Summary
The dam stands at a height of 27.5 feet, with a hydraulic height of 24.5 feet, and has a storage capacity of 91 acre-feet. It is situated on the Stewart Branch river and serves the primary purpose of water storage, with a normal storage capacity of 69 acre-feet.
Despite being classified as having a low hazard potential, Lake Hill has a moderate risk assessment rating of 3. The dam has not been inspected since January 2019, with an inspection frequency of every 5 years. The structure features an uncontrolled spillway type with no outlet gates. While the condition assessment is currently listed as "Not Rated," there are no Emergency Action Plans (EAP) prepared or risk management measures specified for the dam.
Overall, Lake Hill presents an intriguing case study for water resource and climate enthusiasts, offering insights into the management and maintenance of privately owned dam structures in Tennessee. As a key component of the local water infrastructure, the dam's risk assessment and condition evaluation highlight the importance of regular inspections and emergency preparedness measures to ensure the safety and sustainability of water resources in the region.

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.
