Summary

2 Dam, also known as Ocoee No. 2 Lake, is a Federal-owned structure managed by the Tennessee Valley Authority. Built in 1913 by TN Electric Power, this timber crib dam stands at a height of 27 feet and has a length of 450 feet, holding a storage capacity of 175 acre-feet on the Ocoee River. The dam serves a primary purpose of hydroelectric power generation and recreation, with a spillway width of 436 feet and a maximum discharge capacity of 183,000 cubic feet per second.

With a high hazard potential, the Ocoee No. 2 Dam has undergone structural modifications in 1939 and is inspected every two years by the Tennessee Valley Authority. The dam features slide, tainter, and uncontrolled outlet gates to manage water flow. Despite its age, the condition assessment of the dam is not available, and it is classified as having a moderate risk level. The emergency action plan for the dam was last revised in July 2020, ensuring preparedness in the event of any unforeseen incidents. Enthusiasts of water resources and climate will find Ocoee No. 2 Dam to be a significant structure contributing to both energy generation and recreational activities along the Ocoee River.

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.
