Summary
The earth dam, with a height of 22 feet and a hydraulic height of 20.5 feet, has a storage capacity of 377 acre-feet and a surface area of 25.7 acres. Managed by the local government, the dam is inspected every five years and has been rated as having a low hazard potential, with a moderate risk assessment score of 3.
Although the dam is uncontrolled, it is deemed to be in satisfactory condition and poses no immediate threat. With its buttress core design and unknown foundation type, Crown Mill Lake Dam stands as a testament to the importance of water resource management and climate resilience in the region. While not regulated by the state, the dam underscores the need for continued monitoring and adherence to safety protocols to ensure the protection of communities and ecosystems downstream.
As an integral part of the Nashville District, Crown Mill Lake Dam represents a valuable asset for the community, offering recreational opportunities and supporting the local economy. With its uncontrolled spillway and outlet gates, the dam provides a serene and picturesque setting for visitors to enjoy, while also serving as a reminder of the critical role that infrastructure plays in water resource management and climate adaptation efforts.

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.
