Summary

Completed in 1949, the dam has a length of 540 feet and a storage capacity of 159 acre-feet. The lake covers an area of 18 acres and has a drainage area of 0.18 square miles, with the Wolf River tributary flowing nearby.

Managed by the Tennessee Safe Dams Program, Pine Lake is inspected biennially to ensure its satisfactory condition and significant hazard potential is mitigated. Despite its moderate risk assessment, the dam has been deemed to meet safety guidelines. The dam features an uncontrolled spillway and does not have outlet gates, emphasizing the importance of regular inspections and risk management measures to prevent potential emergencies.

Water resource and climate enthusiasts will be captivated by Pine Lake's historical significance as a water storage facility in Shelby County, Tennessee. With its picturesque setting and vital role in flood control and water supply management, Pine Lake stands as a testament to the enduring importance of dam infrastructure in supporting local communities and ecosystems.

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.
