Summary

George Lake in Cumberland, Tennessee, is a captivating water resource known for its recreational opportunities. The dam, completed in 1965, stands at a structural height of 58 feet and has a hydraulic height of 52.6 feet. The lake offers a normal storage capacity of 1801 acre-feet and covers a surface area of 125 acres, making it a popular destination for outdoor enthusiasts seeking water-based activities.

Managed by the Tennessee Safe Dams Program, St. George Lake is regulated, inspected, and enforced to ensure public safety. Despite its high hazard potential, the dam is currently assessed as satisfactory, with a moderate risk level. The surrounding area is monitored for risk assessment, and emergency preparedness measures are in place. With its uncontrolled spillway and serene location along Bagwell Branch, St. George Lake presents an ideal setting for recreation while maintaining a focus on safety and environmental stewardship in its operations.

For water resource and climate enthusiasts, St. George Lake offers a unique blend of natural beauty and human engineering. The dam's Earth construction type and its association with the Nashville District of the US Army Corps of Engineers add to its appeal. With a rich history dating back to the 1960s, St. George Lake continues to serve as a vital water source for the region while providing a picturesque backdrop for outdoor adventures.

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.
