Summary

Completed in 2011, this earth dam serves primarily for recreational purposes, with a hydraulic height of 31 feet and a structural height of 37 feet. With a storage capacity of 1340 acre-feet and a surface area of 72 acres, Walden Ridge overlooks the tranquil Ferny Branch, providing a serene setting for water and climate enthusiasts to explore.

Managed by the Tennessee Safe Dams Program, Walden Ridge is subject to regular state inspections, enforcement, and permitting to ensure its safety and regulatory compliance. Despite its high hazard potential, the dam is currently rated as satisfactory in condition assessment, with a moderate risk level. The dam's spillway type is uncontrolled, and it has a drainage area of 0.64 square miles. In the event of an emergency, the dam's emergency action plan, including inundation maps and risk management measures, is crucial for safeguarding the surrounding communities.

With its picturesque location and important role in water resource management, Walden Ridge offers a glimpse into the intersection of human infrastructure and natural ecosystems. As a key feature in the Nashville District, this dam serves as a vital link between recreation, conservation, and hydraulic engineering, showcasing the delicate balance required to maintain sustainable water resources in the face of climate change challenges.

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.
