Summary
Completed in 1991, this dam stands at a structural height of 7 feet and has a storage capacity of 50 acre-feet, with a normal storage level of 35 acre-feet. The dam covers a surface area of 15 acres and has an uncontrolled spillway type with a width of 0.
Despite being categorized as having a low hazard potential and a moderate risk assessment, Tilley has not been rated for its condition assessment. The last inspection date was in June 2019, with an inspection frequency of 5 years. While the dam meets guidelines for emergency action planning, there is no current Emergency Action Plan (EAP) in place. The risk management measures and other risk assessment details for Tilley remain unspecified.
For water resource and climate enthusiasts, Tilley offers a glimpse into the infrastructure of water management in Tennessee. With its unique design and location, this dam serves as a vital asset in regulating water flow and storage in the region. However, the lack of recent condition assessments and emergency preparedness plans raise questions about the long-term sustainability and safety of this structure, highlighting the importance of ongoing monitoring and maintenance in the face of changing environmental conditions.

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.
