Summary
Built in 1960, this earth dam stands at a structural height of 32.4 feet with a hydraulic height of 20.6 feet. With a primary purpose of recreation, Greenbrier offers a storage capacity of 528 acre-feet, making it an essential water resource for the surrounding community. The dam's hazard potential is classified as high, but its condition assessment as of March 2021 is satisfactory, ensuring its operational safety.
Managed by the Tennessee Safe Dams Program, Greenbrier undergoes state regulation, permitting, inspection, and enforcement to maintain its integrity. Despite its moderate risk assessment level, the dam has a history of meeting guidelines and safety standards. With a surface area of 16 acres and a drainage area of 5.2 square miles, Greenbrier serves as a vital recreational site for locals and visitors alike. Its uncontrolled spillway and lack of outlet gates indicate a reliance on natural flow regulation, emphasizing the importance of proper monitoring and maintenance for long-term sustainability.
Greenbrier's location in the Nashville District and its proximity to the city of Greenbrier highlight its significance as a water management structure in the region. With a solid track record of inspections and a satisfactory condition, this dam plays a crucial role in providing recreational opportunities while also serving as a critical component of water resource management in Robertson County. As climate change continues to impact water resources, Greenbrier stands as a testament to the importance of efficient dam operation and maintenance in safeguarding communities against potential hazards.

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.
