highlighting the importance of continued monitoring and risk management measures to ensure the safety and efficiency of this essential water resource infrastructure in Tennessee's Cumberland County.

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.
