Summary
The dam stands at a structural height of 20 feet and has a hydraulic height of 8.2 feet, providing a storage capacity of 120 acre-feet. Despite its age, the dam has a significant hazard potential and is categorized as having a moderate risk level.
The Napier Diversion lacks state regulation, inspection, and enforcement, posing potential challenges in maintaining its safety and integrity. The dam features an uncontrolled spillway type and is not equipped with outlet gates. The surrounding area covers a surface area of 6 acres and has a drainage area of 21.7 square miles. With its historical significance and recreational value, the Napier Diversion serves as a vital asset for water resource and climate enthusiasts interested in exploring the intersection of human infrastructure and natural landscapes in Tennessee.
Although the condition assessment of the Napier Diversion is currently not rated, its risk management measures and emergency action plan status are unclear. As water resource and climate enthusiasts engage with the site, there is an opportunity to advocate for increased oversight and maintenance to ensure the safety and sustainability of this historic dam. By understanding the complexities of managing aging infrastructure like the Napier Diversion, enthusiasts can contribute to the preservation and responsible stewardship of water resources in the region.

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.
