Summary
Built in 1969, this Earth dam stands at a structural height of 16.9 feet with a hydraulic height of 13.6 feet, providing storage of up to 44 acre-feet of water from Turkey Creek. The pond covers a surface area of 5 acres and has a drainage area of 0.16 square miles.
With a significant hazard potential and a moderate risk assessment score of 3, Lewis Lacy Pond has not been rated for its condition and has not had an Emergency Action Plan reassessment since January 2019. Despite being unregulated and uninspected by the state, the pond serves as a vital water resource for the local community and wildlife. While it lacks associated structures and formal purposes, the pond remains a valuable asset for water storage and conservation in the region.
Enthusiasts of water resources and climate will find Lewis Lacy Pond to be a hidden gem in Decatur, Tennessee, offering a unique Earth dam structure with a controlled spillway. While there are no outlet gates or locks, the pond provides essential storage for up to 44 acre-feet of water, contributing to the overall water management system in the area. As a privately owned entity, it presents an opportunity for environmental stewardship and conservation efforts to ensure its continued function and safety for generations to come.

Dam Data Reference
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.
